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 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 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 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. If the leaks are larger than 1/16" diameter, the tire can be repaired. If the tire bead is damaged, the tire can be repaired 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 on transaxle control arms. (They are on the vertical linkage on the front of the transaxles)
d.Loosen jam nuts on both ends of rod con- nectors.
e.Start unit and push throttle all the way on.
f.If unit creeps forward, rotate vertical rod links
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 release levers at the rear of the machine. Pull them toward the rear and lower the wide area of the rod into the keyhole slot. (See photo below).
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 gear/pawl brakes mounted on each traction wheel. They are both engaged by the same operating lever.
1.Adjustments: The parking brake handle is a lever in a “j” slot that should engage with mod- erate force. The parking brakes provide a positive means to hold a machine stationary that is similar to “Park” on an automobile.
Note: The parking brakes normally do not need to be adjusted.
To adjust either brake individually, loosen the jam nuts on the cable near the brake arm on the transaxle. Adjust the nuts so that the brake/pawl comes closer to the gear, but not in contact with the gear teeth.
2.Repair: The mower is equipped with external gear/pawl brakes and will not normally require maintenance. If they are not working properly, please contact your service center.
