10HD Series Row Adjustments
Refer to Figure 96
(which depicts a row unit fully populated with all
optional accessories supported for use on a
1510HDP)
From front to back, a Great Plains 10HD Series row unit
can include the following capabilities (some optional):
1. UMC Row Cleaner: optional
Row cleaners clear debris ahead of the furrow. See
“
Unit-Mount Cleaner Adjustments ” on page 77.
2. Unit-Mounted Coulter (UMC): optional
UMCs cut residue and prepare the soil ahead of the
seed furrow. See “
Coulter Adjustments ” on
page 78.
3. 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 springs provide the force to get the
row unit and attachments into the soil. See “
10HDP
Series Down-Pressure ” on page 71 for
adjustments.
4. Row Unit Spring Cam: standard
Adjustment sets the down-force used by the row unit.
See “
2-Spring 10HD Cam Down-Force Settings ”
on page 71.
5. 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 Lock-Up ” on page 76.
6. 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 “
Row-Unit Opener Disk Adjustments ” on
page 80.
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 63 for
changing meters and wheels. See page 67 for finger
meter adjustments.
8. Drive Coupler
Disengage unused rows during calibration or when
using alternate row spacings. See page 75.
9. Scrapers: (spreader shown)
A lower separator/scraper is standard.
An upper rear carbide scraper is optional.
See page 101.
10. Seed delivery tube: standard
No adjustments are necessary. See page 75 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 102
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 84.
Seed-Lok™ firming wheel (shown)
Improves seed-soil contact. See “
Seed-Lok
®
Seed
Firmer Lock-Up ” on page 84.
12. 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 “
10HDP
Opener Depth ” on page 70.
Machine Damage Hazard:
Do not back up with row units in the ground. To do so will
cause severe damage and row unit plugging.
