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.

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 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.

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.

An agricultural implement includes at least one row unit having a plurality of support members, each of which is pivotably coupled to an attachment frame or another of the support members to permit vertical pivoting vertical movement of the support members, and a plurality of soil-engaging tools, each of which is coupled to at least one of the support members. A plurality of hydraulic cylinders are coupled to the support members for urging the support members downwardly toward the soil. A plurality of controllable pressure control valves are coupled to the hydraulic cylinders for controlling the pressure of hydraulic fluid supplied to the cylinders. A plurality of sensors produce electrical signals corresponding to predetermined conditions, and a controller is coupled to the sensor and the controllable pressure control valves. The controller receives the electrical signals from the sensors and produces control signals for controlling the pressure control valves.

A cultivator includes at least one cultivator row unit, each of the at least one cultivator row unit having a support assembly for securing the cultivator row unit to a tool bar, a shank, an earth working tool operatively connected to the shank, and at least one assembly for providing discrete incremental adjustment for at least one of (a) an angle of the earth working tool, (b) a depth of the earth working tool, and (c) a gauge wheel depth.

A header is supported by a pair of hydraulic float cylinders, where a float pressure to the cylinders is directly controlled by an electronic control supplying a variable control signal to a PPRR valve arrangement to maintain the float pressure at a predetermined value. At the set pressure a predetermined lifting force is provided to the header. A position sensor is used to generate an indication of movement and/or acceleration and/or velocity. 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. A lift force greater than that required to lift the header can be provided by a lift cylinder and can be opposed in a controlled manner to apply a controlled downforce by the back of the same cylinder or by a separate component.

The present disclosure relates to a method for adjusting a working depth of a plough implement, the plough implement comprising a plurality of ground engaging tools for penetrating and moving soil and a depth adjustment apparatus configured to adjust a working depth of at least one of the ground engaging tools, wherein the method comprises receiving control-data indicative of at least one of an operation the plough implement or a field condition of a field across which the plough implement is moved; and automatically controlling an operation of the depth adjustment apparatus in a manner that adjusts a working depth of the at least one ground engaging tool on the basis of the control-data received.
