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.

FRONT WHEEL TOE-IN/CAMBER

Your new tractor front wheel toe-in and camber is set at the factory and is normal. The front wheel toe-in and camber are not adjustable. If damage has occurred to affect the factory set front wheel toe-in or camber, contact a qualified service center.

TO REMOVE WHEEL FOR REPAIRS (See Fig. 28)

•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.
