Check Condition Of Belts

Maintenance

4.Inflate tires to pressures stated above. Measure the circumference of each drive tire. Adjust tire pressures within the above range to try to make tire circumferences match as closely as possible.

5.For Serial Nos. 599,999 and Lower: Check the tire pressure in the pneumatic front caster tires. Adjust the tire pressure to 16 psi (110 kPa).

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.
