SEASONAL CLUTCH MAINTENANCE

It is important that the clutches slip when an obstacle or load heavier than the clutch setting is encountered.

Therefore, if the machine sits outside longer than 30 days and is exposed to rain and/or humid air it is

important to make sure that the clutch lining plates are not rusted/coroded together. Before using the cutter use

the following procedure to make sure the clutch will slip and give the overload protection required.

1. Loosen nuts on springs until the springs are free, yet remain secure on bolts. Mnt-R-0272.

2. Attach cutter to tractor and start the tractor. Set the engine speed at 1200 RPM.

3. Mark outer plates as shown in Mnt-R-0272.

4. Engage the PTO (approximately one second) and then quickly disengage it. The friction lining plates

should break loose (check the mark).

5. Turn tractor off. Tighten the nuts on the disc spring clutch until they bottom out, then loosen each nut 2

turns.

BLADE SERVICING

Inspect blades before each use to determine that they are properly installed and in good condition. Replace

any blade that is bent, excessively nicked, worn, or has any other damage. Small nicks can be ground out

when sharpening.

Use only original equipment blades on this cutter. They are made of special heat-treated alloy steel. Substitute

blades may not meet specifications and may fail in a hazardous manner that could cause injury.

BLADE SHARPENING

Always sharpen both blades at same time to maintain balance. Follow original sharpening pattern as shown in

Figure Mnt-R-0008 Always sharpen blades by grinding. DO NOT heat and pound out edge. Do not sharpen

blade to a razor edge, but leave a 1/16" blunt edge. Do not sharpen back side of blade. Mnt-R-0273.

Avoid personal injury. Always block the cutter up to prevent if from falling when the blades

and/or carrier are being serviced.

When sharpening blades, grind each end the same amount to maintain balance.

Unbalanced blades will cause excessive vibration which can damage blade spindle

bearings. Vibration may also cause structural cracks in mower housing.
