unit populated with most options supported on the
YP1630F (excepting scrapers and seed firmer, not

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 T-handle. See “
2.
Opener Discs
(Standard)
Row-unit double disc openers create the seedbed
furrow. They have adjustments for angle and
spacing. See “
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

height of the side gauge wheels relative to the
opener discs. See “

seed bounce and improves soil contact. It may also
deliver fertilizer. See “

wheel scrapers, see “

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 “

A variety of single and dual press wheel assemblies
are available, some region-specific. Consult your
Great Plains dealer.

application insecticide, pesticide and similar granular
materials. See
