Wing Leveling
Wing Leveling, Inboard End
Wing leveling check/adjustment is required prior to first
use of the YP24, and periodically thereafter, for example,
if soil conditions change dramatically.
Before performing this operation:
• Check center section height and level (page 21).
• Row unit coulter/planting depths, and row unit
down-pressures must all be equal.
5. Measure the height of the inboard end of each wing,
near the wing flex pivot (location
in Figure 14).
6. Compare this height to that of the center section
obtained at step 4 on page 22.
7. If the heights differ by more than 1 inch, check them
again after leveling the wing ends. If they still differ,
the thrust washers in the wing pivots may be worn
and in need of replacement
Wing Leveling, Outboard End
Refer to Figure 15 and Figure 16
1.
Measure from the bottom of the wing tool bar to the
ground at the outer end of each wing (location
in
Figure 15).
2. Compare to the measurement at the outer end of the
center tool bar, at the wing pivot location. All
measurements should be identical, and close to
26 inches (66 cm).
3. If measurements do not match, loosen upper gauge
wheel lock nut
, and adjust eyebolt link length with
adjuster nut .
4. If adjustments are needed on either side, re-check
the other side after each adjustment, and re-adjust it
as needed.
5. Once level, tighten the lock nut .
