General Information

Operator's Manual

The Operator's Manual provides information regarding
the operation, general maintenance and maintenance
intervals for your Groundsmaster machine. Refer to that
publication for additional information when servicing the
machine.

Check Hydraulic Fluid

The Groundsmaster hydraulic system is designed to op-
erate on anti--wear hydraulic fluid. The hydraulic reser-
voir located beneath the operator seat holds
approximately 7.75 U.S. gallons (29.3 liters) of hydrau-
lic fluid. Check level of hydraulic fluid daily. See Oper-
ator's Manual for fluid level checking procedure and oil
recommendations.

Relieving Hydraulic System Pressure

Before disconnecting or performing any work on the hy-
draulic system, all pressure in the hydraulic system
must be relieved. Park machine on a level surface, make
sure that PTO switch is OFF, lower cutting decks fully,
stop engine and engage parking brake. Wait for all mov-
ing parts to come to a complete stop.
System pressure in lift circuit is relieved when the cutting
decks are fully lowered.
System pressure in mow circuit is relieved when the
PTO switch is disengaged.
