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 sec onds.
Eventually, the internal brake will wear
which may cause the mower blades to not
engage, or, to not stop as required. Ad-
justments should be made by a qualifi ed
service center.
1. Make sure attachment clutch and igni-
tion switches are in “OFF” po si tion.
2. Adjust the three nylon locknuts until
space between clutch plate and ro tor
measures .012" at all three slot loca-
tions 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.
