A B S T R A C T A blow molded plastic snow scoop with a wear strip automatically attached to the lip during the blow molding procedure. The wear strip has two elongated slots, at opposite ends, each extending closely adjacent the respective ends. During the blow molding procedure, ribs of plastic material are extruded from the underside of the leading edge portion, through the slots, and are flattened to provide flanges en- gaging bottom surfaces of the wear strip alongside the slots. During the blow molding procedure, the wear strip is held by positioning pins inserted through the inner ends of the slots. When the pins are withdrawn following the molding procedure, they provide clearance cavities between the inner ends of the ribs and the slots enabling the ribs to shift inwardly along the slots with the cavities receiving the ends of the slots, to compensate for shrinkage of the plastic relative to the wear strip during cooling.
