b. Front Wheel—25 psi max; 20-25 psi recom-
mended
c. Cutting Deck Ball Wheels—Solid Polyurethane.
Use the Following guidelines for maintaining the tires:
a. Balance inflation pressure between the rear tires
to help maintain straight travel (see tire side wall
for proper inflation pressure).
b. Keep the valve caps tightened to prevent air pres-
sure loss.
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 trac-
tion 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
If the leaking tire is on a front wheel, set park brake,
block both traction wheels and raise the front 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 yoke. The wheel and
two spacer sleeves will drop free. Slip the axle
assembly through one side of the yoke, through a
spacer sleeve, a spare wheel, the other spacer sleeve
and finally through the other side of the 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 back-
ward movement of the mower when the throttle is on
and the speed control pedal is in the neutral position.
If your mower creeps, refer to speed control Adjust-
ment Section F4, page 21.

E. Brakes
While the mower is in motion, all braking is performed
dynamically through the hydraulic pumps and traction motors,
controlled by the speed control pedals. If the brake pedal is
pushed, it will return the forward and reverse pedals to neutral
and add the drum brake force to the hydrostatic brake. When the
mower is stationary with the engine running, the hydraulic
system locks the traction wheels. If the engine is shut off, the
park brake should be engaged. The park brake is engaged by
pushing the pedal down and the latch lever until it latches. To
release, push it a second time without pushing the latch lever.
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)

Left Side Pump
When the mower is parked with the engine running and the
speed control pedal 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 pedal should
engage with moderate 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 maintenance. If they
are not working properly, please contact your service
center.
Note:
The brake can be applied at anytime to func-
tion as a service or an emergency brake. When it is
applied, the forward and reverse pedals will return to
their neutral positions.
