Leveling (Side To Side)
Leveling the disc from side-to-side, involves leveling the
center section side-to-side, then leveling the wings to the
center section. This will insure that all sections are
operating evenly and consistent depth. The unit should
be level side-to-side when operating in the field.
NOTE
Do not attempt to level the center frame by only adjusting
the radius rod.
1.
To level the center section, lower the unit to the
ground, and remove the adjustable radius rod
between the main lifts on the center section.
2.
Fully raise the implement and hold the hydraulic lever
for approximately 1 minute to rephase all lift
cylinders. Then lower the implement to the ground
and fully retract the cylinders. (Note: The depth stop
will need to be adjusted out of the way to allow the
cylinders to fully retract.) The two master cylinders on
the center frame should measure 22-1/4” at the pin
centers, and should not be any visible plated shaft
showing.
3.
Lay a straight edge across the top of the frame and
measure from the top of the frame to the top of the
walking beam spindle of both center frame axles. If
the measurements are more than 1/4” different, the
cylinders will need adjusted.
4.
To adjust the cylinders, loosen the locking bolts
through the end of the cylinder clevises. Use a
wrench (on the flats behind the cylinder clevis) to turn
the cylinder rod thus extending/retracting the cylinder
clevis. Adjust the clevises equally. By turning one
cylinder out one turn and turning the other cylinder
rod in one turn will change the lift wheel
measurement approximately 1/4”.
5.
Verify that the cylinders are still fully retracted and
check the measurement from the walking beam
spindle to the top of the frame. Adjust the cylinder
rods until the measurement is within 1/4”.
6.
Retighten the locking bolts through the ends of both
cylinder clevises.
7.
With the cylinders still fully retracted, install the
adjustable radius rod between the two main lifts. This
will insure the lifts are properly timed and not binding.
The radius rod centers will be approximately 21” long
.

8.
When the center frame has been leveled
side-to-side, the wings may be leveled to the center
frame. Fully raise the implement and hold the
cylinders extended for approximately 1 minute to
again rephase the lift cylinders.
9.
Lower the implement until the disc blades are
approximately 1” above the ground. Measure the
distance from the walking beam spindle to the top of
the frame on the right center frame and right wing
. The dimension should be the same.
