Electric PTO Clutch Burnishing Procedure
Note: This procedure needs to be done only when
installing a new clutch.
The clutch should be burnished as part of the pre-
delivery service, or whenever a new clutch is installed.
Burnishing polishes the clutch plate, allowing for smooth
clutch engagement.
With deck drive belt installed, run the engine at half
throttle. Engage and disengage the mower 5 times (10
seconds on/10 seconds off).
Increase engine RPM to 3/4 to full throttle. Engage and
disengage mower 5 times (10 seconds on/10 seconds
off).
Using a feeler gauge, check the clutch air gap at each
of the 3 adjustment slots. The gap should be between
0.015” (0.381mm). Make sure the gauge is inserted
between the armature and the rotor friction surfaces.
Adjust the clutch as necessary (Fig. 822).
