This invention is directed to an apparatus for compacting snow for skiing and snowmobiling. It includes an elongated snow compacting member with means which permit its ends to move upwardly and downwardly so that when one end contacts an elevated snow surface that end automatically moves upwardly to substantially equalize the p.s.i. exerted by the snow compacting member against the snow which is being compacted. It also includes snow compacting wings which extend outwardly from and are pivotally secured to the central snow compacting section of the snow ...


An apparatus for compacting snow for sking comprising, an elongate central section having a substantially flat bottom wall, first elongate frame means substantially parallel to said central section when viewed from the top, means for securing said first elongate frame means to said central section, second elongate frame means substantially parallel to said first elongate frame means and located forwardly thereof, first pivot means located substantially at the centers of said first and second frame means for providing pivotal movement of said first frame ...
