This invention relates to an endless traction band that is used to propel band-laying vehicles [i.e., vehicles which use endless traction bands rather than tires to contact the terrain over which they are driven, e.g., tractors, tanks, bulldozers, etc.] and, more particularly, to an improved traction band design for use with snowmobiles. The traction band comprises multiple sets of openings some of which are adapted to be engaged by a novel sprocket wheel.
