Abstract
An agricultural machine includes a frame having a tongue hitch for attachment to a towing vehicle, the tongue hitch being oriented along a longitudinal axis inline with the direction of travel. The agricultural machine has running gear configured to support the frame. The running gear includes an axle mounted to the frame and a swing arm pivotably mounted to the axle defining a main pivot axis. A front spindle is mounted at the front end of the swing arm with a front tire mounted to the front spindle and a rear spindle is mounted at the rear end of the swing arm with a rear tire mounted to the rear spindle. The tires are positioned on a same side of the swing arm. The front tire has a smaller diameter than a diameter of the rear tire.
