From front to back, a Great Plains 30 Series row unit can
include the following capabilities (some optional):
0.
Seed Hopper: standard
(not shown - sits above meter)
1.
Parallel arms: standard
Each row unit is mounted on the planter with
spring-loaded parallel arms which allow each row
unit to independently move up and down while
staying horizontal. An adjustment is provided for the
springs. See “Row Unit Down Pressure” on
page 46.
2.
Row Cleaner: optional, single-arm
Row cleaners clear trash from rows, and have an
adjustment for clearing depth. See “Row Cleaner
Adjustments” on page 47.
3.
Coulter: optional, choice of disk blades
Coulters cut trash, and create a pre-groove for light
no-till planting. There is a selection of three blade
types. The depth relative to the opener is set by a
choice of hub mounting holes. See “Coulter
Adjustments” on page 48.
4.
Openers: standard, 2 per row unit
Opener double disk blades widen the coulter groove,
creating the seed bed. Setup controls depth, width
and sidewall angle. See “Row-Unit Opener
Adjustments” on page 49.

adjustments for depth and angle. They also accept
an optional scraper. See “Disk Angle and Side
Gauge Wheels” on page 49 and “Adjusting Gauge
