operated.
PUSHING OR TOWING THE TRACTION
UNIT
In an emergency, the traction unit can be pushed or towed for a
very short distance. However, Toro does not recommend this as
standard procedure.
IMPORTANT: Do not push or tow the traction unit faster
than 2 to 3 mph (3 to 4.8 km/hr) because the transmission
may be damaged. If the traction unit must be moved a con-
siderable distance, transport it on a truck or trailer.
Whenever the traction unit is pushed or towed, the by-pass
valve must be open.
1. Reach under the traction unit and turn the by-pass valve
1
(Fig. 14) ⁄ to 1 turn counterclockwise. Opening the valve
2
opens an internal passage in the transmission, thereby
bypassing the transmission oil. Because fluid is by-passed,
the traction unit can be moved without damaging the trans-
mission.
2. Before starting the engine, close the by-pass valve by rotat-
ing it clockwise until it is securely seated. Do not exceed
5 to 8 ft-lb (7–11 N-m). Do not start the engine when the
valve is open.
IMPORTANT: Running the machine with the by-pass valve
open will cause the transmission to overheat.
OPERATING CHARACTERISTICS
Practice driving the GROUNDSMASTER 325-D because it has
a hydrostatic transmission and its characteristics are different
than many turf maintenance machines. Some points to consider
when operating the traction unit, cutting unit or other implement
are the transmission, engine speed, load on the cutting blades or
other implement components, and the importance of the brakes.
To have enough power for the traction unit and implement
while operating, regulate the traction pedal to keep the engine
rpm high and constant. A good rule to follow is; decrease
ground speed as the load on the implement increases; and
increase ground speed as the load decreases.
Therefore, let the traction pedal move backward as engine rpm
