Servicing the Brake

The brake is on the right side of the rear axle, inside the
rear tire (Fig. 20). If the brake does not hold securely or
stopping power is insufficient, an adjustment is required.

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.
5. Remove the ignition key.
6. Move the drive control wire to the Push position; refer
to Pushing the Tractor Manually on page 17.
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 on page 23.
Adjusting the Brake
1. Check the brake before you adjust it; refer to Checking
the Brake on page 23.
2. Remove the brake arm spring (Fig. 20).
3. Remove the cotter pin that secures the brake adjusting
nut and slightly loosen the nut (Fig. 20).
4. Insert a 0.015 in. (0.38 mm) feeler gauge between the
brake disc and the brake puck (Fig. 20).
5. Tighten the nut until you feel a slight resistance on the
feeler gauge when you slide it in and out.
6. Install a new cotter pin and attach the brake arm spring.
7. Check the brake operation again; refer to Checking the
Brake, page 23.

Important
With the parking brake released, the rear
wheels should rotate freely when you push the tractor. If
you cannot set the 0.015 in. (0.38 mm) clearance and get
free wheel rotation, contact an Authorized Service Dealer
immediately.
Greasing and Lubricating the
Tractor
Grease the tractor after every 25 operating hours or once a
year, whichever occurs first. Grease more frequently when
operating conditions are extremely dusty or sandy.
Grease Type: General-purpose grease
How to Grease
1. Disengage the blades (PTO).
2. Set the parking brake.
3. Stop the engine and wait for all moving parts to stop.
4. Remove the ignition key.
5. Clean the grease fittings with a rag.
6. Scrape any paint off of the front of the fittings.
7. Connect a grease gun to the fitting and pump grease
into the fittings.
8. Wipe up any excess grease.
Where to Add Grease
Lubricate the front wheels and steering spindles until
grease begins to ooze out of the bearings (Fig. 21).

Checking the Tire Pressure

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 yearly, whichever occurs first
(Fig. 22). Check the tires when they are cold to get the most
accurate pressure reading.
