A track assembly having a drive sprocket capable of concentrically supporting several detachable drive rings containing drive teeth shaped to rotate without interfering with track support idler wheels, to provide a reduced center of gravity and substantially provide the same vehicle operating characteristic with tracks as with wheels. A track retainer guide member mounts along a peripheral edge of the track and overlies the track to resist track dislodgement. Independent and/or resiliently biased, rocker arms support track idler wheels to induce track flexion and conformance to encountered obstructions. |
