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.

Folding seed planter

The working depth of obliquely angled disc gangs on the implement can be readily adjusted from the tractor seat with a single hydraulic cylinder through the use of mechanical linkage that couples the hydraulic cylinder with all of the disc gangs for simultaneous movement. Special pivots that join the gangs to the main frame permit the gangs to be manually angled adjusted without affecting depth, and vice-versa, while quick-release locks securely hold the gangs in their selected angular positions yet permit rapid adjustment.

Tillage implement with on-the-go depth control of angle adjustable disc

A tillage implement which has both deep tillage subsoil shanks at the rear of the machine and relatively shallow running, residue cutting and topsoil mixing discs at the front of the machine provides for expeditious depth adjustment of the discs through spacer blocks that may be inserted between the underside of the frame of the implement and the tops of the gang beams. The blocks are designed to be clamped in position beside pivot bolts and angle retaining bolts of the gangs such that the blocks may be inserted or removed by merely loosening the bolts instead of completely removing the same and without interfering with the ability of the gangs to be angle adjusted fore-and-aft. The configuration of the blocks is such that they may be stacked one upon the other to provide an increased range of depth adjustment without sacrificing rigidity of construction.
