Tire Pressure
Service Interval/Specification
Maintain the air pressure in the front and rear tires as
specified. Check the pressure at the valve stem after
every 25 operating hours or yearly, whichever occurs
first. Check the tires when they are cold to get the
most accurate pressure reading.
Pressure: 12 psi (.85 kPa) front and rear

Brake
The brake is on the right side of the rear axle, inside
the rear tire (Fig. 16). If the brake does not hold
securely or stopping power is insufficient, an
adjustment is required.
Checking the Brake
1.
Park the machine on a level surface, disengage
the blade control (PTO), shift into neutral, set
the parking brake, and turn the ignition key to
“OFF” to stop the engine.
2.
If the rear wheels lock and skid when you push
the tractor forward, no adjustment is required.
An adjustment is required if the wheels turn and
do not lock; refer to Adjusting the Brake,
page 19.
Adjusting the Brake
1.
Check the brake before you adjust it; refer to
Checking the Brake, page 19.
2.
To increase braking resistance, tighten the brake
adjusting nut (Fig. 16) 1/8 turn clockwise; then
check the brake again. Continue this adjusting
and checking process until the brake is set
properly.
3.
Push down on the clutch/brake pedal to release
the parking brake.
IMPORTANT: With the parking brake
released, the rear wheels must rotate freely
when you push the tractor. If the brake seems
to “drag,” loosen the adjusting nut slightly
until the wheels rotate freely. If both
conditions cannot be achieved, contact an
authorized service dealer immediately.
