Slip Clutch
A slip clutch is incorporated in the PTO driveline. It is designed to slip, absorb the shock load, and protect the
driveline.
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 compression length is 1-1/4”.

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 frozen or rusted together. Should
this freezing occur refer to the procedure described in the “Seasonal Clutch Maintenance” section on the next

Seasonal Clutch Maintenance
1. It is important that the clutch lining plates 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 mower use the following procedure to make sure the clutch will slip and give the overload
protection required.

protection required.
2. Loosen nuts (Figure Mnt-FL-0003) on springs until the springs can freely rotate, yet remain secure on
bolts.
3. Attach mower to tractor and start the tractor. Set the engine speed at 1200 RPM.
4. Mark outer plates as shown in Figure Mnt-FL-0003.
5. Engage the PTO (approximately one second) and then quickly disengage it. The friction lining plates
should break loose (check the mark).
6. Turn tractor off and tighten the nuts on the springs to their original position of 1-5/16” compressed spring
length.
