ABSTRACT:
An apparatus for making ski tracks and/or levelling ski slopes is mounted in front of a driving vehicle so as to be freely vertically movable relative to the vehicle to adjust its position to varying snow heights encountered in treating the snow cover. Front and rear supports such as sleds or rollers are pivotally mounted on the frame and support the apparatus on the snow cover. A rotating cutting tool for treating the snow is mounted on an arm which is pivotally joined to the frame, to allow the cutting tool to swing upward and downward relative to the frame in response to varying snow heights. The cutting tool support arm may be resiliently mounted to bias the cutting tool in a downward direction to provide a flatter snow surface. At least one of the front and rear supports may be swingably mounted similarly to the cutting tool. The apparatus produces a flatter snow cover in areas of varying length of waves in the snow surface.
