摘要： An apparatus for producing ski tracks for a ski trail, comprising a sliding/planing body with a flat sliding surface which curves upwardly at the forward section of said body, and spaced-apart track-forming members depending downwardly from said sliding surface. The track-forming members each comprising a bottom surface and two parallel side surfaces whose forward portions converge to form a plow portion while the bottom surface extends forward in full width beneath said plow portion and at least to the tip of it. A drag frame pivotally attached to the surface of the sliding/planing body rearward of its forward section. The axis of pivot for the frame running transversely of the direction of advancement for the sliding/planing body. The trackforming members producing a track with strong, compacted walls, without weighing down the apparatus.
