A method and system for determining working heights independent of the type of coupling of a plurality of agricultural attachments using a sensor assembly is disclosed. The sensor assembly includes at least one sensor for recording measured data and a control assembly. The attachments may be coupled to an agricultural production machine by an equipment interface using different types of coupling. The attachments are temporarily coupled to the agricultural production machine using the different types of coupling. The control assembly determines the working heights independent of the type of coupling of the differently coupled attachments when in a coupled state by using the same sensor. The control assembly displays the working heights determined independent of the type of coupling by means of the agricultural production machine, and/or uses them to control and/or regulate the agricultural production machine.

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.
