Abstract: 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.

Abstract: A finishing tool control system for an agricultural implement may include a controller communicatively coupled to a first and a second sensor. The controller is configured to control a height of a finishing tool above a soil surface. Further, the first sensor is configured to output a signal indicative of a height of a main frame of the agricultural implement above the soil surface. In response to determining that a height increase of the main frame exceeds a threshold height adjustment, the controller increases the height of the finishing tool. The second sensor is configured to output a signal indicative of the height of the finishing tool of the finishing assembly above the soil surface. Moreover, in response to determining that a height of the finishing assembly above the soil surface is less than a threshold value, the controller increases the height of the finishing tool.

Abstract: An agricultural system having at least two connectors for moving a first tool with a first marker and a method are configured to check a controllability of the tool by connecting a first actuator with at least one of the least two connectors for moving the first tool in a first degree of freedom, triggering an actuation via one connector, receiving sensor information from a sensor unit capturing a first marker connected with the first tool and determining whether the first marker moves in the first degree of freedom in response to the triggered actuation via the one connector.

Abstract: 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.

Abstract: A 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. The tool carrier is configured to adjust the working depth and pitch of the tool.

Abstract: A method for adjusting the position of a power lift of an agricultural utility vehicle includes storing one or more target positions in a control device, moving the control member rotationally relative to and translationally along a longitudinal axis, and adjusting the one or more target positions of the power lift within a position range defined by a lower limit position and an upper limit position by a variable movement of the control member.

Abstract: A disc blade angle control system for an agricultural implement includes a controller having a memory and a processor. The controller is configured to receive a signal indicative of a side load applied to a disc blade of the agricultural implement. The disc blade is configured to engage soil, and the side load corresponds to a force applied to the disc blade along an axis parallel to a rotational axis of the disc blade. The controller is also configured to control an actuator to adjust an angle of the disc blade based on the side load.

Abstract: An agricultural implement includes a frame and a ground-engaging tool supported on the frame, with the ground-engaging tool configured to perform an operation on a field as the agricultural implement travels across the field. The agricultural implement includes an imaging device configured to generate image data depicting a portion of the field and a computing system communicatively coupled to the imaging device. In this respect, the computing system is configured to identify a plurality of residue pieces present within the portion of the field based on the image data generated by the imaging device. Furthermore, the computing system is configured to determine a residue length parameter associated with the identified plurality of residue pieces. Additionally, the computing system is configured to control a travel direction of the agricultural implement based on the determined residue length parameter.

Abstract: A work vehicle includes a chassis, and a work implement movably coupled to the chassis, the work implement configured to perform a field-engaging function. The work vehicle also includes an actuator coupled to the work implement and configured to adjust a position of the work implement relative to a ground surface, and a controller in communication with a communication module. The controller is configured to monitor a location of the work machine via the communication module, and load a field map that identifies spatial information about a corresponding field, and a characteristic of the actuator associated with the spatial information. The controller is further configured to partition the spatial information into at least one pass traversable by the work machine. The controller is also configured to create an adjustment event to adjust the actuator in response to the location of the work machine moving within the at least one pass.
