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.
!
WARNING
Always disengage PTO, engage parking brake, shut off
tractor, remove ignition key, and wait for all moving parts to
come to a complete stop before dismounting tractor to make
adjustments.
Refer to Figure 5-3:
1.
Using a pencil or other marker, scribe a line across the
exposed edges of the clutch plates and friction discs.

2.
Carefully loosen each of the 8 spring retainer nuts on
the clutch housing a total of EXACTLY 2 revolutions.
It will be necessary to hold the hex end of the retainer
bolt in order to count the exact number of revolutions.
3.
Start tractor and engage driveline for 2-3 seconds to
permit slippage of the clutch surfaces. Disengage
the PTO, then re-engage a second time for 2-3
seconds. Disengage the PTO, shut off tractor, and
remove key. Wait for all components to stop before
dismounting from tractor.
4.
Inspect clutch and ensure that scribed markings
made on the clutch plates have changed position.
Slippage has not occurred if any two marks on the
friction disc and plate are still aligned.

IMPORTANT: If clutch run-in procedure indicated
that one or more friction disks did not slip, the clutch
must be disassembled to separate the friction discs.
