ABSTRACT:
A cross country ski grooming device comprising a track sled adapted to be towed by a vehicle in the direction of the track and having a pair of spaced apart tracking elements on the underside of the sled oriented in the direction of the track. Each tracking element comprises an elongated body which is trapezoidal in cross section and has a pointed wedge at its front end. The present invention lies in the improvement of the structure of the tracking elements by displacing the forward wedge tips away from the longitudinal center line of each tracking element in the direction toward the space between the tracking elements. This reduces the amount of snow passing between the tracking elements as the device is moved through the snow, eliminating objectionable compacting of the center ridge between the ski tracks.
