Disc 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 turning 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 after 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 adjustment
stud. Refer to Figure 19.
Tighten jam nut to maintain idler position.
Note: Do not over-tighten chains. To do so will cause
excessive wear.
