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 working machine has a display device including: an area display portion to display a setting area for setting the first priority value, the second priority value, and the third priority value; a first axis display portion including a first scale portion indicating the first priority value depending on a distance from the reference point; a second axis display portion including a second scale portion indicating the second priority value depending on a distance from the reference point; a third axis display portion including a third scale portion indicating the third priority value depending on a distance from the reference point; and a marker display portion to be indicated in a partial area corresponding to at least two of the first axis display portion, the second axis display portion, and the third axis display portion.

A work vehicle includes a lifting mechanism to control at least one of a height and a posture of a work machine connected to the work vehicle. The lifting mechanism is able to control at least one of the height and the posture by using a hydraulic drive. The work vehicle includes an oil-temperature acquirer to acquire an oil temperature to be used for the hydraulic drive, a maximum oil amount setter to set a maximum oil amount according to the oil temperature acquired by the oil-temperature acquirer, the maximum oil amount being a maximum value of a supply amount of oil used to drive the hydraulic drive, and a hydraulic drive controller to control the hydraulic drive below the maximum oil amount set by the maximum oil amount setter.

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.

An air leaf stripping system and an agricultural machine equipped with such system. The system is used in viticulture for stripping leaves from vinestocks. The system can be mounted on a tractor and includes adjustment mechanism consisting of a rotary joint and coupling for rotating a housing and includes an arm that has a main longitudinal axis and includes the supply line and an attachment part intended to be mounted on the agricultural machine directly or via a frame. The supply line-is guided along the attachment part and connected to the leaf stripping members through a junction in the housing via the rotary joint. The rotating member being arranged so that the housing can be rotated about a first axis passing through the junction and substantially perpendicular to the main longitudinal axis of the arm, between at least two separate angular positions relative to the first axis.

An attachment system for an agricultural vehicle including a feeder housing and a header. The attachment system includes at least one feeder connecting member configured for being located on and movably connected to the feeder housing, and at least one header connecting member configured for being located on the header. The at least one feeder connecting member is automatically connectable and securable to the at least one header connecting member as the feeder housing lifts the header.

A method for controlling a hydraulic top link of a three-point linkage on a piece of accessory equipment coupled to a tractor includes providing the top link coupled between a first location on the tractor and a second location on the accessory equipment. The method includes defining an extension position of the top link as a distance between the first location and the second location, where the extension position is adjustable within a predetermined adjustment range. The method further includes determining a force acting on the top link and adjusting the extension position of the top link by a control unit as a function of the force acting on the top link.

An actuator assembly for use with a quick coupler. The actuator assembly includes a manual actuator assembly, a control rod coupled to the manual actuator assembly, and a remote actuator assembly coupled to the control rod. The manual actuator assembly is configured to be hand actuated from outside of the quick part coupler, and configured to move the latching assembly from a locked position to an unlocked position via the control rod. The remote actuator assembly is configured to be remotely actuated from outside of the quick coupler, and configured to move the latching assembly from the locked position to the unlocked position via the control rod.

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.
