Systems, methods, and apparatus for shifting weight between a tractor and toolbar and between sections of the toolbar and for folding a toolbar between a field position and a transport position.

An implement for traversing a field includes a main frame section and a frame wing section pivotally coupled to the main frame section. The frame wing section includes a wing wheel assembly for supporting the frame wing section. A hydraulic control system includes a pressure source, a control valve fluidly coupled with the pressure source, and an actuator assembly fluidly coupled to the control valve. The implement further includes a controller electrically coupled with the control valve. A wheel force sensor is configured to detect an amount of force on the wing wheel assembly and communicate the amount of force to the controller. The actuator assembly is coupled between the main frame section and the frame wing section. The controller operably controls movement of the control valve to actuate the actuator assembly and adjust the amount of force on the wing wheel assembly.

An auxiliary tool assembly for an agricultural implement is configured to support a finishing tool(s) at a location at or adjacent to the aft end of the implement. The auxiliary tool assembly includes a support arm extending lengthwise between a proximal end and a distal end, with the proximal end of the support arm being pivotally coupled to a portion of the implement at or adjacent to its aft end so that the tool assembly is pivotable relative to the implement between a work position and a transport position. In addition, the finishing tool(s) is configured to be coupled to or otherwise supported relative to the ground by the support arm at a location between its proximal and distal ends. Moreover, the auxiliary tool assembly includes one or more surface-engaging wheels coupled to the distal end of the support arm.

One or more techniques and/or systems are disclosed for proving operation of a vehicle towing an implement. A hitch assembly can be used to adjust or distribute a vertical downward force that an attached implement applies to the frame of a vehicle towing the implement. A sensor assembly can identify the torque that is being applied to the front and rear axles. The torque data can be used to generate adjustments to the vertical load actuator, which can to adjust an amount of load applied to the front and/or rear axles. In this way, vertical load may be efficiently distributed between the front and rear axles automatically.

A method for increasing the load on driving rear wheels (KB, KP) of a tractor during soil cultivation with a farm implement (2), attached to a three-point linkage (1) of the tractor. A vertical position of the attached implement (2, 20) is adjusted relative to the tractor by a position of the arms (4) of a lifting device and by adjustment of the length of the upper link (13) of the three-point linkage (1) of the tractor. After adjusting the length of the upper link (13), the axial force acting/induced in the upper link (13) is determined and during travel of the tractor is continuously monitored and automatically maintained at the adjusted value. Also the adjusted vertical position of the implement (2) attached to the tractor is continuously monitored (2) and is automatically maintained at the adjusted value, thereby maintaining the vertical position of the attached implement (3) in this regulation and thus also constant ploughing depth.

A device for influencing vertical dynamics of an agricultural vehicle includes a mass mounted on the agricultural vehicle, a positioning system for controlling movement of the mass in vertical direction, a sensor device configured to detect a surface profile of an upcoming vehicle path segment, and an electronic control unit adapted to calculate an expected disturbance input for the upcoming vehicle path segment based on the detected surface profile. The electronic control unit operably controls the positioning system to execute a compensation movement of the vehicle that reduces the expected disturbance input by means of the mass.

Systems, methods, and apparatus for shifting weight between a tractor and toolbar and between sections of the toolbar, for controlling operative height of a toolbar and sections of a toolbar and for folding a toolbar between a work position and a transport position. A ground engaging wheel and an actuator are coupled to the toolbar. In one embodiment, a fluid control system is responsive to a command signal to modify the actuator pressure such that the actuator pressure corresponds to a desired pressure.
