2.Leaking Tires: When a flat tire occurs, repair or replace immediately. The normal procedure is to remove the wheel and replace it with a spare.

Take the leaking tire to a maintenance area and repair. If a tire is getting soft, park the mower on the nearest level, paved area. If the leaking tire is on a traction wheel, put blocks on each side of the opposite traction wheel and jack up the tire that leaks about an inch off the ground. Loosen and remove the lug nuts and remove the wheel. Mount a spare wheel and tire, replace the lug nuts, and using a torque wrench, tighten them to 60 ± 10 lb-ft.

If the leaking tire is on a front caster wheel, block both traction wheels and raise the caster wheel so that the tire is an inch off the ground. Loosen and remove the locknut from the axle assembly and pull the axle assembly from the caster yoke. The wheel and two spacer sleeves will drop free. Slip the axle assembly through one side of the caster yoke, through a spacer sleeve, a spare wheel, the other spacer sleeve and finally through the other side of the caster yoke. Then tighten the locknut on the end of the axle assembly.

Lower the mower off the jack and continue mowing. The wheel with the leaking tire should be taken to the maintenance area, the tire inflated to 20 psi and the wheel placed in a large bucket of water. Carefully inspect the tire, rim and valve for escaping air bubbles which indicate a leak. Mark each leak with a yellow marking crayon and then deflate the tire to 8 psi and repeat the inspection. If the leaks you find are pin hole size to 1/16" diameter, the tire can be repaired using an aerosol can of tire inflater and latex sealer available from any auto supply store. Follow the directions on the can. If the leaks are larger than 1/16" diameter, the tire can be repaired with rubber plugs also available in a kit from any auto supply store. If the tire bead is damaged, a tube will have to be installed in the tire or the tire will have to be replaced.

3.Creeping: Creeping is the slight forward or backward movement of the mower when the throttle is on and the lapbars are in the neutral position. If your mower creeps refer to Steering lever Adjustments Section G4, page 23.

F.Brakes

While the mower is in motion, all braking is performed dynamically through the hydraulic pumps and traction motors, controlled by the two steering levers. When the mower is parked with the engine shut off, the hydraulic system locks the traction wheels.

Note: To move the mower forward or in reverse by pushing, you must release the dynamic braking. Locate the valves on the pump. Turn valves

counter-clockwise (using a standard 7/16” wrench) one quarter turn to push the unit. After pushing the mower to the desired location, return both valves to the operating position by turning the valve clockwise, but do not overtighten (See photo below).

When the mower is parked with the engine running and the steering levers in the neutral position, the parking brakes should be applied. The parking brakes are drum- type brakes mounted on each traction wheel. They are both engaged by the same operating lever.

1.Adjustments: The parking brake handle is an overcenter lever that should engage with moder- ate force.

Note: To increase parking brake capacity, adjust brake cables at the brake arms equally. Adjust the cable housing nuts one full turn and check parking capacity. Repeat if parking brake does not hold.

2.Repair: The mower is equipped with drum brakes and will not normally require mainte- nance. If they are not working properly, please contact your service center.

G.Hydraulic System

WARNING:

Never overfill the hydraulic units. Damage can occur if the oil level is not within the proper oper- ating range.

Note: When adding hydraulic oil, do so in small quantities and recheck the oil level before adding more. It is important that you do not over- fill the reservoir to allow for fluid expansion.

1.Hoses: Check the hoses from the hydraulic oil tank to the oil filter to the hydraulic lines daily for leaks or abrasion and replace any damaged
