ABSTRACT:
A grass seed drill particularly adapted for the planting of native grass type seeds which are characterized by a low density, irregular length and shape, and having a propensity to stick together. The drill has a pair of seed boxes, at least one of which is adapted to handle the aforementioned type of seeds. The seed box has a plurality of bins with downwardly converging side walls terminating at a horizontal bottom wall provided with an elongate seed discharge opening. An agitator in each bin has a plurality of rotatable blades shaped and sized to rotate about a path substantially conforming to the shape of the interior of the bin and agitate the seeds located therein. A picker wheel associated with the discharge opening discharges seeds into a transition or seed funnel located substantially directly above a drill shoe which discharges the seed into the soil. A press wheel follows the shoe to compact the soil around the seed.
