4-8 LEVELING (SIDE TO SIDE)

4-8.1 Leveling the Vertical Harrow 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.
4-8.2 To level the unit, verify that all tires are
properly inflated, and that the center radius
rod adjustment has been properly set. 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
rephasing lift system has been purged of air.
Lower the unit until the disc blades are ap-
proximately 1" off the ground. On the center
frame, measure the distance from the walk-
ing beam spindle to the bottom side of the
frame (See Figure 4-7). Measure the same
distance on the wing frame. The wing frames
are generally set to the same distance or
slightly higher than the center frame. Adjust-
ing the anchor at the base end of each wing
lift cylinder sets wing frame height (See Fig-
ure 4-8).
4-8.3 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 imple-
ment, lower to just above the ground, and
re-verify measurements. Repeat as neces-
sary and securely tighten the cylinder anchor
when complete.
