ABSTRACT:
The present invention is directed to an improved breakaway apparatus for a mobile sprayer having at least one spray boom extending outwardly therefrom. The breakaway apparatus has a main plate pivotally mounted to a frame on the vehicle, and coupled by a pivotal link to the spray boom arm with a spring mounted between the main plate and the frame to urge the spray boom arm outwardly from the frame. A shock absorber is pivotally mounted to the frame and to the main plate to absorb loads placed on the spray boom arm when it is pivoted rearwardly relative to the vehicle. A generally lateral stop surface and a cushioned stop are provided on opposed portions of the frame and the main plate, and are aligned to engage when the spray boom arm is pivoted relative to the frame in a forward direction while the spray boom arm is extended for spraying. Preferably, two boom arms are provided which extend in opposite directions, with each spray boom arm having a generally independent breakaway apparatus therefor.
