Abstract
A hydraulic system for a farm implement includes a wing elevation circuit, a wing folding circuit, and a hydraulic valve block assembly. The wing elevation circuit lowers or raises the wings of the farm implement relative to a frame of the farm implement between a first position, in which the wings extend approximately collinear with a lateral axis of the frame, and a second position, in which the wings extend beneath the lateral axis of the frame. The wing folding circuit folds or unfolds the wings between the first position and a transport position, in which the wings are rotated beyond a vertical axis transverse to the lateral axis. The hydraulic valve block assembly is in communication with the wing elevation circuit and the wing folding circuit and controls hydraulic fluid flow in the wing elevation circuit and in the wing folding circuit.
