An automated implement control system includes one or more distance sensors configured for coupling with an agricultural implement. The one or more distance sensors are configured to measure a ground distance and a canopy distance from the one or more sensors to the ground and crop canopy, respectively. An implement control module is in communication with the one or more distance sensors. The implement control module controls movement of the agricultural implement. The implement control module includes a confidence module configured to determine a ground confidence value based on the measured ground distance and a canopy confidence value based on the measured canopy distance. A target selection module of the implement control module is configured to select one of the measured ground or canopy distances as a control basis for controlling movement of the agricultural implement based on the comparison of confidence values.

A towable agricultural implement, having a center frame and two wing frames pivotally coupled on the center frame to move between a field frame position extending laterally outward and a range of transport positions extending generally rearward, further includes a transport wheel on each wing frame that is pivotal about an upright steering axis through a range of wheel positions including a neutral transport wheel position for rolling forwardly. Each transport wheel is pivotal from the neutral transport wheel position in either one of two opposing steering directions under control of a steering actuator through an overall range of greater than 90 degrees. The wheels can be steered in a common direction during transport. A control system can also attempt to maintain a constant angle between the center section and the wings to allow reversing while in transport mode.

System that automates crop maintenance activities, such as cultivating and weeding, with a device that intelligently and independently controls two blades that drag along either side of a crop row using sensors to repeatedly track the position of the blades and of the plants in the row. Blades may be moved in and out independently using an actuator for each blade to contour closely around the individual plants, even if plants or rows vary in their positions, and even if plant sizes and shapes differ. An illustrative system may use a single camera and a processor per crop row; the processor may analyze camera images to locate plant positions and shapes, to plan blade trajectories, and to control blade actuators. The processor may be able to control blade movement precisely to respond quickly to sensor input on changes in plant positions, shapes, and sizes along the row.

A trench detection system for an agricultural implement includes a row unit configured to form a trench in soil, to deposit an agricultural product in the trench, and to at least partially close the trench after deposition of the agricultural product. The trench detection system also includes a tactile probe assembly behind the row unit that, in operation, contacts the soil after closure of the trench and generates a signal indicative of a quality of the closure.

A plough comprising: a plough body; an actuator mechanism that is configured to adjust a pitch angle of the plough body; and a controller. The controller is configured to: determine an actuator-control-signal for setting the pitch angle of the plough body based on control-data; and provide the actuator-control-signal to the actuator mechanism.
