ABSTRACT OF DISCLOSURE A power driven ski vehicle of the ski bob kind is driven by a power ski having a pair of running surfaces on the undersides of the power ski for sliding engagement with the snow and for supporting a substantial portion of the weight of the vehicle and rider. Each of the running surfaces is disposed intermediate an outboard turning flange, located along the outer ski edge, and a central tunnel through which a propulsion track travels. Preferably, the running surfaces are inclined in the transverse direction and their inner edges define a pair of inner reaction or turning edges parallel to the outer turning flanges. The entry and exit ends of the tunnels are configured to reduce wear of the propulsion track as it enters and exits the underside of the ski and is changing its direction of travel. -1-
