Maintenance

Note: Front caster tires have permanent tire sealant installed.

For Serial Nos. 600,000 and Higher: Semi-pneumatic caster tires do not need to be inflated.

Note: Do Not add any type of tire liner or foam fill material to the tires. Excessive loads created by foam filled tires may cause failures to the hydro drive system, frame, and other components. Foam filling tires will void the warranty.
