Wing Alignment
To check and adjust wing alignment:
1. Unfold planter. See “
Unfolding the YP2425A
Planter ” on page 26. Lower planter. Pull forward.
Refer to Figure 145 and Figure 146
2. 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.
3. 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
inches ahead of inside ends of
wings at center section .
4. 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
inches (6.4 mm) greater than dimension .
5. Be sure both wings are adjusted equally or the
planter will tend to pull sideways behind the tractor.
