Drivelines With Slip Clutches
WARNING
!
To avoid serious injury or death:
•
Always follow “Tractor Shutdown Procedure” provided in
this manual before dismounting the tractor.
•
A slip clutch that has been in use or has slipped for as little
as only two or three seconds during run-in may be too hot
to touch. Allow a hot clutch to cool before working on it.
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.
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 the friction
surfaces. Repeat “run-in” instructions at the beginning of
each season and when moisture and/or condensation
seizes the inner friction plates.
Refer to Figure 5-4 to determine which friction clutch your
cutter has. Follow “run-In” instructions on the following
pages for your specific clutch type.

IMPORTANT:
Prior to initial operation and after 10
days of inactivity, slip friction disks to remove
oxidation and moisture. Moisture allows disks to slip
easily. Oxidation can prevent disk from slipping
causing driveline damage. This damage is NOT
