10P Series Row Unit Adjustments
Refer to Figure 124
(which depicts a row unit fully populated with most optional
accessories supported for use with the 3N-4010P 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 “10P Series Row Unit Down Pressure”
on page 96.
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 “10 Series Disk Blade Adjustments” on
page 97.
4. Shut-Off Cap (Standard)
Disable rows for alternate row spacing. See “Row
Unit Shut-Off” on page 79.
5. Singulating Seed Meter (Standard)
6. Seed delivery tube (Standard)
No adjustments are necessary.
7. Disk Scraper (Optional)
In sticky soils, a scraper helps keep the opener disks
operating freely. An optional carbide scraper is
available. See page 167.
8. Seed Firmer (Seed Flap Standard, not shown)
Keeton
®
seed firmer (not shown)
Improves seed-soil contact, and provides a stable
arm for a low-rate liquid fertilizer delivery tube. See
“10 Series Keeton

Adjustment” on page 98.
Seed-Lok
®
™ firming wheel (shown)
Improves seed-soil contact. See “10 Series

9. Side Gauge Wheel Depth (Standard)
The T-handle sets planting depth by controlling the
height of the side gauge wheels relative to the
opener discs.
10. Press Wheel Type (Choice)
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 “10 Series
Opener Depth” on page 99.
Certain Machine Damage:
Do not back up with row units in the ground. To do so will
cause severe damage and row unit plugging.
