Brake

The brake is on the right side of the rear axle, inside the
rear tire (Fig. 21). If the tractor requires more than one
meter to stop at high speed in the highest gear, then the
brake must be adjusted.
Checking the Brake
1. Park the machine on a level surface, disengage the PTO,
set the parking brake, stop the engine, and remove the
ignition key.
2. Pull the drive control out to the Push position (Fig. 14).
3. If the rear wheels lock and skid when you push the
tractor forward, no adjustment is required. An
adjustment is required if the wheels turn and do not
lock; refer to Adjusting the Brake, page 22.
Adjusting the Brake
1. Check the brake before you adjust it; refer to Checking
the Brake, page 22.
2. Ensure the drive control is in the Operate position
(Fig. 14) and the parking brake is on.
3. To adjust the brake, turn the brake adjusting nut
clockwise until you can not push the tractor (Fig. 21).
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 until you can push the tractor.
5. Check the brake operation again; refer to Checking the
Brake, page 22.

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 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.

Greasing and Lubrication

Service Interval/Specification
Grease the machine 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 PTO, set the parking brake, stop the
engine, and remove the ignition key.
2. Clean the grease fittings with a rag. Make sure to scrape
any paint off of the front of the fitting(s).
3. Connect a grease gun to the fitting. Pump grease into
the fittings.
