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 brakewill 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 attachmentclutch 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 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.
