Fertilizer Tube Adjustment
Refer to Figure 81
On a double-shoot drill, deeper dry fertilizer placement
may be achieved by rotating the fertilizer tube
to face
forward.
This orientation is suggested only if the seed firmer is a
seed flap
. If a Keeton or Seed-Lok™ is present, fertil-
izer falls on the firmer and may be scattered rather than
placed deeper.

Opener Depth (Press Wheel Height)
Refer to Figure 82
Set opener seeding depth
by adjusting press-wheel
height .
To adjust, first raise openers slightly, then lift and slide
T handles
on top of openers Adjust all press wheels to
the same height.
• Each increment of the handle adjusts the seeding
depth by approximately 6.3mm
1 ⁄
8
in). The range is
approximately 0-8.9cm (0 to 3
1 ⁄
2
in) seeding depth.
• For more shallow seeding, slide T handles forward
toward implement.
• For deeper seeding, slide T handles backward
away from implement.
If moving the T handle backward doesn’t cause the
opener to achieve desired depth, lower the coulters by
lowering the frame height (page 81), and increase weight
transfer pressures if necessary (page 85).
If coulters are installed, set coulter depth with tool bar
height (page 81). Adjust opener depth to be 13mm (
1 ⁄
2
in)
shallower.
If no coulters are installed, adjust tool bar height
(page 81) so that opener frame runs level at desired
seeding depth.
