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.

Towing Traction Unit

IMPORTANT: If towing limits are exceeded, severe
damage to the piston pump may occur.
If it becomes necessary to tow (or push) the machine,
tow (or push) in a forward direction only, at a speed
below 3 mph (4.8 kph) and for a distance less than 1/4
mile (0.4 km). The piston (traction) pump is equipped
with a bypass valve that needs to be turned 90
ing. Do not turn bypass valve when engine is running.
See Traction Unit Operator's Manual for additional tow-
ing procedures.
IMPORTANT: If the machine must be pushed or
towed in a reverse direction, the check valve in the
4WD/2WD control manifold must be bypassed. To
bypass this check valve, connect a hydraulic hose
between the reverse traction pressure test port and
the 4WD/2WD control manifold test port (G). Toro
part numbers 95- -8843 (hydraulic hose), 95- -0985
(coupler fitting) (2 required) and 340- -77 (hydraulic
fitting) (2 required) are needed for this connection.

Check Hydraulic Fluid

The Groundsmaster 4500--D and 4700--D hydraulic
systems are designed to operate on anti--wear hydraulic
fluid. The reservoir holds approximately 8.25 gallons
(31.3 liters) of hydraulic fluid. Check level of hydraulic
fluid daily.
