The present invention relates to a coupling device (1) for mechanical coupling and media supply between a carrier vehicle (41) and a superstructure (42), having a coupling mechanism (10) for establishing a mechanical coupling between the carrier vehicle (41) and the superstructure (42) and a media mechanism (20) for establishing a media supply between the carrier vehicle (41) and the superstructure (42), which are operatively connected with each another via an operating mechanism (30). The coupling mechanism (10) is mounted so as to be moveable between at least one first coupling position at least partially forming the mechanical coupling and a release position releasing the mechanical coupling. The media mechanism (20) is also mounted so as to be moveable between a supply position forming the media supply and a shut-off position shutting off the media supply. The operating mechanism (30) has at least one guide means (31) for a forced guidance of the media mechanism (20) from the shut-off position into the supply position on a movement of the coupling mechanism (10) from the release position into the first coupling position. The invention also relates to an agricultural working vehicle (40) and a method for mechanical coupling and media supply between a carrier vehicle (41) and a superstructure (42).

A communication system for a working machine includes: a first communication device configured to be attached to a working device detachably disposed on a vehicle body and to transmit, to an outward, device information relating to the working device as a broadcasting signal; and a receiving device having a receiving part configured to receive the device information transmitted in the broadcasting signal.

In one aspect, a system for monitoring fluid conduit connections of an agricultural machine may include a first fluid conduit having a first coupling device, a second fluid conduit having a second coupling device, and a third fluid conduit having a third coupling device. Each of the second and third coupling devices may, in turn, include an identification device. A controller of the system may be configured to receive an input from the identification device of one of the second fluid conduit or the third fluid conduit when the respective second coupling device or third coupling device is coupled to the first coupling device. Furthermore, the controller may be configured to identify the one of the second fluid conduit or the third fluid conduit as a connected fluid conduit based on the received input.

A working machine coupler device includes a top linkage, a lower linkage, a detachable frame including a second upper coupler to be coupled to a first upper coupler, and a second lower coupler to be coupled to a first lower coupler, and a top linkage controller. The second upper coupler is coupled to the first upper coupler when the lower linkage is pivoted upward, and the first lower coupler moves toward and be coupled to the second lower coupler when a front portion of the working machine is moved upward, and the top linkage controller regulates the stretching and shortening of the top linkage to hold the detachable frame inclining backward, and allows the top linkage to be shortened until the working machine takes a working posture after the lower linkage is pivoted downward from a state where the front portion of the working machine is lifted.

An agricultural mowing device that includes a tongue configured for connecting to an agricultural vehicle, a trail frame rotatably connected to the tongue about an axis of rotation, a first trail-frame wheel and a second trail-frame wheel each being rotatably connected to the trail frame, and a cutter bar connected to the trail frame. The cutter bar includes a front end and a back end. The mowing device also includes a transport system that has a transport frame rotatably connected to the tongue and a first transport wheel and a second transport wheel each being rotatably connected to the transport frame. In the transport position, the first and second transport wheels support the trail frame. The first transport wheel is radially closer to the axis of rotation of the trail frame than the front end of the cutter bar in the transport position.

An agricultural planting system comprises an implement configured to be coupled to a work machine, row units of the implement, and first and second pairs of wheels configured to pivot and rotate to facilitate a turning operation during forward travel of the planting system. The row units are arranged in first and second ranks depending on their forward-aft placement. Furrow openers of the first rank of row units are configured to contact the ground along a first contact line, and furrow openers of the second rank of row units are configured to contact the ground along a second contact line. During a turning operation, the implement turns about a turning center axis, and the first and second pairs of wheels pivot in opposite directions, which allows the first and second contact lines to remain equidistant from the turning center axis during the turn.

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).
