Slip Clutch Adjustment - Bush Hog SQ84T SQUEALER Operator's Manual

SLIP CLUTCH OPERATIONAL CHECK
NOTE: After implement has been stored for 30 days or more, perform the following operational check:
1. Loosen eight nuts retaining clutch springs 1/3 turn or until spring can be turned with fingers.
2. With tractor at idle speed, engage tractor PTO drive for 2-3 seconds. Clutch should lip without turning
blades. If clutch does not slip, contact your authorized Bush Hog dealer.
3. Retighten nuts to within 1/64" of original position. Initial spring length is shown in Figure Below.
Overtightening spring nuts may cause damage to implement and/or tractor due to incorrect
slip clutch torque setting. Always follow the proper adjustment procedure.

SLIP CLUTCH ADJUSTMENT

The slip clutch is factory present to the correct torque for protecting implement and tractor. Periodic adjustment
is recommended. Should adjustment be needed, first check to be sure all spring lengths are the same. Initial
spring length is shown in Figure Above. 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 neces-
sary, 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 you Bush Hog dealer.
Do not overtighten nut and cause spring to become solid as this will cause shaft to fail.
