Abstract

An apparatus for forming cross country skiing tracks in a snow covered surface. The apparatus is adapted to be towed behind a vehicle and includes a trailer frame connected to the vehicle in a manner permitting the frame to pivot at least in the horizontal plane. A blade and a ski track device are carried by the frame. The blade is adapted to contact and recondition the snow covered surface, and the ski track device is adapted to form skiing tracks in the thus reconditioned snow covered surface. The blade and the ski track device are each fixed against pivotal movement relative to the frame in the horizontal plane. Thus, the trailer frame, the blade and the ski track device pivot in the horizontal plane as a unit relative to the vehicle.
