Pushing or Towing Traction Unit

Using Traction Pump By−Pass Valve
In an emergency, the traction unit can be pushed or
towed for a very short distance by using the traction
pump by−pass valve.
IMPORTANT: Do not push or tow the traction unit
faster that 2 to 3 MPH (3 to 5 Km/Hr) because the hy-
draulic system may be damaged. If traction unit
must be moved a considerable distance, transport
it on a truck or trailer.
1. Remove the retainer clip from seat lock rod.
2. Raise seat and support it in upright position with seat
support rod (Fig. 6).

4. Rotate by−pass valve 90 degrees. Opening the valve
opens an internal passage in the traction pump, thereby
by−passing hydraulic oil. Because oil is by−passed,
traction unit can be moved without damaging the hy-
draulic system (Fig. 8).

IMPORTANT: Make sure that hand brake is engaged
before opening the by−pass valve.
5. Before starting engine, close by−pass valve. Do not
start engine when valve is open.
IMPORTANT: Running the machine with the by−
pass valve open will cause the hydraulic system to
overheat.
DANGER
Vehicle will roll with front wheel motors disen-
gaged. Vehicle must be on level surface or
wheels must be blocked. There is no effective
braking with wheel motors disengaged.
If towing, with front wheel motors disengaged,
Tow Bar Assembly, Toro part no. 58−7020, must
