Slip-Clutch Protected Drivelines

Cutter drive components are protected from shock loads
by a friction slip-clutch. The clutch must be capable of
slippage during operation to protect the gearbox,
driveline and other drive train parts.

Clutch Run-In

Friction clutches should be "run-in" prior to initial
operation and after long periods of inactivity to remove
any oxidation that may have accumulated on friction
surfaces. To prevent driveline and gear box damage,
repeat "run-in" instructions at beginning of each season
and when moisture and/or condensation seizes inner
friction plates.
To avoid serious injury or death:
Always place tractor in park or set park brake, disengage
power take-off, shut tractor engine off, remove switch key, and
wait for all moving parts to stop before dismounting tractor.
Refer to Figure 5-3:
