From front to back, a Great Plains 07 Series row unit can

1. Disc Blades: standard, 2 per row unit
Double disc blades open a furrow, creating the seed

The adjustable springs provides the force to get the
row unit and attachments into the soil prepared by
the coulter. See “ Opener Down Pressure ” on
page 36.
3. Main Box Seed Delivery tube: standard
No adjustments are necessary.
4. Seed firmer: seed flap (shown) standard
