TO ADJUST ATTACHMENT CLUTCH
The electric clutch should provide years of service. The clutch has a
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 igni- tion switches are in "OFF" position.
2.Adjust the three nylon Iocknuts until
space between clutch plate and rotor measures .012"at all three slot loca-
tions 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.
