Disk Blade Adjustments
Opener disc angle and stagger is not adjustable, but
disc-to-disc spacing is, and may need attention as discs
experience normal wear. Spacers will need to be reset
when blades are replaced.
Refer to Figure 102
The ideal spacing causes the blades to be in contact for
about one inch. If you insert two pieces of notebook
paper between the blades, the gap between them should
be 0-to-4.4cm (0 to 1.75in).
If the contact region is significantly larger or smaller (or
there is no contact at all), it needs to be adjusted by mov-
ing one or more spacer washers. If the contact region
varies with blade rotation, one or both blades is likely
bent and in need of replacement.
Adjusting Disc Contact
!
CAUTION
Row unit disk blades may be sharp. Use caution when mak-
ing adjustments in this area.
Refer to Figure 103
1.
Raise the drill and lock it up by moving the Trans-
port/Field handle to TRANS.
2. Remove the bolt retaining the opener disc on one
side. Carefully remove the disc, noting how many
spacers are outside the disk and inside the disk. Do
not lose the hub components and spacer washers.
3. To reduce the spacing between the discs (the nor-
mal case), move one spacer washer from the inside
to the outside of the disc.
4. Re-assemble and check disc contact.
Disk Scraper Adjustments
To keep opener disks turning freely, dirt scrapers are
mounted between disks to clean as disks rotate. Stan-
dard 00 Series row units include a double-disk slotted
scraper.
Refer to Figure 104
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.
!
CAUTION
Row unit disk blades may be sharp. Use caution when making
adjustments in this area.
