ABSTRACT:
A grubbing plow mounted on two lower arms and an upper attachment point of a 3-point tractor hitch includes a frame having (1) a horizontal pivotal bar journaled at opposite ends thereof on the lower hitch arms; (2) an upper crank arm; and (3) a lower member. The pivot bar is pivotally mounted for rotational movement about a horizontal axis. The upper crank arm and lower member are aligned and oppositely directed from the pivot bar.
A knife-edged, V-shaped blade is rigidly attached to the lower end of the lower member and lies in a plane perpendicular to the length of the lower member.
A hydraulic cylinder is connected between the upper attachment point and the upper end of the upper crank arm for forcibly swinging the blade in an arc around the axis of the pivot bar to engage and remove roots encountered within said arc.
