Emergency Operation
Emergency Hydrostatic Bypass Valve
Should it be necessary to move the machine when the engine is not operable, the emergency
bypass valve, located on the hydrostatic pump, must be opened (see Figure 10.3).
This valve is located on the hydrostatic pump and painted red for ease of identication, in
the engine compartment. (See Figures 5.5 and 10.3 for location). To open the bypass valve,
rotate it two turns counter clockwise using the adjustment tool (Part No. C4-00157 or 84-
05870) supplied strapped to the suction hose.

Notes:
• This system is to be used ONLY when pushing or pulling the machine
SLOWLY.
• The bypass valve must be FULLY closed for normal operation.
• Disconnect the drive shafts for extended towing distances.
• Fast towing must not be done.
• Always close the valve once the machine is moved to the desired location.
Re-attach the bypass tool to the hydraulic hose.
