Forged toothed wheel for a row crop planter
Abstract:
A forged agricultural wheel with a radial grain pattern includes a plurality of teeth projecting radially outwardly from a hub, with each tooth having a tooth root adjacent to the internal periphery of the hub. Each tooth further has a leading soil-contacting surface extending from the tooth root in a curved counterclockwise manner and having a variable width with a maximum tooth width. A trailing surface opposite the leading soil-contacting surface extends from the tooth root in a curved counterclockwise manner. A tooth end is angled counterclockwise away from a radius passing from a central axis through a central point of the tooth root. The tooth end connects the two surfaces and converges to a point on a maximum outside diameter of the wheel. An adjoining root valley connects each pair of adjacent teeth and has a thickness that is substantially thinner than the maximum tooth width.
