Row Unit Adjustments
Refer to Figure 33
(which depicts a row unit fully populated with all optional
accessories supported for use on at least one 10HDP
model - some models may not support some
accessories)
From front to back, a Great Plains 10HD Series row unit
can include the following capabilities (some optional):
1.
Unit-Mounted Coulter (UMC): optional
UMCs cut residue and prepare the soil ahead of the
seed furrow. See page 49 for adjustments.
2.
Dual Down Pressure Springs: standard
Each row unit is mounted on the drill 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. See page 51
for adjustments.
3.
Row Unit Spring Cam: standard
This adjustment sets the down-force used by the row
unit. See “Row Unit Down-Force” on page 51.
4.
Row-Unit Lock-Up: holes standard, pins optional
If rows are shut off with seed tube plugs, row unit
wear can be reduced by locking them up. See “Row
Unit Shutoff” on page 54.
5.
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 57.
6.
Seed Tube with Shutoff (standard)
Seed flow to a row may be shut off by repositioning
the cap. See “Row Unit Shutoff” on page 54.
7.
Seed Meter (standard - choice of models)
A precision or finger pickup meter is standard, with a
choice of wheels or finger sets. See page 60 for
changing meters and wheels. See page 62 for finger
meter adjustments.
8.
Drive Coupler
Disengage unused rows during calibration or when
using alternate row spacings. See page 55.
9.
Scrapers: (spreader shown)
A lower separator/scraper is standard.
An upper rear carbide scraper is optional.
See page 132.
10. Seed delivery tube: standard
No adjustments are necessary. See page 54 for
seed tube shutoff above meter. Standard tubes
include a seed sensor for the optional seed monitor.
11. Seed firmer:
Reduces seed bounce and aids emergence by
pressing seed gently into the furrow.
A seed flap (not shown) is standard. See page 111
for replacement.
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 64.
Seed-Lok™ firming wheel (shown)
Improves seed-soil contact. See “Seed-Lok™ Seed
Firmer Lock-Up” on page 64.
12. 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 65.
Do not back up with row units in the ground. To do so
will cause severe damage and row unit plugging.
