MechMaxx EFS 48/60/65 Flail Mower

Checking Before Operating

Only use a universal joint conforming to CE standard and protect it properly. Before operating, check the following:

1. Lubricate all grease points and lubricated parts inside the machine.
2. Use an agricultural tractor within the specified horsepower limits.
3. Ensure the machine is properly attached to the tractor with retainers on the mounting pins.
4. Confirm extra weights are mounted on the front of the tractor if required.
5. Check the gearbox oil level and add as required.
6. Verify the tractor PTO shaft turns freely and the machine driving shaft telescopes easily.
7. Inspect blades for damage or breakage, and ensure they swing freely. Repair or replace as needed.
8. Check and tighten blade bolts.
9. Remove any entangled material from rotating parts.
10. Install and secure all guards, doors, and covers before starting.
11. Before installing the universal joint, stop the tractor and machine motor, and remove the key. Ensure universal joints are in good state with proper protective parts.
12. Check the chain on the universal joint protective parts for good condition to prevent automatic rotation.
13. Ensure all other persons leave the ground area before connecting the tractor's driving power. Keep the tractor output at 540 RPM.
14. Before cleaning, repairing, or lubricating, stop the motor and take the key.
15. When the universal joint is not connected, secure it to the frame to prevent damage.
16. Do not approach the machine while it is running.

Adjusting the Height

To maximize performance, save fuel and power, and reduce wear, set the cutting height correctly. To adjust the working height:

1. Loosen screw (1) and remove screw (2) on both sides.
2. Adjust the roller height by aligning the selected hole in the roller support bracket. The lowest hole provides the highest working height.
3. Reinsert screw (2) into the selected hole and tighten screws (1) and (2).

An illustration shows the adjustment points (1 and 2) for the roller height.

Flail Mower Adjustment

1. Attach the Flail Mower to the tractor using the three-point linkage on a flat piece of ground.
2. Use a solid adjustable top link.
3. Lower the three-point linkage to its lowest position.
4. With the roller at the rear in contact with the ground, adjust the top link length so the lower edge of the flail mower side is parallel with the ground.
5. Rotate the blade drum by hand to ensure a row of blades hangs vertically towards the ground.
6. Measure the clearance between the bottom of the extended blades and the ground. The minimum clearance should be 50mm.

Note: In rough or lumpy paddocks, increase the clearance to prevent blades from impacting the ground during operation.

7. Adjust the roller height to increase or decrease blade clearance as required.
8. Repeat steps 4 to 7 until the required clearance is achieved.
9. Operate the Flail Mower in low range with the PTO delivering 540 RPM.

Regulating the Tension of Driving Belt

⚠ The machine shall always stand still for regulating the tension.

Remove the driving belt cover.

1. Adjust the drive belt tension. Correct tension is achieved when the belt deflects by its thickness (approx. 10mm) at the center point between the pulleys.
2. Align the gearbox so the drive shaft is parallel with the body.
3. Use a straight edge to ensure belt pulleys are in line and running true. Contact your dealer or service agent for technical support if misaligned.

An illustration shows the belt tensioning mechanism.

Starting Up

Before starting the machine, check and adjust the following:

• Tension of trapezoidal driving belt.
• Oil level of gear.
• Points of lubrication.
• All bolts, nuts, and screws.

⚠ When transferring the machine from a moving state to a working state, do not stand between the machine and the tractor.

The machine coupling is equipped with 3 pins for connection to tractors with universal coupling. Telescopic poles adjust to the tractor type. Keep the Flail mower a safe distance from the tractor. The universal joint should be tense, with the largest distance in the closed state being 2/4 inches.

To connect the 3-point hitch: Move the lifting arm, insert joint pins, and fix them with pins. Secure the lifting arm with a chain and tensioning device to prevent lateral movement. Connect the universal joint to the tractor's PTO shaft. Ensure no collision occurs in any position. Keep the tractor's PTO shaft parallel to the ground. It is crucial to keep the machine's driving axle and the tractor's PTO shaft parallel.

The machine shall be lifted from the ground before moving.

Fluids and Lubricants

1. Grease: Use multi-purpose lithium-based grease.
2. Gear Box Oil: Use N46 drive & hydraulic dual-purpose oil or equivalent. Gearbox Capacity: 0.85 liter.
3. Storing Lubricants: Use clean containers and store in an area protected from dust, moisture, and contaminants for optimal efficiency.

Greasing

• Use a hand-held grease gun for all greasing.
• Wipe grease nipples with a clean cloth before greasing to prevent dirt ingress.
• Replace or repair broken nipples immediately.
• If nipples are blocked, remove and clean thoroughly, including the lubricant passageway. Replace nipple if necessary.

Maintenance

⚠ All maintenance, repairing, cleaning, and lubricating shall be conducted when the tractor and motor are stopped and the key is taken away.

Following a careful service and maintenance program will ensure many years of trouble-free operation. Recommended periods are based on normal operating conditions; severe conditions may require more frequent maintenance.

Storage

Clean the machine inside and out to prevent corrosion. Avoid spraying water on rolling bearings with a high-pressure sprayer. Check and clean the universal joint and drive belt press roller, replacing them if not in good condition. Apply oil to all required parts. Coat rubbed and damaged parts for anti-corrosion. Store the machine in a dry, level area, supporting the frame with planks if necessary.

Operation After Storage

Before starting the machine after storage, check the following:

• Oil level (add if not enough).
• Tightness of all screws and nuts.
• Machine regulated state.
• Blade state.
• Gearbox air hole (clean if blocked).
• Do not spread oil or grease on drive belts; wipe belts if contaminated to prevent sliding and wear.
• Check the machine every 10 hours. Repair damaged parts or replace blades as recommended to maintain balance.
• Check all tightening parts and replace if necessary.
• Do not remove protective parts; protect the machine.

In case of vibration, stop the machine and check the blade. If the blade is broken or damaged, replace it with the same type. If vibration persists, send the machine to an authorized repairer.

Lubrication

Gearbox

Type of Lubrication: SAE 90W Gear Lube

Check oil level in the gearbox by removing the plug on the right-hand side. Oil should be level with the bottom of the plug hole. Add oil if necessary by removing the top fill plug and side plug. Add oil until it flows from the side plug hole. Do not overfill!

An illustration shows the gearbox with oil level check and fill points.

IMPORTANT: Mower should be level when checking oil in the gearbox!
