SUSPENSION AND DRIVE SYSTEM FOR A MACHINE

A suspension and drive system includes front and rear torsion axle assemblies. The front torsion axle assembly includes a front axle, a front shaft, and a front arm connecting the front axle to the front shaft. The rear torsion axle assembly includes a rear axle, a rear shaft, and a rear arm connecting the rear axle to the rear shaft. A center of the front torsion axle assembly and the rear torsion axle assembly together define a quadrilateral. The front axle defines a first vertex of the quadrilateral, the front shaft defines a second vertex of the quadrilateral, the rear shaft defines a third vertex of the quadrilateral, and the rear axle defines a fourth vertex of the quadrilateral. An interior angle of the quadrilateral at the fourth vertex is less than an interior angle of the quadrilateral at the second vertex.
