Level Planter
All frame sections must be level to maintain even plant-
ing depth. Before using the planter in the field, make sure
the planter is level side-to-side.
Periodic frame-leveling adjustments should not be nec-
essary, but if there are problems with uneven depth,
check planter levelness and follow these procedures.
Before making any adjustments be sure the lift cylinders
are re-phased and operating properly.
Complete the steps under “Bleeding Hydraulics” on
page 81, before proceeding.
Note: Level frame in planting conditions or the planter
may not produce desired results.
Refer to Figure 142
1.
Unfold the planter fully and set down. Put in field
position by lowering and pulling forward.
2. When setting hitch, lower lift cylinders completely.
Set the 3-point hitch or hydraulic tongue so that the
top of the tongue tube
is:
46in (116.8cm) above ground for YP1225, or
42in (106.7cm) above ground for YP1625.
This is the starting point for adjustments.
Refer to Figure 143
3.
If planting 1 1 ⁄
2
in (3.8cm) deep, adjust the hitch until
frame measures approximately 26in (66cm) from
ground to frame at the pivots.When planting at other
depths, frame height will vary.
Height Mis-adjustment Risk:
Planter must be fully lowered to field position and hitch height
set before making side-to-side adjustments.
Note: Parallel arms should be parallel with ground, or up to
1in (2.5cm) lower in back. Adjusting a 3-point hitch to
level 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.
Refer to Figure 144
6.
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.
