Landoll 9650 Field Cultivator - Manual (Page 73)

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 4-7.) Adjust the
lift arms at the front of the Field Cultivator center
frame until the spindle heights are the same.
NOTE
The lift arm nuts will be approximately flush with the end
of the lift arm adjustment rod on the center frame.
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 lift arm nuts when complete.
4. Measure the same distance on the wing frame. The
wing frames are generally set 1/2” 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.

Gauge Wheels
1. The Field Cultivator is equipped with castering gauge
wheels at the outer front corners of each wing. These
gauge wheels are used to limit depth of the wings,
and prevent gouging and buckling of wing frames.
2. Gauge wheels are not intended to carry the wing, but
prevent excessive depth. Adjust the wheels to carry
some weight, but not enough hold the wing from
reaching operating depth set with the main lift
hydraulics.
3. To adjust the gauge wheel depth, loosen and adjust
the nuts on each side of the gauge wheel cross (See
Figure 4-8.) A wrench is provided on the implement
for this adjustment (See Figure 4-6.) All other
connections should remain tight. Securely tighten the
adjusting nuts when complete. All gauge wheel
assemblies should be set the same. Verify
adjustment by measuring the length of the bolt
centers of the gauge wheel adjustment rod.
