Disk Scraper Adjustments

mounted between disks to clean as disks
rotate.Standard 10 Series row units include a
double-disk slotted scraper. A carbide scraper is
available (see “Seed Firmers” on page 60).
Refer to Figure 54
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.
