A towing apparatus for agricultural machines of the type of balers and round balers, which comprise at least one device for gathering previously-cut agricultural products, of the type of grass, wheat, maize, hay, forage, and the like, and a chamber for the accommodation and compression of the agricultural products, which are received from the gathering device, for the formation of a bale; the towing apparatus comprises at least one first member, which can be coupled to the agricultural machine and is associated with a second member; the second member is in turn associated with a third member, which can be coupled to a tractor for towing the agricultural machine; either or both of the first member and the second member is controlled by at least one respective actuator, for the movement of the agricultural machine at least partially independently of the advancement of the tractor.

A working vehicle comprises a vehicle body, a quick hitch, a working implement connected to the vehicle body via the quick hitch, and a linkage interposed between the quick hitch and the vehicle body. The linkage is movable to raise and lower the quick hitch so as to locate the quick hitch at an optional height. The quick hitch can be inclined to a certain degree in a pitching direction of the vehicle body at the optional height defined by the linkage.

An adjustable three point hitch system includes a frame that may be removably coupled to a tractor. The frame has a selectively adjustable width. Thus, the frame may be coupled to implements having a variety of widths thereby facilitating the tractor to draw the implements. A spreading unit is coupled to the frame and the spreading unit may be manipulated. The spreading unit urges the frame between a minimum width and a maximum width.

A three point connection dolly for connecting an articulating tractor to a plow includes a dolly having a three point plow hitch configured to connect to a plow. The dolly also includes a chassis frame with a tractor hitch extension configured to extend the three point plow hitch a distance from the articulating tractor sufficient to allow rear wheels of the articulating tractor to fully turn.

A working machine includes a machine body, a lifting device to link a working device to the machine body, the lifting device being capable of moving up and down with the working device between a grounding state in which the working device is in contact with a ground and an ungrounding state in which the working device is out of contact with the ground, and an automatic travel controller to cause the machine body to perform automatic travel according to a planned travel route. The automatic travel controller includes a lifting controller to control the lifting device to move up with the working device from the grounding state to the ungrounding state, and cause the machine body to turn or travel rearward after the lifting controller controls the lifting device to move up with the working device from the grounding state to the ungrounding state.

A mobile communications station may include a supporting frame including an interface for mechanical coupling to a vehicle for transporting the mobile communications station, wherein the interface includes fastening points for attachment of a three-point hitch; a first antenna mounted on the supporting frame to facilitate communication with mobile devices; and a second antenna mounted on the supporting frame to facilitate communication with a distant location, wherein the first antenna and the second antenna are to facilitate a bidirectional communication link between the mobile devices and the distant location.

A quick coupler for a three-point hitch includes a cross-beam configured to extend between a first main support and a second main support. The cross-beam is configured to support an anti-rotation hook. In addition, the cross-beam includes a top member extending along a length of the cross-beam and a bottom member extending along the length of the cross-beam. The top member and the bottom member are spaced apart to form a hollow portion between the top member and the bottom member. Furthermore, the cross-beam includes at least one cross-member extending from the bottom member to the top member within the hollow portion.
