NARROW-BASE TERRACING PLOW

摘要

A narrow-base terracing plow comprising a tractorborne transverse frame supporting a pair of transversely spaced rearwardly and outwardly extending gangs of inwardly directed disc harrows, each gang being pivotally mounted on a mounting bracket for vertical swinging movement relative thereto and the mounting bracket being mounted on said frame for swinging movement about a vertical axis, each gang having a rigid link pivotally connected thereto and to the frame and having a hydraulic cylinder extending between its mounting bracket and the medial portions of the gang by means of which the outer end portion of the gang can be forced downwardly into the soil to a greater extent than its innermore portions, thereby causing the soil through which it passes to be moved laterally toward the centerline until a terrace is formed between the gangs and peaks thereat. Novel methods of utilizing the plow are also disclosed in which by forcing the outer end portions downwardly during the repeated passes, it will move the earth centrally and thereby form such a terrace.
