General Information

Operator's Manual

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

Pushing Traction Unit

In case of emergency, your Groundsmaster can be
pushed for a very short distance. However, Toro does
not recommend this as a standard procedure.
1. Make sure that engine is not running.
2. Locate two (2) bypass valves on transmission (Fig.
1). Loosen (rotate counterclockwise) both of the valves
from one (1) to two (2) turns.
IMPORTANT: Do not push the machine faster than
2 mph because the drive system may be damaged.
If machine must be moved a considerable distance
(more than a few feet), transport it on a truck or trail-
er.
3. Slowly push machine.
4. Before starting engine, tighten both bypass valves to
close them. Torque valves from 62 to 79 in- -lb (7 to 9
N- -m). Do not start engine when bypass valves are open
or transmission damage will occur.

Relieving Hydraulic System Pressure

Before disconnecting or performing any work on the
Groundsmaster 360 hydraulic system, all pressure in
the hydraulic system must be relieved.
To relieve hydraulic pressure in the traction circuit, park
machine on a level surface with the cutting deck lowered
and off. Turn ignition switch to OFF and allow engine to
stop. If machine is parked on an incline or slope, pres-
sure in the traction circuit WILL NOT be relieved.
To relieve hydraulic pressure in lift circuit, fully lower the
cutting deck onto solid blocks. Turn ignition switch to
OFF and allow engine to stop. Make sure that after low-
ering, the cutting deck is not being supported by the lift
cylinder.

1. Transmission
To relieve hydraulic pressure in the steering circuit, park
machine on a level surface with the cutting deck lowered
and off. Turn ignition switch to OFF. After engine has
come to a complete stop, rotate steering wheel in both
directions.
Hydraulic pressure in the PTO circuit is relieved when
the ignition switch is turned to OFF.
If machine is equipped with optional hydraulic kits (e.g.
Quick Attach System), make sure that attachments are
fully lowered and supported. Then, with the engine
stopped, turn the ignition switch to RUN and move the
hydraulic kit switches to all switch positions. As hydrau-
lic solenoids are energized, circuit pressure will be re-
lieved.
