SERVICE AND ADJUSTMENTS
TO ADJUST ATTACHMENT CLUTCH
(See Fig. 25)
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 locknuts until space between
clutch plate and rotor measures .012" at all three slot
locations cut in 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.
