Opener Down Pressure
Refer to Figure 13
Opener springs provide the down pressure necessary
for opener disks to open a seed trench. The springs
allow the openers to float down into depressions and up
over obstructions.
You can adjust down pressure individually for each
opener. This is useful for penetrating hard soil and
planting in tire tracks.
Use enough down pressure to cut the seed trench and
maintain proper soil-firming over seed. Excessive
opener down force will lead to premature wear on
opener components.
Refer to Figure 14
To adjust down pressure, use adjustment tool stored
under walkboard. Position tool in hole on spring
mounting plates, and pull down as shown. Move the
adjustment cam to the new setting.
Refer to Figure 15
Minimum and maximum settings are indicated by
position of adjustment cam.
 NOTE: Install the chain connector link so that the
clip opening (split end) faces the opposite of the
chain travel with the retainer towards the centerline
of the opener.
