Opener Down Pressure
Refer to Figure 14
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 15
To adjust down pressure, use adjustment tool stored
under walkboard. Position tool in hole on spring
mounting plates, and pull down as shown. Move
adjustment cam to the new setting.
Refer to Figure 16
Minimum and maximum settings are indicated by
position of adjustment cam.
