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 41
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 1.75in (0-4.4cm).
If the contact region is significantly larger or smaller (or
there is no contact at all), it needs to be adjusted by
moving 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
Row unit disk blades may be sharp. Use caution when making
adjustments in this area.
Refer to Figure 42
1.
Raise the drill and install the transport locks.
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 normal
case), move one spacer washer from the inside to
the outside of the disc.
4. Re-assemble and check disc contact.
