Abstract: A chain is connected at its distal end to the pin at the rod end of a cylinder on an implement lift and depth control assembly. An intermediate portion of the chain is trained around a gear which rotates about the axis of the pin connecting the base end of the cylinder to the implement frame. An adjustable length, spring-biased rod is connected to the proximal end of the chain to maintain tension in the chain and operate a single point depth control valve to establish a highly accurate and repeatable depth setting which is dependent directly on cylinder rod extension and therefore less susceptible to looseness in the implement lift system.

Abstract: A forwardly-folding, tractor-drawn agricultural implement featuring a rear center frame and a pair of wing sections that may selectively occupy operating positions in which they are horizontally and transversely alined with each other but alined in that manner forwardly of the center, rear section. This rear section carries no agricultural tools and serves basically as a rear rolling support for the implement in both its operating position and in a transport position in which the wing sections are folded forwardly along opposite sides of a central telescopic tongue or hitch by means of which the rear section is connected to and supported on a tractor. When the implement is in its transport or folded position, the overall length of the machine may be shortened to bring the rear support wheels closer to the tractor.

Abstract: An implement hitch assembly is described that can be removably attached to an implement and to a towing vehicle. The hitch assembly includes apparatus by which the implement frame is allowed to pivot freely about a selected axis relative to the towing tongue frame when the implement is in a lowered, operative position. Pivotal motion is transferred to a different pivot axis on the hitch assembly when the implement is elevated. The former pivot axis is locked in the raised position of the implement and selected resistance to pivotal motion about the other axis is provided to enable safe transport of the implement.

Abstract: Two gang disc harrow units are pivotally joined near corresponding ends by a vertical axis hinge coupling. Near their opposite corresponding ends, the harrow units are connected by a collapsible toggle linkage which operates in a horizontal plane under influence of a power cylinder, whereby the harrow units can be positioned at a prescribed angle for working the soil and in parallel relationship for transport. Two transport wheels are pivotally attached to the rear harrow unit on transverse pivot axes which are parallel to the rear unit. Power cylinders interconnecting these wheels with the rear harrow unit are operable to lower and raise the wheels for lifting and lowering the rear unit. The front harrow unit has a pivotal connection with a drawbar which in turn is coupled through a draft tongue with the hitch of a towing or transport vehicle. Another power cylinder connected between the pivoted drawbar and front harrow unit is operable to lift and lower the front unit.

Abstract: A control for selectively setting the operating depth of a ground working agricultural tool without changing the elevated height of the tool when in the transport position. The control includes a ground supported wheel frame pivotally mounting a tool frame. The tool frame is pivoted on the wheel frame between a raised inoperative position and a lowered operative position by operation of a cylinder assembly. The cylinder assembly is pivoted at one end to the tool frame. Its remaining end is connected to a bracket on the wheel frame. The bracket includes a slot, slidably mounting the remaining end of the cylinder. The slot is aligned along an arc centered on the pivot axis of the cylinder at its one end when the tool frame is elevated to the inoperative position. The slot is inclined upwardly toward this pivot axis as the tool frame is lowered to the operative position.
