One or more techniques and/or systems are disclosed for adjusting the downward vertical force applied to the vehicle frame. In this way, an operator can adjust or distribute a vertical downward force that an attached implement applies to the frame of a vehicle towing the implement. A front end of a vertical load member can be pivotably coupled to the vehicle frame at a point in front of the rear axle of the vehicle, and a rear end of the vertical load member can be coupled to a hitch attachment assembly, coupled with a towed implement, at a rear end of the vertical load member. An actuator can be pivotably coupled with the vertical load member rearward of the vehicle axle, and to the vehicle frame. The vertical load member can be raised and lowered using the actuator, which raises and lowers the hitch assembly at the rear, and pivots the vertical load member at the front.

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 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.

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 a crop harvesting machine there is provided a pair of hydraulic float cylinders or springs for a header such as a rotary mower relative to a self-propelled vehicle, where a float spring force is controlled to provide a predetermined lifting force is provided to the header. The spring force is varied in response to detection of ground speed to decrease the lifting force at higher ground speeds. A position sensor is used to generate an indication of movement and/or acceleration. The electronic control is arranged, in response to changes in the sensor signal, to temporarily change the control signal to vary the lifting force and thus change the dynamic response of the hydraulic float cylinder. In order to reduce static friction so that the system can react quickly, an arrangement is provided for causing relative reciprocating movement in an alternating wave pattern between the piston and cylinder.

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.

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.
