Abstract

A sprayer having a folding boom is disclosed which includes a main spray bar mounted at the rear end of a small vehicle or a trailer. First and second intermediate boom sections are pivotally connected, about horizontal axes, to the outer ends of the means spray bar and have wheels at the outer end thereof so that the intermediate boom sections will remain positioned above the ground regardless of the terrain encountered by the sprayer. First and second outer boom sections are pivotally mounted, about horizontal axes, to the outer ends of the intermediate boom sections. The outer boom sections may be folded onto the intermediate boom sections and when the outer boom sections are so folded, the spray nozzles thereon are rendered inoperative. The intermediate boom sections, with the outer boom sections folded thereon, may also be moved to a folded position relative to the vehicle. When the intermediate boom sections have been so folded, the spray nozzles thereon are rendered inoperative.
