Row Unit Adjustments
Refer to Figure 51
(which depicts a row unit fully populated with all optional
accessories supported for use with the 3S-3000HD 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
“Opener Height” on page 55.
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
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.
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 “Disk Scraper Adjustments”
on page 56.
6.
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
“Keeton Seed Firmer Adjustment” on page 57.
Seed-Lok™ firming wheel (not shown)
Improves seed-soil contact. See “Seed-Lok™ Seed
Firmer Lock-Up” on page 57.
7.
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 “Opener
Depth (Press Wheel Height)” on page 58.
Certain Machine Damage:
Do not back up with row units in the ground. To do so will
cause severe damage and row unit plugging.
