A working vehicle includes: a vehicle body; a lifting device provided on the vehicle body; a first setting member to set a reference position in a height direction of the working device coupled to the lifting device; a lifting operation member to be operated to raise and lower the lifting device; a first lifting control unit to perform reference lifting control to raise or lower the lifting device so that the working device is located at the reference position; and a second lifting control unit to stop the reference lifting control when the lifting operation member is operated during work by the working device and to raise or lower the lifting device in response to the operation of the lifting operation member. The first lifting control unit performs control to return the lifting device to a position corresponding to the reference position when the operation of the lifting operation member is released after the reference lifting control is stopped.

A transport assembly for a harvesting head that includes head connector arms, a transport axle, and a coupling system with a latch actuator, and first and second latch mechanisms coupled to the latch actuator and located at opposite ends of the transport axle. The transport assembly functions in working and transport modes. In the working mode, the first and second latch mechanisms latch the first and second head connector arms to the transport axle to latch the harvesting head to the transport axle. When the latch actuator is activated, the first and second latch mechanisms release the first and second head connector arms from the transport axle to allow the harvesting head to separate from the transport axle. When the latch actuator is not activated, the first and second latch mechanisms can be biased to remain latched.

A towed agricultural implement including a first headstock element for connection to a towing vehicle, a second headstock element supporting a chassis member provided with a plurality of working implements, a pivot pin for connecting the first headstock member and the second headstock member and defining a horizontal axis of rotation between the first headstock member and the second headstock member, in which the second headstock member has a lateral centre of gravity offset from the axis of rotation. A compensating structure is provided between the first headstock member and the second headstock member to offset the unbalanced loads caused by the lateral centre of gravity being offset from the axis of rotation.

A system is suitable for connecting multiple implements to a three-point hitch of mobile machinery for controllable side-shifting movement of the connected implements. The system comprises first, second and third apparatuses, each apparatus comprising a first framework, a slidable second framework laterally slideable relative to the first framework, at least one connector supported by the slidable second framework for connecting the slidable second framework to one of the implements, and at least one driver connected to the first framework and the slidable second framework for driving the slidable second framework laterally back and forth relative to the first framework. The second apparatus is attached to one side of the first apparatus and the third apparatus is attached to the other side of the first apparatus.

An attachment assembly for connecting an agricultural implement to a tractor. The attachment assembly comprises a tractor-side frame configured to extend from a rear of the tractor, and an implement-side frame configured to be removably attached to the implement. The implement-side frame is configured to rotate with respect to the tractor-side frame.

An agricultural machine has a linkage system for hitching of an implement and an additional axle mounted to the linkage system. The linkage system includes at least one lift arm adjustably mounted to the chassis at an inner end and carrying a fastening device at an outer end. The additional axle is connected to at least one lift arm inboard of the fastening device. The linkage assembly may be a three-point linkage assembly having two lower lift arms, the additional axle being mounted between the lower lift arms.

A hitch assembly may comprise a pair of fixed actuator support brackets that are mounted to a vehicle frame and a pair of modular actuator connection brackets that are connected to the pair of support brackets. The hitch assembly may further comprise a pair of lower links that are connected to the pair of fixed actuator support brackets and a cross bar that connects a first lower link of the pair of lower links to a second lower link of the pair. The hitch assembly may further comprise a pair of electric linear actuators that are connected to the pair of modular actuator connection brackets and the pair of lower links, as well as a top link that is at least pivotally connected to a top link bracket on the vehicle frame, in which the lower links are is moved by extension or retraction of the connected electric linear actuators.
