4-5 SLIP CLUTCH OPERATIONAL CHECK
After the implement has been stored for 30 days or more, perform the following operational check:
A. Loosen eight nuts retaining clutch springs 1/3 turn or until spring can be turned with fingers.
B. With tractor at idle speed, engage tractor PTO drive 2-3 seconds. Clutch should slip without
turning blades. If clutch does not slip, contact your authorized dealer.
C. Retighten nuts to original position. Initial spring lengths are shown in Figure 4-5.
IMPORTANT:
FAILURE TO RETIGHTEN NUTS TO ORIGINAL POSITION MAY CAUSE DAMAGE TO
IMPLEMENT AND/OR TRACTOR DUE TO IMPROPER SLIP CLUTCH TORQUE SETTING
4-6 SLIP CLUTCH ADJUSTMENT
The slip clutch is factory preset to the correct torque for protecting
implement and tractor. Periodic adjustment is recommended; refer
to section 4-5. Should adjustments be needed, first check to be sure
all spring lengths are the same. Initial spring lengths are shown in
Figure 4-5. If necessary, adjust nut on any spring that is unequal.
Adjust all eight spring retaining nuts 1/3 of a turn (2 flats on a nut)
and check clutch slippage. If further adjustment is necessary, do so
in 1/3 turn increments. Adjust only to provide sufficient torque to
prevent slippage under normal conditions. Occasional slippage is
normal for driveline protection. If satisfactory results cannot be
obtained, consult your authorized dealer.
