TO ADJUST ATrACHMENT 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 a Sears or other qualified service center.

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 plata.

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.
