A method and system for planning an optimized soil cultivation process of a field for anf agricultural combination is disclosed. The agricultural combination includes an agricultural production machine and a soil cultivating agricultural attachment. A planning control assembly is used to determine recommended actions for the soil cultivation process with an expert model using soil data of the field, wherein the soil data of the field is location-dependent.

A method and system for measuring a working height, such as an absolute working height, of a plurality of agricultural attachments using a sensor assembly is disclosed. The sensor assembly includes a sensor and at least one sensor holder. The sensor holder is mounted at mounting positions onto different attachments, with the sensor being reversibly mounted in the sensor holder at the mounting position. The sensor, in a mounted state, records measured data relating to a working height of the agricultural attachment and transmits the measured data to the control assembly. In turn, the control assembly determines the working height of the particular attachment from a calibration data set specific to the mounting position.

A system and method for controlling, such as pre-optimizing, agricultural work processes for agricultural combinations is disclosed. Agricultural combinations include an agricultural production machine and different agricultural attachments. A sensor assembly determines an absolute working height of the agricultural attachments using a sensor measuring data regarding the absolute working height. The agricultural combination includes a combination control assembly that controls and/or regulates machine parameters of the particular agricultural combination based on an optimization data set and the measured data obtained during the working process. An optimization control assembly determines the optimization data set from competing optimization goals, optimization data both apart from and relating to the combination. The sensor assembly determines the absolute working height of the different agricultural attachments using the same sensor, and the optimization data set suggests the optimized working height of the agricultural attachment and/or suggestions for optimized settings of other machine parameters of the agricultural combination.

A method and system for regulating a rear power lift of an agricultural production machine in an agricultural combination is disclosed. The agricultural combination includes an agricultural production machine and an agricultural attachment. The agricultural attachment is connected to the agricultural production machine via a rear power lift of the agricultural production machine. The agricultural production machine includes a driver assistance system that regulates machine parameters of the rear power lift using position regulation and/or traction regulation on which a slip control is superimposed. The driver assistance system determines a target slip for slip regulation optimized for position regulation and/or traction regulation depending on at least one existing soil property and at least one existing tire property, and regulates the rear power lift to the optimized target slip.

A method and system for collecting agricultural measured data in an agricultural production machine that is combined with at least one agricultural attachment for fieldwork is disclosed. A sensor assembly is provided that has a sensor and a control assembly. The sensor may be integrated in combinations comprising (or consisting of) an agricultural production machine and a plurality of agricultural attachments. The sensor records measured data relating to at least one work quality parameter of the particular attachment and transmits it to the control assembly. In turn, the control assembly generates a common data set in a standardization routine from the measured data relating to the different attachments.

Systems and methods provide automatic assignment of control of a plurality of hydraulic circuits of an associated work vehicle to a plurality of operation systems of an implement. A hydraulic circuit assignment control unit includes a processor, a memory device, logic stored in the memory device, and a communication circuit operatively coupled with the processor. The processor executes the logic to associate an activation of a first hydraulic circuit of the plurality of hydraulic circuits of the associated work vehicle with a physical exercise of an operation system of the plurality of operation systems of the associated implement, and generates pairing assignment data representative of the association of the activated first hydraulic circuit with the physical exercise of the operation system of the implement. The logic generates directionality confirmation and calibration data that is communicated to the plurality of operation systems with the pairing assignment data.

An agricultural row unit for use with a towing frame hitched to a tractor includes an attachment frame adapted to be rigidly connected to the towing frame, a linkage pivotably coupled to the attachment frame, and a row unit frame having a leading end pivotably coupled to the linkage to permit vertical pivoting movement of the row unit frame relative to the attachment frame. A hydraulic cylinder coupled to the attachment frame and the linkage, for urging the row unit frame downwardly toward the soil, includes a movable ram extending into the cylinder, and a hydraulic-fluid cavity within the cylinder for receiving pressurized hydraulic fluid for advancing the ram in a direction that pivots the linkage and the row unit frame downwardly toward the soil. An accumulator positioned adjacent to the hydraulic cylinder has a fluid chamber containing a diaphragm, with the portion of the chamber on one side of the diaphragm being connected to the hydraulic-fluid cavity in the hydraulic cylinder, and the portion of the chamber on the other side of the diaphragm containing a pressurized gas.
