ABSTRACT:
An agricultural implement having a transverse main frame and transversely extending tool-carrying outer sections rearwardly foldable for transport. The main frame supports a pair of slide members which shift laterally thereon and to which the outer sections are pivotally connected. A hydraulically powered cylinder shifts the slide members transversely to separate the outer sections and provide clearance for tools carried thereon and smaller hydraulic cylinders swing each outer section about the pivotal connection and between their transverse and fore-and-aft positions.
