System and method for controlling an air-assisted conveying system of an agricultural harvester

A method, comprising:

• receiving, via a controller comprising a memory and a processor, a first sensor signal indicative of a first air pressure at a first location within a line of an air-assisted conveying system of an agricultural harvester;
• receiving, via the controller, a second sensor signal indicative of a second air pressure at a second location within the line of the air-assisted conveying system;
• determining, via the controller, an air pressure differential based on the first air pressure and the second air pressure;
• in response to determining that the air pressure differential is greater than a threshold value:
• controlling, via the controller, a supplemental air source that provides supplemental air to the line for a supplemental air duration;
• and
• in response to the determining that the air pressure differential is greater than the threshold value during the supplemental air duration, controlling, via the controller, an operational air source that iteratively increases an operational air flow through the line during a plurality of iterations;
• wherein the plurality of iterations comprises an initial iteration and one or more successive iterations, and
• wherein an operational air flow of each of the one or more successive iterations is greater than an operational air flow of a preceding iteration of the plurality of iterations.
