Refer to this section for information on maintaining the windrower's drive wheels and caster wheels.

5.12.1 Traction Drive

The windrower's traction drive consists of the drive wheels, the tires, and the hydraulic wheel drives. Refer to the following
procedures for information on maintaining the traction drive system.

Inflating Drive Wheel Tire

Follow these procedures to safely inflate the tire on a drive wheel.
DANGER
• Inflate the tire when the wheel is in a safety cage, if
possible.
• Do NOT stand over the tire while inflating it. Use a clip-on
chuck and extension hose.
• NEVER install a tube in a cracked wheel rim.
• NEVER weld a wheel rim.
• Do NOT exceed the maximum inflation pressure, which can
be found on the tire's sidewall.
• Ensure that all the air is removed from a tire before
attempting to remove the tire from the rim.
DANGER
• NEVER use force on an inflated or partially inflated tire. Ensure that the tire is correctly seated before inflating it to
operating pressure.
• Do NOT remove, install, or make repairs to a tire on a rim unless you have the proper equipment and experience to
perform the job. Take the tire and rim to a qualified tire repair shop.
• If the tire is NOT in the correct position on the rim, or if it is overinflated, the tire bead can loosen on one side,
causing air to leak at high speed and with great force. An air leak of this nature can thrust the tire in any direction,
endangering anyone in the area.
DANGER
To prevent bodily injury or death from the unexpected startup of the machine, always stop the engine and remove the
key from the ignition before leaving the operator's seat for any reason.
Perform a daily visual check on the tires to ensure that they have not lost air pressure. Adjust the tire pressure as needed.
Underinflated drive tires can cause sidewall cracks.
To inspect a tire's air pressure level:
1. Shut down the engine, and remove the key from the ignition.
2. Determine the type and size of tire installed on the windrower.
3. Refer to the following table to determine the appropriate tire pressure:
