Wing Alignment
To check and adjust wing alignment:
1. Unfold planter. See “Unfolding the YP3025A
Planter” on page 25.
2. Set tongue height (page 21).
Lower planter. Pull forward.
Refer to Figure 128 and Figure 129
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
in (0-to-6mm) 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
in (6.4mm) 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.
