Leveling Frame Side-to-Side
45-Foot Drill
Since the dual gauge wheels on frame sections three and
four are not adjustable, make all adjustments with these as a
reference.
!
WARNING!
You may be severely injured or killed by being crushed from a
falling implement. Always have the frame sufficiently blocked
up when working on implement.
1. Check that the lift circuit is free of air and full of oil. Re-
fer to Bleeding the Hydraulics, page 10.
2. Hydraulically lower the entire implement frame. Fully
retract all gauge-wheel cylinders. Block up or otherwise
safely support the implement frame.
3. Take a reference measurement off one dual gauge-
wheel as show in Figure 2-7. Lay a straight edge
across at least two tubes of frame section three or
four. Extend the straight edge out over the axle. Mea-
sure the distance from the bottom of the straight edge
to the center of the dual gauge-wheel axle.
Figure 2-7
Reference Measurement
4. Move the straight edge out to the first frame section.
Lay the straight edge across at least two frame tubes.
Extend the straight edge over the non-castored,
gauge-wheel axle. Measure the distance from the bot-
tom of the straight edge to the center of the axle. If the
dimension is the same as the reference measure-
ment, no adjustment is necessary. Proceed to step 7.
5. If the wing measurement differs from the reference
measurement, unpin the gauge-wheel arm. Position
and support the arm to match the reference measure-
ment.
6. Swing the cylinder down and adjust the eye-bolt until
the pin holes line up. Secure the eye bolt with the jam
nut and repin the cylinder to the gauge-wheel arm.
See Figure 2-8.

Eye-Bolt Adjustment, Non-Castored Gauge Wheel
7. Move the straight edge so it lies over the castored
gauge-wheel axle. Adjust the eye bolt at the base of
the cylinder (see Figure 2-9) until the center of the axle
is about 1/2-inch higher than the reference measure-
ment. Secure eye-bolt by tightening the jam nuts.

8. Repeat steps 5, 6 and 7 for sixth frame section.
9. Make sure all cylinders are securely pinned.
10. With the drill on level ground, note where the frame
sections three and four hinge. If the sections bow at
their hinge point, adjust the cart sling so the center of
the machine is level during field operation. To adjust:
c. Lower the implement until all weight is on the
openers.
d. Unpin the sling from the cart. Loosen the jam nut
shown in Figure 2-10.
•
To raise center of frame, turn the threaded link
clockwise.
•
To lower the center, turn link counterclockwise.
