A system and method for hitching, using a swivel pin, a tractor with a drawbar and a towable implement comprise a handheld tool for inserting the swivel pin through a pin-receiving portion of the drawbar and a hitch tongue of the implement when arranged in an aligned coupling configuration. The handheld tool has an upper end configured for gripping by a user and a lower end configured to removably receive the swivel pin. Furthermore, the handheld tool is configured to extend from the operator cab of the tractor to the pin-receiving portion of the drawbar of the tractor so that the handheld tool is usable by the operator to hitch the tractor and the implement with the swivel pin without leaving the operator cab. A novel swivel pin with arms for mating engagement with a receptacle in the lower end of the tool enables the pin to be rotationally releasably secured therein.

The disclosure relates to a coupling device. This is known below as a docking receptacle. The docking receptacle comprises an approximately U-shaped pilot centring device with an insertion trough tapering approximately conically in an insertion direction for pre-centring a docking insert designed to mate with the docking receptacle, at least a first and a second centring device, with the first and the second centring devices each comprising two coupling elements which are designed for centring a docking insert with respect to the docking receptacle along four centring axes in an insertion direction, and wherein a drawing-in device with two hydraulically actuated drawing-in or capture hooks are provided. The disclosure further relates to a docking insert. This comprises a pilot centring body having an insertion tray tapering approximately conically in an insertion direction and extending in the horizontal direction, at least a first and a second centring device, wherein the first and the second centring devices each comprise at least two coupling elements and/or coupling counter-elements which are designed for centring the docking insert with respect to a docking receptacle along four centring axes extending in an insertion direction and two capture pins extending transversely to the insertion direction in the horizontal. According to the disclosure, a coupling assembly or a docking assembly is, furthermore, provided comprising the docking receptacle and the correspondingly mating docking insert.

A conversion unit is used for indirect attachment of a mounted implement to a working machine. The mounted implement features a single-point connector, while the conversion unit features both a multi-point mounting arrangement configured for removable coupling to a multi-point attachment arrangement on the working machine, and a single-point coupler configured for removable coupling to the single-point connector of the mounted implement. With the conversion unit in an operating position attached to the attachment arrangement of the working machine, coupling of the mounted implement to the conversion unit via engagement of the single-point coupler with the single-point connector indirectly attaches the mounted implement to the working machine in a mounted position thereon. A shared upright axis of the single-point coupler and single-point connector allows angular adjustment or free-swiveling of the implement about the shared axis when a corresponding lock pin is withdrawn from locking position that blocks such movement.

A manual locking subassembly for a loader system of a utility vehicle includes an actuator manually operable from an operator cab of the vehicle and a mechanical linkage extending from the actuator and affixed to a loader attachment carrier rotatable about an axis. Manipulation of the actuator in a first direction moves a linkage member of the mechanical linkage from a first position in which a loader attachment implement is uniformly movable with the attachment carrier to a second position in which the loader attachment implement is non-uniformly movable with the loader attachment carrier.
