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 by a fall-
ing 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
support the implement frame.
3. Take a reference measurement from the top of the im-
plement frame to the center of one dual gauge-wheel
axle as show in Figure 2-7, page 12. Lay a straight
edge across at least two tubes of frame section three
16569
or four. Extend the straight edge out over the axle.
Measure the distance from the bottom of the straight
edge to the center of the axle.
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 out 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 (Fig-
ure 2-8) until the pin holes line up. Secure the eye bolt
with the jam nut and repin the cylinder to the gauge-
wheel arm.
7. Repeat steps 5 and 6 for implement section four.
8. Make sure that all cylinders are securely pinned.
9. 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:
a. Lower the implement until all weight is resting on
the openers.
b. Unpin the sling from the cart.
c. Loosen the jam nut shown in Figure 2-10, page
13.
•
To raise the center of the frame, turn the thread-
ed link clockwise.
•
To lower the center, turn the threaded link coun-
terclockwise.
d. When satisfied with adjustment, tighten jam nut
and repin sling to cart. Recheck levelness and re-
adjust as necessary.
