35 Adjustments
Refer to Figure 28
Set seeding depth by adjusting handles. To ad-
just, first raise row-units slightly, then lift and slide
handles on top of row-units. Adjust all handles to
the same setting.
• For shallower seeding, slide handles forward
toward planter.
• For deeper seeding, slide handles back away
from planter.
Press Wheel
Refer to Figure 29
Press wheels are attached to each row-unit 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 planter.
• For more down pressure, move handle back
away from planter.
NOTE: Increased press wheel spring force may
require increased row-unit down force to maintain
depth.
NOTE: The factory setting on the press wheel is
staggered to achieve optimum residue flow.
Refer to Figure 30
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.
