Selector Valve
This valve is located inside the right rear corner of the
mainframe. It selects between auger and fan.
3.
Move selector valve handle from Fan to Auger.
Do not operate this valve with the hydraulic circuit energized.
Unexpected auger or fan operation can result.
Do not use this valve as the Start-Stop control for the auger.
Operate the valve with the tractor hydraulic circuit off, or
set to neutral or float. The handle has two positions.
Auger Selector Valve Positions
Auger Direction Valve
A valve
toward the inlet end of the auger tube controls
the direction of auger helicoid screw rotation.This valve is
“center 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 center-Off when not
moving material at the moment.
4.
With the direction control valve OFF, and
the selector valve to AUGER,
activate the tractor auger/fan hydraulic circuit by
setting the lever to Extend.
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 center-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 center-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.
Handle Forward: Auger (make sure Auger control is in
center-off position before moving handle to
).
Handle Rear: Fan-enable (make sure circuit is off before
moving handle to
).

Do not make sudden or full-stroke movements of the controls
with the circuit active. A circuit capable of operating the fan
has enough hydraulic flow to damage the auger motor.
