A track laying work vehicle has an undercarriage assembly including a rigid support beam and first and second roller frame assemblies, one on either side of the vehicle. Each roller frame assembly has first and second end portions and supports a rotatable idler wheel assembly at the first end portion and a powered drive wheel at the second end portion. Each drive wheel is frictionally engaged with a drive axle of the vehicle and can be engaged with the drive axle at a plurality of lateral positions on the axle. The first end portion of each roller frame assembly is releasably connected to one end of the support beam and is laterally moveable on the support beam. An endless track, such as an elastomeric belt, encircles a respective drive wheel, roller frame assembly, and idler wheel assembly on each side of the vehicle. By moving the track roller frame assembly and drive wheel laterally along the drive axle and support beam respectively, various gage settings of the endless track are provided.
