10 Series Row Unit Adjustments
Refer to Figure 47
(which depicts a row unit fully populated with all optional
accessories supported for use with the NTA3010 and
NTA3510 drill)
From front to back, a Great Plains 10 Series row unit can
include the following capabilities (some optional):
1.
Dual Down Pressure Springs: standard
Each row unit is mounted on the planter via parallel
arms which allow the row unit to independently move
up and down while remaining parallel to the ground.
The adjustable spring provides the force to get the
row unit and attachments into the soil.
2.
Row Unit Spring Cam: standard
This adjustment sets the down-force used by the row
unit. See “Row Unit Down Pressure” on page 44.
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 45.
4.
Seed delivery tube: standard
No adjustments are necessary.
5.
Disk Scraper: standard
In sticky soils, a scraper helps keep the opener disks
operating freely. See “Disk Scraper Adjustments”
on page 46. An optional carbide scraper is available.
6.
Seed firmer: seed flap (not shown) standard:
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 47.
Seed-Lok™ firming wheel (shown)
Improves seed-soil contact. See “Seed-Lok
7.
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 48.
Machine Damage Risk:
Do not back up with row units in the ground. To do so will
cause severe damage and row unit plugging.
