Theory of Operation

John Deere Rate Controller 2000 controls product application components on many configurations. It controls rate and implement sections using coverage maps, boundaries, and global positioning system (GPS) information. John Deere Rate Controller 2000 can control up to five liquid and (or) dry products all while utilizing John Deere Section Control.

John Deere Rate Controller 2000 can control multiple product configurations at once. It can control multiple products and the corresponding sections independently or group them together. For example, a five section anhydrous applicator that simultaneously applies a dry product can be configured and controlled with two section groups.

John Deere Rate Controller 2000 configurations receive inputs from the system components to assign drivers that perform functions. The two main functions are rate control and section control.

Rate Control

• Inputs
  • Rate Sensor (flowmeter that measures volume over time or encoder that measures revolutions)
  • Pressure Sensor (optional)
  • Ground Speed
  • Implement Width

• Drivers
  • Control Valve Signals—If control unit senses rate is too high, system attempts to close the control valve. If rate is too low, system attempts to open the control valve to increase flow.

Section Control

• Inputs
  • GPS Location
  • Section Control Settings—Settings determine amount of time the control unit sends on or off commands to a valve.

• Drivers
  • Section Valve Signals—Pins within the control unit are assigned to drivers that control sections. If a section is commanded open, control unit sends the required signal to the specific valve.

John Deere Rate Controller 2000 is capable of many other functions depending on configuration. Tank fill monitoring, tank level monitoring, fan speed control, spinner speed control, and bin chaining are some of these features.
