ABSTRACT:
A two-way gang plow is provided with a main support frame arranged for connection to a conventional three point hitch of a tractor. The forwardmost pair of plow bottoms are secured in fixed position on a portion of the roll-over plow frame that is fixed against angular adjustment relative to the longitudinal direction of movement of the plow by the tractor. The pairs of plow bottoms trailing the forwardmost pair are mounted on a plow frame that is pivoted to the fixed roll-over frame section for angular adjustment relative to the longitudinal axis of the main frame and hence the direction of the movement of the tractor. The pairs of plow bottoms rearwardly of the forward most pair also are mounted on the angularly adjustable frame for pivotal movement relative to said frame, for adjusting the land sides of the plow bottoms relative to said angularly adjustable frame. All of said trailing pairs of plow bottoms are interconnected pivotally by a link connected pivotally to the fixed portion of the roll-over frame. Accordingly, angular adjustment of the plow bottom support frame relative to the longitudinal direction of movement of the tractor maintains all of the land sides of the plow bottoms parallel to the direction of movement of the tractor, whereby to effect adjustment of the lateral spacing between adjacent land sides and accommodate use of the plow in a variety of types and conditions of soil.
