Abstract: An agricultural sprayer has a fluid delivery network that supplies one or more sets of spaced-apart nozzles for the application of plant protection products. An electronic controller is arranged to receive and store an operating parameter for each one of a plurality of drift reduction classes. The operating parameter may be an upper pressure limit. The controller is operable to control at least one of a pump, a vehicle speed, a nozzle selection, and a display based on the operating parameter of a selected one of the plurality of drift reduction classes.

Abstract: A controller for an agricultural sprayer machine is configured to receive for each of a plurality of nozzle sets a respective upper pressure limit, a nozzle reference flow, and a nozzle reference pressure. For each one of the plurality of nozzle sets, a speed setpoint is calculated based upon the application rate setpoint, the nozzle reference flow, the nozzle reference pressure, and the product pressure setpoint.

Abstract: A method of automatically selecting a nozzle set from a plurality of nozzle sets on an agricultural spraying machine is provided. The method includes receiving an application rate setpoint, and for each nozzle set an upper pressure limit, a lower pressure limit, a nozzle reference flow, and a nozzle reference pressure. A speed range is calculated for each nozzle set, wherein each speed range comprises a lower speed limit and an upper speed limit. One of the nozzle sets is selected based upon a sensed forward speed and the calculated speed ranges.
