Abstract
An agricultural sprayer includes a purge tank and first and second nozzles. Furthermore, the system includes a first valve fluidly configured to selectively permit air to flow to the first nozzle and a second valve fluidly configured to selectively permit the air to flow to the second nozzle. A computing system is configured to receive an input indicative of initiation of a purging operation and, upon receipt of the input, control an operation of a main valve to allow the air to flow through a main fluid conduit. Furthermore, the computing system is configured to monitor the air pressure associated with the purge tank and control the operation of the first and second valves during the purging operation based on the monitored air pressure.
