发明名称 Agricultural sweep having reinforcing ridge
摘要 An agricultural sweep has an upwardly extending stem adapted to be secured to a tine of an agricultural implement and a ground breaking member comprised of a pair of substantially planar wings diverging rearwardly from a tip. In order to prevent bending or breaking of the sweep, a reinforcing ridge is provided at the juncture of the wings and the stem, the ridge extending along a longitudinal axis of the sweep from the upper surface of the wings to a point on the stem between the base and the upper end of the stem.
