Pushing Or Towing The Traction Unit; Operating Characteristics - Toro Groundsmaster 328-D 30630 Operator's Manual

take-off lever is disengaged and the traction pedal is
released, it is strongly recommended that you stop the
engine before dismounting from the seat.
To check interlock switch operation:
1. Drive the machine slowly to a large, relatively
open area. Lower the cutting unit, stop the engine
and apply the parking brake.
2. Sit on the seat. Move the power take-off lever to
the ON position. With the traction pedal in
neutral, try to start the engine. The engine should
not crank. If it does, there is a malfunction in the
interlock system that should be corrected before
beginning operation.
3. Sit on the seat. Move the power take-off lever to
OFF and depress the traction pedal. Try to start
the engine. The engine should not crank. If it
does, there is a malfunction in the interlock
system that should be corrected before beginning
operation.
WARNING
Do not operate the machine without an
implement unless the power take-off drive
shaft is also removed.
4. Sit on the seat and start the engine. Disengage
the parking brake. Rise from the seat and move
the power take-off lever to ON. The engine
should stop within 2–3 seconds. If it doesn't,
there is a malfunction in the interlock system that
should be corrected before beginning operation.
5. Engage the parking brake. Depress the traction
pedal while the engine is running and the power
take-off lever is disengaged. The engine should
stop within 2 seconds. If the engine stops, the
switch is operating correctly. If it doesn't, there is
a malfunction in the interlock system that should
be corrected before beginning operation.
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 no push or tow the traction unit faster
than 2 to 3 MPH (3 to 4.8 km/h) because the
transmission may be damaged. If the traction unit
must be moved a considerable distance, transport it on
a truck or trailer. Whenever the traction unit is pushed
or towed, the bypass valve must be open.
1. Reach under the traction unit and turn the bypass
valve (Fig. 13)
Opening the valve opens an internal passage in
the transmission, thereby bypassing transmission
oil. Because fluid is bypassed, the traction unit
can be moved without damaging the
transmission.

1. Bypass valve
2. Before starting the engine, close the bypass valve
by turning it clockwise until it is securely seated.
Do not exceed 5 to 8 ft.-lb. (7 to 11 N•m). Do not
start the engine when the valve is open.
Important
Running the machine with the bypass
valve open will overheat the transmission.

Operating Characteristics

Practice driving the machine 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.
