ADJUSTMENTS

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 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 all 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.
