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 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, then the brake
needs to be serviced. Contact a Sears or
other qualified service center.
FRONT WHEEL TOE-IN/CAMBER
Your new tractor front wheel toe-in and cam-
ber is set at the factory and is normal. The
front wheel toe-in and camber are not adjust-
able. If damage has occurred to affect the
factory set front wheel toe-in or camber, con-
tact a Sears or other qualified service center.
TO REMOVE WHEEL FOR REPAIRS
1. Block up axle securely.
2. Remove axle cover, retaining ring and
washers to allow wheel removal (rear
wheels have a square key - Do not lose).
3. Repair tire and reassemble.
NOTE: On rear wheels only: align grooves in
rear wheel hub and axle. Insert square key.

flat tires due to slow leaks, purchase and
usetire sealant from Sears. Tire sealant also
