Claim 8:
9. A method for purging nozzles of an agricultural sprayer, the agricultural sprayer including a pressurized air source, a main valve configured to selectively permit air from the pressurized air source to flow through a main fluid conduit, and first and second nozzles configured to dispense an agricultural fluid onto an underlying field, the agricultural sprayer further including a first valve configured to selectively permit the air from the main fluid conduit to flow to first nozzle and a second valve configured to selectively permit the air from the main fluid conduit to flow to the second nozzle, the method comprising:
receiving, with a computing system, an input indicative of initiation of a purging operation to purge the agricultural fluid present within the first and second nozzles;
upon receipt of the input, controlling, with the computing system, an operation of the main valve such that the main valve is moved to an opened position to allow the air to flow through the main fluid conduit;
receiving, with the computing system, pressure sensor data indicative of an air pressure associated with the pressurized air source via a communicative link;
monitoring, with the computing system, the air pressure associated with the pressurized air source based on the received pressure sensor data; and
transmitting, with the computing system, control signals to the first and second valves to control an operation of the first and second valves during the purging operation based on the monitored air pressure.
