TO CHECK BRAKE
If tractor requires more than five (5) feet 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:
• Park tractor on a level, dry concrete or paved surface,
depress brake pedal all the way down and engage
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 manu-
ally push the tractor forward. If the rear wheels rotate, then
the brake needs to be serviced. Contact a qualified service
center.
