Abstract: A grain cart or similar device for receiving and moving granular agricultural product from a harvester includes bulk filling structure for directly loading an elongated intermodal container. The cart has a frame supported on wheel structure at generally a constant height relative to the surface of the ground, and a grain tank is fixed to the frame. A lift assembly connected to the cart frame adjacent the tank supports a vertically adjustable high speed filling conveyor above the cart hitch. The filling conveyor is operable at a speed sufficient to throw the material along an arcuate path through a side opening in the intermodal container towards the opposite end of the container. The intermodal container can be filled directly from the grain cart with the end of the filling conveyor located outside of the container.

Abstract: A lift system includes parallel connected cylinder circuits with cylinders mechanically tied together on a first lift wheel arm. The base end of a third cylinder connected to a second lift wheel arm is connected in parallel with the pair of cylinders. The rod end of the third cylinder is constrained for movement with the rod end of a fourth cylinder also connected to the second wheel arm. The rod end of one of the pair of cylinders is connected in series with the base end of the fourth cylinder to thereby constrain the third and fourth cylinders on the second lift wheel arm to move in unison with the pair of cylinders on the first lift wheel arm. Series cylinder circuits move the wing cylinders in unison with the main frame cylinders to keep the implement level. The hydraulic circuit is also plumbed to retract outer wing wheels during wing fold operations to eliminate outer wing wheel interference.

Abstract: Sweep retaining structure includes a spring wire retainer with a base supported in a groove on the underside of the wedge support which mates with a stem portion of the sweep. The wedge support is apertured, and a central curved portion of the retainer passes through the aperture and supports a sweep-contacting end above the surface of the wedge support. The end is biased toward a contact area on the sweep to engage the area and eliminate sweep loss problems by preventing the sweep from slipping downwardly from the mounted position. To remove the sweep, a tool is inserted through the slot to depress the retainer end, and the sweep is forced off the wedge support. A raised area on the sweep directs soil away from the retainer and contact area to reduce wear and eliminate depression of the end during operation. The underside of the raised area positions the wire end and provides bend-resisting support for the wire.

Abstract: Sweep retaining structure includes a retainer having a contact end biased towards the sweep. The sweep includes two or more spaced end-receiving areas to accommodate changes in the mounted sweep position. In one embodiment, the retainer is a wire made of spring steel having a contact end biased against the underside of the sweep. In one embodiment, the underside of the sweep includes a series of stepped portions. As the sweep is forced on the adapter on the shank, the contact end springs into retaining position on the stepped portion that aligns with the spring end when the sweep is in the mounted position. The sweep can be attached loosely by hand in an initial position with operating forces moving the sweep to a wedge locked position.

Abstract: An implement frame supported by hydraulically controlled lift wheels includes accumulator structure which is selectively connectable by valve structure to the lift cylinder circuit to control flow between the cylinder and accumulator according to implement status. For transport, the valve structure is opened for absorption of shock loads as the lift wheels move over obstructions and surface irregularities. For working in the field, the valve structure is closed to provide stable lift and precise depth control functions. The valve structure can be operated manually or automatically in response to vertical frame movement. In one embodiment, proportional valves are connected to an implement control unit for active suspension control which varies with changing transport conditions. A similar accumulator structure is provided for the hitch weight transfer system.

Abstract: A spring trip standard for a tillage implement includes a coil spring freely and solely compressed between an upper spring-abutting surface on the mounting bracket and a lower spring-abutting surface on a casting which is connected by a transverse pivot to the mounting bracket. A tool supporting shank is bolted to the casting and biased downwardly into a ground working position by the spring. The casting includes an integral stop extending forwardly from the pivot. The stop contacts the bottom of the bracket when the shank is in the ground working position so that a tension link between the bracket and casting is eliminated. A spring guide through the coils is also obviated. A relatively high initial trip force prevents unwanted tripping of the shank and prevents looseness in the shank pivot so the lateral position of the tool is maintained. The spring-abutting surface on the casting includes a spring receiving projection to help maintain the spring position relative to the shank.

Abstract: A spring trip standard for a tillage implement includes a coil spring freely compressed between an upper spring-abutting surface on the mounting bracket and a lower spring-abutting surface on a casting which is connected by a transverse pivot to the mounting bracket. A tool supporting shank is bolted to the casting and biased downwardly into a ground working position by the spring. The casting includes an integral downstop extending forwardly from the pivot. The downstop contacts the bottom of the bracket when the shank is in the ground working position so that a tension link between the bracket and casting is eliminated. A positive upstop limits upward pivoting of the casting to prevent spring breakage or permanent deformation of the spring. Shoulder areas on the casting contact rear edges of the mounting bracket to limit upward pivoting.

Abstract: A disk scraper system for an agricultural implement includes a tubular member slidably supported by the implement frame adjacent a gang assembly having a plurality of disks. Scrapers are fixed to the member and project into scraping relationship with the disks to remove dirt and debris from the surfaces of the disks. A hydraulic cylinder is connected between the frame and the tubular member and connected through a pressure control valve assembly to a source of fluid under pressure to bias the member so the scrapers are urged into scraping relationship relative to the disks. The pressure control valve assembly may be remotely adjustable to vary the scraper pressure on-the-go as conditions change. The system maintains the selected scraper bias even as the gang assembly moves vertically and from side to side relative to the frame with changing contour and soil conditions.

Abstract: A spring trip standard for a tillage implement includes a coil spring compressed between an upper spring-abutting surface on the mounting bracket and a lower spring abutment surface on a casting which is connected by a transverse pivot to the mounting bracket. The casting includes an integral stop extending forwardly from the pivot and contacting the bottom of the bracket when the shank is in the ground working position so that a tension link between the bracket and casting is eliminated. The casting includes a spring abutment surface having a first portion which extends generally perpendicular to the spring axis to support the lowermost end of the spring when the shank is stopped in the normal working position. The opposite side of the spring abutment surface is angled relative to the first portion, and the lowermost coil of the compressed spring, when the standard is in the tripped position, abuts the opposite side to maintain the spring in a non-buckling state.
