  • Patent number: 4415040
    Abstract: 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.
