TO ADJUST ATTACHMENT CLUTCH
The electric clutch should provide years of
servlce. The clutch has a built-in brake
that stops the pulley-within 5 seconds.
Eventually, the intemal 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/depart-
ment.
_Makesure attachment clutch and igni-
tion switches are in =OFP position.
• Adjust the three nylon Io_knuts until
space between clutch plate and rotor
measures .012" at all three slot loca-
tions cut in the side of brake plate.

TO ADJUST BRAKE

brake system which is mounted on the left
side of the transaxle.
If tractor requires more than six (6) feet
stopping distanceat high speed in high-
est gear, then brake must be adjusted.
• Depress clutch/brake pedal and engage
parking brake.
• Measure distance between brake oper-
ating arm and nut "A" on brake rod.
• If distance is other than 1-3/4", loosen
jam nut and tum nut =A" until distance
becomes 1-3/4". Retighten jam nut
against nut =A".
• Road test tractor for proper stopping
distance as stated above. Readjust if
necessary. If stopping distance is still
greater than six (6)feet in highest gear,
further maintenance is necessary.
