Disk Scraper Adjustments
Sharp Object Hazard:
Row unit disk blades may be sharp. Use caution when making
adjustments in this area.
Refer to Figure 39
Disk scrapers are optional. To keep opener disks turning
freely, dirt scrapers are mounted between disks to clean
as disks rotate.
As field conditions vary, scrapers may need to be
adjusted. In damp conditions, lower scrapers. If openers
are not turning freely, raise scrapers. To adjust, loosen
bolt and move scraper as needed.

Sharp Object Hazard:
Row unit disk blades may be sharp. Use caution when making
adjustments in this area. To adjust the Keeton

Seed Firmer Adjustment
The optional Keeton
®
Seed Firmer is an engineered
polymer shape that slides down the seed trench. It traps
seeds as they exit the seed tube and firms them into the
bottom of the "V".
Refer to Figure 40
The Firmer is provided with a preset tension which is
recommended for using the first year. The tension screw
can be tightened in subsequent years according to your
needs. Firmers should provide just enough tension to
push seeds to the bottom of the trench.
