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:

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.
