Tire Pressure

Service Interval/Specification
Maintain the air pressure in the front and rear tires at
20 psi (138 kPa). Check the pressure at the valve
stem after every 25 operating hours or monthly,
whichever occurs first (Fig. 17). Check the tires when
they are cold to get the most accurate pressure
reading.

Brake
Always set the parking brake when you stop the
machine or leave it unattended. If the parking brake
does not hold securely, an adjustment is required.
Checking the Brake
1. Park the machine on a level surface, disengage
the power take off (PTO), set the parking brake,
and turn the ignition key to "OFF" to stop the
engine. Remove the key.

push the tractor forward. Adjustment is required
if the wheels turn and do not lock; refer to
Adjusting the Brake, page 34.

The wheels should rotate freely.
