  • Sensing and control of liquid application using an agricultural machine
    Patent number: 11944046
    Abstract: An agricultural machine applies liquid material to a field. Valve control signals control valves to apply the liquid material. Row pressure on the agricultural machine is sensed to identify when the valve is opened to apply the liquid material. The valve control signals are generated, based on the row pressure, to control the valves to apply the liquid material at a desired location in the field, relative to plant locations in the field.
    Type: Grant
    Filed: August 3, 2018
    Date of Patent: April 2, 2024
    Assignee: Deere & Company
    Inventors: Grant J. Wonderlich, Kenneth Herrmann, Michael C. Steele, Kilian Wolff, Gerrit Pruessmann
  • Using an accumulator to improve delivery of liquid through a valve on an agricultural machine
    Patent number: 11154891
    Abstract: An accumulator is added in-line with a valve on an agricultural machine and downstream of the valve. The valve is controlled to apply liquid material to a field over which the machine is traveling.

  • Sensing flow and control of liquid application using an agricultural machine with row pressure sensors
    Patent number: 10827740
    Abstract: An agricultural machine applies liquid material to a field. Valve control signals control valves to apply the liquid material. Row pressure on the agricultural machine is sensed to identify when the valve is opened to apply the liquid material. A flow meter senses a flow of liquid applied to the field. The valve control signals are generated, based on the row pressure, and the sensed flow.

  • Using a small diameter exit hose to improve delivery of liquid through a valve on a nutrient or chemical application system of an agricultural machine
    Patent number: 10701857
    Abstract: A mobile agricultural machine has a valve controlled to apply liquid material to a field. An application assembly defines a conduit from the valve to a distal application tip. The application assembly includes a distal conduit section that has an inner diameter that is smaller than an inner diameter of a more proximal conduit section, that is closer to the valve, than the distal tip of the application assembly.
