Traction Unit Operator's Manual

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

Check Hydraulic Fluid

The hydraulic system on Groundsmaster 3500- D ma-
chines is designed to operate on high quality hydraulic
fluid. The hydraulic system reservoir holds approxima-
tely 6 gallons (22.6 liters) of hydraulic fluid. Check level
of hydraulic fluid daily. See Traction Unit Operator's
Manual for fluid level checking procedure and hydraulic
oil recommendations.

Towing Traction Unit

In case of emergency, the Groundsmaster 3500- D can
be towed for a short distance. However, Toro does not
recommend this as a standard procedure.
1. Locate by- pass valve on hydrostat pump (Fig. 35)
o
and rotate it 90 to open the by- pass valve. This open
position should be horizontal (Fig. 36).
IMPORTANT: Do not tow the machine faster than 2 to
3 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 trailer.
2. Slowly tow machine.
3. Before starting engine, close by- pass valve by rotat-
o
ing it 90 . This closed position should be vertical (Fig.
36). Do not start engine when by- pass valve is open.
