TOCHECK
B RAKE
If tractor requires more than five (5) feet (1,5
m) 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.
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.
4. Replace washers and snap retaining ring
securely in axle groove.
5. Replace axle cover.
NOTE: To seal tire punctures and prevent
flat tires due to slow leaks, purchase and
use tire sealant from Sears. Tire sealant also
prevents tire dry rot and corrosion.
