Refer to Figure 41
Set opener seeding depth by adjusting handles.
To adjust, first raise openers slightly, then lift and
slide handles on top of openers. Adjust all han-
dles to the same setting.
• For shallower seeding, slide handles forward
toward drill.
• For deeper seeding, slide handles back away
from drill.
Press Wheel
Refer to Figure 42
Press wheels are attached to each opener body.
The press wheels close the seed trench and gen-
tly press soil over seed.
An adjustable spring in the press-wheel mecha-
nism creates the down pressure needed to close
the seed trench. The amount of force needed will
vary with field conditions.
To adjust, move adjustment handle.
• For less down pressure, move handle forward
toward drill.
• For more down pressure, move handle back
away from drill.
NOTE: Increased press wheel spring force
may require increased opener down force to
maintain depth.
NOTE: The factory setting on the press wheel
is staggered to achieve optimum residue flow.
Refer to Figure 43
If you want to adjust press wheels from staggered
to even, remove 5/8 inch bolt (1), lock washer (2)
and nut (3). Reinstall spacer (4), press wheel (5)
and hardware to the other hole location.
