30 Series Row-Unit Adjustments
Refer to Figure 47, which depicts a 30 Series dual row unit
populated with most options supported on the YP1630F
(excepting scrapers and seed firmer, not visible)
1.
Down-Pressure Spring (Standard)
Row units are mounted on parallel arms. This
parallel-action mounting allows the row-unit to move
up and down while staying horizontal. Standard or
optional heavy duty springs add an adjustable force
to the row weight, set by the tee-handle. See “Row
Unit Down Pressure” on page 52.
2. Opener Discs (Standard)
Row-unit double disc openers create the seedbed
furrow. They have adjustments for angle and
spacing. See “Row-Unit Opener Disc
Adjustments” on page 53.
3. Unit-Mount Coulter (Option)
Coulters, with a choice of blades, cut trash and begin
opening the seed furrow. Working depth is set by row
depth and a mounting hole selection. See
“Unit-Mounted Coulter Adjustments” on page 53.
4. Seed Meter (Standard, Multiple Choices)
Pickup meters (6- or 12-finger) and brush meters
(multiple seed plates) are available, and mount to the
bottom of the forward (seed) hopper. See “Seed
Meter Adjustments” on page 58.
5. Seed Meter Coupler (Standard)
This knob disconnects the seed meter from the drive
system, for clean-out, calibration and treatment
setup. See “Meter Drive Adjustments” on page 90.
6. 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. See “Side Gauge Wheel
Adjustments” on page 54.
7. Seed Firmers (Seed Flap Standard, not shown)
An optional seed firmer (Keeton
®
shown) minimizes
seed bounce and improves soil contact. It may also
deliver fertilizer. See “Seed Firmer Adjustments”
on page 61.
8. Scrapers (Optional, not shown)
Inside scrapers require no adjustment. For gauge
wheel scrapers, see “Adjusting Gauge Wheel
Scrapers” on page 55.
9. Press Wheel Force, Angle, Stagger (Standard)
The press wheels close the furrow, gently pressing
the soil over the seed to ensure good seed to soil
contact for even emergence. See “Press Wheel
Adjustments” on page 62.
10. Press Wheel Type (Choice)
A variety of single and dual press wheel assemblies
are available, some region-specific. Consult your
Great Plains dealer.
11. Treatment Meter (Option)
This meter, under the optional rear hopper, controls
application insecticide, pesticide and similar granular
materials. See Seed Rate Manual.
12. Treatment Drive Coupler (Standard w/Treatment)
This coupler disconnects the treatment meter from
the row drive system, for clean-out, calibration, and
when not applying treatments. Adjustment is same
as seed driver coupler (page 90).
