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
opened-out 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 (ref no. 23 in the control assembly parts
list). See Illustrated Parts Book.
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 locks
the traction wheels.
