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 extends rearwardly from beneath the press wheel at the lower end of an arcuate shank that is transversely guided on the press wheel structure or 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. The shank is guided by a series of rollers within a guide frame pivotally mounted on a supporting frame for motion about a transverse horizontal axis. Highly accurate planting depth control can be achieved, with provision for upward relative movement of the runner as required by encountered field conditions.
