Adjusting Disk Contact
Row unit disk blades may be sharp. Use caution when making
adjustments in this area.
Refer to Figure 102
1. Unfold the drill (page 25). Leave the row units raised.
2. Place blocking or stands under the opener
subframes.
3. Remove the bolt retaining the opener disk on one
side. Carefully remove the blade , noting how
many spacers are outside the disk and how many
are inside the disk. Do not lose the hub components
and spacers.
4. To reduce the spacing between the disks (the normal
case), move one spacer washer from the inside to
the outside.
 When installing new blades, it is generally necessary
to move outside spacers back inside after both disks
are mounted.
5. Re-assemble and check disk contact.
Disk Scraper Adjustments
Disk scrapers are optional. See page 142 ordering
information and page 165 for installation. To keep opener
disks turning freely, dirt scrapers are mounted between
disks to clean as disks rotate.
Row unit disk blades may be sharp. Use caution when making
adjustments in this area.
Refer to Figure 103
As field conditions vary, scrapers may need to be
adjusted. In damp conditions, lower scrapers. If openers
are not turning freely, raise scrapers. To adjust, loosen
bolt and move scraper as needed.
