Abstract
A folding planter includes a frame formed by first and second frame members supported for relative, longitudinal shifting movement, a primary fluid-actuated piston and cylinder assembly for shifting the first and second frame members between retracted and extended positions, and a pair of planter assemblies each supported on the second frame member for pivotal movement about a vertical pivot axis between an extended planting position and a retracted transport position. Each planter assembly includes a tool bar that extends transverse to the longitudinal axis of the frame in the planting position and parallel to the frame in the transport position, and a plurality of planting units supported on the tool bar. A pair of elongated trusses are connected between the first frame member and the planter assemblies. Each truss presents opposed ends supported for pivotal movement relative to the first frame member and one of the planter assemblies to permit the planter assembly to be moved between the planting and transport positions upon actuation of the primary piston and cylinder assembly. A mechanical linkage is connected to the primary piston and cylinder assembly and to the planter assemblies for driving pivotal movement of the planter assemblies upon actuation of the primary piston and cylinder assembly to assist the trusses in moving the planter assemblies completely into and out of the transport position.
