A gasoline engine powered snowboard having an endless track trained about a support frame containing driven and idler wheels. Engine operation is directed from an upright operator support column. A molded chassis is hinge coupled to pivot about alternative contoured track support pan assemblies. The pan support assemblies cooperate with flexible track surfaces (e.g. fringe or pleat members) and foot supports to enable steering with foot and body movements. A lower support pan exhibits convex edge surfaces that contact track pleats or fringe pieces and includes an elliptic longitudinal channel. Alternative upper support pans provide a reciprocating wheeled steering plate, longitudinal drive lug channels and contoured snow diversion surfaces and/or an agitator. Internal track surfaces include UHMW pieces at or aligned to the drive lugs. Ground contact lugs exhibit traction promoting and snow clearing contoured profiles, shapes and recesses.
