Pushing or Towing the
Machine
In an emergency, the machine can be moved by actuating the
bypass valve in the variable displacement hydraulic pump and
pushing or towing the machine.
Important:
Do not push or tow the machine faster than
3-4.8 km/h (2-3 mph) because internal transmission
damage may occur. The bypass valve must be open
whenever the machine is pushed or towed.
1.
The bypass valve is located on the left side of the
hydrostat (Figure 32). Rotate the bolt 1–1/2 turns to
open and allow oil to bypass internally. Because fluid
is bypassed, the machine can be moved slowly without
damaging the transmission.

2.
Close the bypass valve before starting the engine.
However, do not exceed 7-11 N-m. (5-8 ft.-lb) torque
to close the valve.
Important:
Running the engine with the bypass
valve open will cause the transmission to overheat.
Jacking Points
Note:
Use jack stands to support the machine when required.
•
Front—rectangular pad, under the axle tube, inside each
front tire (Figure 33).
