specified. Check the pressure at the valve stem after every
25 operating hours or monthly, whichever occurs first
(Fig. 31). Check the tires when they are cold to get the
most accurate pressure reading.

Cleaning Engine Cooling
Systems
Before each use, check and clean cooling screen. Remove
any build–up of grass, dirt or other debris from the engine
air intake. Every 100 hours clean engine cylinder and
cylinder head cooling fins. Also clean around carburetor,
governor levers and linkage. This will help insure
adequate cooling to engine and will reduce the possibility
of overheating and mechanical damage.
1. Clean off engine air intake (Fig. 32).
2. Blow out fins of engine and screen with compressed
air. If area between screen and fins is tightly packed,
remove engine shroud.

Servicing the 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. Remove the key.
2. Place the gear shift in neutral. Rear wheels must lock
and skid when you try to push the tractor forward.
Adjustment is required if the wheels turn and do not
lock; refer to Adjusting the Brake, page 28.
3. Release the parking brake and push the tractor. Wheels
should rotate freely without brake drag.
4. If both conditions are met no adjustment is required.
Adjusting the Brake
The brake adjustment is behind the left side cover (Fig.
33). If the parking brake does not hold securely, an
adjustment is required.
1. Check the brake before you adjust it; refer to Checking
the Brake, page 28.
2. Set parking brake so latch is in second notch. To do
this lift up on parking brake lever and slowly depress
brake pedal and feel when latch is in second notch.
3. To adjust the brake tighten adjustment nut until rear
wheels skid, then tighten an additional 1/2 turn
(Fig. 33).
