Abstract: An improved truck for track type tractors having resiliently mounted track roller assemblies. The truck includes an elongated frame journalling sprockets at opposite ends about which an endless track is trained. A plurality of track roller assemblies engage the lower run of the track and are resiliently secured to the frame to cushion vertical movement of the track roller assemblies. A linkage system or, in the alternative, a cable system, interconnects the track roller assemblies and the frame to restrain the track roller assemblies against longitudinal shifting relative to the frame. Depending side members secured to the frame are in sliding contact with opposite ends of each track roller assembly to restrain the same against side-to-side shifting movement.
