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 near est
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.
