Wing Alignment
To check and adjust wing alignment:
1. Unfold Planter. See “
Unfolding the YP3025A
Planter ” on page 26.
2. Set tongue height (page 22).
Lower Planter. Pull forward.
Refer to Figure 133 and Figure 134
3. Select a common reference point that is easy to
access at the wing-end and center section end row
units, such as the back of the press wheel assembly
. On a twin-row Planter, align using only the rear
units.
4. Check for proper alignment by running a string line
across back of Planter toward outer ends of wings.
For proper alignment, outside ends of wings
should be 0-to-
1
/
4
inch (0-to-6.4 mm) ahead of inside
ends of wings at center section .
5. To adjust wing alignment, shorten or lengthen eye
bolts to change the length of the wing pull bar.
Adjust eye bolts in or out until dimension is
0-to-
1
/
4
inch (6.4 mm) greater than dimension .
6. Be sure both wings are adjusted equally or the
Planter will tend to pull sideways behind the tractor.
Measure length of both pull bars, pin to pin, and set
the same.
