SOLUTION: The chemical tank 2 filled with the chemical; and a spraying boom having a plurality of spraying nozzles are provided on the spraying working vehicle. Further, at usual work, a water-intake unit 11 for pumping up water from a water source is connectably constituted on a chemical spray pump 5 for feeding the chemical in the chemical tank 2 to the spraying boom.
