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.
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.

TO CHECK BRAKE
If tractor requires more than five (5) feet to
stop at highest speed in highest gear on a
level, dry concrete or paved surface, then
brake must be serviced.
You may also check brake by:
1. Park tractor on a level, dry concrete or
paved surface, depress brake pedal
all the way down and engage parking
brake.
2. Disengage transmission by placing
freewheel control in "transmission dis-
engaged" position. Pull freewheel con-
trol out and into the slot and release so
it is held in the disengaged position.
The rear wheels must lock and skid
when you try to manually push the tractor
forward. If the rear wheels rotate, then the
brake needs to be serviced. Contact a
27Sears or other qualified service center.
