ABSTRACT:
A vibratory plow including a cutter assembly which slices the ground covering and breaks the sod ahead of the cable-laying plow blade. The plow assembly includes a blade holder that is pivotally mounted to a vibrator frame. A mounting member attaches the cutting blade of the cutter assembly to the blade holder. The cutting blade is polygonal in shape and includes a plurality of mounting holes located in polygonal patterns. The mounting member includes a complementary set of mounting holes also arranged in a polygonal pattern. The present construction permits the cutting blade to be moved to a plurality of cutting positions rather than replacing the cutter after a cutting edge is worn.
