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 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 AND ADJUST 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 checked and adjusted.
TO CHECK BRAKE
• Park tractor on a level, dry concrete or paved surface,
depress clutch/brake pedal all the way down and en-
gage parking brake.
Disengage transmission by placing freewheel control
in "transmission disengaged" position. Pull freewheel
control 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, the brake
needs to be adjusted or the pads need to be replaced.
