ABSTRACT:
A folding implement has a pair of oppositely, laterally projecting tool beams which pivot about vertical axes between wide-spread, working positions and fold-back, transport positions in which the beams are substantially parallel to the path of travel of the implement. A secondary tool assembly situated behind the primary tool beams can swing about a transverse horizontal axis between a fully raised position for transport and a fully lowered position for working the ground. Push rod structure interconnects the secondary assembly with the primary beams so that as the primary beams are swung back to their transport positions, the secondary assembly is raised to its upper position, and conversely, as the primary beams are swung forwardly into their working positions, the secondary assembly is lowered into its ground-engaging position.
