  • Patent number: 12144281
    Abstract: An agricultural product application system such as an air seeder or a sprayer includes a controller, a product source, and a plurality of product dispensing sections. Each of the dispensing sections include a metering module and a product sensor arranged to detect product passing through one or more product dispensing devices. The controller determines a dispense activation delay (don) for each product dispensing section by measuring a delay between activation of the metering module and the product sensor detecting product arriving. The delay is optionally used for automatic control of the product dispensing sections and/or for logging georeferenced application data.

  • Patent number: 11576300
    Abstract: An agricultural product application system includes a controller and product dispensing apparatus. The product dispensing apparatus includes a metering module in communication with the controller and is configured to control a flow rate of product from a product source to product dispensing units. A display device is in communication with the controller. The controller receives operating limits and an application rate of the product dispensing apparatus. The controller determines a forward speed range based upon the operating limits and on the application rate. Display information is generated for providing a visual representation on the display device of the forward speed range.
