ABSTRACT:
A ground working implement consisting of a hitch, a center section pivotally secured to the hitch for rotation about a transverse axis and a two part wing section pivotally secured to each side of the center section for rotation about a longitudinal axis, with the two parts joined on a diagonal axis, a transverse member across the central region of the hitch, a member pivotally secured between the wing section and the end of a bar such that the rotational movement of the wing parts about a diagonal axis, the rotation of the complete wing about a longitudinal axis, and the rotation of the hitch about a transverse axis, is permitted during ground cultivation, and when the wing section is raised vertically for transportation purposes, the hitch becomes rigid with the center section and movement about all axis is locked.
