2.
When setting hitch, lower lift cylinders completely.
Set the 3-point hitch or hydraulic tongue so that the
top of the tongue tube
➀
is:
46in above ground.
This is the starting point for adjustments.
Field Results Risk:
Planter must be fully lowered to field position and hitch height
must be set before making side-to-side adjustments.
If planting 1

in deep, adjust the hitch until frame
measures approximately 26in from ground to frame
at the pivots.When planting at other depths, frame
height will vary.
Note: Parallel arms should be parallel with ground or up
to 1in lower in back. Adjusting a 3-point hitch to lev-
el parallel arms may cause frame to sit higher or
lower than 26in.
4.
Check parallel arms behind the pivots to ensure that
parallel arms are parallel with ground or up to 1in
lower in back. If needed, raise or lower the 3-point to
adjust parallel arms.
5.
Once parallel arms are parallel with ground or up to
1in lower in back and 3-point is set, measure dis-
tance from ground to frame at the pivots.
Measure wings at gauge wheel. If not level with cen-
ter of frame, adjust eye bolt accordingly.
Note: Eye-bolt adjustments are easier if the planter is first
lowered to the ground to remove some of the force
on the cylinder.
