TO ADJUST ATTACHMENT CLUTCH
The electric clutch should provide years
of service. The clutch has a built-in brake
that stops the pulley within 5 seconds.
Eventually, the internal brake will wear
which may cause the mower blades to
not engage, or, to not stop as required.
Adjustments should be made by a Sears
or other qualified service center.
1. Make sure attachment clutch and
ignition switches are in “OFP position.
2. Adjust the three nylon locknuts until
space between clutch plate and rotor
measures .012" at all three slot
locations cut in the side of brake plate.
NOTE; After installing a new electric
clutch, run tractor at full throttle and
engage and disengage electric clutch 10
cycles to wear in clutch plate.
