ABSTRACT:
A snow grooming apparatus for towing behind a pulling vehicle to handle and condition snow, as an example, on ski slopes or cross country trails. The apparatus includes a scraper and snow collector assembly including a scraper blade and hopper followed by a roller assembly. As the apparatus moves forwardly the blade scrapes or cuts the surface of the snow and confines the cut snow in the hopper. The hopper includes at opposite sides thereof a pair of pivoted floated side panels, the bottom edges of which follow the grade or terrain and help to prevent the cut snow in the hopper from escaping out the sides of the hopper. As the apparatus continues to move forwardly, the cut or powder snow is redeposited almost immediately in low areas of the terrain. Finally the roller assembly moves across the redeposited snow and compacts and conditions the surface for safe recreational purposes.
