Claim Text:
1. A vibratory plow system having a vibrator for transmitting oscillatory motion to a plow assembly for forming a narrow trench, said plow assembly comprising: an elongated plow blade extending lengthwise from an upper end to a generally opposing chisel end, and extending in width from a leading edge to a generally opposing trailing edge; a plurality of serrations disposed along said leading edge in a substantially contiguous series from an intermediate location to near said chisel end, for exerting a cutting force on subsoil during each successive oscillating stroke of said plow assembly as said plow blade moves along said narrow trench formed by said blade, each of said plurality of serrations having a tapered leading face defining a leading blade edge and a tapered upper side defining an upper edge, wherein said upper edge is oriented at an acute angle relative to said leading edge, and wherein said leading blade edge and said upper edge intersect to define a point, wherein each of said plurality of serrations has a reinforced tip extending across said point and along at least a portion of both said upper side and said leading face; and a lug positioned on said trailing edge near said chisel end.
