Coil Spring Slip Clutch

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/corroded 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 (Figure Mnt-R-0353)on springs until the springs are free, yet remain secure on bolts.

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

3.Mark outer plates as shown in Figure Mnt-R-0353

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 coil spring clutch to their original position of 1-5/16” compressed spring length.
