PROBLEM TO BE SOLVED: To solve a problem that, when a wet fertilizer received in the hopper of a fertilizer applicator is applied, the fertilizer adheres to the side wall of the hopper and can therefore perfectly not be applied. SOLUTION: A brush arm 45 to which a brush 50 is fixed is connected to a rotation shaft 41 projectedly disposed in the hopper 27. The brush 50 is disposed along the side wall 27a of the hopper 27, and slides on the side wall 27a by the rotation of the rotation shaft 41 and the brush arm 45 to scrape off and clean the fertilizer adhered to the side wall 27a.
