Snowmobile drive track
Abstract:
An endless drive track for a snowmobile is provided with traction lugs that are inclined relative to normal to the track base. When the traction lugs are inclined away from the direction of travel for the track, the traction lugs can compress the snow before engaging the snow for traction, thereby providing lift for a snowmobile traveling in deep snow.
