Press Wheel Adjustments
Opener Depth (Press Wheel Height)
Seeding depth on 3N-4010HDA is set by frame-mounted
coulter depth (if installed) and row unit depth. Whether
frame-mounted coulters are installed or not, set frame
height (page 34 or page 38) before making row unit
depth adjustments.
10HD Series press wheel height is a stop adjustment
and not a spring adjustment. It establishes a fixed
relationship between opener depth and the closed-furrow
surface at the press wheel
Refer to Figure 49
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. Initially adjust
all press wheels to the same height. Individual rows
running in tire tracks may need to be set deeper
a
.
• For more shallow seeding, slide T handles forward
toward drill.
• For deeper seeding, slide T handles backward
away from drill.
If press wheels are lifting off ground, check front-to-back
level, and increase row unit spring down force.
If press wheels are digging into ground, reduce spring
down force at the row units.
Press Wheel Spacing
Double V Press Wheel Adjustment
Refer to Figure 50
The double-V closing wheels
can be moved inward
and outward to alter how they close the seed trench and
press soil over the seed.
To move the wheels in toward the center of the trench,
remove one of the

in (6.4mm) spacer bushings
next
to the press wheel arm and position it under the head of
the hex head cap screw
.
On wider row spacings the closing wheels can be moved
outward by relocating the spacers to the inside, next to
the press wheel arm
.
a. If frame-mounted coulters are installed, adjust them for tire tracks before adjust T-handles. The coulter depth adjustment may be all
that’s required to compensate for tracks.
