Slip Clutch Adjustment - Bush Hog 2814 Operator's Manual

SEASONAL CLUTCH MAINTENANCE
It is important that the clutches slip when an obstacle or load heavier than the clutch setting is encountered.
Therefore, if the machine sits outside longer than 30 days and is exposed to rain and/or humid air it is
important to make sure that the clutch lining plates are not rusted/frozen together. Before using the cutter use
the following procedure to make sure the clutch will slip and give the overload protection required.
1. Loosen eight nut 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 slip 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 lengths are shown in Figure Mnt-R-0476.
Failure to retighten spring nuts to original position may cause damage to implement and/or
tractor due to improper slip clutch torque setting.
Do not over-tighten nut and cause spring to become solid as this will cause shaft to fail.

SLIP CLUTCH ADJUSTMENT

The slip clutch is factory present to the correct torque for protecting implement and tractor. Periodic adjustment
is recommend. Should adjustment be needed, first check to be sure all spring lengths are the same. Initial
spring lengths are shown in Figure Mnt-R-0476. If necessary, adjust nut on an 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 drivetrain protection. If satisfactory results cannot be
obtained consult your Bush Hog dealer.
