A hydraulic system for a farm implement having wings is provided. The hydraulic system includes a wing elevation circuit operable to lower or raise the wings of the farm implement and a wing folding circuit operable to fold or unfold the wings of the farm implement. The wing elevation circuit is operable to raise or lower the wings of the farm implement. The hydraulic system further includes a hydraulic valve block assembly in communication with the wing elevation circuit and the wing folding circuit, in which the hydraulic valve block assembly is operable to control a flow of a hydraulic fluid in the wing elevation circuit and in the wing folding circuit.

A housing (100) for housing hydraulic components, wherein the hydraulic components are configured for operating a hitch mechanism of a tractor, is a single-body component that is configured to house a plurality of valve mechanism and a reciprocating piston therein. The housing (100) comprises cavities for locating valve mechanisms therein and a cylinder (110) for accommodating a reciprocating piston (210). The housing (100) together with a plurality of valve mechanisms (122, 124, 126, 128, 130, 132) disposed in corresponding cavities, forms a predetermined hydraulic circuit (1000). The hydraulic circuit (1000) has minimum number of leakage joints, minimizes number of components and therefore assembly and machining operations.

A power hoist equipment crane system to be used with a tractor roll bar, the system including a pivotable support bar configured to be substantially U-shaped having two side portions and a middle portion connecting the two side portions, a cable support member provided to the pivotable support bar and configured to support a cable from a hoist, and bracket assemblies provided respectively proximate each end of the pivotable support bar and configured to couple the pivotable support bar to the tractor roll bar in a pivoting arrangement, the bracket assemblies configured such that the pivotable support bar is pivotable between a substantially vertical stowed position when not in use, and a substantially horizontal use position in which the cable support member is positioned at a point spaced back from the tractor so as to be located over an implement that is attachable to the tractor.

A device for the steering assistance of a vehicle combination of a towing vehicle and an attached implement in which the attached implement swivels at a rear coupling point of the towing vehicle. The implement includes wheels that are arranged on opposite sides, which can be acted on by the control of corresponding individual wheel drives, independently of one another, with a drive torque. An electronic control unit applies a yawing moment to the implement by the asymmetrical control of the individual wheel drives in such a way that a transverse force exerted on the towing vehicle through the rear coupling point, builds up in the sense of the attainment of a pre-specified steering behavior of the vehicle combination.

The use of self-powered, autonomous vehicles in agricultural and other domestic applications is provided. The vehicles include a self-propelled drive system, tracks or wheels operatively connected to the drive system, a power supply operatively connected to the drive system, an attachment mechanism for attaching equipment to the vehicle, and an intelligent control operatively connected to the drive system, power supply, and attachment mechanism. The vehicle is configured to connect to the equipment to perform agricultural operations based upon the equipment. Multiple vehicles can be used in a field at the same time. Furthermore, the invention includes the ability to move one or more of the autonomous vehicles from field to field, home to field, or from generally any first location to a second location.

An arrangement for determining a plugging position of a hose coupling on a connection field includes the connection field including a plurality of coupling sockets and a plurality of hose couplings in which each of the plurality of hose couplings is coupled to a corresponding one of the plurality of coupling sockets. The at least one hose coupling includes a receiving coil and each of the plurality of coupling sockets includes a transmitting coil. A data interface is disposed in communication with the receiving coil, and an evaluation unit is disposed in communication with the data interface. The receiving coil is configured to analyze an individual identifier retrievable at the transmitting coil during connection of the at least one hose coupling to one of the coupling sockets, and the identifier is transmitted via the data interface to the evaluation unit to determine the plugging position of the hose coupling.

A link assembly for a hitch includes a first link and a second link. The second link has first and second spaced apart bores extending therethrough. A coupling member is attached to an end of the first link. The coupling member includes first and second spaced apart coupling plates. The coupling member has a load bore extending through the first and second coupling plates and has a plurality of index bores extending through the first and second coupling plates. A load pin is receivable by the load bore and the first bore, and pivotally couples the second link to the first link. An index pin is removably receivable by the second bore and a selected index bore, and the index pin is movable independently of the load pin.

A coupling mechanism controls the location of the central primary draft load transmitting fixed-length link independently of the coupler. The coupling mechanism allows for translation in at least three orthogonal directions and for rotation of two distinct planes between coupled components, thereby providing a means for lateral shifting and articulation. The coupling mechanism mitigates unexpected rotation by restricting rotation along a longitudinal axis of the fixed-length link. Rotation of the coupling mechanism is furthermore controlled by means of a indexing turntable. The orientation and the position of the coupling mechanism is therefore determinant and predictable.

An apparatus for connecting an implement to a three point hitch of mobile machinery comprises two frameworks, a first framework and a second framework. The first framework is disposed in a first plane and comprises at least two parallel, vertically-spaced apart, laterally extending rails. There are three attachments supported by the first framework for attachment to the three-point hitch. The second framework is slidable generally in the plane of the first framework and is mounted on the rails to slide laterally along the rails. At least two connectors are supported by the slidable second framework for connecting the second framework to an implement that can be pulled or pushed by the mobile machinery. A driver is connected to the first framework and connected to the second framework for driving the second framework laterally back and forth along the rails of the first framework.
