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 ft-lbs.
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 back-
ward 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 the neutral position.
c. If the tires are rotating, the neutral position that
side transaxle linkage will need to be adjusted.
Contact your service representative.
F. 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)
.
When the mower is parked with the engine running and the
steering levers in the neutral position, the parking brakes
should be applied. The parking brakes are gear/pawl brakes
mounted internally within each transaxle. They are both
engaged by the same operating lever.
1. Adjustments: The parking brake handle is a lever
in a slot that should engage with moderate 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 cable becomes shorter.
2. Repair: The mower is equipped with internal
gear/pawl brakes and will not normally require
maintenance. If they are not working properly,
please contact your service center.
G. Hydraulic System
1. Hydrostatic Pumps and Motors: The pumps in
the transaxles are the hardest-working components
in the hydraulic system. They are in operation all
the time the engine is running. Because of
extremely close tolerances, wear is an important
factor in their life.
Note:
The pumps and motors are not owner-
repairable. If a pump fails, contact your Cub Cadet
dealer. Do not disassemble the pump/motors.
2. Steering Lever Adjustments: Place the mower
on level ground with the engine running, parking
brake off and steering levers in the neutral posi-
tion. If the mower begins to creep, contact your
service representative.
