Abstract: A seeding machine comprises a main frame segment and two wing frame segments. In its working configuration the wing frame segments extends transversely. In its transport configuration the wing frame segments are folded forwardly. The wing frame segments are provided with planting units that are mounted to the wing frame segments by pivot arms that extend downwardly and rearwardly. The pivot arms are pivotally mounted to the wing frame segments by a rock shaft. The rock shaft is provided with an actuator bell crank that is coupled to a linear actuator for rotating the rock shaft relative to the wing frame segments. The pivot arms have a working position, wherein the planting units are in their working position, and a transport position, wherein the planting units have been pivoted on their noses into their substantially vertical transport position.

Abstract: A series of thin shims with concave profiles matching the cylinder rod is supported from the cylinder. A carrier mechanism attached to either the rod end or cylinder barrel supports a plurality of shims that can be pivoted between storage positions and stop positions. A pivoting and spring loaded latching arm works in conjunction with notches on the shim profile to lock individual shims in either the working or the storage position. Multiple shim stack operating ranges are provided by insertion of thicker shims between the main shim pack and the mating part. The mating part can be a cylinder rod end or cylinder rod guide, depending upon the shim pack carrier mechanism.

Abstract: A hydraulic hose holder comprises a vertically extending standard having a mounting plate, an arched clamping plate, arched resilient insert conforming to the clamping plate, and a circular disc. The arched clamping plate is secured to the mounting plate by screw jacks. The resilient insert is located between the mounting plate and the clamping plate. The resilient insert is provided with a circular opening having a series of radially extending slots. Each of the radially extending slots is provided with an enlarged opening for holding a hydraulic hoses or an electrical line. The hoses and electrical lines snap into the enlarged openings through the slots. The circular disc is placed in the circular opening trapping the hydraulic hoses and electrical lines in the enlarged openings.

Abstract: A seeding machine comprises a main frame segment and left and right wing frame segments. In its working configuration the wing frame segments extend transversely. In its transport configuration the wing frame segments are folded forwardly. The wing frame segments are provided with a rear rank of planting units that are mounted to the wing frame segments by pivot arms that extend downwardly and rearwardly. The pivot arms are pivotally mounted to the wing frame segments by a rock shaft. The rock shaft is provided with an actuator bell crank that is coupled to a linear actuator for rotating the rock shaft relative to the wing frame segments. The pivot arms have a working position, wherein the planting units are in their working position, and a transport position, wherein the planting units have been pivoted on their noses into their substantially vertical transport position to reduce the transverse transport width of the seeding machine.

Abstract: A case drain coupler mounting plate is mounted to the frame of the seeding machine. The case drain hydraulic coupler is secured to the case drain coupler mounting plate when it is not coupled to a tractor. The mounting plate is provided with a keyhole-shaped mounting aperture having an enlarged upper opening and a narrow channel projecting downwardly from the enlarged opening. The case drain hydraulic coupler is provided with a circumferential groove that engages the narrow channel in the keyhole shaped slot. A backing plate is mounted to the mounting plate at a fixed distance from the mounting plate. The backing plate engages the case drain hydraulic coupler and overcomes the biasing force to open the check valve. With the check valve open the case drain line provides a drain path for hydraulic fluid from the case drain.

Abstract: A lift and rotate agricultural implement frame comprises a main frame having a lift tube and a carrier frame slidably mounted to the lift tube. The lift tube comprises a vertically extending main support tube having planar surfaces and a corrosion resistant exterior sleeve. The corrosion resistant exterior sleeve comprises corrosion resistant plates corresponding to the planar surfaces of the main support tube. Each of the plates has an interior surface and an exterior surface. At least one of the corrosion resistant plates adjoins another plate. One of the adjoining plates is provided with an overhang that extends past the exterior surface of the other plate of the pair. The plates are fillet welded to one another between the overhang and the other plate. The plates are also provided with oblong openings having oblong edges. The oblong edges are fillet welded to the main support tube to couple the sleeve to the main support tube.

Abstract: A flexible frame structure for an implement includes a wing frame section with several fore-and-aft spaced, transversely extending rank tubes that are connected to surrounding support structure with conventional, non-resilient pin joints for rotation about a fore-and-aft extending horizontal rank axis. A transversely extending rear rank tube is rigidly connected to a fore-and-aft extending caster wheel support frame which extends forwardly above the ends of the rank tubes. A caster wheel projects forwardly from the end of the support frame out of interfering relationship with the forward tool-carrying rank. The rear rank tube and caster wheel support frame define a rigid L-shaped member which is connected to the adjacent frame section by a conventional pin and pivot structure for rotation about a first axis corresponding to the rank axis, and a second axis perpendicular to the forward direction.

Abstract: A stroke limiting structure for use with a lift control system on an implement includes a reciprocating link operably connected to a hydraulic cylinder and to a lift wheel assembly on an implement frame section. The link is connected by a lost motion connection to depth gauging structure including gauge plates pivotally supported on a carrier. The plates are rotatable between disengaged and engaging positions without need for tools and are maintained together on the carrier to eliminate loose parts that could be misplaced or lost. The plates in the engaging position determine the lowermost position of the implement and provide a positive mechanical stop for the implement to eliminate depth control problems caused by cylinder leakage or the like. The lost motion connection eliminates unwanted movement of the plate carrier and facilitates gauge plate pivoting for depth adjustments.
