A moldboard plow was modified such that the ap-proach-angle of the bottoms could be varied and held at a given angle by a hydraulic cylinder. Field tests of this plow verified that good plowing performance could be obtained at high travel speeds when the bottoms were operated at an approach-angle less than the design approach-angle.
