00 Row Unit Adjustments
Refer to Figure 49 (which depicts a row unit fully populated
with all optional accessories [except scraper and Keeton
®
]
supported for use with the Model 2S-2600/F Three Section
3000 Folding Drills)
From front to back, a 00 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
“Opener Height” on page 55.
2. Single Down Pressure Spring: standard
Each row unit is mounted on the Three Section 3000
Folding 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 soil. See “Row Unit
Down Pressure (Spring)” on page 55.
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.
See “Disk Blade Adjustments” on page 56.
4. Main seed delivery tube: standard
No adjustments are necessary.
5. Disc Scraper: standard (not shown)
In sticky soils, a scraper helps keep the opener discs
operating freely. A slotted scraper is standard.
A spring-loaded carbide scraper is optional. See
“Opener Disk Scraper” on page 95.
6. Seed firmer:
seed flap (not shown) standard:
Seed-Lok
®
firming wheel (shown)
Improves seed-soil contact. See “Seed-Lok™ Seed
Firmer Lock-Up” on page 57.
Keeton
®
seed firmer (not shown)
Improves seed-soil contact, and provides a stable
arm for a low-rate liquid fertilizer delivery tube. See
“Keeton Seed Firmer Adjustment” on page 57.
7. Fertilizer delivery tube: optional
The tube may be reversed to drop fertilizer with the
main seed, or just ahead of the press wheels.
8. 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.
9. Press wheels: standard (choice of types)
These close the seed trench. The wheels also
support the free end of the row unit, and provide the
primary control over seeding depth. See “Opener
Depth (Press Wheel Height)” on page 58.
Equipment Damage Risk:
Do not back up with row units in the ground. To do so will
cause severe damage and row unit plugging.
