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 Mnt-R-0478.

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.
