Abstract: A method for calibrating a height control system for an implement of an agricultural work vehicle can include providing an input signal to the height control system to adjust a height of the implement relative to the ground surface; monitoring the height of the implement relative to the ground surface; adjusting at least one gain of the height control system; and determining a maximum stability gain of the height control system based on the at least one gain and the monitored height. The maximum stability gain can correspond with a stability point of the height control system at which the height control system transitions from stable to unstable. The method can include setting gain(s) of the height control system based on the maximum stability gain.

Abstract: A combine harvester includes (i) a grain tank for storing separated grain and having a bottom end and a top end, and (ii) a grain tank level sensor array for detecting a level of grain in the grain tank. The grain tank level sensor array includes a plurality of sensors, wherein the grain tank level sensor array extends between the bottom end and the top end of the grain tank. The sensors are spaced apart between the bottom end and the top end. A spacing between adjacent sensors decreases in a direction towards the top end of the grain tank.

Abstract: A system for controlling harvesting implement operation of an agricultural harvester includes a fluid-driven actuator configured to adjust a position of a harvesting implement of the agricultural harvester relative to a feeder housing of the agricultural harvester. Additionally, the system includes a sensor provided in operative association with the fluid-driven actuator, with the sensor configured to capture data indicative of a parameter associated with a force acting on the fluid-driven actuator. Furthermore, the system includes a computing system configured to monitor the parameter relative to a predetermined minimum parameter value. Moreover, when the monitored parameter falls below the predetermined minimum parameter value, the computing system is configured to determine that the harvesting implement has contacted a field surface of a field across which the agricultural harvester is traveling.

Abstract: An agricultural harvester includes a frame, a feeder coupled to the frame, and a harvesting implement coupled to the feeder. Additionally, the agricultural harvester includes an actuator configured to rotate the harvesting implement relative to the frame between a non-turned position and a turned position. Moreover, the agricultural harvester includes a sensor configured to capture data indicative of a turn being made by the agricultural harvester and a computing system communicatively coupled to the sensor. In this respect, the computing system is configured to determine a magnitude of the turn based on the data captured by the sensor. In addition, the computing system is configured to compare the determined magnitude of the turn to a minimum threshold value and, when the determined magnitude exceeds the minimum threshold value, control the operation of the actuator such that the harvesting implement is rotated to the turned position.

Moreover, the agricultural harvester includes a second actuator including an extendible rod, with the second actuator coupled between the one of the frame and the feeder or the feeder and the harvesting implement such that an oblique angle is defined between the first and second actuators. In this respect, the rods of the first and second actuators are configured to be extended differing amounts such that harvesting implement is moved relative to the frame along two degrees of freedom.

In addition, the method includes determining at least one control output for controlling an operation of a height cylinder and a tilt cylinder provided in operative association with the harvesting implement based on the established correlation, and controlling the operation of the height cylinder and/or the tilt cylinder based on the control output(s) to adjust the vertical positioning and/or the lateral tilt of the harvesting implement relative to the ground surface.

Abstract: In one aspect, a method is disclosed for automatically controlling a height of an implement of an agricultural work vehicle relative to a ground surface. The method may include monitoring the height of the implement and a vehicle speed; determining an implement height error by comparing the height of the implement with a predetermined target height; and calculating a sensitivity factor based on a sensitivity setting. When the monitored vehicle speed is greater than a predetermined speed threshold, the sensitivity factor may equal a first constant sensitivity value that is proportional to the sensitivity setting. The method may include reducing the sensitivity factor to less than the first constant sensitivity value when the monitored vehicle speed becomes less than the predetermined speed threshold and adjusting the height of the implement relative to the ground surface based on the implement height error and the sensitivity factor.
