Disk Scraper Adjustment
To keep the opener disks turning freely, dirt scrapers are
mounted between the disks to clean as the disks rotate.
As field conditions vary, the scrapers may need to be ad-
justed. In damp conditions, the scrapers may need to be
lowered. If openers are not turning freely, the scrapers
may need to be raised. To adjust the scrapers, loosen the
3/8-inch bolt as shown in Figure 3-10 and move scraper as
needed.
