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
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
a.Jack up rear of unit.
b.Place Lapbars in neutral
c.Locate jam nuts. (Reference control assembly in parts list).
d.Loosen jam nuts on both ends of rod con- nectors. See Control Assembly in the Illus- trated Parts Book (ONLY if mower creeps.)
e.Start unit and push throttle all the way on.
f.If unit creeps forward rotate rear rod con- nectors
Adjust the appropriate rod connector. The left rod for the left side of the mower and the right rod for the right side of mower. Afterward, retighten jam nuts.
E. 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
Hydro Release Valve
When the mower is parked with the engine running and the steering levers opened out in the neutral position, the parking brakes should be applied. The parking brakes are
1.Adjustments: The parking brake handle is an overcenter lever that should engage with moderate force.
Note: To increase parking brake capacity tighten the brake rods going back to the brake arms equally. Tighten rods one full turn and check parking capacity. Repeat Step.
To adjust either brake individually, tighten the hex nut in a clockwise direction one full turn looking down the
