Auger Direction Valve
Refer to Figure 64
A valve
toward the inlet end of the auger tube controls
the direction of auger helicoid screw rotation.This valve is
“centre off”.
To allow flow control by an operator at the outlet end, the
control handle for the valve has an extension and second
handle
.
Use this valve as the Start-Stop and Forward-Reverse
control for the auger. Set the valve to centre-Off when not
moving material at the moment.
4. With the direction control valve OFF, and
the selector valve to AUGER,
actuate the tractor auger/fan hydraulic circuit by
setting the lever to Extend.
Note: The auger circuit is reversing. The tractor circuit
may be placed into Extend or Retract. However, if
the tractor circuit placed into Extend, this provides
a consistent experience for the auger operator, and
reduces the risk of reverse fan operation.
5. Gradually move the handle away from centre-OFF.
Note the direction of auger helicoid movement.
When moving material, adjust speed as needed,
When auger operations are completed:
6. Set the auger direction control valve to centre-OFF.
7. Shut down tractor hydraulics, or set the auger/fan
circuit to Neutral or Float.
8. Set the auger/fan selector valve to FAN.
Equipment Damage Risk:
Do not make sudden or full-stroke movements of the tractor
hydraulic circuit controls with the auger circuit active. A
remote circuit capable of operating the fan has enough
hydraulic flow to damage the auger motor.
