RETAINER SPRING DRIVE BELT TENSION HANDLE 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 locknuts until space between clutch plate and rotor measures .012" at all three slot locations cut in 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.
