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 power lift for an agricultural tractor includes a supporting structure configured to be mounted on the agricultural tractor. A left lower link, a right lower link, and an upper link are coupled in a pivotally movable manner, wherein the left and the right lower links and the upper link include coupling elements for attachment of an agricultural attachment. The left and the right lower links are rotatably coupled to one another via a lifting shaft, the lifting shaft being aligned with a lower link pivot axis. The left and the right lower links are pivotable by an actuating element which runs between at least one of the lower links and a support point of the supporting structure jointly about the lower link pivot axis in relation to the supporting structure.

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.

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.

A mechanical system attaches to a tractor and, upon activation of a hydraulic ram, rotates implement-engaging implement lift hooks to rotate an attached agricultural implement upwards towards 90 degrees for inspection and maintenance. The system can be secured in its raised and rotated position via a locking pin. The implement is returned to its original position through removal of the locking pin, reversal of the hydraulic ram and disconnection of the implement lift hooks.

A three-point hitch hookup assist system may include a three-point hitch system. The three-point hitch system may include a lower link having a first connection about which the lower link pivots and an implement connector, a powered actuator to pivot the lower link, a first sensor coupled to the lower link to output signals indicating a manual force applied by an operator to the lower link, and a controller. The controller may output control signals to the powered actuator to cause the powered actuator to apply an assist force to the lower link based upon the sensed manual force.

A method for adjusting an orientation angle of an agricultural implement includes arranging a hitch such that an upper link and at least one lower link is articulated to a support structure of the utility vehicle, and adjusting the orientation angle based on a target length of the upper link. The target length of the upper link is determined as a function of the orientation angle and as a function of a lower link angle.

A tractor with at least one lifting mechanism that has an upper link and lower links and actuators associated therewith, at least one attachment adapted to the lifting mechanism, and a driver assistance system is disclosed. The driver assistance system optimizes the operation of the tractor and has a computing unit, a memory unit and at least one input interface. The computing unit processes information generated by machine-internal sensor systems, external information, and information that may be saved in the memory unit. The tractor and/or the at least one attachment include a control device for controlling and regulating the tractor and the attachment. The driver assistance system comprises an automatic lifting mechanism that is configured to function based on characteristics, and to optimize adjustment of at least one work parameter of the tractor depending on selectable regulation strategies and/or optimization target variables saved in the memory unit.

A vehicle attachment carrier loading guidance system may include a sensor for being supported by vehicle supporting a removable attachment having a mount interface for interacting with a mount on an attachment carrier distinct from the vehicle, wherein the sensor is output steering angle signals. The system may further comprise a controller to output presentation signals based upon the steering angle signals. The presentation signals are to generate a visual representation of a projected path of the mount interface with respect to the mount.

An agricultural implement includes a fertilizer section. The fertilizer section includes a first interface configured to engage a three-point hitch, and a second interface configured to engage an interface of a planter section. Further, the interface of the planter section is configured to engage the three-point hitch.
