5. If the wing measurement differs from the reference
measurement, remove the pin from the rod end of the
wing-gauge-wheel cylinder. Block or support the wing
gauge wheels so the distance from the bottom of the
straight edge to the center of the wing-gauge-wheel
axle is the same as the reference measurement taken
in step 3.
6. Loosen the nuts (1) on the cylinder eye bolt as shown
in Figure 1-10. Move the eye bolt in or out until the rod
end of the cylinder can be pinned to its lug. Secure the
eye bolt by tightening the nuts.

7. Repeat steps 4, 5 and 6 for other wing section.
Level Frame Front to Rear
The front-to-rear levelness of your drill will also affect
seeding depth. If the lift-assist wheels raise the rear of the
implement higher relative to the front, the openers may op-
erate at the wrong angle. The opener bodies should run
parallel to the ground. If they do not, level the angle which
the implement runs by following these instructions.
1. Check that the lift hydraulics are bled of air and full of
oil. See Bleeding the Lift Hydraulics, page 12.
2. Turn the nuts (1) on the eye bolt on the lift-assist cylin-
der shown in Figure 1-11.
•
To raise rear of implement, move eye bolt in toward
drill.
•
To lower rear of implement, move eye bolt out.
3. Repeat for other lift-assist wheel.

Level Frame Side to Side
All frame sections must be level to maintain even seeding
depth. Before using the implement in the field, follow these
steps to make sure the implement is level side-to-side.
Periodic frame-leveling adjustments should not be neces-
sary, but if you are having problems with uneven depth,
check drill levelness and follow these procedures.
1. Check that the lift hydraulics are free of air and full of
oil. See Bleeding the Lift Hydraulics, page 12.
2. Unfold and lower the implement. Make sure the lift cyl-
inders are fully retracted, then block up or otherwise
support the frame.
3. Take a reference measurement by laying a straight
edge across the top of the two coulter mount tubes on
the center section. Measure from the bottom of the
straight edge to the center of one rockshaft-wheel axle
as shown in Figure 1-8. Because rockshaft gauge
wheels are not adjustable, all adjustments will be
made relative to this measurement.

4. Move the straight edge to one of the wings. Measure
the distance from the bottom of the straight edge to
the center of wing-gauge-wheel axle as shown in Fig-
ure 1-9.
