ABSTRACT:
At least one trailing scraper member freely swingable within a vertical plane is provided, which has a scraper blade and a scraper base disposed at an acute angle relative to the blade. The angle of adjustment of the scraper member relative to the snow surface over which the device travels is adjustable, so that the scraper member either removes snow from the snow surface or slides over same. Associated with the scraper member is a scooping device limited by side walls and by a shield which can be lifted or lowered, in order to collect the snow provided by the scraping member and to transport same to another location and discharge same on lifting of the shield. In order to facilitate the discharge of snow accumulated within the scoop and to provide the shield with a further utility, the shield is curved in arcuate fashion about a generally horizontal axis perpendicular to the direction of travel of the device and is selectively attached to an arm either with its concave face or with its convex face turned in the direction of travel of the device. In the first case, the shield serves as a closing gate of the scoop device. In the second case the shield is utilized as a grading shield or blade disposed behind the trailing end of the scraping device. The advance in the art is in a more versatile application and in an improved performance when grooming wet snow surface.
