A snow vehicle and more particularly an improved track and driving arrangement therefor. The track has lugs on one side that are engaged with teeth of a drive sprocket for driving the track in a positive manner. The opposite side of the track and that which faces the ground has pairs of teeth disposed on opposite sides of the track drive lugs and each having different configurations which are mirror images of each other. One of the teeth of the pairs is configured to provide good traction in soft snow on its forward face and good traction on hard snow in its rearward face while the other tooth provides the opposite effects so that good traction will be provided in either direction of drive.
