An agricultural work system and a method for operating an agricultural work system are disclosed. The agricultural work system performs an agricultural work process and includes an agricultural production machine having at least two axles with at least one device interface and an attachment, which is connected via the device interface to the agricultural production machine. An axle load on at least one axle is determined using a sensor assembly, with the axle loads occurring or happening on axles of the agricultural production machine. An axle load ratio based thereon is cyclically determined using the computer unit of the driver assistance system of the agricultural production machine, coupled in time to the execution of the work process, with the driver assistance system taking into account the agricultural production machine and attachment configuration and operating parameters.

An agricultural work system and a method for operating an agricultural work system is disclosed. The agricultural work system comprises an agricultural production machine having two axles, a power lifter, and a driver assistance system, and an attachment connected to the agricultural production machine using the power lifter. The driver assistance system optimizes operation of the agricultural production machine by determining an axle load on at least one of the axles. Further, actual data records coupled in time to the execution of an agricultural work process are cyclically determined by the driver assistance system to automatically adjust the power lifter. In particular, an axle load ratio currently at the axles is determined as an actual data record and, using at least one additional actual data record to be determined, the driver assistance system automatically generates instructions to actuate the power lifter while simultaneously accounting for mutually influencing optimization target variables.

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.

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.

In one embodiment, an agricultural system includes a tool bar configured to couple to a tow vehicle. The tool bar is configured to support at least one row unit assembly. The agricultural system also includes a lift assist assembly coupled to the tool bar such that rotation of the tool bar relative to the lift assist assembly about a vertical axis is blocked. The lift assist assembly is configured to provide lifting support to the tool bar. The lift assist assembly comprises a frame, one or more rolling elements configured to contact a surface of a field, and one or more telescoping members configured to adjust a configuration of the lift assist assembly along at least one of a lateral axis, a longitudinal axis, and the vertical axis.

A towed soil cultivation implement (1) is proposed in which the soil tillage tools (5) are guided by a contact pressure controlled depth guide device (9), which enables a constant weight load on a downstream, adjustable reconsolidation implement (6) on uneven ground as well. In the process, the pull line between tractor (3) and soil cultivation implement (1) are maintained in an optimum position.

An agricultural implement includes a main frame. The agricultural implement also includes at least one disc gang including a plurality of disc blades, wherein the at least one disc gang is coupled to the main frame. The agricultural implement further includes a hitch system coupled to the main frame, wherein the hitch system is configured to couple the agricultural implement to a work vehicle and to transfer weight between the work vehicle and the agricultural implement to adjust a downward force applied on each disc blade of the plurality of disc blades in engaging soil.

The invention relates to a method for increasing the load on driving rear wheels (KB, KP) of a tractor during soil cultivation with a farm implement (2), in particular with a plough (20), attached to a three-point linkage (1) of the tractor, in which the vertical position of the attached implement (2, 20) is adjusted relative to the tractor by means of the position of the arms (4) of a lifting device and the length of the upper link (13) of the three-point linkage (1) of the tractor is adjusted. After adjusting the length of the upper link (13) of the three-point linkage of the tractor the axial force acting/induced in the upper link (13) is determined and during travel of the tractor continuously monitored and automatically maintained at the adjusted value, whereby also the adjusted vertical position of the implement (2) attached to the tractor is continuously monitored (2) and is also 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.

In addition, the invention relates to a device for performing the above-mentioned method for increasing the load on driving rear wheels of tractors during soil cultivation.
