Abstract
A sprayer system is provided for a work machine that includes a boom, a fluid source, and an air source. The sprayer system includes a spray device configured to selectively apply a fluid from the fluid source to an agricultural crop. A retractable arm includes a first arm segment, a second arm segment, a first hinge joint positioned such that the first arm segment is selectively foldable relative to the boom, and a second hinge joint positioned such that the second arm segment is selectively foldable relative to the first arm segment. An actuation assembly coupled to the retractable arm selectively folds and unfolds the first arm segment relative to the boom at the first hinge joint and the second arm segment relative to the first arm segment at the second hinge joint based on air pressure from the air source.
