Disk Scraper Adjustment
Refer to Figure 16
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 and move
scraper as needed.
Gauge Wheel Idler Adjustment
Refer to Figure 17
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.
Retighten jam nut to maintain idler position.
NOTE: Do not over-tighten chains. To do so will
cause excessive wear.
Drive Clutch
Refer to Figure 18
The main drive clutch on your drill is a mechani-
cal-release, jaw-style design. You may need to
adjust the clutch for proper engagement and dis-
engagement.
When properly adjusted, the cam plates will dis-
engage the clutch jaws completely when the drill
is raised. When lowered in field position, clutch
jaws should be engaged.
To adjust, loosen bolts on clutch tab. Slide tab for-
ward or back to change point at which cam plates
meet. When satisfied with adjustment, retighten
bolts on clutch tab.
