ABSTRACT:
An apparatus for grooming snowmobile trails is towed by a dirigible tracked vehicle and includes a generally horizontal main frame, a gooseneck hitch supporting the forward end of the frame in towing engagement with the tracked vehicle, a packing roller supporting the rear end of the frame which serves to pack the snow being groomed, a moldboard scraper mounted between the packing roller and the gooseneck hitch which serves to scrape and level the snow being groomed, and a cutting blade assembly mounted forwardly of the moldboard scraper cuts, breaks and moves snow to fill in grooves and level ridges. A floating pan secured to the rear end of the main frame smoothes the snow following packing by the roller. The snow breaking and cutting blade assembly includes a pair of opposed, spaced-apart cutting blades pivotally secured to the frame and inclined inwardly and rearwardly, and a central V-shaped cutting blade pivotally secured to the frame with the apex thereof directed forwardly. The inner free ends of the inclined blades and the apex of the V-shaped blade are coordinated for raising and lowering to cause the apex of the V-shaped blade to swing oppositely to the free ends of the inclined blades for purposes of controlling the flow of snow through the frame to the moldboard scraper and packing roller.
