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 do the following.

a.Jack up rear of unit.

b.Place Lapbars in neutral opened-out position.

c.Locate jam nuts. See Illustrated Parts Book (Control Assembly).

d.Loosen jam nuts on both ends of rod connectors. (ONLY if mower creeps.)

e.Start unit and push throttle all the way on.

f.Locate the left and right rod connectors between each jam nut. See Control assembly in the Illustrated Parts Book.

g.If unit creeps forward rotate counter-clockwise. And if unit creeps in reverse, rotate clockwise.

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 dramatically hinders movement to the traction wheels. When the mower is parked, the parking brake should be engaged.
