The disclosure relates to a towing hitch for a work vehicle. The towing hitch includes a retaining element. A coupling member coupled to the retaining element. A guide element having at least one guide channel formed therein; wherein the guide channel is sized to receive a portion of the retaining element. An actuator coupled to at least one surface of the retaining element, wherein the actuator is arranged such that lateral displacement of the actuator moves the retaining element between a first position and a second position within the guide channel of the guide element.

A method for determining a physical parameter of an adjustable upper link of a three-point hitch during a working operation thereof includes providing a lower link of the three-point hitch and an implement attachable to the upper and lower links of the three-point hitch. The method includes generating calibration data prior to the working operation of the three-point hitch, where the calibration data defines a relationship of a length of the upper link to an upper link angle defined between the upper link and a reference line. Moreover, the calibration data is used to determine a physical parameter of the adjustable upper link during the working operation.

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.

A locking mechanism for a link assembly of a work vehicle hitch has a locking plate mounted to an upper portion of the link assembly. A collar is positioned over the sleeve and is configured to slide relative a portion of the sleeve. The collar meshes with the sleeve so as to prevent rotational movement of the upper portion of the sleeve relative the collar when the collar is adjacent the upper portion, but the sleeve can rotate relative the collar when the collar is adjacent a middle portion of the sleeve. The locking mechanism has a handle mounted on the collar that is pivotable between a locked position where the handle is generally parallel with the sleeve in which the collar is prevented from sliding relative the sleeve and a released position generally perpendicular to the sleeve in which the collar is able to slide relative the sleeve.

A method is carried-out by a controller architecture coupled to a beam assembly actuator, which is included in an articulating tongue arrangement connecting an agricultural implement to a tow vehicle. In an embodiment, the method includes: (i) monitoring, via the controller architecture, an effective tow length of an articulating beam assembly further included in the articulating tongue arrangement, the effective tow length measured along a straight line extending from a leading pivot joint of the articulating tongue arrangement to a trailing pivot joint of the articulating tongue arrangement; (ii) determining, at the controller architecture, an effective tow length target of the articulating tongue arrangement based upon operator input, sensor input, or a combination thereof; and (iii) transmitting commands from the controller architecture to the beam assembly actuator to maintain the effective tow length of the articulating beam assembly in conformance with the effective tow length target.

A conventional three point hitch of an agricultural tractor for the connection and use of working implements cultivating or excavating the earth and other duties involved in the industry of farming or grading excavation is modified by adding extending and retracting implement-actuators attachable to the existing bottom-lift-arms, therefore supplanting, but still using the existing bottom-lift-arms on the three-point hitch. The implement-actuators assist the implement in correcting the implements centerline when the tractor centerline is off a predetermined centerline path. In addition, the extending of the implement-actuators proportionally, inversely and simultaneously can correct the pivot point of the implement to match the pivot point of the tractor while the tractor performs turns during the working use of the implement.

A vehicle-to-implement hitch is provided and comprises a force transfer hitch connector adapted to provide a hitch point to which an implement can be connected. The connector is couplable to the vehicle by one or more flexible tensioning members which are, or can be moved so as to be, taut whereby to create a rigid structure comprising a hitch location such that the hitch point is movable.

A locking mechanism for a link assembly of a work vehicle hitch has a locking plate mounted to an upper portion of the link assembly. A collar is positioned over the sleeve and is configured to slide relative a portion of the sleeve. The collar meshes with the sleeve so as to prevent rotational movement of the upper portion of the sleeve relative the collar when the collar is adjacent the upper portion, but the sleeve can rotate relative the collar when the collar is adjacent a middle portion of the sleeve. The locking mechanism has a handle mounted on the collar that is pivotable between a locked position where the handle is generally parallel with the sleeve in which the collar is prevented from sliding relative the sleeve and a released position generally perpendicular to the sleeve in which the collar is able to slide relative the sleeve.

A stabilizer for an attachment device of a vehicle comprises a first adjusting element and a second adjusting element which are guided adjustably relative to one another along a longitudinal axis in order to vary the length of the stabilizer, a first connecting element on the first adjusting element for supporting the stabilizer against the vehicle, and a second connecting element on the second adjusting element for supporting the stabilizer against an element of the attachment device, the second connecting element being connected to the second adjusting element such that it can be rotated about the longitudinal axis via a screw connection for adjusting the length of the second adjusting element. The stabilizer further has a locking device, which is connected to the second adjusting element and the second connecting element, the second adjusting element and the second connecting element being connected to one another in a rotationally fixed manner in a locking position of the locking device.

An upper link for a three-point power lift of an agricultural tractor including a cylindrical connecting sleeve, a first fastening element rotated into a first open end of the cylindrical connecting sleeve and configured to be attached to the agricultural tractor, a second fastening element rotated into a second open end of the cylindrical connecting sleeve and configured to produce a releasable connection to an attachment, and a retaining bar attached to the first fastening element. The retaining bar includes a bar portion having a locking region for receiving a retaining catch and runs spaced apart along the cylindrical connecting sleeve. The retaining bar includes a support element encompassing the cylindrical connecting sleeve such that the connecting sleeve is rotationally displaceable, and the length of the upper link is varied by rotating the cylindrical connecting sleeve.
