Abstract: A guide wheel for a track apparatus is provided. The guide wheel includes a central hub rotatably mounted to a frame of a track apparatus. A first guide wall extends radially from the central hub and terminates at an outer edge. A second guide wall also extends radially from the central hub and terminates at an outer edge. The first and second guide walls define a circumferentially extending channel in the guide wheel. The channel in the guide wheel sequentially receives a plurality of lugs extending from the inner surface of a flexible track of the track apparatus so as to prevent lateral movement of the track.
