Disc Scraper Adjustment
To keep opener discs turning freely, dirt scrapers are
mounted between discs to clean as the discs rotate. As
field conditions vary, scrapers may need to be adjusted.
In damp conditions, scrapers may need to be lowered. If
openers are not turning freely, scrapers may need to be
raised.
Re-adjust scrapers when replacing discs or adjusting
disc spacing.
Refer to Figure 15
To adjust scrapers, loosen
3 ⁄
8
inch bolt shown in and
move scraper as needed.
Seed Firmer Adjustments
Standard 05/06 Series row units include a seed flap.
An optional Seed-Lok
®
or Keeton
®
seed firmer may be
ordered separately.
The seed flap requires no adjustment, but may need to
be replaced if worn, and may need to be shortened if an
optional seed firmer is added after initial delivery. See
also “Seed Flap Replacement” on page 30.
Sharp Object Hazard:
Use caution when making adjustments in this area. Row unit
disc blades may be sharp. To adjust the Keeton
®
Seed Firmer,
lower the drill until the discs of the row units are resting on the
ground.
Seed-Lok
®
Lock-Up (Option)
Optional Seed-Lok
®
firming wheels provide additional
seed-to-soil contact. The wheels are spring loaded and
do not require adjusting. In some wet and sticky
conditions the wheels may accumulate soil. To avoid
problems associated with this, you can lock-up the
firmers.
Refer to Figure 16 (shown with an opener disc removed for
clarity - this task can be performed with discs mounted)
To lock up Seed-Lok
®
wheels:
1. Pull catch wire aside.
2. Pull firming-wheel arm up and release wire to
catch arm.
