TO ADJUST STEERING WHEEL ALIGNMENT
If steering wheel crossbars are not horizontal (left to right)
when wheels are positioned straight forward, remove steer-
ing wheel and reassemble per instructions in the Assembly
section of this manual.
FRONT WHEEL TOE-IN/CAMBER
The front wheel toe-in and camber are not adjustable on
your tractor. If damage has occurred to affect the front
wheel toe-in or camber, contact your nearest authorized
service center/department.

TO ADJUST ATTACHMENT CLUTCH
(See Fig. 27B)
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 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.

ignition key to “OFF” position, and engage parking
brake.
Adjust motion control lever by tightening adjustment
