Abstract
A spray assembly for a working machine that includes a fluid storage tank includes a plurality of nozzle assemblies, each of which includes a direct acting valve. The spray assembly also includes a controller that is operatively connected to each of the direct acting valves for controlling the opening and closing of the direct acting valves, and a selector that is operatively connected to the controller. The selector may be employed by an operator of the working machine to selectively operate one or more of the direct acting valves in order to provide a desired spray pattern of fluid from the fluid storage tank.
