Opener Seeding Depth
Refer to Figure 24
Side depth wheels beside the operner disks control
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 handles 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 26
Press wheels are attached to each opener body. The
press wheels close the seed trench and gently press
soil over seed.
An adjustable spring in the press-wheel mechanism
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.
