Abstract: Various methods, systems, and devices for flexible and accurate seed spacing control in a seed planting system. The various embodiments receive singulated seed from a metering device and control movement of the seed toward a seed spacing device that receives the seed. The seed spacing device, which is disposed near the soil surface, independently controls the ejection of the seed from the device and thus the spacing of the seed in the furrow.

Abstract: Disclosed herein is a system for monitoring rocks in a field. The system includes at least one row unit having an opening disk, a gauge wheel, and a gauge wheel load sensor. The system further includes a processor and a storage media. In various implementations, the system evaluates gauge wheel load sensor data, vertical acceleration data, and/or down force bore pressure data to detect when a row unit strikes a rock. In some implementations, the system can detect the size of the rock, the location of the rock within the soil, and the severity of a rock strike.

Abstract: The disclosure relates to agricultural systems. The systems have stalk sensor assemblies and/or data visualization systems. The stalk sensor assemblies are configured for assessing the size and other characteristics about crops, such as corn and other grains entering an agricultural implement, such as a harvester. The stalk sensor assemblies may use an estimation of the stalk perimeter to establish stalk size and therefore further features about the crop. The visualization system utilizes data from the stalk sensor assemblies to calculate and display relevant information about the crop.

Abstract: The disclosed apparatus, systems and methods relate to a steerable toolbar. The toolbar is able to rotate relative to the tractor or other driving vehicle to reduce misalignment and/or cross-track error. Actuators can be utilized with draft links to pivot the toolbar around a central pivot point and improve the following path of the toolbar implement.

Abstract: The present invention relates to a practical approach to alleviate or remove the jerky heading change in ArVs. The rate of change of articulation angle in heading kinematics is effectively canceled. This modification (also called as transformer) can be done such that articulated vehicles can change their heading similar to front wheel-steered vehicles.

Abstract: The disclosed apparatus, systems and methods relate to devices, systems and methods for the selective application of down pressure or downforce to a row unit. Each row unit has a dual-action actuator which is in fluidic communication with the hydraulic system for independent control of the supplemental downforce. The pressure line can be directly routed to the lift chamber for a constant supply of up pressure, with down pressure selectively applied to the down chamber for accurate control of the supplemental downforce system.

Abstract: The disclosed apparatus, systems and methods relate to determining cross track error between a stored planted location and the actual physical location of plants. An array of active light sensors is mounted on a vehicle for travel above the plants. The array of active light sensors generate an electrical signal from each sensor corresponding to the reflected light from the sensor. A computer system generates a reflectance curve from the array of sensors to determine the location of a plant below the array of sensors and also generates the cross track error.
