Opener Down Pressure
To adjust down pressure on individual openers that run in
tire tracks, change opener-spring length. To increase
down pressure, loosen the jam nut at lower end of opener
spring, then turn flange nut. See Figure 3-3. Each 6 mm
(1/4-inch) turn adds about 6 kg (13 pounds) of pressure.
After adjusting flange nut, tighten jam nut.

Disk Scraper Adjustment
To keep opener disks turning freely, dirt scrapers are
mounted between disks to clean as the disks rotate. As
field conditions vary, you may need to adjust the scrapers.
To adjust, loosen 3/8-inch bolt shown in Figure 3-4 and
raise or lower scraper as needed.

inch) could cause opener damage.
