OPERATION AND MAINTENANCE

4. Leveling the Disc side-to-side involves leveling the
wing frame to the center frame. The unit should be
level side-to-side when operating in the field.
5. To level the unit:
a. Verify that all tires are properly inflated, and that
the center radius rod adjustment has been
properly set.
b. With the implement unfolded, raise the unit to
fully extend the lift cylinders. Continue to hold the
tractor lever 30-60 seconds to insure that the
cylinders are fully extended and the rephasing lift
system has been purged of air.
c. Lower the unit until the disc blades are
approximately 1” off the ground.
d. On the center frame, measure the distance from
the welded tube in the walking beam to the top
side of the frame
( See Figure 4-9. ).
e. On the wing frame, measure the distance from
the welded tube to the top side of the wing frame
( See Figure 4-10. ).
f. The wing frames are generally set to the same
distance or slightly higher than the center frame.
The 7550-40’ requires adding 1” from to center
frame measurement for the wings. The 7550-45’
requires adding 1/4” to the center frame
measurement for the wings
( See Figure 4-10. ).
NOTE
In certain conditions it may be necessary to raise the
inner wings another 1/2” or so to keep them level.
g. Adjusting the anchor at the base end of each
wing lift cylinder sets wing frame height
( See
Figure 4-11. ).
6. An adjusting wrench is provided to make this
adjustment. It may be necessary to lower the wing to
the ground and relieve weight on the cylinder anchor
to make this adjustment. If required, fully raise the
implement, lower to just above the ground, and
re-verify measurements. Repeat as necessary and
securely tighten the cylinder anchor when complete.
