A wheel axle for a combine harvester is described. The wheel axle has left and right wheel suspensions which form an adjustable 4-bar linkage structure, to which can be mounted ground-contacting elements, e.g. wheels or tracks. The adjustable wheel suspension allows for the wheel axis of the axle to be adjusted in both vertical height and vertical alignment, thereby allowing the ground-contacting surface area of the wheels or tracks to be maximised for uneven terrain. The adjustable link of the wheel suspension may comprise an adjustable actuator such as a hydraulic cylinder. The combine harvester may comprise dual tyres or continuous tracks mounted on at least one wheel axle.
