Abstract: An implement/vehicle hitch system for coupling implements to a utility vehicle includes two hydraulic cylinders for adjusting the position of the implement. The hydraulic cylinders are connected to a pair of motor/pump units which cause the hydraulic cylinders to operate in a synchronous manner.

Abstract: A hitch control system controls a hitch for coupling an implement to a utility vehicle. The hitch includes longitudinally adjustable coupling elements operable to shift or pivot the implement in a lateral direction relative to the utility vehicle. A sensor, such as a wheel steering angle sensor, senses a parameter associated with lateral or turning movements of the vehicle. A control unit automatically adjusts the length of the coupling elements as a function of the sensor signals so that the position of the implement relative to the vehicle is adapted to the curved path. This reduces the outer radius of the area over which the vehicle and implement travel when traveling along a curved path and helps avoid collisions with objects.

Abstract: A coupling system couples an implement to a utility vehicle, such as an agricultural or industrial vehicle, and includes a vehicle-mounted coupling frame and an implement-mounted coupling frame. The position of the vehicle-mounted coupling frame is adjustable by an adjustment mechanism. A position sensor senses the position of the implement-mounted coupling frame. An analysis unit determines the position of the implement-mounted coupling frame relative to the vehicle-mounted coupling frame. A control unit calculates a coupling motion path of the vehicle-mounted coupling frame. In response to a starting signal, the control unit causes the adjusting mechanism to move the vehicle-mounted coupling frame along the coupling motion path.

Abstract: A control lever controls movement of a system to be controlled. The control lever includes a manually operable handgrip attached to a platform. At least six connecting elements are arranged between the platform and a fixed console. Length sensors sense the length of the connecting elements, and/or force sensors senses forces acting on the connecting elements. A control unit evaluates the sensor signals and generates a control signal for controlling movement of the system. The connecting elements are be arranged in the form of a hexapod. The connecting elements may be telescoping members or rigid fixed length members.

Abstract: A chopper arrangement for a harvesting machine comprises a body that is rotated in a predominantly vertical axis of rotation. The body is provided with a plurality of radially extending knives that are axially distributed along the body. The knives have radially outer ends that are arranged in a conical shape. In this way the knives at the first end having a smallest radial extension are rotated at a slower circumferential speed than knives having a larger radial extension.

Abstract: The invention is directed to a combine having a chopper arrangement for receiving and chopping harvested crop material that has been threshed and separated. The chopper arrangement comprises a web wheel disk having knives entrained thereon that cooperate with a stationary shear bar to chop the harvested crop material that has been threshed and separated.

Abstract: An implement interface for mounting on a chassis of a vehicle includes a telescopic boom pivotally coupled to the vehicle chassis so that the boom is pivotal about an essentially horizontal axis. The boom includes a housing which is pivotally coupled to the vehicle chassis and an arm which is slidably received by the housing. A carrier is mounted on a free end of the arm. A three-point hitch is mounted on the boom and has lower links coupled to the carrier, has an extendable upper linkage coupled to the boom, a lifting arm coupled to the carrier, a lifting brace connecting the lifting arm to one of the lower linkages, and a lift cylinder for vertically pivoting the lifting arm. A locking mechanism fixes the boom relative to the chassis. A hydraulic cylinder unit is coupled to the sliding arm and operable to move the sliding arm in a longitudinal direction. A pressure-operated piston/cylinder unit is coupled between the housing and the chassis and is operable to vertically pivot the boom.

Abstract: A coupling device couples a vehicle, such as an agricultural or industrial vehicle, to an implement, such as trailer. The device includes a three-point implement interface with a coupling frame which is movably mounted on a chassis of the vehicle. A one-point coupling is mounted on the coupling frame. The coupling frame may be connected to the vehicle chassis by means of adjustable length connecting elements, which are preferably arranged in the form of a hexapod.

Abstract: A hitch mechanism for coupling an implement to a utility vehicle includes a coupling frame and six variable length links. The frame has couplers for coupling to the implement. Each link has a first end coupled to the vehicle and a second end coupled to the coupling frame. The links are preferably arranged in the form of a hexapod, so that, in addition to the functions of known three-point hitches, the implement may be steered sideways or shifted sideways, and so that the motion of the coupling frame has six degrees of freedom.

Abstract: The invention relates to a sensor for determining the structure-borne sound vibrations generated by the impingement of grains on a pulse detector in an agricultural machine for harvesting crops and to a device for operational monitoring of the sensor and improved signal evaluation.Such sensors are used to monitor threshing and separating performance at various points in a harvesting machine. Depending on the area of application, various forms of a pulse detector are used. These can have the shape of a plate, a tube, a rod or other similar profiles. Attached to these detectors are vibration detectors. A particularly strong connection between the vibration detector and the pulse detector is achieved by using a piezo-ceramic vibration sensor and its attachment by means of a screw connection.
