Disclosed herein is a vehicle (1)—preferably a tractor—with a trailer (2) operatively connected thereto with a cardan (3), said cardan (3) comprising a power take-off, said power take-off being switched off when said cardan (3) builds with said vehicle (1) and/or with said trailer (2) an angle (ϵ) smaller than a first threshold value (a) and/or larger than a second threshold value (β) and being switched on when said angle (ϵ) exceeds again said first threshold value (β) thanks to suitable actuators, including detection means of the angle formed between the cardan (3) and said vehicle and/or trailer. According to the present invention, said angle (ϵ) is detected by a detector consisting of a magnetic device (4) placed on the trailer (2) or the vehicle (1) and an electronic compass (5) placed on the vehicle (1) or on the trailer (2). Preferably, the angle (ϵ) insisting on the cardan (3) is obtained according to the formula: ϵ=180−Y−arcsen (l/m sen y) (3) where y is the angle the compass (5) forms with respect to the straight travel with the magnet (4), I is the distance between the cardan (3) and the compass (5), m is the distance between the cardan (3) and the magnet (4).

A system for coupling an implement to a work vehicle includes a controller comprising a memory and a processor, wherein the controller is configured to receive a first signal indicative of a distance between a protrusion of a connector assembly of an arm of the work vehicle and a receiver assembly of the implement. While the first signal is less than a first threshold, the controller is configured to instruct a first actuator to rotate the connector assembly of the work vehicle, instruct a drive system to move the work vehicle toward the implement, instruct a second actuator to lift the arm of the work vehicle, or a combination thereof, such that the protrusion of the connector assembly engages a recess in the receiver assembly.

An articulated towing apparatus pulls a rotary driven implement in a forward working direction across a ground surface behind a towing vehicle. The apparatus includes a longitudinal frame pivotally connected at a leading end to the towing vehicle by a coupling frame and pivotally connected at a trailing end to a wheeled frame that supports the implement thereon. The coupling frame defines lateral and vertical pivot axes between the longitudinal frame and the towing vehicle. A drive line, connected between a power take-off of the towing vehicle and the implement, includes (i) a longitudinal drive shaft extending at a downward slope, and (ii) an output for connection to the implement that is rotatably supported on the wheeled frame.

An attachment (1) for attaching to a towbar (3) of a towable apparatus (5), for example, a mower for hitching the towable apparatus (5) to either an agricultural tractor or a road vehicle comprises a mounting shaft (10) for securing to the towbar (3), and carrying a first gearbox (12). A second gearbox (14) is pivotally coupled to the first gearbox (12) about a vertical pivot axis (15) through which drive is transmitted from the second gearbox (14) to the first gearbox (12). A carrier housing (24) is rigidly secured to the second gearbox (14) and carries a first hitch (30) for hitching to a complementary hitch mechanism of a road vehicle, and a second hitch (38) for coupling a tractor (7). The second gearbox (14) is pivotal relative to the first gearbox (14) about the main pivot axis (15) between a first state with the first hitch (30) ready for hitching to the road vehicle, and a second state with the second hitch (38) ready for hitching to the tractor (7).

A tractor hydraulic adaptor, system and process to hydraulically power a hydraulic attachment on a tractor is disclosed. The hydraulic adapter includes a hydraulic intensifier powered by a tractor's power take off shaft to drive a hydraulic attachment coupled to a tractor's front-end loader. The hydraulic intensifier draws at a low-pressure hydraulic fluid and feeds the hydraulic fluid at a higher pressure to the hydraulic attachment.

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.
