1. Move the throttle to the FAST position.
2. Pull the PTO (Blade Engage) Switch outward into the engaged (ON) position. See H in Figure 24 on page 15. NOTE: When operating the tractor be certain that the throttle is always in the FAST position. Operating with the throttle at less than full throttle may lead to premature battery wear and a poor quality cut.
3. To disengage the PTO (Blade Engage), push the PTO (Blade Engage) Switch inward to the disengaged (OFF) position.

Engaging the PTO (Blade Engage)(Manual PTO tractors)

Engaging the PTO (Blade Engage) transfers power to the cutting deck. To engage the PTO:

1. Move the throttle to the FAST position.
2. Push the PTO (Blade Engage) Lever forward into the engaged (ON) position. See Figure 28.

Figure 28: Illustration of the PTO (Blade Engage) Lever.

NOTE: When operating the tractor be certain that the throttle is always in the FAST position. Operating with the throttle at less than full throttle may lead to premature battery wear and a poor quality cut.

3. To disengage the PTO (Blade Engage), push the PTO (Blade Engage) Lever forward and to the right, out of the locked position, then release the lever into the disengaged (OFF) position.

Mowing

WARNING: To help avoid blade contact or a thrown object injury, keep bystanders, helpers, children, and pets at least 75 feet (23 meters) from the machine while it is in operation. Stop machine if anyone enters the area.

WARNING: Make certain the area to be mowed is free of debris, sticks, stones, wire, or other objects that can be thrown by the rotating blades.

NOTE: Do not engage the mower deck when lowered in grass. Premature wear and possible failure of the "V" belt and PTO clutch will result. Fully raise the deck or move to a non-grassy area before engaging the mower deck.

• Mow up and down slopes, not across. If mowing a slope, start at bottom and work upward to ensure turns are made uphill.
• Do not mow at high ground speed, especially if a mulch kit or grass collector is installed.
• Do not cut the grass too short. Short grass is prone to weed growth and yellows quickly in dry weather.
• Always operate the tractor with the throttle in the FAST position while mowing.
• On the first pass, pick a point on the opposite side of the area to be mowed. Follow the point to maintain a straight line.
• Engage the PTO and move the throttle control or throttle/choke control to the FAST position.
• Lower the mower deck to the desired height setting.
• For best results it is recommended that the first two laps be cut with the discharge thrown towards the center. After the first two laps, reverse the direction to throw the discharge to the outside for the balance of cutting. This will give a better appearance to the lawn.

NOTE: The speed of the tractor will affect the quality of the tractor cut. Mowing at full speed will adversely affect the cut quality.

Your tractor is designed to cut normal residential grass of a height no more than 10" (25 cm). Do not attempt to mow through unusually tall, dry grass (e.g., pasture) or piles of dry leaves. Dry grass or leaves may contact the engine exhaust and/or build up on the tractor.

Do NOT attempt to mow heavy brush and weeds or extremely tall grass. Your tractor is designed to mow lawns, NOT clear brush.

• Keep the blades sharp and replace the blades when worn.
• When approaching the other end of the strip, slow down or stop before turning. A three point turn is recommended.
• Align the tractor with an edge of the mowed strip and overlap approximately 3" (7.6 cm).
• Direct the tractor on each subsequent strip to align with a previously cut strip.
• To prevent rutting or grooving of the turf, if possible, change the direction that the strips are mowed by approximately 45° for the next and each subsequent mowing.

When stopping the tractor for any reason while on a grass surface, always:

• Engage the park brake.
• Shut engine off and remove the ignition key.

Doing so will minimize the possibility of having your lawn "browned" by hot exhaust from your tractor's running engine.

Using the Differential Lock (If equipped)

WARNING: When the differential lock is on, be sure to allow for a larger turning radius and greater steering effort. Engage the differential lock only when the vehicle is stationary. Do not use the differential lock when traveling downhill.

With or without the differential lock engaged, all Safe Operation Practices described in this manual must be followed.

NOTE: The system should only be used when poor traction is encountered. It should be disengaged when traveling on solid surfaces.

In some instances, the tractor may be driven in slippery or low-traction situations and it may be necessary to activate the differential lock. To use the differential lock proceed as follows:

1. Stop the motion of the tractor.
2. Depress the differential lock pedal to engage the differential lock. NOTE: The differential lock only works while the pedal is depressed. NOTE: Engagement may be delayed. The differential lock will engage when different wheel speeds are detected.
3. To disengage the differential lock, release the pedal. NOTE: Disengagement may be delayed. The differential lock will disengage when the rear wheel speeds allow it to release.

SERVICE AND MAINTENANCE

WARNING: Before performing any type of maintenance/service, disengage all controls and stop the engine. Wait until all moving parts have come to a complete stop. Allow the engine to cool. Disconnect spark plug wire and ground it against the engine to prevent unintended starting. Always wear safety glasses during operation or while performing any adjustments or repairs.

Follow the Maintenance Schedule given below. This chart describes service guidelines only. Refer to the Engine Operator's Manual for engine maintenance items listed in the table below.

#-- Perform more often in dry conditions and when mulching.

* -- Have this item performed by an authorized service dealer.

NOTE: This Operator's Manual covers several models. Tractor features may vary by model. Not all features in this manual are applicable to all tractor models and the tractor depicted may differ from yours.

Post-Operation Tractor Care

After each operation of the tractor, the following procedures should be implemented to extend the life of your tractor and ensure safe operating conditions.

WARNING: Failure to follow these recommendations may result in serious injury to yourself or others and may cause damage to the tractor.

Cleaning the Underside of the Deck

DECK WASH SYSTEM (IF EQUIPPED): Your tractor's deck may be equipped with a water port on its surface as part of its deck wash system. Use the deck wash system to rinse grass clippings from the deck's underside and prevent the buildup of corrosive chemicals. Complete the following steps AFTER EACH MOWING:

1. Attach the nozzle adapter to a standard garden hose connected to a water supply.
2. Move the tractor to an area within reach of the hose where the dispersal of wet grass clippings is acceptable. Disengage the PTO, engage the park brake and stop the engine.
3. Pull back the lock collar (a) of the nozzle adapter (b) and push the nozzle adapter onto the deck wash nozzle (c). Release the lock collar to lock the nozzle adapter on the deck wash nozzle. See Figure 29.

Figure 29: Illustration of the deck wash system nozzle connection.

4. Turn on the water supply.
5. From the tractor operator's seat, start the engine and engage the PTO. Allow to run as needed. Disengage the PTO and stop the engine.
6. Turn off the water supply.
7. Pull back the lock collar of the nozzle adapter to disconnect the nozzle adapter from the deck wash nozzle.

Cleaning the Tractor

WARNING: If the tractor has been recently run, the engine, muffler, and surrounding metal surfaces will be hot and can cause burns to the skin. Let the engine cool for at least five minutes. Exercise caution to avoid burns.

Your tractor should be cleaned after each use and under certain conditions, i.e. dry conditions and/or mulching situations, additional cleaning may be necessary. One of the best ways to keep your tractor running efficiently and to reduce fire risk is to regularly remove debris buildup from the tractor. Follow the recommendations below and contact your authorized dealer with any questions.

• Allow the tractor to cool at least five minutes in an open area before cleaning.
• Debris can accumulate anywhere on the tractor, especially on horizontal surfaces. Additional cleaning may be necessary when mowing in dry conditions or when mulching.
• Fuel leaks/spills, oil leaks/spills and excess lubrication can also become collection sites for debris. Immediate repair and cleaning up oil or fuel spills can help reduce fire hazards.
• In addition to cleaning the tractor before operating and storing, do not attempt to mow unusually tall grass, 10" (25 cm) or higher, dry grass (e.g., pasture) or piles of dry leaves. Dry grass or leaves may contact the engine exhaust and/or build up on the tractor deck presenting a potential fire hazard.

Storing the Tractor

• Allow the tractor to cool at least five minutes in an open area before storing.
• Do not park the tractor near any flammable materials (wood, cloth or chemicals) or any open flames or other potential source of ignition (furnace, water heater or any other type of heater).
• Remove all combustible materials from the tractor before storing. Empty cargo boxes, grass catchers or containers.
• Always shut off fuel flow when storing or transporting if tractor is equipped with a fuel shutoff.
• Check the fuel system (lines, tank, cap and fittings) frequently for cracks or leaks. Repair and clean as necessary.
• NOTE: If the tractor is temporarily left outside, tip the seat forward and cover it with a suitable plastic bag to prevent rain damage.

Maintenance

ENGINE

WARNING: Allow machine to cool in an open area for at least five minutes before storing or refueling.

Refer to the Engine Operator's Manual for all engine issues and questions.

NOTE: Maintenance, repair or replacement of the emission control devices and systems which are being done at owner's expense may be performed by any engine repair establishment or individual. Warranty repairs must be performed by an authorized dealer.

CHANGING THE ENGINE OIL

WARNING: If the tractor has been recently run, the engine, muffler and surrounding metal surfaces will be hot and can cause burns to the skin. Let the engine cool for at least five minutes. Exercise caution to avoid burns.

NOTE: The oil filter should be changed at every oil change interval.

To complete an oil change, proceed as follows:

1. Run the engine for a short time to warm the engine oil. The oil will flow more freely and carry away more impurities. Use care to avoid burns from hot oil.
2. Open the tractor's hood and locate the oil drain port on the side of the engine.
3. Place an appropriate oil collection container with at least a 2.5 quart (2.36 L) capacity below the opening of the oil drain tube, to collect the used oil. Remove the oil fill cap/dipstick from the oil fill tube.
4. Open the protective cap on the end of the oil drain valve to expose the drain port. See Figure 33.

Figure 33: Illustration of the oil drain valve and port.

5. Push the oil drain tube (packed with this manual) onto the oil drain port. Route the opposite end of the tube into an appropriate oil collection container with at least a 2.5 quart (2.36 L) capacity to collect the used oil.
6. The engine is equipped with a twist-and-pull drain port. Turn the oil drain valve 1/4-turn counter-clockwise, then pull outward to begin draining oil. After the oil has finished draining, push the end of the oil drain valve back in and turn 1/4-turn clockwise to close the oil drain. Re-cap the end of the oil drain valve to keep debris from entering the drain port.
7. Replace the oil filter, and refill the engine with new oil as instructed in the Engine Operator's Manual.
8. Reinstall the oil fill cap/dipstick.

NOTE: Place an absorbent towel beneath the oil filter to keep oil off the engine pulley.

NOTE: Observe proper disposal laws and regulations for gas, oil, etc. to protect the environment.

NOTE: Maintenance, repair or replacement of the emission control devices and systems which are being done at the owner's expense may be performed by any engine repair establishment or individual. Warranty repairs must be performed by an authorized dealer.

Lubrication

WARNING: Before lubricating, repairing, or inspecting, always disengage PTO, set park brake, stop engine, and remove key to prevent unintended starting.

Using a quality lubricating oil, lubricate all lubrication points. Refer to Maintenance Schedule chart located in this manual for proper service intervals.

LUBRICATING FRONT WHEELS

Each of the front wheel axles is equipped with a grease fitting. See Figure 34. Some models have rims equipped with grease fittings (excludes Turf Master and Multi-Trac wheels). See Figure 35. Lubricate with a No. 2 multi-purpose grease applied with a grease gun per the Maintenance Schedule.

Figure 34: Illustration of front wheel grease fitting.

Figure 35: Illustration of rim grease fitting.

LUBRICATING PIVOT POINTS & LINKAGE

Lubricate all the pivot points on the drive system, park brake and lift linkage per the Maintenance Schedule.

NOTE: It is not necessary to grease the steering pinion/sector gear interface. Doing so will allow dirt to accumulate and can affect steering performance.

Hydrostatic Transmission

The hydrostatic transmission is sealed at the factory and is maintenance-free. The fluid level cannot be checked and the fluid cannot be changed.

SERVICE AND MAINTENANCE (Continued)

Spark Arrestor Maintenance (If equipped)

Spark arrestor assemblies must be inspected and cleaned periodically (see the Maintenance Schedule chart in this manual). Visually inspect the screen for tears, broken wires or loose welds. Replace the spark arrestor assembly if any of these conditions exist. If the screen is in good condition, clean the screen by brushing away loose dirt or carbon particles.

Tires

Keep the tires inflated to the recommended pressures. Improper inflation will shorten the tire service life. See the tire side wall for proper inflation pressures. Refer to the Maintenance Schedule chart located in this manual for proper service intervals.

Observe the following guidelines:

• Do not inflate a tire above the maximum pressure shown on the sidewall of the tire.
• Do not reinflate a tire that has been run flat or seriously under-inflated. Have it inspected and serviced by a qualified tire mechanic.

Off-Season Storage

If your tractor is not going to be operated for an extended period of time (30 days to approximately six months), the tractor should be prepared for storage. Store the tractor in a dry and protected location. If stored outside, cover the tractor (including the tires) to protect it from the elements. The procedures outlined below should be performed whenever the tractor is placed in storage.

1. Change the engine oil and filter following the instructions provided in this manual as well as the Engine Operator's Manual provided with this tractor.

WARNING: Never store the tractor with fuel in the tank indoors or in poorly ventilated enclosures, where fuel fumes may reach an open flame, spark, or pilot light as on a furnace, water heater, clothes dryer, etc.

2. If storing the tractor for 30 days or more:

• a. To prevent gum deposits from forming inside the engine's carburetor and causing possible malfunction of the engine, the fuel system must be either completely emptied, or the gasoline must be treated with a stabilizer to prevent deterioration.
• b. Using a fuel stabilizer for storage between 30 and 90 days: Read the product manufacturer's instructions and recommendations. Add to clean, fresh gasoline the correct amount of stabilizer for the capacity (approximately 3 gallons) of the fuel system. Fill the fuel tank with treated fuel and run the engine for 2-3 minutes to get stabilized fuel into the carburetor.
• Fuel left in the fuel tank deteriorates and will cause serious starting problems.
• c. Emptying the fuel system for storage of more than 90 days: Prior to putting the tractor in storage, monitor fuel consumption with the goal of running the fuel tank empty. Run the engine until it begins to stall. Use the choke to keep the engine running until all fuel in the carburetor has been exhausted. Referring to the Engine Operator's Manual, drain the fuel from the carburetor bowl.

3. Clean the engine and the entire tractor thoroughly. NOTE: Using a pressure washer or garden hose is not recommended for cleaning your tractor other than to clean the underside of the deck. It may cause damage to electrical components, spindles, pulleys, bearings or the engine. The use of water will result in shortened life and reduce serviceability.

4. Fully charge the battery, then disconnect the negative cable at the battery to prevent possible discharge. Recharge the battery periodically when in storage. NOTE: Remove the battery if exposed to prolonged periods of sub-freezing temperatures. Store in a cool, dry location where temperatures are above freezing.

5. Lubricate all lubrication points.

Removing the Tractor from Storage

1. Check the engine oil.
2. Fully charge the battery and inflate the tires to the recommended pressure. See tire side wall for proper tire inflation pressure.
3. Fill the fuel tank with clean, fresh gasoline.
4. Start the engine and allow to idle for a few minutes to ensure engine is operating properly.
5. Drive the tractor without a load to make certain all the tractor systems are functioning properly.

Adjustments

DECK LEVELING

If the cutting deck appears to be mowing unevenly, leveling adjustments can be performed.

WARNING: If the tractor has been recently run, the engine, muffler, and surrounding metal surfaces will be very hot and can cause burns to the skin. Let the engine cool for at least five minutes. Exercise caution to avoid burns.

NOTE: Check the tractor's tire pressure before performing any deck leveling adjustments. Refer to Tires in this section for information regarding tire pressure.

LEVELING THE DECK (SIDE-TO-SIDE)

1. With the tractor parked on a firm, level surface, place the deck lift lever in the middle position and rotate both blades so that they are perpendicular with the tractor.
2. Measure the distance from the outside of the left blade tip to the ground and the distance from the outside of the right blade tip to the ground. Both measurements taken should be equal. If they are not, proceed to the next step.
3. Under the rear fenders inside the wheels there is a lift adjustment rod for each side of the deck. See Figure 36.

Figure 36: Illustration of deck lift adjustment rods.

4. Minor side-to-side adjustments should be made using primarily the left adjustment rod.
5. To raise the left side of the deck, loosen the upper nut on the end of the lift rod, then turn the lower nut clockwise. When the proper adjustment is achieved, tighten the upper nut to secure in place. To lower the left side of the deck, loosen the upper nut on the end of the lift rod, then turn the lower nut counter-clockwise. When the proper adjustment is achieved, tighten the upper nut to 25-30 ft-lbs (33.9-40.7 N-m) to secure in place.
6. The deck is properly leveled when both blade tip measurements taken earlier are equal.

LEVELING THE DECK (PITCH/FRONT-TO-REAR)

The front of the deck is supported by a stabilizer bar that can be adjusted to level the deck from front to rear. The front of the deck should be 1/4"-3/8" (6.35 mm-9.5 mm) lower than the rear of the deck. Adjust if necessary as follows:

1. Park the tractor on a firm, level surface, place the deck lift lever in the middle position and rotate the blade nearest the discharge chute so that it is parallel with the tractor.
2. Measure the distance from the front of the blade tip to the ground and the rear of the blade tip to the ground. The front of the deck should be between 1/4"-3/8"(6.35 mm-9.5 mm) less than the rear of deck.
3. Determine the approximate distance necessary for proper adjustment and proceed, if necessary.
4. To raise the front of the deck, loosen the outer nut then tighten (thread inward) the inner nut against the front hanger bracket. See Figure 37. When proper adjustment is achieved, re-tighten the outer nut to 25-30 ft-lbs (34 mm-40.7 N-m).

Figure 37: Illustration of front hanger bracket adjustment.

5. To lower the front of the deck, loosen the outer nut then loosen (thread outward) the inner nut, away from the front hanger bracket. See Figure 37. When proper adjustment is achieved, re-tighten the outer nut.

Adjusting the Deck Wheels

WARNING: Keep hands and feet away from the discharge opening of the cutting deck.

NOTE: The deck wheels are an anti-scalp feature of the deck and are not designed to support the weight of the deck.

The deck wheels should be approximately 1/4"-1/2" (6.35 mm-12.7 mm) above the ground when the deck is set in the desired height setting. To adjust the deck wheels see the Assembly section for instructions.

Service

ELECTRICAL SYSTEM

A fuse is installed to protect the tractor's electrical system from damage caused by excessive amperage. Always use the same capacity fuse for replacement. If the electrical system does not function, check for a blown fuse.

If you have a recurring problem with blown fuses, have the tractor's electrical system checked by your authorized service dealer.

RELAYS AND SWITCHES

There are several safety switches in the electrical system. If a function of the safety interlock system described earlier is not functioning properly, have the electrical system checked by your authorized service dealer.

SERVICE AND MAINTENANCE (Continued)

PARK BRAKE ADJUSTMENT

If the tractor does not come to a complete stop when the brake pedal is completely depressed, or if the tractor's rear wheels can roll with the park brake applied (and the hydrostatic relief valve open), the brake is in need of adjustment. See your authorized service dealer to have the brake adjusted.

HYDROSTATIC NEUTRAL ADJUSTMENT

If the tractor creeps forward or rearward when neither the forward nor reverse pedal is depressed, contact your local authorized dealer to have the neutral setting properly adjusted.
