Wing Alignment
To check and adjust wing alignment:
1. Unfold planter, see “Unfolding the Planter” on page
24, and place a block ahead of each wing gauge
wheel. Pull planter forward against blocks to rock
frames back.
Refer to Figure 12
2.
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 (dimen-
sion A) should be 0-to-
1 ⁄
4
in ahead of inside ends
(dimension B).
3. To adjust wing alignment, shorten or lengthen eye
bolts to change the length of the wing pull bar. Adjust
eye bolts
➀
in or out until dimension A is 0 to 1 ⁄
4
in
greater than dimension B.
4. Be sure both wings are adjusted equally or the
planter will tend to pull sideways behind the tractor.
Note: Angle of wings is exaggerated for ease of clarifica-
tion.
Marker Extension
Prior to first marker use during planting, unfold each
marker side in field conditions, and check marker exten-
sion. The distance
from the mark to the centerline of
each end row unit is:
185in (470cm).
Check also that the mark left is sufficiently visible for your
soil and residue conditions.
For changes, see “Marker Adjustments” on page 41.
