A method for determining a mass of an implement includes providing a rear powerlift having at least one upper link and at least one lower link and a support structure disposed at the rear of a utility vehicle. The method includes defining an angle () between the upper link and a vehicle horizontal line, an angle () between the lower link and the vehicle horizontal line, an angle of inclination () of a vehicle horizontal line relative to a terrestrial horizontal line, a path (LV) representative of a connection along the lower link between the support structure and the implement, and a force (F.sub.U) impinging on a connection between the upper link and the implement and acting along the upper link. The mass is determined by at least one of the angle (), the angle (), the angle of inclination (), the path (LV), and the force (F.sub.U).

A method for making available a ballasting proposal for an agricultural tractor includes providing an implement for the tractor, calculating a target tractive power for the implement for each axle of the agricultural tractor, and deriving a target value for an axle load to be maintained on each axle based upon a function of the calculated target tractive power. The method further includes determining an actual axle load on each axle, comparing the target value to the actual axle load, calculating an axle ballasting value based on a result of the comparing step required to maintain the target valve, and outputting the ballasting value.

The present disclosure refers to a method for controlling operation of an agricultural system, comprising a tractor; an implement (100) hitched through a draw bar (10) to the tractor, the implement (100) having working tools (31) configured to engage with a ground and/or an agricultural product in operation while the tractor is drawing the implement (100) over a field; and a control system, comprising a control unit (2) and a sensor arrangement (1) connected to the control unit (2) through a control bus (5), wherein the control unit (2) is configured to determine a draft force applied to the implement (100) through the draw bar from measurement signals detected by the sensor arrangement (1); the method comprising operating the implement in either normal mode or field transport mode of operation based on different draft force thresholds.

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.

An implement load management method includes sensing respective loads on at least one wheel supporting a central portion and one or more wheels supporting a wing portion, the central portion and the wing portion comprising segments of an implement; and actuating a fluid-type cylinder to cause pivotal movement between the central portion and the wing portion based on the sensed loads, wherein the actuating comprises causing fluid flow in either of two opposing directions through the fluid-type cylinder based on evaluation of a load on the one or more wheels supporting the central portion and the one or more wheels supporting the wing portion. Related implement load management systems are also disclosed.

In one embodiment, an implement load balancing method comprising sensing respective loads on one or more wheels supporting a central portion and one or more wheels supporting a wing portion, the central portion and the wing portion comprising segments of an implement; and causing, via actuation of a fluid-type cylinder, pivotal movement between the central portion and the wing portion based on the sensed loads, wherein the causing comprises causing fluid flow in one direction through the fluid-type cylinder based on a load on the one or more wheels supporting the central portion being greater than a load on the one or more wheels supporting the wing portion and causing fluid flow in an opposing direction through the fluid-type cylinder based on a load on the one or more wheels supporting the central portion being less than a load on the one or more wheels supporting the wing portion.

Unique self-propelled soil working machines are disclosed. In certain exemplary embodiments the self propelled soil working machine includes a tool carrier which is actively adjustable to provide variable downward force on a soil working tool via a suspension element which is further passively responsive to accommodate motion of the tool in response to external force. In certain exemplary embodiments, the tool carrier is configured to adjust the working depth and pitch of the tool. Further embodiments, forms, objects, features, advantages, aspects, and benefits shall become apparent from the following description and figures.

An agricultural implement configured to shift weight between a center toolbar and left and right wing sections. Each wing section includes inner and outer sections pivotally coupled about a horizontal axis. Left and right wing flex actuators pivot the outer wing sections with respect to the inner wing sections about the respective left and right horizontal axes. Each of the inner wing sections is pivotally coupled to the center toolbar about respective left and right vertical axis. The center toolbar section is supported by a center wheel assembly and distal ends of the left and right outer wing sections are supported by respective left and right wing wheel assemblies. A monitor is in signal communication with load sensors on each of the wheel assemblies and a fluid control system to actuate the wing flex actuators so the measured center wheel load approaches a center wheel target load.
