Abstract: In one embodiment, an implement comprising a center section and a pair of wing sections, each of the sections comprising a pair of parallel frame members pivotably coupled to each other, wherein one of the frame members comprises a toolbar; and a plurality of hydraulic cylinders enabling rotational movement between the parallel frame members, wherein the hydraulic cylinders of the wing sections comprise double rod cylinders and the hydraulic cylinders of the center section comprises single rod cylinders.

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.

Abstract: In one embodiment, an implement load balancing method comprising sensing respective loads on one or more wheels supporting a central portion and one or more wheels supporting a wing portion, the central portion and the wing portion comprising segments of an implement; and causing, via actuation of a fluid-type cylinder, pivotal movement between the central portion and the wing portion based on the sensed loads, wherein the causing comprises causing fluid flow in one direction through the fluid-type cylinder based on a load on the one or more wheels supporting the central portion being greater than a load on the one or more wheels supporting the wing portion and causing fluid flow in an opposing direction through the fluid-type cylinder based on a load on the one or more wheels supporting the central portion being less than a load on the one or more wheels supporting the wing portion.
