ABSTRACT OF THE DISCLOSURE A track assembly for use on track-supported vehicles, such as excavators and the like, including a driven sprocket, a rigid undercarriage which extends forwardly of the sprocket and which supports the body of the vehicle, the undercarriage being supported by a series of linearly aligned track rollers, and an idler assembly, including a rigid linking member and idler wheel. The linking member is pivotally mounted on the front of the undercarriage and extends for- wardly therefrom, and the idler wheel is rotatably mounted on the front of the linking member. A motor means attached to the undercarriage and to the linking member selectively moves the idler assembly from a first position wherein the bottom of the idler wheel is lower than the bottom of the track rollers, and a second position wherein the bottom of the idler wheel is higher than the bottom of the track rollers. An endless track forms a circuit about the sprocket, track rollers and idler wheel. - 1 -
