Maintenance
If the oil is at room temperature (about 75°F
(24°C)), fill only to the “COLD” level.
Check Tire Pressures
Service Interval: Every 40 hours
1. Stop engine, wait for all moving parts to stop, and
remove key. Engage parking brake.
2. Check tire pressure in drive tires.
3. Inflate drive tires to 12–14 psi (83–97 kPa).
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.
Check Condition Of Belts
Service Interval: Every 40 hours
1. Stop engine, wait for all moving parts to stop, and
remove key. Engage parking brake.
2. Remove the three mower deck belt shields
to check mower primary and secondary belt
condition.
3. Look under engine deck to check the pump drive
belt condition.
4. Check all idler arms to be sure they pivot freely.
Lubricate Grease Fittings
Note: See chart for service intervals.
1. Stop engine, wait for all moving parts to stop, and
remove key. Engage parking brake.
2. Lubricate fittings with one to two pumps of
NGLI grade #2 multi-purpose gun grease.
Refer to the following chart for fitting locations
and lubrication schedule.
