00HD Row Unit Adjustments
(which depicts a row unit fully populated with all
optional accessories supported for use with the
2S-2600HD/HDF drill)
From front to back, a Great Plains 00HD Series row unit
can include the following capabilities (some optional):
1. Opener height adjustment: standard
If a few rows need to run deeper, such as in tire
tracks, the arm’s pivot point may be lowered. See
2. Single Down Pressure Spring: standard
Each row unit is mounted on the drill as a pivoting
arm which allows the row unit to independently move
up and down. The adjustable spring provides the
force to get the row unit and attachments into the
Row Unit Down Pressure (Spring)
3. Disc Blades: standard, 2 per row unit
Double disc blades open a furrow, creating the seed
bed. Spacers adjust the blades for a clean furrow.
4. Seed delivery tube: standard
No adjustments are necessary.
5. Disk Scraper: optional
In sticky soils, a scraper helps keep the opener disks
operating freely. See “
6. Fertilizer delivery tube: optional
The tube may be reversed to drop fertilizer with the
main seed, or just ahead of the press wheels.
7. Small Seeds delivery tube: optional
The tube may be reversed to drop small seed near
the main seed tube, or just ahead of the press
wheels.
If fertilizer is also installed, the Small Seeds tube is
mounted outside the opener frame.
8. Seed firmer: seed flap (not shown) standard:
Keeton seed firmer (shown)
Improves seed-soil contact, and provides a stable
arm for a low-rate liquid fertilizer delivery tube. See
Seed-Lok™ firming wheel (not shown)
Improves seed-soil contact. See “
9. Press wheels: standard (choice of types)
These close the seed trench. The wheels also sup-
port the free end of the row unit, and provide the pri-
mary control over seeding depth. See “
Certain Machine Damage:
Do not back up with row units in the ground. To do so will
cause severe damage and row unit plugging.
