6.1.9Check hydraulic oil level: Service Interval: 40 hrs.
a)Make sure mower is on a level surface.
b)Stop engine, wait for all moving parts to stop.
c)Visually inspect the sight gauge on hydraulic tank. Oil level should be visible to top of sight gauge. If not, clean area around hydraulic reservoir cap, remove cap, and add oil as specified in Section 2.7 (Specifications). Replace cap.
6.1.10Check tire pressures:
Service Interval: 40 hrs.
a)Stop engine, wait for all moving parts to stop, and remove key.
b)Inflate tires to pressures specified in Section 2.8 (Specifications).
c)See Section 8.1 for further information.
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.
6.1.11Check battery charge:
Service Interval: Monthly
Allowing batteries to stand for an extended period of time without recharging them will result in reduced performance and service life. To preserve optimum battery performance and life, recharge batteries in storage when the open circuit voltage drops to 12.4 volts.
Note: To prevent damage due to freezing, battery should be fully charged before putting away for winter storage.
a)Check the voltage of the battery with a digital voltmeter. Locate the voltage reading of the battery in the table below and charge the battery for the recommended time interval to bring the charge up to a full charge of 12.6 volts or greater.
IMPORTANT: Make sure the negative battery cables are disconnected and the battery charger used for charging the battery has an output of 16 volts and 7 amps or less to avoid damaging the battery (see chart below for recommended charger settings).
Voltage | Percent | Maximum |
| Charging Interval | |
Reading | Charge | Charger Settings |

| ||
12.6 or greater | 100% | 16 volts/7 amps | No Charging Required | ||
12.4 – 12.6 | 75 | – 100% | 16 volts/7 amps | 30 Minutes | |
12.2 – 12.4 | 50 | – 75% | 16 volts/7 amps | 1 | Hour |
12.0 – 12.2 | 25 | – 50% | 14.4 volts/4 amps | 2 | Hours |
11.7 – 12.0 | 0 – 25% | 14.4 volts/4 amps | 3 | Hours | |
11.7 or less | 0% | 14.4 volts/2 amps | 6 | Hours or More | |
6.1.12 Inspect Belt Wear:
Service Interval: 40 hrs.
a)Stop engine, wait for all moving parts to stop, and remove key.
b)Remove the three mower deck belt shields to check mower primary and secondary belt condition.
c)Look under engine deck to check the transmission drive belt condition.
d)Check all idler arms to be sure they pivot freely.
