SERVICE AND ADJUSTMENTS

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.

•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.

TO START ENGINE WITH A WEAK BATTERY (See Fig. 29)

WARNING: Lead-acid batteries gen- erate explosive gases. Keep sparks, flame and smoking materials away from batteries. Always wear eye protection when around batteries.

If your battery is too weak to start the engine, it should be recharged. (See "BATTERY" in the MAINTENANCE sec- tion of this manual).

If “jumper cables” are used for emergency starting, follow this procedure:

IMPORTANT: YOUR TRACTOR IS EQUIPPED WITH A 12 VOLT SYSTEM. THE OTHER VEHICLE MUST ALSO BE A 12 VOLT SYSTEM. DO NOT USE YOUR TRACTOR BATTERY TO START OTHER VEHICLES.

TO ATTACH JUMPER CABLES -

•Connect one end of the RED cable to the POSITIVE

(+)terminal of each battery(A-B), taking care not to short against tractor chassis.

•Connect one end of the BLACK cable to the NEGATIVE (-) terminal (C) of fully charged battery.

•Connect the other end of the BLACK cable (D) to good chassis ground, away from fuel tank and battery.

TO REMOVE CABLES, REVERSE ORDER -

•BLACK cable first from chassis and then from the fully charged battery.

•RED cable last from both batteries.
