SAFE OPERATION

1. BEFORE OPERATING THE TRACTOR

1. Know your equipment and its limitations. Read this entire manual before attempting to start and operate the tractor.
2. Pay special attention to the danger, warning and caution labels on the tractor.
3. Do not operate the tractor or any implement attached to it while under the influence of alcohol, medication, controlled substances or while fatigued.
4. Before allowing other people to use your tractor, explain how to operate and have them read this manual before operation.
5. Never wear loose, torn, or bulky clothing around tractor. It may catch on moving parts or controls, leading to the risk of an accident. Use additional safety items, e.g. hard hat, safety boots or shoes, eye and hearing protection, gloves, etc., as appropriate or required.
6. Do not allow passengers to ride on any part of the tractor at anytime. The operator must remain in the tractor seat during operation.
7. Check brakes, clutch, linkage pins and other mechanical parts for improper adjustment and wear. Replace worn or damaged parts promptly. Check the tightness of all nuts and bolts regularly. (For further details, see 'MAINTENANCE' section.)
8. Keep your tractor clean. Dirt, grease, and trash build up may contribute to fires and lead to personal injury.
9. Use only implements meeting the specifications listed under 'IMPLEMENT LIMITATIONS' in this manual or implements approved by KUBOTA.
10. Use proper weights on the front or rear of the tractor to reduce the risk of upsets. When using the front loader, put an implement or ballast on the 3-point hitch to maintain proper balance and braking. Follow the safe operating procedures specified in the implement or attachment manual.
11. The narrower the tread, the greater the risk of a tractor upset. For maximum stability, adjust the wheels to the widest practical tread width for your application. (See 'TIRES, WHEELS AND BALLAST' section.)
12. Do not modify the tractor. Unauthorized modification may affect the function of the tractor, which may result in personal injury.
13. Do not make any modifications to the engine or emission components as they may result in damage and malfunctions such as: A Damage to the powertrain from excessive engine output. A Engine overheating caused by exceeding the engine cooling performance capabilities. A Malfunctions of the exhaust gas aftertreatment control devices. Modifications to the engine and its emission components may violate emission regulations and are subject to fines and penalties. Kubota and its affiliates are not liable for any damage, malfunction or accidents caused by modifications to the engine or emission components.

C CAB, ROPS

1. KUBOTA recommends the use of a CAB or Roll Over Protective Structures (ROPS) and seat belt in almost all applications. This combination will reduce the risk of serious injury or death, should the tractor be upset. Check for overhead clearance which may interfere with a CAB or ROPS.
2. If the CAB or ROPS is loosened or removed for any reason, make sure that all parts are reinstalled correctly before operating the tractor.
3. Never modify or repair any structural member of a CAB or ROPS because welding, bending, drilling, grinding, or cutting may weaken the structure.
4. A damaged CAB or ROPS structure must be replaced, not repaired or revised.
5. If any structural member of the CAB or ROPS is damaged, replace the entire structure at your local KUBOTA Dealer.
6. Always use the seat belt if the tractor has a CAB or ROPS. Do not use the seat belt if a foldable ROPS is down or there is no ROPS. Check the seat belt regularly and replace if frayed or damaged.

2. OPERATING THE TRACTOR

Operator safety is a priority. Safe operation, specifically with respect to overturning hazards, entails understanding the equipment and environmental conditions at the time of use. Some prohibited uses which can affect overturning hazards include traveling and turning with implements and loads carried too high etc. This manual sets forth some of the obvious risks, but the list is not, and cannot be, exhaustive. It is the operator's responsibility to be alert for any equipment or environmental condition that could compromise safe operation.

C Starting

1. Always sit in the operator's seat when starting engine or operating levers or controls. Adjust seat per instructions in the operating the tractor section. Never start engine while standing on the ground.
2. Before starting the engine, make sure that all levers (including auxiliary control levers) are in their neutral positions, that the parking brake is engaged, and that both the clutch and the Power Take-Off (PTO) are disengaged or 'OFF'. Fasten the seat belt if the tractor has a CAB, a fixed ROPS or a foldable ROPS in the upright and locked position.
3. Do not start engine by shorting across starter terminals or bypassing the safety start switch. Machine may start in gear and move if normal starting circuitry is bypassed.
4. Do not operate or idle engine in a non-ventilated area. Carbon monoxide gas is colorless, odorless, and deadly.
5. Check before each use that operator presence controls are functioning correctly. Test safety systems. (See 'Checking Engine Start System' in 'EVERY 50 HOURS' in 'PERIODIC SERVICE' section.) Do not operate unless they are functioning correctly.

C Working

1. Pull only from the drawbar. Never hitch to axle housing or any other point except drawbar; such arrangements will increase the risk of serious personal injury or death due to a tractor upset.
2. For trailing PTO-driven implements, set the drawbar to the towing position.
3. Attach pulled or towed loads to the drawbar only.
4. Keep all shields and guards in place. Replace any that are missing or damaged.
5. Avoid sudden starts. To avoid upsets, slow down when turning, on uneven ground, and before stopping.
6. The tractor cannot turn with the differential locked and attempting to do so could be dangerous.
7. Do not operate near ditches, holes, embankments, or other ground surface features which may collapse under the tractor's weight. The risk of tractor upset is even higher when the ground is loose or wet. Tall grass can hide obstacles, walk the area first to be sure.
8. Watch where you are going at all times. Watch for and avoid obstacles. Be alert at row ends, near trees, and other obstructions.
9. When working in groups, always let the others know what you are going to do before you do it.
10. Never try to get on or off a moving tractor.
11. Always sit in the operator's seat when operating levers or controls.
12. Do not stand between tractor and implement or trailed vehicle unless parking brake is applied.
13. Whenever the tractor is operated in reverse, confirm visibility to the rear.

C Instructional seat (if equipped)

1. Always wear your seat belt and stabilize your body by holding the handrail on the CAB frame.
2. It is not intended to carry children nor any other person for any other purpose.
3. The left hand door must be closed at all time whenever the instructional seat is occupied and the tractor is in motion.
4. Do not permit others to ride, except on the designated instructional seat.
5. Use caution to avoid the risks of obstructing operator's view, falling from the machine and interfering with controls.
6. Do not start and stop the tractor suddenly, nor take sharp turn.
7. Do not use the instructional seat if the seat belt or the door lock fails to function.
8. Do not use the instructional seat for transport.
9. Fold the instructional seat when not in use, because otherwise the operator may tip over when he or she gets on or off the CAB.
10. When opening and closing the door from the instructional-seat-sitting position, move the door slowly. This is to prevent his or her hand(s) from getting caught by the door or his or her body to hit against the door.

C Safety for children

Tragedy can occur if the operator is not alert to the presence of children. Children generally are attracted to machines and the work they do.

1. Never assume that children will remain where you last saw them.
2. Keep children out of the work area and under the watchful eye of another responsible adult.
3. Be alert and shut your machine down if children enter the work area.
4. Never carry children on your machine. There is no safe place for them to ride. They may fall off and be run over or interfere with your control of the machine.
5. Never allow children to operate the machine even under adult supervision.
6. Never allow children to play on the machine or on the implement.
7. Use extra caution when backing up. Look behind and down to make sure area is clear before moving.

C Operating on slopes

Slopes are a major factor related to loss-of-control and tipover accidents, which can result in severe injury or death. All slopes require extra caution.

1. To avoid upsets, always back up steep slopes. If you cannot back up the slope or if you feel uneasy on it, do not operate on it. Stay off slopes too steep for safe operation.
2. Driving forward out of a ditch, mired condition or up a steep slope increases the risk of a tractor to be upset backward. Always back out of these situations. Extra caution is required with 4-wheel drive models because their increased traction can give the operator false confidence in the tractor's ability to climb slopes.
3. Keep all movement on slopes slow and gradual. Do not make sudden changes in speed, direction or apply brake and make sudden motions of the steering wheel.
4. Avoid disengaging the clutch or changing gears speed when climbing or going down a slope. If on a slope disengaging the clutch or changing gears to neutral could cause loss of control.
5. Special attention should be made to the weight and location of implements and loads as such will affect the stability of the tractor.
6. To improve stability on slope, set widest wheel tread as shown in 'TIRES, WHEELS AND BALLAST' section. Follow recommendations for proper ballasting.
7. To avoid free wheeling: A Do not shift the shuttle lever while on a slope. A Stop completely by using the brake and by depressing the clutch pedal, then shift the shuttle lever. A Start off after selecting shuttle direction, by releasing the clutch pedal.

C Driving the tractor on the road

1. Lock the 2 brake pedals together to help assure straight-line stops. Uneven braking at road speeds could cause the tractor to tip over.
2. Check the front wheel engagement. The braking characteristics are different between 2 and 4-wheel drive. Be aware of the difference and use carefully.
3. Always slow the tractor down before turning. Turning at high speed may tip the tractor over.
4. Make sure that the Slow Moving Vehicle (SMV) sign is clean and visible. Use hazard lights and turn signals as required.
5. On public roads use the SMV emblem and hazard lights, if required by local traffic and safety regulations.
6. Observe all local traffic and safety regulations.
7. Turn the headlights on. Dim them when meeting another vehicle.
8. Drive at speeds that allow you to maintain control at all times.
9. Do not apply the differential lock while traveling at road speeds. The tractor may run out of control.
10. Avoid sudden motions of the steering wheel as they can lead to a dangerous loss of stability. The risk is especially great when the tractor is traveling at road speeds.
11. Do not operate an implement while the tractor is on the road. Lock the 3-point hitch in the raised position.
12. When towing other equipment, use a safety chain and place an SMV emblem on it as well.
13. Set the 3-point hitch lowering speed knob in the 'LOCK' position to hold the implement in the raised position.

3. PARKING THE TRACTOR

1. Disengage the PTO, lower all implements to the ground, place all control levers in their neutral positions, set the parking brake, stop the engine, remove the key from the ignition and lock the cab door (if equipped). Leaving transmission in gear with the engine stopped will not prevent tractor from rolling.
2. Make sure that the tractor has come to a complete stop before dismounting.
3. Avoid parking on steep slopes, if at all possible park on a firm and level surface; if not, park across a slope and chock the wheels. Failure to comply with this warning may allow the tractor to move and could cause injury or death.

4. OPERATING THE PTO

1. Wait until all moving components have completely stopped before getting off the tractor, connecting, disconnecting, adjusting, cleaning, or servicing any PTO driven equipment.
2. Keep the PTO shaft cover in place at all times. Replace the PTO shaft cap when the shaft is not in use.
3. Before installing or using PTO driven equipment, read the manufacturer's manual and review the safety labels attached to the equipment. To prevent PTO driven equipment from improper or unsafe use, select the lower speed (540rpm) unless the higher one is specifically recommended as safe by the equipment manufacturer.
4. When operating stationary PTO driven equipment, always apply the tractor parking brake and place chocks behind and in front of the rear wheels. Stay clear of all rotating parts. Never step over rotating parts.

5. USING 3-POINT HITCH

1. Use the 3-point hitch only with equipment designed for the appropriate category of 3-point hitch usage.
2. When using a 3-point hitch mounted implement, be sure to install the proper counterbalance weight on the front of the tractor.
3. To avoid injury from separation: Do not extend lift rod beyond the groove on the threaded rod.

6. SERVICING THE TRACTOR

Before servicing the tractor, park it on a firm, flat and level surface, set the parking brake, lower all implements to the ground, place the gear shift lever in neutral, stop the engine and remove the key.

1. Allow the tractor time to cool off before working on or near the engine, muffler, radiator, etc.
2. Do not remove radiator cap while coolant is hot. When cool, slowly rotate cap to the first stop and allow sufficient time for excess pressure to escape before removing cap completely. If the tractor has a coolant recovery tank, add coolant or water to the recovery tank, not the radiator. (See 'Checking Coolant Level' in 'DAILY CHECK' in 'PERIODIC SERVICE' section.)
3. Always stop the engine before refueling. Avoid spills and overfilling.
4. Do not smoke when working around battery or when refueling. Keep all sparks and flames away from battery and fuel tank. The battery presents an explosive hazard, because it gives off hydrogen and oxygen especially when recharging.
5. Before 'jump starting' a dead battery, read and follow all of the instructions. (See 'JUMP STARTING' in 'OPERATING THE ENGINE' section.)
6. Keep first aid kit and fire extinguisher handy at all times.
7. Disconnect the battery's ground cable before working on or near electric components.
8. To avoid the possibility of battery explosion, do not use or charge the refillable type battery if the fluid level is below the LOWER (lower limit level) mark. Check the fluid level regularly and add distilled water as required so that the fluid level is between the UPPER and LOWER levels.
9. To avoid sparks from an accidental short circuit, always disconnect the battery's ground cable (-) first and reconnect it last.
10. Do not attempt to mount a tire on a rim. This should be done by a qualified person with the proper equipment.
11. Always maintain the correct tire pressure. Do not inflate tires above the recommended pressure shown in the operator's manual.
12. Securely support the tractor when either changing wheels or adjusting the wheel tread width.
13. Make sure that wheel bolts have been tightened to the specified torque.
14. Do not work under any hydraulically supported devices. They can settle, suddenly leak down, or be accidentally lowered. If it is necessary to work under tractor or any machine elements for servicing or adjustment, securely support them with stands or suitable blocking beforehand.
15. Escaping hydraulic fluid under pressure has sufficient force to penetrate skin, causing serious personal injury. Before disconnecting hydraulic lines, be sure to release all residual pressure. Before applying pressure to the hydraulic system, make sure that all connections are tight and that all lines, pipes, and hoses are free of damage.
16. Fluid escaping from pinholes may be invisible. Do not use hands to search for suspected leaks; use a piece of cardboard or wood. Use of safety goggles or other eye protection is also highly recommended. If injured by escaping fluid, see a medical doctor at once. This fluid will produce gangrene or severe allergic reaction.
17. Do not open high-pressure fuel system. High-pressure fluid remaining in fuel lines can cause serious injury. Do not disconnect nor attempt to repair fuel lines, sensors, or any other components between the high-pressure fuel pump and injectors on engines with high pressure common rail fuel system.
18. To avoid hazardous high voltage, turn the key switch to the OFF position if it is necessary to check to repair the computer, harness or connectors.
19. During Diesel Particulate Filter (hereinafter called DPF) regenerating operations, exhaust gases and exhaust filter components reach temperatures hot enough to burn people, or ignite or melt common materials.
20. Keep the tractor away from people, animals or structures which may be susceptible to harm or damage from hot exhaust gases.
21. To prevent fires, keep the DPF muffler / SCR device and their surroundings clear of anything flammable and keep clean at all times. [Selective Catalytic Reduction (hereinafter called SCR)]
22. During regeneration, white exhaust gas may be visible. Do not allow regeneration in a non-ventilated space.
23. During regeneration, do not leave the tractor.
24. The improper disposal or burning of waste causes environmental pollution and can be punishable by your local laws and regulations. A When draining fluids from the tractor, place a container underneath the drain port. A Do not pour waste onto the ground, down a drain, or into any water source (such as rivers, streams, lakes, marshes, seas and oceans). A Waste products such as used oil, fuel, coolant, hydraulic fluid, aqueous urea solution (DEF (AdBlue)), refrigerant, solvent, filters, rubber, batteries and harmful substances, can harm the environment, people, pets and wildlife. Please dispose properly. See your local recycling center or KUBOTA Dealer to learn how to recycle or get rid of waste products.

A To protect the battery and the starter, make sure that the starter is not continuously turned for more than 10 seconds.

EXHAUST AFTERTREATMENT DEVICES

B Dual Exhaust Aftertreatment Devices

Particulate matter (PM) and black smoke contained in exhaust gases are trapped and removed by the DPF (Diesel Particulate Filter) muffler. The SCR system then decomposes residual nitrogen oxides (NOx) into harmless nitrogen (N2) and water (H2O) for purification. This dual exhaust gas purifying device provides for clean exhaust gas at low fuel consumption.

To avoid personal injury or death:
A During Diesel Particulate Filter (DPF) regenerating operations, exhaust gases and exhaust filter components reach temperatures hot enough to burn people, or ignite or melt common materials.
A Keep tractor away from people, animals or structures which may be susceptible to harm or damage from hot exhaust gases.
A During regeneration, white exhaust gases may be visible. Do not allow regeneration in a non ventilated garage or confined area.
A During regeneration, do not leave the tractor.

DIESEL PARTICULATE FILTER (DPF) MUFFLER

This tractor is equipped with an engine with a DPF (Diesel Particulate Filter) muffler which serves to reduce hydrocarbons, carbon monoxide and other gases, all of which are contained in diesel engine emissions, to harmless carbon dioxide and water. The DPF also traps PM (particulate matter). Please handle exhaust aftertreatment devices correctly and in an environmentally responsible manner.

B Handling Points

When a specific amount of PM (particulate matter) has accumulated in the DPF muffler, it is necessary to refresh the DPF muffler by burning the PM inside it. This burning off work is called 'Regeneration'. To extend operating time to reach this regeneration, and to avoid DPF muffler trouble, make sure to observe the following handling matters.

C Fuel

Be sure to use Ultra Low Sulfur Fuel (S15).
A Use of diesel fuel other than Ultra Low Sulfur Fuel may adversely affect the engine and DPF performance. Use of fuels other than Ultra Low Sulfur Fuel (S15) may not meet regulations for your region.

C Engine oil

Use DPF-compatible oil (CJ-4) for the engine.
A If any engine oil other than CJ-4 is used, the DPF may become clogged earlier than expected and the fuel economy may drop.

C Prohibition of unnecessary idling operation

Generally, the lower the engine speed, the lower the exhaust gas temperature is, so the PM contained in exhaust gas will not be burnt, and begins to accumulate. Therefore, don't idle unnecessarily.

C Regeneration

When there is 'Regeneration' instruction sign by lamp or buzzer, immediately perform the required procedure for regeneration.
A Interrupting the regeneration cycle or continued operation by ignoring the warning signs may cause DPF and engine damage.

B DPF Regeneration Process

DPF regeneration process can be performed by choosing from 'Auto Regeneration' or 'Regeneration inhibit' mode according to your job conditions. For jobs not affected by hot gases emitted during regeneration, the 'Auto Regeneration' is advisable.

C Auto Regeneration Mode

When starting the engine (switch operation is unnecessary), the 'Auto Regeneration' mode is automatically activated. With the auto regeneration mode on, when a specific amount of PM has accumulated, and the regeneration conditions are satisfied (See the 'Tips on Diesel Particulate Filter [DPF] Regeneration'), the DPF will be automatically regenerated whether the tractor is in motion or parked. By this way, work efficiency is improved. For details of auto regeneration, refer to 'Operating Procedure for Auto Regeneration Mode' section.

C Regeneration Inhibit Mode

After starting the engine, if the 'DPF INHIBIT switch' is pressed to turn on the switch lamp, the 'Regeneration inhibit' mode will be activated. With 'Regeneration Inhibit' mode on, the PM which has accumulated inside the DPF will not be burnt, unless the operator performs the regeneration work manually. The 'Regeneration Inhibit' mode is effective for work in poorly ventilated work spaces. For details of regeneration prohibition, refer to 'Operating Procedure for Regeneration Inhibit Mode' section.

A If stop the engine once, the 'Auto Regeneration' mode will be activated.

B Operating Procedure for Auto Regeneration Mode

(1) Parked regeneration switch (2) DPF INHIBIT switch (3) Regeneration indicator (4) Parked regeneration indicator (5) Engine RPM increase indicator (6) Engine warning indicator

C Regeneration Operating Procedure

1. Start the engine. (Make sure that the DPF INHIBIT switch lamp is 'OFF'.)
2. Switch lamp OFF: Auto Regeneration Mode activated. Switch lamp ON: Regeneration Inhibit Mode activated.
3. When the regeneration indicator ? starts flashing: A specific amount of PM has built up in the DPF. Continue to operate the tractor, and the regeneration process will begin automatically, make sure the working place is in a safe area as DPF and exhaust temperature will rise.
4. When the engine rpm increase indicator ⬆️ starts flashing: Keep on working and increase the engine rpm until the indicator turns 'OFF'.

A When the engine is started, the 'Auto Regeneration' mode is automatically activated.
A 'Regeneration Inhibit' mode is activated, when the DPF INHIBIT switch is pushed after the engine is started.
A Even if the Auto Regeneration Mode is selected, DPF regeneration may not begin because system requirements have not been satisfied.
A The engine rpm increase indicator is used as a guide to satisfy the regeneration conditions. If the engine load is too heavy, the engine rpm increase indicator may continue to flash, even though regeneration system conditions are satisfied and regeneration may begin automatically. (See the 'Tips on Diesel Particulate Filter [DPF] Regeneration')

C PM Warning Level and Required Procedures During Auto Regeneration Mode

When the PM level has built up in the DPF, the regeneration cycle will begin automatically. If the regeneration cycle is interrupted or the regeneration conditions are not satisfied, the buzzer starts sounding and the indicator display changes in response to the PM level in order to prompt the operator to perform the required procedure listed below.

A Once the regeneration level has been reached, immediately perform the required procedure for regeneration. Interrupting the regeneration cycle or continued operation by ignoring the warning signs may cause DPF and engine damage.

B Operating Procedure for Regeneration Inhibit Mode

(1) Parked regeneration switch (2) DPF INHIBIT switch (3) Regeneration indicator (4) Parked regeneration indicator (5) Engine RPM increase indicator (6) Engine warning indicator

C Regeneration Operating Procedure

1. Start the engine.
2. Press the DPF INHIBIT switch ?, and the switch lamp illuminates.
3. Switch lamp ON: Regeneration Inhibit Mode selected. Switch lamp OFF: Auto Regeneration Mode selected.
4. When the parked regeneration indicator ?️ starts flashing: A specific amount of PM has accumulated in the DPF muffler. Move the tractor to a safe place and activates the DPF muffler. Follow the 'Operating Procedure for Parked Regeneration' procedure.

C PM Warning Level and Required Procedures In the Regeneration Inhibit Mode

The buzzer starts sounding and the indicator display changes in response to the PM level in order to prompt the operator to perform the required procedure listed below.

A Once the regeneration level has been reached, immediately perform the required procedure for regeneration. Interrupting the regeneration cycle or continued operation by ignoring the warning signs may cause DPF and engine damage.

B Operating Procedure for Parked Regeneration

1. Park the tractor in a safe area away from buildings, people, and animals.
2. Apply the parking brake.
3. Set the shuttle shift lever to the neutral position.
4. Turn 'OFF' the PTO clutch control switch.
5. Return the engine rpm to the idle speed.
6. Lower the implement to the ground.
7. Press the DPF INHIBIT switch ?, and the switch lamp turns 'OFF'.
8. When the regeneration conditions are satisfied (2 to 5 and 7 mentioned above), the parked regeneration switch lamp ?️ starts flashing.
9. Press the parked regeneration switch ?️ to start the regeneration cycle. (The switch lamp will stop flashing and remain 'ON' constantly during the cycle.)
10. The engine rpm will automatically rise, and the regeneration process will begin.
11. Both indicators ? ?️ stay 'ON' while regenerating the DPF. They turn 'OFF' when the cycle is complete.
12. After the lamp turns 'OFF', normal tractor work may resume.

When driving in 'Regeneration Inhibit' mode, press the DPF INHIBIT switch to turn on the switch lamp.

A During the regeneration cycle, do not touch the above levers, and switches (in steps 2, 3, 4), nor change the engine rpm other than an emergency stop. Otherwise, the regeneration will be interrupted.
A Never leave the tractor when parked regeneration process is activated.
A If the parked regeneration cycle is interrupted, the engine rpm is fixed at the idling level for about 30 seconds. For this period, keep the hand throttle lever and foot throttle pedal at the idle position. Do not move them. They will function again in 30 seconds.
A If one of the following conditions applies to the tractor, the Parked Regeneration will not function. (See 'Warning Indication and its Countermeasure' in 'SELECTIVE CATALYTIC REDUCTION (SCR) SYSTEM' in 'OPERATING THE ENGINE' section.)

1. DEF (AdBlue) level and quality warning indicator on the LCD lights up and 'Lv.1' or 'Lv.2' is being displayed (Limited Engine Output).
2. SCR system warning indicator lights up and the DTC are being displayed on the LCD.
3. Freeze icon of DEF (AdBlue) or Limited Engine Output is displayed on the LCD.

A DTC (Diagnostic Trouble Code) DTC can be used to diagnose the problem in engine and SCR system. (e.g. 'ENG P-208B': The code beginning with the letter 'P' or 'U' is the DTC)

B Tips on Diesel Particulate Filter (DPF) Regeneration

A Operation

The higher in speed or load the engine operates, the higher the exhaust temperature rises. As a result, particulate matter (PM) inside the DPF is consumed, therefore the regeneration process is required less frequently over time. The lower in speed or load the engine operates, the lower the exhaust temperature. Accordingly, less particulate matter (PM) inside the DPF is consumed, therefore more accumulation of PM will occur, which requires frequent regeneration, therefore avoid prolonged idling if possible.

A Necessary conditions for 'Regeneration'

When conditions below are all satisfied, regeneration will start. However, if even one condition is deviated during the process, the regeneration will be interrupted.

1. The engine coolant temperature.
2. The DPF temperature.
3. The engine speed is 1200 rpm or higher.

A Usually it takes 15-20 minutes to complete the regeneration cycle. Actual regeneration time may depend on ambient temperature, exhaust temperature and engine speed.
A It is recommended to do the regenerating while the engine is warm.
A Do not unnecessarily start and interrupt the regeneration process. Otherwise, a small amount of fuel becomes mixed with the engine oil, which degrades the oil quality.
A While the DPF is being regenerated, the engine air flow rate is automatically limited to keep up the exhaust temperature. Because of this the engine may sound differently, this is normal for this engine.
A Just after the regeneration has ended, the DPF muffler remains hot. It is advisable to keep the engine running for about 5 minutes to allow cooling of the exhaust components.

SELECTIVE CATALYTIC REDUCTION (SCR) SYSTEM

B Outline of the SCR System

A The SCR system is intended to reduce or eliminate nitrogen oxides (NOx) from diesel exhaust gas. The system uses Diesel Exhaust Fluid (DEF) as a reducing agent and hydrolyzes it with the heat of exhaust gas to produce ammonia (NH3). The generated ammonia reduces NOx and decomposes them into nitrogen and water for emissions reduction. Due to this NOx reduction from the exhaust gas, the odor of the exhaust gas discharged from the SCR device differs from that of conventional diesel engines.
A Diesel Exhaust Fluid (DEF) is sold under many brand names, with one of the more common ones being AdBlue. In the text, DEF is described as DEF (AdBlue).
A DEF (AdBlue) freezes below -11C (12F), but this does not affect the start-up of the engine. The frozen DEF (AdBlue) is thawed by the heat of the engine coolant while the engine is running.
A Modifying the SCR system is a violation of local laws and regulations. Do not modify the SCR system for any reason, as doing so could result in monetary sanctions and fines.
A Do not run the engine when the DEF tank is empty.
A If the remaining amount of DEF (AdBlue) is insufficient, the quality is poor, or if an abnormality occurs in the SCR system, the auto regeneration and parked regeneration functions of the Diesel Particulate Filter (DPF) muffler may not operate properly.

B DEF (AdBlue)

A The DEF (AdBlue), used as a reducing agent for the SCR system, is a 32.5% aqueous urea solution.
A No qualification is needed for handling DEF (AdBlue). In addition, DEF (AdBlue) is not designated as a hazardous material.
A Use DEF (AdBlue) that conforms to ISO 22241.
A In North America, the high-grade NOx reducing agent (aqueous urea solution) is sold under the name of DEF (Diesel Exhaust Fluid). In Europe and in Japan, aqueous urea solution is sold under the brand name AdBlue.

B Handling DEF (AdBlue)

To avoid personal injury, note the following when handling DEF (AdBlue):

• A If DEF (AdBlue) gets into your eyes, immediately rinse your eyes with a large amount of water for at least 15 minutes and consult a doctor.
• A Do not swallow DEF (AdBlue). If you have accidentally swallowed DEF (AdBlue), seek medical attention immediately.
• A If DEF (AdBlue) gets on your skin, rinse immediately with water. In rare cases, DEF (AdBlue) may irritate the skin.
• A If DEF (AdBlue) gets on your clothes or shoes, wash it off immediately. Simply wiping off or leaving DEF (AdBlue) on clothes or shoes will leave a white residue. For more details, obtain and read the Safety Data Sheet (SDS) from the DEF (AdBlue) supplier.

If you spill DEF (AdBlue), immediately rinse with clean water. If left untouched, DEF (AdBlue) may rust metal parts or corrode painted surfaces. Also, resin and rubber parts may be deformed.

B Quality of DEF (AdBlue)

A If the DEF (AdBlue) emits a strong ammonia odor, the quality of the fluid may have deteriorated. To check the quality of the DEF (AdBlue), check the odor of the DEF (AdBlue) in the DEF tank once every 3 months.
A If the DEF (AdBlue) in the DEF tank emits a strong ammonia odor, drain all DEF (AdBlue) from the DEF tank into a container. (See 'Draining DEF (AdBlue)' in 'SELECTIVE CATALYTIC REDUCTION (SCR) SYSTEM' in 'OPERATING THE ENGINE' section.) After draining the DEF (AdBlue), flush the inside of the DEF tank with distilled water, then refill the DEF tank with new or high-quality DEF (AdBlue).
A When you do not use the machine for more than 3 months, drain all DEF (AdBlue) from the DEF tank.

A Purchasing DEF (AdBlue) from a Kubota Dealer is recommended. The product is also available at gas stations, truck stops and specialty shops. Be sure to use an ISO 22241 compliant product. Using noncompliant products may lead to engine failure.
A The appropriate environment for storing DEF (AdBlue) is between -5C to 30C (23F to 86F). See the following table for more information about the storage life of DEF (AdBlue). To prevent the shortening of the DEF (AdBlue) storage life, avoid storing the DEF (AdBlue) in environments that exceed 30C (86F). Details regarding the storage of DEF (AdBlue) can be found in a different section. (See 'Storing Purchased DEF (AdBlue)' and 'Storing DEF (AdBlue) in the DEF Tank' in 'SELECTIVE CATALYTIC REDUCTION (SCR) SYSTEM' in 'OPERATING THE ENGINE' section.)

A Do not dilute the DEF (AdBlue) fluid.
A DEF (AdBlue) of deteriorated quality may cause a drop in engine output or an engine malfunction.

A If distilled water is not available for flushing the inside of the DEF tank, rinse with clean water first, then rinse thoroughly with DEF (AdBlue) again. Afterward, replenish with new or high-quality DEF (AdBlue).
A Be sure to turn the key switch to 'OFF' position when replacing the DEF (AdBlue).

B Warning Indication and its Countermeasure

C Warning display when the remaining amount of DEF (AdBlue) is low

This machine controls the engine output according to the remaining amount of DEF (AdBlue) to comply with emission regulations. After starting the engine, check the remaining amount of DEF (AdBlue) with the DEF (AdBlue) gauge located on the instrument panel. If the DEF (AdBlue) runs low, the low-level warning icon flashes and the buzzer sounds. If you continue running the machine in its current state, the engine output will be limited to about 50%. If operation is continued, the engine will be limited to idling. These limitations are stipulated in conformity with the emission controls of each country and territory.

(1) DEF (AdBlue) gauge (2) DEF (AdBlue) level and quality warning indicator (3) SCR system warning indicator (4) Low-level warning icon of DEF (AdBlue)

C SCR system inducement display on the LCD

(1) SCR system warning icon (2) Engine output level (3) Time limit to next level or remaining DEF (AdBlue) (4) Performance monitor (Error code and DTC)

C SCR system icon appearing on inducement display

• Low-level icon of DEF (AdBlue)
• Poor-quality icon of DEF (AdBlue)
• SCR system warning icon
• Freeze icon of DEF (AdBlue)

C For SCR system inducement display appearing on LCD, refer to measures of the table below. On the SCR system, the remaining amount and quality of DEF (AdBlue) as well as machine troubles are monitored. If anything goes wrong during operation, the following warnings are issued. Follow the warning contents to take proper measures.

A The limited engine output level: The text 'Lv.1' and 'Lv.2' displayed next to the icon represents the limited engine output level. Lv.1 (Level 1): Within 50% of max torque and 60% of engine speed. Lv.2 (Level 2): Within engine near idling speed.
A After an error has occurred, it may be necessary for the engine output to become limited to Lv.2(Level.2). Depending on trouble spots and contents, the indicator-prompted warnings and the engine output limits and timings may vary accordingly. The SCR warning status (from 1 to 3) represents the severity order of the engine output limitation. If the SCR system experiences abnormalities, an error code will be displayed, and it may be necessary to limit the engine output to Idle Status (Lv.2:Level.2). (e.g. When a 'ENG P-204F' error code is displayed, the engine output changes from unrestricted to Lv.2 limited.)
A Points after taking measures. After the engine has stopped and the DEF (AdBlue) has drained, if the amount that was refilled is less than the predrain amount, the SCR system may experience a malfunction ('ENG P-20F5' error code is displayed). When the error occurs, turn the key switch to OFF, wait for the SCR system to complete the purge process (this may take several minutes) and then turn the key switch to ON again in order to clear the SCR system malfunction.
A The time displayed on the icon's lower-right represents the minimum time until the beginning of limitation.
A The 40 hours warning record.
(1) Basically Warning and/or inducement reduction cancel when the fault location is repaired.
(2) However, if it detects any fault within 40 hours of the restoration, it soon becomes back to the previous failure and the timer restarts counting down.
(3) The 40 hours warning record will be reset if any fault has not been detected over 40 hours from the repair. If a fault would be detected after the 40 hours warning record reset, then the new countdown will be stated.

B Adding DEF (AdBlue)

A The DEF tank cap is blue. Do not add DEF (AdBlue) to the fuel tank. Also, do not add diesel fuel to the DEF tank.
A If anything other than DEF (AdBlue) is mixed into the DEF tank and the engine is started, the SCR system may fail. Do not start the engine if the DEF (AdBlue) is contaminated with diesel fuel. Consult your local Kubota Dealer immediately.
A The warranty does not cover failures caused by adding or mixing anything other than DEF (AdBlue) into the DEF tank. If that occurs, all repair costs will be the customer's responsibility.

(1) DEF tank (2) DEF tank cap (Blue)

A Before adding DEF (AdBlue) to the DEF tank, clean the area around the nozzle and supply port to prevent foreign matter such as soil and dust from entering.
A Be sure to turn the key switch to 'OFF' position before adding DEF (AdBlue). After stopping the engine, the SCR system continues to operate for up to about 15 minutes. Do not add DEF (AdBlue) before the SCR system stops. Otherwise, DEF (AdBlue) may overflow from the breather hose of the DEF tank.
A If DEF (AdBlue) is stored in a reusable container, periodically clean and refill it. If the container is dirty, wash with distilled water. If distilled water is not available for washing the container, rinse with clean water first, then rinse again with DEF (AdBlue) before refilling.
A In order to maintain the performance of the SCR system, it is recommended to refill the DEF tank with DEF (AdBlue) each time the fuel tank is refueled.

B Draining DEF (AdBlue)

A Do not run the engine when the DEF tank is empty.
A Remove the drain plug shown in the following illustration, then drain the DEF (AdBlue) into a container.
A Make sure to keep the rubber O-ring of the drain plug clean of oil.
A Do not use a power tool when reinstalling the drain plug. Overtightening the drain plug may cause damage.
Drain plug tightening torque: 4.0 N-m to 6.0 N-m (3.0 lbs-ft to 4.4 lbs-ft) (35.4 lbs-in to 53.1 lbs-in)

(1) Drain plug

A Be sure to turn the key switch to 'OFF' position when draining DEF (AdBlue).
A When draining and refilling the DEF (AdBlue) in the DEF tank, if the refilled amount is less than the drained amount, an SCR system error 'ENG P-20F5' will be displayed on the instrument panel. When the error code 'ENG P-20F5' is displayed, run the engine for 10 minutes in order to clear the SCR system error/warning code. If the error/warning is displayed after running the engine for more than 10 minutes, consult your local Kubota dealer. In order to avoid the aforementioned error, it is recommended that you fully refill the DEF tank every time.
A For the disposal of drained DEF (AdBlue), read the following information. (See 'Disposing of DEF (AdBlue)' in 'SELECTIVE CATALYTIC REDUCTION (SCR) SYSTEM' in 'OPERATING THE ENGINE' section.)

B Storing Purchased DEF (AdBlue)

A Note the following when storing DEF (AdBlue):

• Close the container firmly.
• Avoid direct sunlight.
• Store in a well-ventilated room.
• Store in a place with little temperature change.

A Do not use the following DEF (AdBlue) even if it is still unused. The DEF (AdBlue) may be deteriorated, which may cause SCR system failure.

• When the storage period is unknown.
• When the storage environment is unknown (especially in a high-temperature environment).
• When DEF (AdBlue) has a strong ammonia odor.

A When storing and carrying DEF (AdBlue), use the original container. Otherwise, prepare a dedicated container. For the dedicated container, use a clean polyethylene resin tank (PE) or a stainless steel container free of foreign matter such as water and dust.
A Keep containers used for storing and refilling DEF (AdBlue) free from dirt and dust. Use distilled water to clean the containers. If distilled water is not available for cleaning the containers, rinse with clean water first, then rinse again thoroughly with DEF (AdBlue) before refilling.
A The appropriate environment for storing DEF (AdBlue) is between -5C to 30C (23F to 86F). See the following table for more information about the storage life of DEF (AdBlue). To prevent the shortening of the DEF (AdBlue) storage life, avoid storing the DEF (AdBlue) in environments that exceed 30C (86F).

A The aforementioned storage life is only a guide. Depending on how DEF (AdBlue) is stored, the storage life may be shorter than indicated.
A DEF (AdBlue) freezes when the temperature drops below -11C (12F). The quality of DEF (AdBlue) will not be affected even if frozen. Thaw the DEF (AdBlue) before use.

B Storing DEF (AdBlue) in the DEF Tank

A If the DEF (AdBlue) emits a strong ammonia odor, the quality of the fluid may have deteriorated. To check the quality of the DEF (AdBlue), check the odor of the DEF (AdBlue) in the DEF tank once every 3 months.
A If the DEF (AdBlue) in the DEF tank emits a strong ammonia odor, drain all DEF (AdBlue) from the DEF tank into a container. (See 'Draining DEF (AdBlue)' in 'SELECTIVE CATALYTIC REDUCTION (SCR) SYSTEM' in 'OPERATING THE ENGINE' section.) After draining the DEF (AdBlue), flush the inside of the DEF tank with distilled water. Then refill the DEF tank with new or high-quality DEF (AdBlue).
A When you do not use the machine for more than 3 months, drain all DEF (AdBlue) from the DEF tank. When using the machine after 3 months of inactivity, fully refill the DEF tank with new or high-quality DEF (AdBlue).
A DEF (AdBlue) of deteriorated quality may cause a drop in engine output or an engine malfunction.
A If distilled water is not available for flushing the inside of the DEF tank, rinse with clean water first, then rinse thoroughly with DEF (AdBlue) again. Afterward, replenish with new or high-quality DEF (AdBlue).
A Be sure to turn the key switch to 'OFF' position when replacing the DEF (AdBlue).
A When draining and refilling the DEF (AdBlue) in the DEF tank, if the refilled amount is less than the drained amount, an SCR system error is displayed on the instrument panel, but this is not a malfunction. (See 'Draining DEF (AdBlue)' in 'SELECTIVE CATALYTIC REDUCTION (SCR) SYSTEM' in 'OPERATING THE ENGINE' section.)

B Disposing of DEF (AdBlue)

Although not a hazardous substance, dispose of the used DEF (AdBlue) properly to avoid environmental pollution. For disposal methods, consult your supplier or an industrial waste disposal contractor.

B Handling Precautions after Stopping the Engine

After stopping the engine, the SCR system automatically operates for up to about 15 minutes and returns the DEF (AdBlue) in the piping to the DEF tank to prevent freezing and clogging. The SCR system may generate operating noise after the engine has stopped, but this is not a malfunction. Note the following precautions after stopping the engine:

• A Do not remove the battery terminal until the SCR system stops. This is to prevent damage to the system device.
• A Do not refill with DEF (AdBlue) before the SCR system stops. Otherwise, DEF (AdBlue) may overflow from the breather hose of the DEF tank.

B Precautions when Using in Cold Regions

A DEF (AdBlue) freezes below -11C (12F), but this does not affect the start-up of the engine.
A The DEF (AdBlue) is automatically thawed while the engine is running.
A While thawing, output may be limited to protect the SCR system.
A However, in weather conditions of under -30C (22F), the DEF (AdBlue) cannot be completely thawed and therefore, an error/warning code 'ENG P-208B' appears on the instrument panel. If the error/warning code 'ENG P-208B' appears on the screen, stop the engine and restart it after 10 seconds. After restarting the engine, the error/warning code 'ENG P-208B' will disappear and the thawing of the DEF (AdBlue) will resume. In case the error/warning code 'ENG P-208B' remains on the screen even after restarting the engine several times, consult your local Kubota Dealer.

3. Turn the key to 'START' position and release when the engine starts.

A Because of the safety devices, the engine will not start except when the PTO clutch control switch is placed in the 'OFF' position and shuttle shift lever is placed in the 'NEUTRAL' position.
A If the engine fails to start after 10 seconds, turn off the key for 30 seconds. Then repeat steps 6 through 8. To protect the battery and the starter, make sure that the starter is not continuously turned for more than 10 seconds.

A DEF (AdBlue) freezes at temperatures below -11 (12 ). Even if it is frozen, the engine is not affected at its start-up and running.

B Block Heater (if equipped)

A block heater is available as an option from your dealer. It will assist you in starting your tractor when the ambient temperature is below -20 (-4 ).

B Engine Low Temperature Regulation

In order to prevent engine damage due to rapid acceleration, if starting the engine when coolant temperature is approximately 0C (32F) or below, the engine rpm will be kept at approximately 1400 for up to 3 minutes, and the operator will be informed by indicator and intermittent buzzer. The regulation time varies in response to the coolant temperature. During regulation, perform warm-up operation without using the accelerator. After regulation, the engine rpm can be gradually increased. When regulation has been completely released, the indicator will go off and the buzzer stop.

(1) Low temperature regulation indicator

B DEF (AdBlue) Freeze Warning

When operating in cold weather, the DEF (AdBlue) is automatically thawed while the engine is running. However, in weather conditions of under -30 (-22 ), the DEF (AdBlue) cannot be completely thawed and thus, an error/warning code (ENG P-208B) appears on the instrument panel's LCD screen. If the error/warning code (ENG P-208B) appears on the screen, stop the engine and restart it after 10 seconds. After restarting the engine, the error/warning code (ENG P-208B) will disappear and the thawing of the DEF (AdBlue) will resume. In case the error/warning code (ENG P-208B) remains on the screen even after restarting the engine several times, contact your local KUBOTA Dealer.

STOPPING THE ENGINE

1. After slowing the engine to idle, wait 3 to 5 minutes for turbo to slow down and then turn the key to 'OFF'.
2. Remove the key.

After stopping the engine, the SCR system automatically operates for up to about 15 minutes and returns the DEF (AdBlue) in the piping to the DEF tank to prevent freezing and clogging. The SCR system may generate operating noise after the engine has stopped, but this is not a malfunction. Note the following precautions after stopping the engine:

• A Do not remove the battery terminal until the SCR system stops. This is to prevent damage to the system device.
• A Do not refill with DEF (AdBlue) before the SCR system stops. Otherwise, DEF (AdBlue) may overflow from the breather hose of the DEF tank.

A If key's operation does not stop the engine, consult your local KUBOTA Dealer.

WARMING UP

To avoid personal injury or death:
A Be sure to set the main gear shift lever to 'PARK' position and set the shuttle shift lever to the 'NEUTRAL' position and place the PTO switch in the 'OFF' position during warm-up.

For 5 minutes after engine start-up, allow engine to warm up without applying any load, this is to allow oil to reach every engine part. If load should be applied to the engine without this warm-up period, trouble such as seizure, breakage or premature wear may develop.

B Warm-up and Transmission Oil at Low Temperature Range

Hydraulic oil serves as transmission fluid. In cold weather, the oil may be cold with increased viscosity. This can cause delayed oil circulation or abnormally low hydraulic pressure for some time after engine start-up. This in turn can result in trouble in the hydraulic system. To prevent the above, observe the following instructions: Warm up the engine at about 50 % of rated rpm according to the table below:

A Do not operate the tractor under full load condition until it is sufficiently warmed up.

JUMP STARTING

To avoid personal injury or death:
A Battery gases can explode. Keep cigarettes, sparks, and flames away from battery.
A If tractor battery is frozen, do not jump start engine.
A Do not connect the other end of the negative (-) jumper cable to the negative (-) terminal of the tractor battery.

When jump starting the engine, follow the instructions below to safely start the engine.

1. Bring the helper vehicle with a battery of the same voltage as disabled tractor within easy cable reach. 'THE VEHICLES MUST NOT TOUCH'.
2. Engage the parking brakes of both vehicles and put the shift levers in neutral. Shut both engines off.
3. Wear eye protection and rubber gloves.
4. Attach the red clamp to the positive (red, (+) or pos.) terminal of the dead battery and clamp the other end of the same cable to the positive (red, (+) or pos.) terminal of the helper battery.
5. Clamp the other cable to the negative (black, (-) or neg.) terminal of the helper battery.
6. Clamp the other end to the engine block or frame of the disabled tractor as far from the dead battery as possible.
7. Start the helper vehicle and let its engine run for a few moments. Start the disabled tractor.
8. Disconnect the jumper cables in the exact reverse order of attachment. (Steps 6, 5 and 4)

A This machine has a 12 volt negative (-) ground starting system.
A Use only same voltage for jump starting.
A Use of a higher voltage source on tractor's electrical system could result in severe damage to tractor's electrical system. Use only matching voltage source when 'Jump starting' a low or dead battery condition.
A Do not operate the tractor with the battery cable disconnected from the battery.
A Do not operate the tractor without the battery mounted.
A Do not operate the tractor with the battery dead. Charge the battery fully enough before operating the tractor. Otherwise the tractor might malfunction.

OPERATING THE TRACTOR

OPERATING NEW TRACTOR

How a new tractor is handled and maintained determines the life of the tractor. A new tractor just off the factory production line has been, of course, tested, but the various parts are not accustomed to each other, so care should be taken to operate the tractor for the first 50 hours at a slower speed and avoid excessive work or operation until the various parts become 'broken-in'. The manner in which the tractor is handled during the 'breaking-in' period greatly affects the life of your tractor. Therefore, to obtain the maximum performance and the longest life of the tractor, it is very important to properly break-in your tractor. In handling a new tractor, the following precautions should be observed.

B Do not Operate the Tractor at Full Speed for the First 50 Hours.

A Do not start quickly nor apply the brakes suddenly.
A In winter, operate the tractor after fully warming up the engine.
A Do not run the engine at speeds faster than necessary.
A On rough roads, slow down to suitable speeds. Do not operate the tractor at fast speed. The above precautions are not limited only to new tractors, but to all tractors. But it should be especially observed in the case of new tractors.

B Changing Lubricating Oil for New Tractors

The lubricating oil is especially important in the case of a new tractor. The various parts are not 'broken-in' and are not accustomed to each other; small metal grit may develop during the operation of the tractor; and this may wear out or damage the parts. Therefore, care should be taken to change the lubricating oil a little earlier than would ordinarily be required. For further details of change interval hours. (See 'MAINTENANCE' section.)

BOARDING AND LEAVING THE TRACTOR

1. Never try to get on or off a moving tractor or jump off the tractor to exit.
2. Face the tractor when getting into or out of the tractor. Do not use the controls as hand holds to prevent inadvertent machine movements.
3. Always keep steps and floor clean to avoid slippery conditions.

This indicator serves the following two functions. If the indicator lights up, pinpoint the cause and take a proper measure.
1. Error with the engine control system If during operation the water temperature gauge reads an acceptable level but the warning lamp in the Easy Checker comes on, stop the engine and get it restarted. If the error happens again, consult your local KUBOTA Dealer.
A If the warning indicator lights up, the following phenomena may appear depending on the engine's trouble spot. A The engine stops unexpectedly. A The engine fails to start or gets interrupted just after start. A The engine output is not enough. A The engine output is enough, but the warning indicator stays on. If the engine output is not enough, immediately interrupt the operation and move the tractor to a safe place and stop the engine.
2. Engine overheat If the water temperature gauge reads an unusual level and the warning lamp in the Easy Checker comes on, the engine may have got overheated. Check the tractor by referring to 'TROUBLESHOOTING' section.

Engine oil pressure

If the oil pressure in the engine goes below the prescribed level, the warning lamp in the Easy Checker will come on. If this should happen during operation, and it does not go off when the engine is accelerated to more than 1000 rpm, check level of engine oil. (See 'Checking Engine Oil Level' in 'DAILY CHECK' in 'PERIODIC SERVICE' section.)

SCR system warning

If trouble should occur at the SCR system, the warning indicator in the Easy Checker will light up. If this should happen during operation, check the SCR system or consult your local KUBOTA Dealer.

Fuel level

If the fuel in the tank goes below the prescribed level, the warning lamp in the Easy Checker will come on. (less than 20 L (5.3 gals.)) If this should happen during operation, refuel as soon as possible. (See 'Checking and Refueling' in 'DAILY CHECK' in 'PERIODIC SERVICE' section.)

A When the fuel warning lamp lights up, refuel the tank as soon as possible. If the tractor runs out of fuel and stalls, the engine and its components may be damaged.

ELECTRONIC ENGINE CONTROL

The electronically controlled engine which is installed in this tractor performs the following 2 types of control.

1. RPM dual memory setting
2. Constant RPM management control

B RPM Dual Memory Setting

Two different engine speeds can each be set with a single touch by pressing the RPM dual memory switch to the (A) or (B) side. This can be used to eliminate troublesome acceleration operations.

Work: During work, simply press the switch to the (A) side to automatically set an engine speed of 2000 rpm.
Turning: When turning, press the switch to the (B) side to lower the speed to 1000 rpm, allowing turning at low speed. After turning, press the switch again to the (A) side to resume a speed of 2000 rpm.

(1) RPM dual memory switch (A) Switch A (B) Switch B

C Example of use

Consider an example in which an engine speed of 2000 rpm is set for the switch (A) side and a speed of 1000 rpm is set for the switch (B) side.

A Keep the hand throttle lever above the minimum speed. At the minimum speed, a memory setup can not be performed.
A You can also depress the foot throttle to increase the engine speed above the set speed.

C Setting the speeds (or changing the speed settings)

Setting RPM dual memory switch (A)

1. Turn the key switch to 'ON'. (The speed setting can be made both when the engine is running or stopped.)

(A) Light up.... Engine revolution is operating in the rpm memory setting value.
(A) Flashing.... Engine revolution is less than the rpm memory setting value.

1. Set the hand throttle lever slightly toward the higher-speed side.
2. Press the switch (A) side and then release the switch.
3. Again press and hold down the switch (A) side (2.5 seconds) until the buzzer sounds, then release the switch.
4. Press the switch to the (A) or (B) side and set the speed. Pressing and holding down the switch will cause the speed to change continuously. Pressing and releasing the switch changes the speed by 10 rpm each time. Set the desired engine speed while watching the speed display.
5. If the switch is released and not operated for 4 seconds, a continuous buzzer sound occurs and the setting is completed.
6. Follow the same procedure as for the (A) side to set the speed for the switch (B) side.

A The set speeds will be stored even after the engine is stopped.

C Canceling the setting

Any of the actions below will cancel the RPM dual memory settings.

1. [Switch (A) side]
   When the memory speed is engaged, press the switch (A) again to cancel. [Switch (B) side]
   When the memory speed is engaged, press the switch (B) again to cancel. When the memory speed is canceled, the speed will return to the speed that is determined by the hand throttle lever (foot throttle). (When the switch is pressed, the LCD will display the engine speed that is in effect after memory speed is canceled.)
2. Return the hand throttle lever to the lowest speed position.
3. Turn the key switch to 'OFF'.

B Constant RPM Management Control

Constant RPM Management can be turned 'ON' or 'OFF' by operating the switch. Pressing the switch turns the control 'ON' and pressing the switch again turns it 'OFF'.

• C When constant RPM management is 'ON' Fluctuations in the engine speed due to load fluctuations are reduced and the travel speed and PTO speed are kept nearly constant, allowing stable work. When constant RPM management is 'ON', the switch's indicator light up.
• C When constant RPM management is 'OFF' As in a conventional engine, the engine speed increases or decreases according to changes in the load. The operator judges the size of the load from the engine speed and engine sound, and can adjust the travel speed or plowing depth to prevent overload on the tractor.

(1) Constant RPM management switch with indicator

A The purpose of constant RPM management is not to increase the engine power.
A In a mechanically-controlled engine, the engine speed changes according to increases and decreases in the load. For example, when working in a hilly area, the load increases and engine speed drops while ascending a slope, and conversely the load drops when descending. These changes in engine speed affect the travel speed and PTO-driven implements. In order to minimize these effects, the operator must make fine adjustments to the travel speed and hand throttle lever. When the constant RPM management switch in this tractor with its electronically controlled engine is turned 'ON', the engine speed will be kept nearly constant in response to a certain level of load fluctuations. This improves the accuracy of work without the need for troublesome manipulation of the travel speed and hand throttle lever.
A There is a limit to the range within which a constant speed can be maintained. If a load exceeding the engine performance is applied, the engine speed will drop.

PARKING

B Parking

To avoid personal injury or death:
BEFORE DISMOUNTING TRACTOR
A ALWAYS SET PARKING BRAKE AND LOWER ALL IMPLEMENTS TO THE GROUND.
Leaving transmission in gear with the engine stopped will not prevent the tractor from accidental rolling.
A STOP THE ENGINE AND REMOVE THE KEY.

1. Before getting off the tractor, disengage the PTO, lower all implements, place all control levers in their neutral positions, pull the parking brake lever to parking position, stop the engine and remove the key.
2. If it is necessary to park on an incline, be sure to chock the wheels to prevent accidental rolling of the machine.

(1) Parking brake lever (2) Release button (A) 'PARKING POSITION' (B) 'TRANSPORT POSITION'

A Do not leave your tractor in the rain. If it cannot be avoided, cover the muffler pipe to prevent water entering.

OPERATING TECHNIQUES

B Differential Lock

To avoid personal injury or death due to loss of steering control:
A Do not operate the tractor at high speed with differential lock engaged.
A Do not attempt to turn with the differential lock engaged.
A Be sure to release the differential lock before making a turn in field conditions.

If one of the rear wheels should slip, step on the differential lock pedal. Both wheels will turn together, then reduce slippage. Differential lock is maintained only while the pedal is depressed.

(1) Differential lock pedal (A) Press to 'ENGAGE' (B) Release to 'DISENGAGE'

A When using the differential lock, always slow the engine down.
A To prevent damage to power train, do not engage differential lock when one wheel is spinning and the other is completely stopped.
A If the differential lock cannot be released, step lightly on the brake pedals alternately.

B Operating the Tractor on a Road

To avoid personal injury or death:
A To help assure straight line stops when driving at transport speeds, lock the brake pedals together. Uneven braking at road speeds could cause the tractor to roll-over.
A When traveling on road with 3-point hitch mounted implement attached, be sure to have sufficient front weight on the tractor to maintain steering ability.
A When traveling on road with trailer, you must comply with local regulation at all time. The maximum traveling speed with trailer is provided by each country and regulated speed may be different depend on the size of trailer and type of trailer brake system.

Be sure SMV emblem and warning lamps are clean and visible. If towed or rear-mounted equipment obstructs these safety devices, install SMV emblem and warning lamps on equipment. Consult your local KUBOTA Dealer for further details.

(1) SMV emblem (2) Bracket

B Operating on Slopes and Rough Terrain

To avoid personal injury or death:
A Always back up when going up a steep slope. Driving forward could cause the tractor to tip over backward. Stay off hills and slopes too steep for safe operation.
A Avoid changing gears when climbing or descending a slope.
A If operating on a slope, never disengage the clutch or shift levers to neutral. Doing so could cause loss of control.
A Do not drive the tractor close to the edges of ditches or banks which may collapse under the weight of the tractor. Especially when the ground is loose or wet.

1. Be sure wheel tread is adjusted to provide maximum stability. (See 'WHEEL ADJUSTMENT' in 'TIRES, WHEELS AND BALLAST' section.)
2. Slow down for slopes, rough ground, and sharp turns, especially when transporting heavy, rear mounted equipment.
3. Before descending a slope, shift to a gear low enough to control speed without using brakes.

B Transport the Tractor Safely

1. The tractor, if damaged, must be carried on a truck. Secure the tractor tightly with ropes.
2. Follow the instruction below when towing the tractor: Otherwise, the tractor's powertrain may get damaged.
   A Set the all shift levers to 'NEUTRAL' position.
   A If possible, start engine and select 2WD, if creep speed is fitted ensure that it is disengaged.
   A Tow the tractor using its front hitch or drawbar.
   A Never tow faster than '10 km/h (6.2 mph)'.

B Directions for Use of Power Steering

1. Power steering is activated only while the engine is running. Slow engine speeds make the steering a little heavier. While the engine is stopped, the tractor functions in the same manner as tractors without power steering.
2. When the steering wheel is turned all the way to the stop, the relief valve is activated. Do not hold the steering wheel in this position for a long period of time.
3. Avoid turning the steering wheel while the tractor is stopped, or tires may wear out sooner.
4. The power steering mechanism makes the steering easier. Be careful when driving on a road at high speeds.

B PTO Gear Shift Lever [if equipped]

To avoid personal injury or death:
A Be sure to observe the PTO shaft speed prescribed for the individual implements. It is extremely dangerous to run an implement at high speed that is meant to be operated at low speed. Use only when this higher rpm is specifically recommended by the implement manufacturer.

The PTO gear shift lever can be set to either 540 rpm or 540E rpm positions. Move this lever to either position with the PTO clutch control switch set to 'OFF'.

(1) PTO gear shift lever (A) 540 rpm (B) 540E rpm

A When light load, select the '540E' position for economical operation.

B PTO Speed Limiter

A Move the PTO gear shift lever (if equipped) to '540E' and then turn on the PTO clutch control switch, and the rev-limiter indicator lights up on the meter panel.
A If the PTO clutch control switch is turned on with the engine rpm higher than the PTO 540E limit level, the PTO clutch indicator on the meter panel starts blinking and the PTO is disabled. After a while, the engine rpm automatically drops below the PTO 540E limit level and the PTO starts functioning. At the same time, the flashing PTO clutch indicator stays 'ON'.
A If the PTO clutch control switch is turned 'OFF' but the engine rpm fails to rise with the throttle, return the engine rpm to a lower level. This enables acceleration again.

(1) Rev-limiter indicator (2) PTO clutch indicator

B 1000 rpm PTO Shaft [if equipped]

To avoid personal injury or death:
A Be sure to observe the PTO shaft speed prescribed for the individual implements. It is extremely dangerous to run an implement at high speed that is meant to be operated at low speed. Use only when this higher rpm is specifically recommended by the implement manufacturer.

By interchanging the PTO shafts, 2 different PTO shaft speeds can be obtained.

HYDRAULIC UNIT

The standard tractor has following hydraulic control systems as shown below. Therefore, use the most appropriate system for the implement you are using.

• C 3-Point Hitch Control System
  1. Position Control
  2. Draft Control
  3. Mixed Control
  4. Float Control
• C Remote Hydraulic Control System

A Do not operate until the engine is warmed up. If operation is attempted when the engine is still cold, the hydraulic system may be damaged.
A If noises are heard when implement is lifting after the hydraulic control lever has been activated, the hydraulic mechanism is not adjusted properly. Unless corrected, the unit will be damaged. Contact your KUBOTA Dealer for adjustment.

3-POINT HITCH CONTROL SYSTEM

To avoid personal injury or death:
A Before using the 3-point hitch controls, ensure that no person or object is in the area of the implement or 3-point hitch. Do not stand on or near the implement or between the implement and tractor when operating the 3-point hitch controls.

B Position Control

This will control the working depth of 3-point hitch mounted implement regardless of the amount of pull required.

(1) Position control lever (2) Draft control lever (A) 'FLOAT' (B) 'DOWN' (C) 'UP'

B Draft Control

This will control the pull of the 3-point implement. As the load on the 3-point hitch changes due to various soil conditions, the draft control system automatically responds to these changes by either raising or lowering the implement slightly to maintain a constant pull. Place the position control lever in the lowest position and set the implement pull with the draft control lever.

(1) Draft control lever (2) Position control lever (A) 'SENSITIVE' (B) 'INSENSITIVE' (C) 'FLOAT'

B Mixed Control

In draft control, when draft decreases, the implement automatically lowers to increase draft. However, the implement sometimes lowers too much. To limit the degree, the implement can be lowered, set the position control lever at the lowest working depth desired for the implement. Lower the draft control lever to the point where the implement is at the desired depth. This stops the implement from going too deep and causing loss of traction and ground speed.

(1) Ground surface (2) Implement penetration limit (3) Light soil

B Float Control

Place both the draft control lever and the position control lever in the float position to make the lower links move freely along with the ground conditions.

B 3-point Hitch Lowering Speed

To avoid personal injury or death:
A Fast lowering speed may cause damage or injury. Lowering speed of implement should be adjusted to 2 or more seconds. The lowering speed of the 3-point hitch can be controlled by adjusting the 3-point hitch lowering speed knob.

(1) 3-point hitch lowering speed knob (A) 'FAST' (B) 'SLOW' (C) 'LOCK'

REMOTE HYDRAULIC CONTROL SYSTEM

The hydraulic auxiliary control valves can be installed up to triple segments.

B Remote Control Valve

There are 2 types of remote valves available for these models. A Double acting valve with detents and self cancelling: This valve may be placed in the detent mode. The lever will stay in this position until the pressure reaches a predetermined level or a cylinder reaches the end of its stroke. Then it will automatically return to neutral. A Double acting valve with float position: This valve may be placed in the float mode with the control lever all the way forward. The cylinder is free to extend or retract, letting an implement such as a loader bucket follow the ground.

B Remote Control Valve Lever

The remote control valve lever directs pressurized oil flow to the implement hydraulic system. [Example: Installing triple segment valves]

1st: Double acting valve with detents and self cancelling (standard)
2nd: Double acting valve with float position (option)
3rd: Double acting valve with detents and self cancelling (option)

Lever (1) Z (detent) [A] out Port [B] in Pressure Returning Lever position Y X Z (detent)
Lever (2) [C] Port [D] Lever position Z (detent)
Lever (3) Z (detent) [E] out Port [F] in Lever position Y X Z (detent)

(1) Remote control valve lever 1 (2) Remote control valve lever 2 (3) Remote control valve lever 3

A Do not hold the lever in the 'pull' or 'push' position once the remote cylinder has reached the end of the stroke, as this will cause oil to flow through the relief valve. Forcing oil through the relief valve for extended periods will overheat the oil.
A When using the tractor hydraulic system to power front loader, do not operate boom and bucket cylinders simultaneously.
A Connect the pressure of load side of implement cylinders to ports [B], [D] or [F] which have built in load check valve to prevent leak down.

B Remote Control Valve Coupler Connecting and Disconnecting

To avoid personal injury or death:
A Stop the engine and relieve pressure before connecting or disconnecting lines.
A Do not use your hand to check for leaks.

C Connecting

1. Clean both couplers.
2. Remove dust plugs.
3. Insert the implement coupler to the tractor hydraulic coupler.
4. Pull the implement coupler slightly to make sure couplers are firmly connected.

C Disconnecting

1. Lower the implement first to the ground to release hydraulic pressure in the hoses.
2. Clean the couplers.
3. Relieve pressure by moving hydraulic control levers with engine shut off. Pull the hose straight from the hydraulic coupler to release it.
4. Clean oil and dust from the coupler, then replace the dust plugs.

A Your local KUBOTA Dealer can supply parts to adapt couplers to hydraulic hoses.

B Flow Control Valve (option)

The optional flow control valve may be added for the following purposes.

1. To operate within limits, the remote control valve (2) above the flow control valve (3) and the 3-point hitch at the same time without one affecting the other.
2. To operate within limits, the remote control valve (2) above the flow control valve (3) and the other remote control valve (1) at the same time without one affecting the other. Activating the remote control valve (1) will interrupt the operation of the 3-point hitch.
3. To maintain within limits, the constant speed of an attachment (hydraulic motor RPM, for example) when connected to the remote control valve (2) above the flow control valve (3).

A At slower engine speeds the total hydraulic flow rate may be inadequate for simultaneous operation of the remote control valve (2) and the 3-point hitch or the remote control valve (1), or operation of an attachment connected to the remote control valves (1)(2). Under these conditions, the engine speed must be increased to provide additional hydraulic flow.

B Adjusting the flow rate

To avoid the possibility of personal injury or death be aware of the following when making adjustments:
A The 3-point hitch operation is influenced by the combination of the adjustment of the flow control valve and the engine speed.
A The 3-point hitch may rise slowly or not at all at low engine rpm.
A The 3-point hitch may rise suddenly if engine rpm is increased, or, flow control adjustment is changed.

Refer to the illustration below.

1. The flow rate for the remote control valve (2), located on above the flow control valve (3), can be adjusted.
2. Turn the flow control knob (4) counterclockwise (A), and the flow rate for the remote control valve (2) increases. A clockwise turn (B) of the knob causes the flow to decrease. If the knob is turned all the way (C), there will be no flow.
3. To adjust the flow rate, set the engine speed to the operating RPM, turn the flow control knob once all the way clockwise (C), and then turn it gradually counterclockwise until a required flow rate is reached.

(1) Remote control valve (1) (2) Remote control valve (2) (3) Flow control valve (4) Flow control knob (A) 'INCREASE' (B) 'DECREASE' (C) 'STOP'

A Full adjustment of the valve will occur in approximately 1 1/2 revolutions of the flow control knob. Turning the flow control knob beyond this point will have no affect on the flow rate.
A When there is no need to adjust the flow rate, turn the flow control knob all the way counterclockwise and keep it in this position.

C Positions and advantages of the flow control valve

Refer to illustration below.

C Position 1

1. The attachment control speed (hydraulic motor RPM, for example) of the remote control valve (1) can be maintained at a constant level within limits.
2. The remote control valve (1) and the 3-point hitch can be operated at the same time. The 3-point lift speed will be influenced by the level of flow required at remote control valve (1).

(1) Remote control valve (1) (2) Remote control valve (2) (3) Flow control valve

C Position 2

1. The attachment control speed (hydraulic motor RPM, for example) of the remote control valve (2) can be maintained at a constant level.
2. The remote control valve (2) and the 3-point hitch can be operated at the same time with the speed of the 3point being influenced by the adjustment range of the flow control valve.
3. Remote control valves (1) and (2) can be operated at the same time with operation of the 3-point hitch being interrupted by activation of valve (1).
4. The operation of valve (1) is influenced by the flow adjustment to valve (2).
5. The 3-point hitch lift speed and the flow available for valve (1) are influenced by the flow adjustment of valve (2).
