If a slip clutch is incorporated in the PtO driveline,
it is designed to slip, absorb the shock load, and
protect the driveline. this clutch has 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 until Belleville Spring is
flat and then loosen each of them 2 turns.
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 cutter 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.
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

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/corroded
together. Before using the cutter use the following procedure to make sure the clutch will slip and
give the overload protection required.
1. Loosen nuts on springs until the springs are free, yet remain secure on bolts.
2. attach cutter to tractor and start the tractor. Set the engine speed at 1200 RPm.
3. mark outer plates as shown in Figure mnt-R-0090.
4. engage the PtO (approximately one second) and then quickly disengage it. the friction lining
plates should break loose (check the mark).
