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. Locate two (2) by–pass valves on transmission (Fig.
8). 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.
2. Slowly push machine.
3. Before starting engine, tighten both by–pass valves
to close them. Torque valves from 62 to 79 in–lb (7 to
9 N–m). Do not start engine when by–pass valves are
open.

Relieving Hydraulic System Pressure

Before disconnecting or performing any work on the
Groundsmaster 7200 and 7210 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 (or im-
plement) lowered and off. Turn key switch to OFF and
allow engine to stop. If machine is parked on an incline
or slope, pressure in the traction circuit WILL NOT be re-
lieved.

1. Transmission
To relieve hydraulic pressure in lift circuit, fully lower the
cutting deck (or implement) onto solid blocks. Turn key
switch to OFF and allow engine to stop. Make sure that
after lowering, the cutting deck (or implement) is not be-
ing supported by the lift cylinder.
