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 atl 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 10
cycles to wear in clutch plate.
