4.11.4 Adjusting Disc
Contact
Use caution when making adjustments in
this area. Row unit disc blades may be
sharp.
Unfold implement. Configure implement for
maintenance lift lock (page 29).
Remove the bolt retaining the opener disc
on one side. Carefully remove the blade,
noting how many spacers are outside the
disc and how many are inside the disc. Do
not lose the hub components and spacers.
To reduce the spacing between the discs
(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 discs are mounted.
Re-assemble and check disc contact.
4.11.5 Opener Disc
Scraper Adjustments
Slotted disc scrapers are standard. Spring-
loaded carbide disc scrapers are optional.
To keep opener discs turning freely, dirt
scrapers are mounted between discs to
clean as discs rotate.
Use caution when making adjustments in
this area. Row unit disc blades may be
sharp.
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.
