PROBLEM TO BE SOLVED: To obtain a self-traveling spraying machine, in which traveling of this type of unstable self traveling is improved and stable traveling can be obtained, by lowering the center of gravity of the whole machine without changing the winding amount of a hose. SOLUTION: In this self-traveling spraying machine, when a hose 7 is wound by a hose winder 19, the hose 7 is wound based on a hose part fixed on the power sprayer side and an undercarriage 1 is backed and an agent is sprayed while the undercarriage 1 is backed. In the spraying machine, a drum outside diameter of the hose winder 19 is formed in a size close to the width of the undercarriage 19 and a drum length is formed in a length close to longitudinal length of the hose winder-carrying space and the hose winder 19 is installed in the direction of vertical shaft at a downward position of the undercarriage 1 as much as possible and the hose 7 is wound at a position moved from the rear center of the undercarriage 1 to the side of the undercarriage 1 by a hose- guiding mechanism 20 which longitudinally carries out reciprocating motion.
