Opener Depth (Press Wheel Height)
Seeding depth on NTA3010 and NTA3510 is set by
coulter depth and row unit depth. Set coulter depth
before making row unit depth adjustments.
10 Series press wheel height is a stop adjustment and
not a spring adjustment. It establishes a fixed
relationship between opener depth and closed-furrow
surface at the press wheel
Refer to Figure 57
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.
• For more shallow seeding, slide T handles forward
toward implement.
• For deeper seeding, slide T handles backward
away from implement.
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.
Harrow Adjustment
Figure 58 shows a successful harrow position for no-till
conditions. Because of different soil moisture, trash
levels and trash types, you may need to reposition the
tube frame or tines. Initially position the frame and tines
as shown, then re-adjust as necessary.
