4.6 CONTROLS
Before starting to operate the extractor to unload a
bag, all operators should familiarize themselves with
the location and function of the controls.
1.
Raise/Lower:
This 3 position spring-loaded to center-neutral
lever controls the flow of oil to the frame cylin-
ders. Pull on the lever and hold to extend the
cylinders and raise the gathering head. Push
and hold to retract the gathering head into its
working position. Release the lever and it will
return to its center-neutral position.
2.
Discharge Auger Swing:
This 3 position spring-loaded to center-neutral
lever controls the flow of oil to the discharge
auger swing hydraulic drive motor. Pull on the
center lever and hold to swing the auger to the
right. Push and hold to swing to the left. Release
the lever and it will return to its center-neutral
position.
3.
Steering:
This 3 position spring-loaded to center-neutral
lever controls the flow of oil to the drive wheel
steering circuit. Pull on the lever and hold to
turn the wheels to the right. Push and hold to
turn them to the left. Release the lever and it
will return to its center-neutral position.
4.
Roller:
This 3 position spring-loaded to center-neutral
lever controls the flow of oil to the bag roller drive
system. Pull on the lever and hold to pull the bag
through the rollers. Push and hold to back the
bag out of the rollers. Release the lever and it
will return to its center-neutral position and the
rollers will stop.
5.
Wheel Drive:
This pop valve controls the flow of oil to the mo-
tors on the wheel drives. Pull on the valve and
place it into detent to power the drives and move
the Extractor into the bag. Push and place into
detent to stop the wheel drives.

6.
Flow Control Valve:
This manually-set flow divider allows the opera-
tor to set the flow through the hydraulic circuit
from 0% to 100% by dumping the excess flow
back to the tractor. A scale on the face of the
valve is numbered from 0 to 10 to define the
percent flow from 0% to 100% flowing into the
circuit. Loosen the lock and move the pointer
arm to the desired position. Tighten the lock bolt.
Adjust in small increments as a small change
can result in a large change to moving speed.
7.
Hydraulic Controls:
Use only the tractor hydraulic circuits that are
designed with a detent. Place the lever in detent
to provide a steady flow of oil to the circuits.
NOTE
When hooking the machine to the trac-
tor, place the circuit in detent. Pull on
the Raise/Lower control lever. It should
lower the gathering head frame to the
ground for correct machine operation. If
it does not, place control in neutral and
reverse hose hook-up or move the lever
to the other side to reverse the direction
of oil flow.
