Abstract

A seeding system includes a frame mounted on ground wheels for moving across the ground together with a plurality of individually mounted seeding elements carried on parallelogram linkages from the frame. A seeding element includes a walking beam arrangement having a single front wheel and a pair of rear wheels straddling the seeding sweep positioned between the front and rear wheels. The rear wheels act as packer wheels for two rows of seeds. The walking beam system lifts a main support frame of the seeding element against the bias from a pressurized controlled hydraulic cylinder. The seeding sweep is mounted upon a trip shank. The seeds are supplied through a tube which splits at the sweep to deposit the seeds into the cavity within the sweep on either side of the center line of the sweep. A fertilizer banding knife projects downwardly and rearwardly from the lower end of the shank to a position rearwardly of the sweep. A trash cleaning system comprises a transverse shaft driving a plurality of tines which are rotatable about the axis of the shaft on either side of the seeding system to knock away trash collected in front of the shank.
