Forged toothed wheel for a row crop planter

An agricultural closing wheel comprising:

• a hub having a respective width and defining a central axis Z about which the wheel rotates in use, the hub having an outer edge defined by an internal periphery with a periphery diameter D2 and an inner edge defined by an internal circular hole with an internal diameter D1;
• a plurality of teeth projecting radially outwardly from the hub to move soil into a furrow as the wheel rotates clockwise about its central axis, each tooth of the plurality of teeth having
• a tooth root adjacent to the internal periphery of the hub,
• 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 W, the width of the hub being substantially thinner than the maximum tooth width W,
• a trailing surface opposite the leading soil-contacting surface and extending from the tooth root in a curved counterclockwise manner, and
• a tooth end angled counterclockwise away from a radius passing from the central axis Z through a central point of the tooth root, the tooth end converging to a point and terminating on a maximum outside diameter D5 of the wheel, the tooth end connecting the leading soil-contacting surface and the trailing surface, the tooth end trailing behind the leading soil-contacting surface relative to the clockwise wheel rotation;
• and
• an adjoining root valley between each pair of adjacent teeth of the plurality of teeth, the root valley being along a tooth depth diameter D4 and having a thickness T that is substantially thinner than the maximum tooth width W.
