Abstract

A combine harvester has a suspension axle assembly supporting the rear end of the chassis of the harvester. Side frames of the chassis direct loading down to a transverse axle through a pair of suspension devices interposed between the side frames and the axle. The suspension devices are resilient and expandable to cushion the chassis and to provide changes in the fore-and-aft attitude of the combine. The suspension devices may be independently operated to tilt the axle relative to the chassis, and provision is made for shifting the axle longitudinally, side-to-side of the chassis to facilitate turning of the steerable rear ground wheels.
