TO ADJUST ATTACHMENT CLUTCH
The electdc clutch should provide years of
service. The clutch has a built-in brake that
stops the pulley within 5 seconds. Eventu-
ally, the intemal brake will wear which may
cause the mower blades to not engage, or,
to not stop as required. Adjustments
should be made by your nearest autho-
rized service center/department.
1. Make sure attachment clutch and
ignition switches are in "OFF" position.
2. Adjust the three nylon Iocknuts until
space between clutch plate and rotor
measures .012" at all three slot
locations cut in the side of brake plate.
NOTE: After installinga new electdc
clutch, run tractor at full throttleand
engage and disengage electdc clutch 10
cycles to wear in clutch plate.
