MAINTENANCE
SLIP CLUTCH
A slip clutch is incorporated in the PTO driveline. It
is designed to slip, absorb the shock load, and
protect the driveline. The clutch has a single disc
spring with 6 adjusting nuts.
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 disc
clutch, tighten the 6 bolts 1/8 (maximum) turn at a
time.
The slip clutch should be checked periodically and
adjusted to compensate for wear. The lining plates
are 1/8” thick when new. Replace after 1/32” wear. If
the mower has been idle for an extended period of
time, or in wet weather, before operating check to be
sure the friction lining plates are not rusted/corroded
together. Should this occur refer to the procedure
described in the “Seasonal Clutch Maintenance”
section on the next page.
There are two friction lining plates in the slip clutch.
These should be checked weekly for oil or grease,
wear, and moisture which could cause corrosion on
the drive plates
