摘要： A coupling arrangement for an agricultural tractor includes a drawbar having a first bar section, which is mounted in a longitudinally movable manner in a holder for attachment to an underside of a differential housing of the agricultural tractor, and a second bar section, which is situated opposite the first bar section and is guided in a longitudinally movable manner within adjacent upper and lower supporting cheeks of a coupling carrier plate provided for attachment to the rear of the agricultural tractor. The drawbar is movable into a plurality of coupling positions by longitudinal movement and can be locked therein with respect to the coupling carrier plate via at least one securing element.

摘要： An agricultural vehicle has an implement connection hitch including means for controllably moving the same relative to a rear axle of the vehicle under the direction of a vehicle control system. Under user control from a cab of the vehicle, the hitch is moved rearward from the vehicle until it reaches a first position at a chosen distance from the rear axle. Following the attachment of a known implement to the hitch, the control system retracts the hitch and implement toward the rear axle to a second position at a distance from the rear axle determined in the control system optionally at least partly on the basis of the identity of the implement. The identity of the implement may be input by the user or determined via an ISOBUS connection.

摘要： A variable length lift link for a three-point hitch has two parts which are threaded together such that one part which is formed as a spindle moves relative to the other as it is rotated. Rotation of the spindle is provided by way of an electric motor which drives the spindle through a step-down transmission, including a worm gear. The electric motor can be controlled from either the operator's station on the vehicle or from behind the vehicle in the area where an implement is attached. Limit switches control the maximum and minimum lengths of the variable length link.

摘要： A powered adjuster for a three-point hitch upper arm includes a housing adapted for rotatably supporting a drive hub having opposite ends with oppositely threaded openings for receiving the oppositely threaded connection members of a three-point hitch upper arm. A motor is supported on the housing and a drive connection is provided for rotating the drive hub in response to actuation of the motor. Finally, a coacting guide mechanism is provided on the housing and one of the connections members for preventing relative rotation between the housing and connection member while permitting relative axial sliding movement therebetween to accommodate powered extension and retraction of the upper arm by the adjuster of the invention.

摘要： A mechanical link member is provided which is easily variable in length for ease of connection yet rigid in operation by the use of hydraulic valve and screw-type adjustments. In addition to an interrupted flow position which prevents relative axial movement of the ends of the link member, the hydraulic valve has full flow and restricted flow positions to control the rate of length adjustment. A spring positions the mechanical link to a midrange position when the hydraulic valve is opened and the link ends are not attached to a load.

摘要： A hydraulically operated variable length top guide coupling member for use in three point linkage couplings for attaching agricultural implements to farm tractors includes a cylinder and a main piston with piston rod carried for longitudinal movement within the cylinder to thereby vary the length of the coupling member. Articulation means are carried at one end of the cylinder and at the other end of the piston rod for connecting the coupling member between a tractor and an agricultural implement. A pair of hydraulic lines provide communication between a source of hydraulic fluid and cylinder spaces on opposite sides of the main piston. A one-way valve is located in the path of communication between each of the hydraulic lines and the respective cylinder spaces. A control piston is carried between the two one-way valves for controlling opening of the valves. Application of hydraulic pressure to one of the hydraulic lines will open its respective one-way valve to permit hydraulic fluid to flow into the cylinder space on one or the other side of the main piston. Hydraulic pressure also acts on the control piston causing it to open the other one-way valve and permit hydraulic fluid to flow out of the other cylinder space into the other hydraulic line. Hydraulic pressure acting on the main piston will thus cause it to move within the cylinder to vary the length of the coupling member. The capability for immobilizing the main piston within the cylinder to fix the length of the coupling member to a desired position is also provided.
