TO ADJUST ATTACHMENT 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. Ad- justments should be made by a qualiﬁed service center.

1.Make sure attachment clutch and igni- tion switches are in “OFF” position.

2.Adjust the three nylon locknuts 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.
