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.

A cart for filling intermodal shipping containers with a bulk particulate material, such as grain, includes a hopper to receive the bulk material and a belt conveyor to deliver the material to the container. The conveyor is positioned external of the container and throws the material along an arcuate path to the opposite end of the container whereby the container is substantially filled without the need to extend the conveyor into the container. The cart is supported on wheels to be moved where needed. The cart can straddle a standard truck trailer carrying a container so that the container need not be removed from the trailer for filling. The conveyor height is variable to reach a container on a truck trailer or on the ground. The cart width can also be reduced for road transport.

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. The projection is slotted to receive a special tool for compressing the spring for standard disassembly and reassembly. The special tool also facilitates replacement of a bushing and sleeve assembly in the pivot with only partial disassembly.

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.

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.

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. The lowermost coil is maintained generally perpendicular to the centerline of the coil spring in the field-working and tripped positions so that spring buckling and spring fatigue caused by buckling are reduced or eliminated.

A wheel motor disconnect includes a rotatable plate with sized apertures including locking detents. A depressor pin extends perpendicularly from the plate. The apertures are received over shouldered spacers or guides which are connected to the wheel hub. In the drive position, the plate is located at the outermost ends of the spacers, and the pin is offset from the spring-loaded drive shaft to allow the shaft to drivingly engage a reduction gear arrangement. To disconnect the drive, the operator urges the plate axially inwardly against the bias of the drive shaft so that the apertures slide inwardly along the spacers to move the shaft out of driving relationship with the reduction gear arrangement. The operator then rotates the plate in a first direction so smaller apertures move into the shouldered area and prevent the plate from moving axially outwardly. The locking detents prevent rotation of the plate away from the shouldered area until the operator depresses the plate slightly and rotates the plate in the direction opposite the first direction.

A bypass and switch arrangement is connected to the conventional steering system on a towable vehicle. A rotary bypass valve includes two ports connected between the two hydraulic lines leading from the steering control valve to the steering cylinder or motor. The bypass valve has a normal operating position which blocks flow between the lines so that normal steering operation is provided. When the vehicle is connected for towing, the bypass valve is rotated to an open towing position to permit free flow of fluid between the ports and lines so that fluid may move freely to and from the steering motor or cylinder. If a steering cylinder is used, a third port on the valve is connected to the oil cooler on the vehicle and opens the lines to reservoir through the cooler to accommodate the deficient or excess flow from or to the cylinder which results from the difference in effective area on opposite sides of the ram. A switch connected between the switched power supply and an electric shut-off valve on the vehicle engine injector pump is responsive to movement of the valve for disabling the engine when the valve is in the towing position. Before the engine can be restarted after towing, the valve must first be moved back to the operating position wherein normal steering and pump operation is enabled.

A combination wheel shield and ladder for an agricultural vehicle such as a sprayer includes a deformable plastic body with a profile designed to control the path of deflection and to return the body to original shape after deflection. The shield is mounted on a steel framework also designed to help control deflection and assure return to the original shape. A bail limits maximum shield deflection and increases the strength of the framework. A ladder is incorporated into a plastic wheel shield extension A combination handle-step structure located above the wheel and special platform structure located on the drop axle provide convenient access to the operator's station for all adjusted positions of the drop axle.
