Abstract: According to an aspect of the invention, the brake pedal of an agricultural vehicle can be used as an interface to control auto fold/unfold sequences on a sprayer. This can allow functionality to be moved from a button, such as on the armrest, to the brake pedal using a controller, sensing and software. In one aspect, a button on the armrest can start the sequence, as long as the brake pedal is depressed. After the button is pressed, the operator can remove his hand from the button, but maintain the brake pedal depressed. If the operator lifts his foot off of the pedal, or initiates a different boom control button press, the sequence can stop. This can advantageously allow the operator to have the use of his hands during the sequence.
