摘要： A fully mounted variable width plow of the roll-over type or not in which the tractor hitch links are pivoted about generally vertical axes permitting the hitch limited movement in a horizontal plane, which will allow the adjusted plow to maintain correct alignment under the action of the soil. The plow system includes a plow beam, to the forward end of which a forecarriage is pivotally attached about a vertical axis, and a plurality of interconnected plow bottom assemblies. Actuation of a hydraulic cylinder will result in equal pivotal movement of each plow bottom assembly relative to the plow beam as well as pivotal movement between the forecarriage and the plow beam.

摘要： An adjustable width plow having its diagonal frame pivoted to a forecarriage unit at a point such that pivotal adjustment of the frame relative to the forecarriage results in both a variation in the cutting width and a transverse displacement in the proper amount of the first plow bottom in the appropriate direction.
