Driveline Protection
The drivetrain is protected from shock loads with a four
plate slip-clutch. The slip-clutch must be capable of
slippage during operation. Always do a “clutch run-in”
operation at the beginning of each season and after long
periods of inactivity to remove any oxidation that may
have accumulated on the friction surfaces. Repeat
“clutch run-in” instructions when moisture and/or
condensation seizes the 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.
Clutch Run-In
Refer to Refer to Figure 5-2:
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 by
exactly 2 revolutions. It will be necessary to hold hex
end of retainer bolt in order to count the exact
number of revolutions.
3. Start tractor and engage PTO drive for 2-3 seconds
to permit slippage of the clutch surfaces. Disengage
PTO, then re-engage a second time for 2-3 seconds.
Disengage PTO, shut off tractor, and remove key.
Wait for all components to stop before dismounting
from tractor.
