Checking the Tire Pressure
Service Interval: Every 25 hours/Yearly (whichever
comes first)
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 (Figure 35). Check the tires when they are
cold to get the most accurate pressure reading.

Checking the Brake
Service Interval: Before each use or daily
1. Park the machine 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
(Figure 15).
7. If the rear wheels lock and skid when you push the
machine 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.
Adjusting the Brake
1. Check the brake before you adjust it; refer to
Checking the Brake.
2. Ensure that the drive control is in the Operate
position (Figure 15) and that the parking brake is on.
3. Turn the brake adjusting nut clockwise until you
cannot push the machine (Figure 36).
4. Release the parking brake and ensure that the rear
wheels rotate freely when you push the machine.
If they do not, turn the brake adjusting nut
counterclockwise just enough so that you can push
the machine.
5. Check the brake operation again; refer to Checking
the Brake.
