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, scrapers may
need to be adjusted. In damp conditions, scrapers
may need to be lowered. If openers are not turn-
ing freely, scrapers may need to be raised.
To adjust scrapers, loosen 3/8 inch bolt shown in
Figure 18 and move scraper as needed.
Gauge Wheel Idler Adjustment
Located inside the left hand gauge wheel arm is
two idler sprockets which should be readjusted af-
ter the first 100 acres of drill use. From then on,
readjust at the beginning of each season.
To adjust, move front idler sprocket on top of chain
down by loosening jam nut and screwing in ad-
justment stud. Refer to Figure 19.
Retighten jam nut to maintain idler position.
NOTE: Do not over-tighten chains. To do so will
cause excessive wear.
