SLIP CLUTCH OPERATIONAL CHECK
NOTE:
After implement has been stored for 30 days or more, perform the following operational check:
1.
Loosen 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 s 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 Mnt-R-0475.
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 Mnt-R-0475. 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 you Bush Hog dealer.
Do not overtighten nut and cause spring to become solid as this will cause shaft to fail.
All Safety Shields, Guards and Safety devices including (but not
limited to) - the Deflectors, Chain Guards, Steel Guards, Gearbox
Shields, PTO integral shields, and Retractable Door Shields should
be used and maintained in good working condition.
All safety
devices should be inspected carefully at least daily for missing or
broken components.
Missing, broken, or
worn items must be
replaced at once to reduce the possibility of injury or death from
thrown objects, entanglement, or blade contact.
