Note: if machine sits outside longer than 30 days and is exposed to rain and humid air, the clutches should be
removed from machine and store in dry area. Clutch facing will soak up moisture and cause the metal plates
to rust badly. When this occur, the break-away torque increases greatly and damage to gearbox, driveline, or

MAINTENANCE SECTION
A slip clutch is incorporated in the PTO driveline. It is designed to slip, absorb the shock load, and
protect the driveline. Clutch torque setting is NOT factory set. If clutch slips excessively, check friction
discs for excessive wear. To adjust clutch,
À rst check length of springs assembled on clutch. Length
should be 1 1/8 (28.5 mm). If not, adjust length of bolt to obtain proper spring length. If additional
adjustment is required, tighten each bolt 1/2 turn. NOTE: DO NOT tighten spring bolts over 1/2 turn at
any adjustment. Excessive tightening can cause clutch to become frozen and not slip which could cause
damage to the tractor PTO, drivelines, or gearbox.
