A vehicle mounted fluid spreading apparatus including a fixed spray bar having an extender spray bar mounted on each of the opposite ends thereof by means of swing joints so that each of the extender spray bars are movable about a single angularly disposed axis between extended and stowed positions. The spray bars and the swing joints have dual fluid flow passages formed therethrough so that fluid under pressure from a fluid supply is serially recirculated through the spray bars and swing joints back to the fluid supply when the apparatus is in a standby mode, and is sprayingly applied by actuator controlled self-adjusting nozzles mounted in the spray bars when the apparatus is in the operating mode.
