Wing Leveling, Inboard End
Wing leveling check/adjustment is required prior to first
use of the YP3010HDP/3020P/3025, and periodically
thereafter, for example, if soil conditions change dramati-
cally.
Before performing this operation:
• Lower unfolded planter in soil. Pull forward until gauge
and caster wheels are in normal planting position.
• Row unit coulter/planting depths, and row unit
down-pressures must all be equal.
• Check center section height and level (page 21).
Refer to Figure 123
1.
Measure the height of the inboard end of each wing,
directly under the wing flex pivot.
2. Compare this height to that of the center section
obtained at step 1 on page 92.
3. If the heights differ by more than 1in (2.5 cm), 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.
Note: Any unevenness in ground that tilts the wings or
center section causes the inner wing ends to move
up or down slightly with respect to the center frame.
Wing Leveling, Outboard End
Refer to Figure 122 on page 92 and Figure 124
1.
Measure from the bottom of the wing tool bar to the
ground at the outer end of each wing.
2. Compare to the measurement at the outer end of the
center tool bar, at the wing pivot location. All mea-
surements should be identical, and close to
26in (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 .
