A plow of the type used to clear snow and like debris from roadways and similar surfaces has a plastic moldboard secured to a rigid frame adapted to be mounted to a vehicle. The frame has at least one vertically extending brace member spaced from the moldboard to define a vertically extending gap between frame and moldboard. At least a portion of the gap is at least partially filled with a resilient material so that the moldboard is able to resiliently flex into the gap during heavy snow removal while preventing the gap from being filled with foreign matter including ice otherwise preventing desired flexing of the moldboard.

[ Having thus defined the invention, it is claimed:] [10.] A vehicular plow of the type used to clear snow and like debris from roadways and similar surfaces comprising: a plastic moldboard; a rigid frame secured to said vehicle on one side thereof and to which said moldboard is assembled on the opposite side thereof, said frame having at least one vertically extending brace member spaced from said moldboard over a portion of its length to define a gap therebetween; and a resilient material at least partially filling at least a portion of said gap, said frame including top and bottom longitudinally mounting members vertically spaced from one another by a plurality of said brace members transversely spaced along the length of said mounting members, said moldboard connected to said mounting members when assembled into said frame, and said moldboard and the confronting portion of said brace member being inwardly curved to define said gap as an arcuate gap and said gap being non-uniform, said brace members being structural angle members, each brace member being orientated to have a V-shaped cross-sectional configuration with legs forming said V-shape such that said legs terminate in inwardly curved edges, said leg edges and back moldboard defining said arcuate gap and said resilient material interposed between each of said leg edges of each brace member and the back of said moldboard to substantially fill said gap, said resilient material being a block of material within said V-shape of each brace member and extending beyond said leg edges to substantially close said gap, wherein said block of material has an opening extending therethrough, said opening distorted when said resilient material is compressed.
