Spring-Tine Residue Wheel for Planters

摘要

The residue wheel has a plurality of multiply bent spring-steel tines that project outwardly from their central hub at such angles that straight foot portions of the tines engage and lie flatly against the ground as the tines sweep residue rearwardly and outwardly during rotation of the wheel about an axis oblique to the path of travel of the planting machine. The tines are equally spaced about the wheel but are arranged in pairs, comprising individual legs of a generally U-shaped, integral unit having a bight at the inner ends of the the legs that joins the legs together and serves as a means by which the unit can be clamped between opposed, flat plates of the hub. Short downturned driving prongs at the outer ends of the legs provide traction for the wheel during use.
