Abstract
An agricultural ground working apparatus includes a mounting bracket adapted for attachment to an implement frame. A shank is pivotally attached to the mounting bracket about a shank pivot axis and extends downward from the mounting bracket to a lower end thereof adapted for engaging the ground. Right and left disc arms are pivotally attached at upper portions thereof to the mounting bracket such that the disc arms pivot about arm pivot axes independent of the shank. The disc arms extend rearward and downward from the mounting bracket on each side of the shank, and right and left discs are rotatably attached to lower portions of the corresponding right and left disc arms.
