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 your
nearest authorized service center/
department.
• Make sure attachment clutch and
ignition switches are in "OFF" position.
• 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 installing a new electric
clutch, run tractor at full throttle and
engage and disengage electric clutch !0
cycles to wear in clutch plate.
