ABSTRACT:
A seed drill includes a novel planting assembly combining press wheels for packing angular sides of a furrow and a runner immediately behind and longitudinally aligned with the press wheel. The runner includes an arcuate front edge that is juxtaposed immediately behind the coulter, thereby preventing accumulation of field trash between them. The runner extends rearwardly from beneath the press wheel and is transversely guided on the supporting vehicle frame of the drill to maintain it in longitudinal alignment within an open longitudinal slot cut through the soil and intersecting the base of the packed furrow. Seed is dropped into the open slot prior to being covered with soil. Moist soil can be packed along the sides of the furrow to maintain the furrow in an open condition during seed germination and plant emergence. Highly accurate planting depth control can be achieved, with provision for upward relative movement of the runner as required by encountered field conditions.
