Opener Seeding Depth
Refer to Figure 24
Side depth wheels beside the opener disks con-
trol opener seeding depth. The position of an
adjustable stop determines seeding depth.
Refer to Figure 25
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
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.
Refer to Figure 26
To adjust, move adjustment handle as shown in.
• 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.
