OPERATION AND MAINTENANCE
4-7
Leveling (Side to Side)
1. Leveling the Field Cultivator side-to-side involves
leveling the wing frames to the center frame. The unit
should be level side-to-side when operating in the
field.
2. To level the unit, verify that all tires are properly
inflated. 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. Lower the implement
until the sweeps are approximately 1” off the ground.
On the center frame, lay a straight-edge across the
top of the frame, and measure the distance from the
walking tandem spindle to the top side of the frame of
both walking tandems
See Figure 4-8 . Adjust the lift
arms at the front of the Field Cultivator center frame
until the spindle heights are the same.
NOTE
The lift arm adjustment rods on the center frame will
extend approximately 1” from the forward lift arm nut
See
Figure 4-7 .
3. An adjusting wrench is provided to make this
adjustment. It may be necessary to lower the Field
Cultivator to the ground and relieve weight on the lift
arms 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 1-3/4” hex nuts when complete.

4. Measure the same distance on the wing frame. The
wing frames are generally set 1” higher than the
center frame due to difference in tire diameter.
Adjusting the lift arm at the front of each wing frame
sets wing frame height.
