Set Wing Pressure:
1.
Set wing pressure by tapping SCV (3) until gauge reads desired pressure.
Typical settings are 0-300 psi for previously tilled/soft ground and 300-500 psi
for untilled/hard ground. If desired pressure is exceeded, place SCV in float
and reset pressure. DO NOT EXCEED 500 PSI!
Wing Pressure Gauge –
Set to 300-500 PSI
2.
Turn Selector Valve to “FIELD”
operation.
Fully extend rear packer cylinders (1).
Turn SCV to 100% flow.
Raise machine (2) and wings (3) so it is
no longer resting on the wing lock pins.
Remove the rear cylinder safety stop,
front stops and wing lock pins.
Unfold wings (3) and put hydraulic remote into float position.
Raise rear axle (2) so implement is resting on the packer.

3.
Raise outside gauge wheels off the ground to
their highest set points. (The gauge wheels
need to be lifted so they do not interfere with
correctly setting the depth control.) See
‘Gauge Wheel Setting’ below.
For shallower working depth, turn the handle
clockwise.
For deeper working depth, turn the handle
counterclockwise.
NOTE: The machine will also need to be
leveled by either adding, or removing stops to
the front hydraulic cylinder.
Depth Control Gauge

Shallower – clockwise.
Deeper - Counterclockwise
Depth Setting:

2.
For shallower working depth of the machine, add stops.
For deeper working depth of the machine, remove stops.
Tracking:
1.
2.
If machine is tracking to the right, add more stops to the front cylinder.
If machine is tracking to the left, remove stops from the front cylinder.
NOTE: Add or remove stops to the front cylinder until the machine
tracks straight.

Lower the machine to the predetermined set depth into the ground and start tilling.
Run machine slowly (5-6 mph) at set depth.
Adjust gauge wheels so wings are level with center frame. DO NOT LIFT
MACHINE OUT OF GROUND!
Turn the turnbuckles to lower the gauge wheels to the ground.
NOTE: The tires should only support the machine on the ground in case of
obstructions and following the contour of the field. The wheels should not lift the
wings when in operation. The gauge wheels keep the machine steady and
maintain the desired working depth. The wheels only have a sensing and
supporting function.
NOTE: The gauge wheel should not be set until the depth setting has been
completed.
Increase operation to desired speed (8-10 mph) and make fine adjustments as
necessary.
Depth Gauge
Gauge Wheel Setting:
Stop machine and lower machine to set depth (1).
Turn Selector Valve to “ROAD” mode.
Lower transport axle to ground (2).
Extend front hitch cylinder completely (1).
Fold wings (3).
Insert rear cylinder safety stop, front stops and wing lock pins.
Remove soil buildup from machine.

Troubleshooting:
Problem
Cause
Solution
Machine does not track straight.
Machine is not level front to back
Entire machine plugs when running.
Ground speed too slow; working depth too
deep.
Wings not running level.
Tractor SCV not set to 100%; excessive soil
buildup on machine.
Packer is not being retracted for transport.
Adjust Hitch Offset. Verify all cylinders stop
moving before SCV returns to neutral
Increase ground speed up to 10 mph.
Reduce tillage depth.
Reduce wing pressure, adjust gauge wheels.
Set SCV to 100%.
Remove soil from
machine frame.
Retract rear packer using transport valve.
Inspect packers for bent, flattened, fractured
or broken tongues.
Wings plug when running.
Machine lifts slow.
Packer tongues failing on center of
machine.
