摘要： A row unit for a seeding machine includes a ground view sensor coupled to the frame. The ground view sensor is operable to sense the furrow and generate depth signals corresponding to actual sensed depth of the furrow. The row unit also includes a controller configured to receive the signals, and a downforce adjustment mechanism coupled to the frame and to the controller. The controller is configured to activate the downforce adjustment mechanism to adjust a downforce on the frame based on the signals received by the controller.

摘要： A seeding machine includes a main frame, and a row unit coupled to the main frame. The row unit has a row unit frame, a gauge wheel coupled to the row unit frame, and a furrow opener coupled to the row unit frame, the furrow opener having a stationary or rotating surface that contacts and moves soil. The row unit also includes a furrow closer, the furrow closer having a stationary or rotating surface that contacts and presses soil. The seeding machine also includes a downforce adjustment system for adjusting an amount of downforce applied to the row unit, the downforce adjustment system including a moisture sensor, a controller configured to receive a signal from the moisture sensor, and an actuator configured to change the amount of downforce applied to the row unit based on the signal received by the controller.

摘要： A variable is sensed that is indicative of a performance of a machine. A rate of change of the sensed variable is determined, and a control signal is generated for controlling an agricultural vehicle, based upon the rate of change in the value of the sensed variable.

摘要： A seed sensor senses seeds on a row unit and generates a seed sensor signal. A number of planting characteristics, such as a seed orientation, seed slugging, delivery system wear, and seed abnormalities, can be detected based on the seed sensor signal. The planter can be controlled based on the detected planting characteristics.
