25 Series Row Unit Adjustments
Refer to Figure 97
(which depicts a row unit fully populated with all
optional accessories supported for use with the
1525P drill).
From front to back, a Great Plains 25 Series row unit can
include the following capabilities (some optional):
1. Dual Down Pressure Springs: standard
Each row unit is mounted on the drill with parallel
arms which allow each row unit to independently
move up and down while staying horizontal.
Adjustable springs provide the force to get the row
unit and attachments into the soil. See “
25P Series
Down-Pressure ” on page 73.
2. Row cleaners: optional
Row cleaners clear trash from the row. Twin-row
drills support single-arm cleaners. Single-row drills
support single- or double-arm cleaners. See
“
Unit-Mount Cleaner Adjustments ” on page 77.
3. Disk Coulter: optional, choice of blades
Coulters cut any remaining trash, and create a
groove for light no-till planting. The down force
needed to cut and widen the coulter groove is
supplied by the row unit. The depth relative to the
opener is set by a choice of hub mounting holes. See
“
Coulter Adjustments ” on page 78.
4. Disc Blades: standard, 2 per row unit
Double disc blades widen the coulter groove,
creating the seed bed. Setup controls depth and
width. See “
Row-Unit Opener Disk Adjustments ”
on page 80.
5. Depth Side Gauge Wheels: standard
The depth gauge wheels have adjustments for
spacing and angle. See “
Side Gauge Wheel
Adjustment ” on page 82.
6. Seed meter: required, choice of models/features
Meters deliver singulated or volumetric seed. See
“
Changing Seed Meter Wheel ” on page 63.
7. Seed delivery tube: standard (not shown)
No adjustments are necessary.
8. Seed firmer (optional):
Keeton seed firmer (shown mounted)
Improves seed-soil contact, and provides a stable
arm for a low-rate liquid fertilizer delivery tube. See
See “
Keeton
®
Seed Firmer Adjustment ” on
page 84.
Seed-Lok
®
firming wheel (shown in inset)
Improves seed-soil contact. See “ Seed-Lok

Seed
Firmer Lock-Up ” on page 84.
9. Gauge Wheel Scraper: optional
The depth gauge wheels also accept an optional
scraper. See “ Spreaders and Scrapers ” on
page 101.
10. Press wheels: standard (choice of types)
These close the seed trench. See “ Press Wheel
Adjustment ” on page 85.
Machine Damage Hazard:
Do not back up with row units in the ground. To do so will
cause severe damage and row unit plugging.
