OPERATION AND MAINTENANCE

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 measurement s 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

24” long (See Figure 4-7.)

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

(See Figure 4-8.) The dimension should be the

same.

NOTE

If the tire size is different on the center than the wing, the

cylinders will need to be adjusted differently. A 2” taller

tire on the center will require the wing spindle-to-frame

height to be 1” greater than the center frame.
