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
adjusted. 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 3/8-
inch bolt as shown in Figure 3-1 and move scraper as
needed.

Drive Clutch
The main drive clutch on your drill is a mechanical-
release, jaw-style design. You may need to adjust the
clutch for proper engagement and disengagement.
When properly adjusted, the cam plates will disengage the
clutch jaws completely when the drill is raised. When low-
ered in field position, clutch jaws should be engaged.
To adjust, loosen bolts on clutch tab (1). Slide tab forward
or back to change point at which cam plates (2) meet.
When satisfied with adjustment, retighten bolts on clutch
tab.

Drive Train Operation
Check all chain idlers at beginning of each season for
proper adjustment. Check that each idler is taking up
excess chain slack. On fertilizer or native grass drills,
remove left end panel to inspect drive chain and idler.
After first 100 hours of use and at beginning of each sea-
son, readjust idler sprocket in left wheel arm. To access
idlers, remove access door. See Figure 3-3.

Access Door
To adjust idler sprocket, refer to Figure 3-4. Move top idler
sprocket (1) down into chain by loosening jam nut and
screwing in adjustment stud (2). Retighten jam nut to
maintain idler position.

Idler Sprocket Adjustments
NOTE: Do not overtighten chains. Overtightening chains
will cause excess wear on idlers and drive components.
Be sure chain is installed with the chain connector link re-
tainer towards the centerline and the clip opening (split
end) faces the opposite way of the chain travel.
