TIRE MAINTENANCE
This mower is equipped with tubeless tires of the size and
type listed below:
Size
13x5x6
Tire Air Pressure
Check the air pressure in all tires before use. Improper air
pressure will affect handling, steering response, traction,
tire life, level cutting, and operator comfort. Be sure tires
are inflated to the pressure shown below.
NOTE: Tire pressure should only be measured or
adjusted when tires are cold.
Recommended
Pressure
WARNING:
Check the tire pressure carefully while inflating. Too much
air in the tire could cause the tire to burst, causing seri-
ous personal injury.
WARNING:
Maintaining correct air pressure in the tires is very impor-
tant. Too little pressure could allow the tire to rotate off
the wheel rim. Too much pressure could cause the tire to
burst. Failure to maintain correct air pressure in the tires
could cause problems with mower operation and stability,
causing death or serious personal injury.
TIRE REPAIR
If a leak or flat tire occurs due to a puncture, the tire may be
repaired using a plug-type patch. If the damage is from a
cut, or if the puncture cannot be repaired using a plug, the
tire should be replaced.
REPLACING TIRES
When tires are worn, the traction of the mower will be de-
creased, which increases the chance of having an accident.
Tires should be replaced when the depth on the tread is
0.16 in. (4 mm) or less, or any time there is damage to the
tire. Always use identical replacement tires. Using improper
tires on the mower could cause loss of control, which could
cause serious personal injury.
Have tires replaced by an authorized service center or a
qualified tire repair station.

ADJUSTING THE BRAKES
See Figure 21.
DANGER:
Ensure the brakes are properly functioning at all times and
prior to each use. Improper brake function can cause loss
of control in an emergency situation and result in death
or serious personal injury.
Being able to stop the mower properly is critical to mowing
safety. If you've noticed your mower traveling farther before
stopping when you depress the brake pedal, the brakes may
need adjusting.
To test:
 Park the mower on a level surface and set the parking
brake.
 Place the drive levers in the open position.
 Stand behind the mower and try to push it forward. If the
rear tires turn, the brakes need to be tightened.
To tighten:
 Locate the brake adjustment nuts along the frame in front
of each of the rear wheels.
 Turn each adjustment nut 1/4 turn clockwise, then try
again to push the mower.
 Continue rotating each nut 1/4 turn and testing until the
mower can no longer be moved by pushing.
After final adjustment, test the brakes by driving the mower
at normal speed on flat ground to be sure the mower stops
quickly when the brake pedal is depressed.
