SERVICE AND ADJUSTMENTS
TO CHECK BRAKE
If tractor requires more than five (5) feet (1,5 m) to stop at
highest speed in high est 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 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, then the
brake needs to be serviced. Contact a qualified service center.
TO REMOVE WHEEL (See Fig. 41)
• Block up axle securely.
• Remove axle cover, retaining ring and washers to allow
wheel removal (rear wheel contains a square key - Do
not lose).
• Repair tire and reassemble.
• On rear wheels only: align grooves in rear wheel hub
and axle. Insert square key.
• Replace washers and snap retaining ring securely in
axle groove.
• Replace axle cover.
NOTE: To seal tire punctures and prevent flat tires due
to slow leaks, tire sealant may be purchased from your
local parts dealer. Tire sealant also prevents tire dry rot
and corrosion.
