Level Planter
All frame sections must be level to maintain even
planting depth. Before using the planter in the field, make
sure the planter is level side-to-side.
Periodic frame-leveling adjustments should not be
necessary, 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 93, before proceeding.
Note: Level frame in planting conditions or the planter
may not produce desired results.
Refer to Figure 126
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:
106.7 cm (42 inches) above ground for YP1630F.
This is the starting point for adjustments.
Refer to Figure 127
3.
If planting 3.8 cm (1
1
⁄
2
inches) deep, adjust the hitch
until frame measures approximately 26 inches
(66 cm) from ground to frame at the pivots. When
planting at other depths, frame height will vary.
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 2.5 cm (1 inch) lower in back. Adjusting a 3-point
hitch to level parallel arms may cause frame to sit
higher or lower than 26 inches.
4.
Check parallel arms behind the pivots to ensure that
parallel arms are parallel with ground or up to 2.5 cm
(1 inch) 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
2.5 cm (1 inch) lower in back and 3-point is set,
measure distance from ground to frame at the pivots.
Refer to Figure 128
6.
Measure wings at gauge wheel. If not level with
center 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.
