Checking the Tire Pressure

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 monthly, whichever occurs first
(Fig. 24). Check the tires when they are cold to get the
most accurate pressure reading.
Pressure: 20 psi (138 kPa) front and rear tires

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
PTO, and set the parking brake.
2. Stop the engine, remove the key, and wait for all
moving parts to stop before leaving the operating
position.
3. 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 26.
4. Release the brake and move the drive control rod to
the push position; refer to Pushing the Machine by
Hand, page 20. Wheels should rotate freely.
5. If both conditions are met no adjustment is required.
Adjusting the Brake
1. Check the brake before you adjust it; refer to Checking
m–6522
the Brake, page 26.
2. Release the parking brake; refer to Releasing the
Parking Brake, page 15.
3. To adjust the brake remove the cotter pin and loosen
the brake adjusting nut slightly (Fig. 25).
4. Carefully insert a 0.015 inch (0.38 mm) feeler gauge
between the outer brake pad and rotor disk (Fig. 25).
5. Tighten the brake adjusting nut until slight resistance
is felt on the feeler gauge when sliding it in and out.
Install the cotter pin.
6. Check the brake operation again; refer to Checking the
Brake, page 26.
Important
wheels must rotate freely when you push the mower. If the
0.015 inch (0.38 mm) clearance and free wheel rotation
cannot be achieved contact your service dealer
immediately.
