ABSTRACT:
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 compactor and power means for rotating the wings upwardly. The outer ends of the wings are secured to the inner ends by shear bolts or pins so that when an outer end contacts a rigid object it falls away and is not damaged. Means is provided for adjusting the angle of attack of the bottom wall of the snow compacting element to the surface of the snow to vary the pressure exerted upon it. Power means is also provided for moving the elements of the snow compacting apparatus above the rear portion of the towing vehicle for transporting the snow compactor to and from ski trails and to and from the locality where the compacting apparatus is stored. Snow roller means is provided to partially compact the snow between the tracks of the towing vehicle as the compactor is moved forwardly so that the snow beneath the roller is partially compacted to about the same density as the snow which is partially compacted by the tracks of the vehicle.
