Slip Clutch
A slip clutch is incorporated in the PTO driveline. It is designed to slip, absorb the shock load, and protect the
driveline.
After the first hour of operation, the slip clutch should be checked for overheating. After this first check, the
slip clutch should be checked weekly or anytime there is overheating. To adjust the slip clutch, tighten the
spring bolts 1/8 (maximum) turn at a time. Bolts should NEVER be adjusted to the point where the springs are
compressed solid. Minimum spring length is 1-1/8".
The slip clutch should be checked periodically and ad justed to compensate for we ar. The lining plates are 1/8"
thick when new. Replace after 1/3 2" wear. If the mower has been idle for an extend ed period of time, or in wet
weather, before op erating check to be sure the friction lining plates are not frozen or rusted together. Should
this freezing occu r refer to the procedu re described in the "Seaso nal Clutch Main tenance" s ection on the n ext
page.
There are four friction lining plates in the slip clutch. These should be checked we ekly for oil or grease, we ar,
and moisture which could cause corrosion on the drive plates.
