Abstract
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.
