Title: Foldable boom for an agricultural sprayer

Abstract: The present disclosure relates to a folding boom for an agricultural sprayer. The boom includes a first piece pivotally connected to a second piece. The folding boom also includes a hydraulic cylinder for hydraulically pivoting the first boom piece relative to the second boom piece between a folded orientation and an extended orientation. The hydraulic cylinder includes a cylinder portion in which a piston structure is mounted. The cylinder portion and the piston structure are configured to slide axially relative to one another when the first boom piece is pivoted relative to the second boom piece. The folding boom further includes an accumulator in fluid communication with the cylinder portion for accumulating hydraulic fluid when the first boom piece collides with an obstruction and is pivoted from the extended orientation toward the folded orientation.
