ABSTRACT:
A vehicle such as a combine harvester or the like includes a main frame and a first and second undercarriages for supporting the main frame and individually having front and rear wheel assemblies and a track encircling the wheel assemblies. A suspension structure therefore includes a laterally spaced apart pair of pivot joints adjacent the front wheel assemblies for pivotally connecting the undercarriages to the main frame, and a coupling assembly adjacent the rear wheel assemblies for centrally supporting the main frame on the undercarriages. A hydraulic motor powerably rotates each of the rear wheel assemblies and an inside support device is provided therefor that includes a stabilizing beam. The coupling assembly includes an equalizer bar having outer ends, and the stabilizing beam extends rearwardly beyond the driven rear wheel assemblies for connection to the outer ends. Also, an outside support device releasably clamps the rear wheel assemblies to the undercarriages.
