Servicing the Brake
The brake is located on the right side of the rear axle, inside
the rear tire (Fig. 20).

1. Brake adjusting nut
If the tractor takes more than 1 meter (3 ft.) to stop at high
speed in the highest gear, adjust the brake.
Checking the Brake
1.
Park the tractor on a level surface.
2.
Disengage the blades (PTO).
3.
Set the parking brake.
4.
Stop the engine and wait for all moving parts to stop.
5.
Remove the ignition key.
6.
Pull the drive control out to the Push position (Fig. 14).
7.
If the rear wheels lock and skid when you push the
tractor forward, you do not need to adjust the brake. If
the wheels turn and do not lock, adjust the brake; refer
to Adjusting the Brake below.
Adjusting the Brake
1.
Check the brake before you adjust it; refer to Checking
the Brake above.
2.
Ensure that the drive control is in the Operate position
(Fig. 14) and that the parking brake is on.
3.
Turn the brake adjusting nut clockwise until you cannot
push the tractor (Fig. 20).
4.
Release the parking brake and ensure that the rear
wheels rotate freely when you push the tractor. If they
do not, turn the brake adjusting nut counterclockwise
just enough so that you can push the tractor.
5.
Check the brake operation again; refer to Checking the
Brake above.
Checking the Tire Pressure
Maintain the air pressure in the front tires at 120 kPa and in
the rear tires at 100 kPa. Check the pressure at the valve
stem (Fig. 21) after every 25 operating hours or yearly,
whichever comes first. Check the tires when they are cold
to get the most accurate pressure reading.
