Abstract: A mobile machine includes a frame, and a set of wheels supporting the frame. The mobile machine also includes a set of ground-engaging tools mounted to the frame that are movable relative to the wheels to change a depth of engagement of the ground engaging-tools with ground over which the mobile machine travels. A first sensor senses a position of the frame relative to the ground surface over which the mobile machine is traveling. A second sensor senses a position of the frame relative to the wheels. The sensor signals from both sensors are used to control the frame height.

Abstract: An agricultural implement includes a plurality of ground-engaging tools configured to modify a surface configuration of an agricultural field and a hydraulically-controlled subsystem configured to modify an operating angle of the plurality of ground-engaging tools.

Abstract: A method of controlling tilt of an agricultural implement being towed by a tow vehicle along a field includes providing a controller, a first sensor, a second sensor, and an actuator coupled to the implement. The method includes detecting a baseline level of the tow vehicle with the first sensor at a first location in the field, wherein the implement is located at a second location in the field spaced rearward of the first location. The controller determines when the implement will be at the first location in the field, and an implement level of the implement is measured with the second sensor once the implement is at the first location. The implement level is compared to the baseline level with the controller. The controller determines if the difference between the implement level and baseline level is within a tolerance range, and further controls the actuator as needed.

The mobile machine also includes a set of ground-engaging tools mounted to the frame that are movable relative to the wheels to change a depth of engagement of the ground engaging-tools with ground over which the mobile machine travels. A sensor senses the ground surface over which the mobile machine is traveling. The sensor can do this by sensing the position of a ground-following device having a proximal end coupled to the frame and a distal end configured to engage a surface of the ground and follow the surface of the ground as the mobile machine moves in a direction of travel, or by sensing the surface of the ground behind a surface cleaning device that exposes the surface of the ground to the sensor.

Abstract: An agricultural machine includes a set of ground engaging elements that perform a ground engaging operation. The agricultural machine includes a rearward sensor mounted to the agricultural machine to sense an area of ground behind the agricultural machine and generate a rearward sensor signal. The agricultural machine includes rearward zone generator logic that determines a first zone and a second zone, wherein the first zone and the second zone represent portions of the area of ground behind the agricultural machine. The agricultural machine includes rearward residue generator logic configured to receive the rearward sensor signal and determine a first residue metric indicative of the amount of residue in the first zone. The agricultural machine includes control logic that controls one or more aspects of the ground engaging operation on the area of ground based on the first residue metric.

Abstract: One or more sensors identify a characteristic of a towed implement using non-visual electromagnetic radiation, auditory detection or temperature detection. The characteristic of the implement is compared to a reference characteristic to determine whether the implement has a problem. If so, control signals are generated to control a controllable subsystem based upon the identified problem.

Abstract: A residue detection and implement control system and method are disclosed for an agricultural implement. The system includes a source of environment data and image data of an imaged area of a crop field containing residue. The system includes a data store containing a plurality of image processing methods and at least one controller that processes the image data according to one or more image processing instruction sets. The controller selects one or more of the image processing methods based on the environment data, and processes the image data using the selected image processing instruction(s) to determine a value corresponding to residue coverage in the imaged area of the field. The controller adjusts the configuration of the agricultural implement to respond to the amount and type of residue detected.
