ABSTRACT:
A blade assembly for a tractor or other like vehicle of the type adapted for movement over snow covered terrain, having a horizontally extending first blade with second blades mounted at the opposite ends thereof for pivotal movement about vertical axes. Top plates are fixed relative to and extend forwardly from the first and second blades. The second blades are pivotally adjustable between open positions extending angularly outwardly from the first blade, and closed positions extending angularly inwardly from the first blade to cooperate therewith in defining an enclosure. The enclosure has a bottom opening defined by the lower edges of the blades, and a top opening which is smaller than the bottom opening and which is defined at least in part by the top plates.
