(Effect of the Invention) In summary, the present invention is a fertilizer applicator that pumps liquid fertilizer from a fertilizer tank installed on a traveling machine by a fertilizer pump to apply fertilizer. The transmission is provided in the vicinity of the side surface of the traveling wheel, and the transmission is arranged so as to face the traveling wheel in an inclined manner so that the gear shift operation lever projecting obliquely downward from the case of the transmission can be hidden below the case. Since it is configured, the fertilizer pump below the fertilizer tank can be located at a position close to the fertilizer tank with a small drop, and the fertilizer application can be performed smoothly. Even if the transmission of the fertilizer pump is located near the side surface of the traveling wheel, the transmission arranged diagonally downward toward the traveling wheel has a gearshift operation lever that protrudes obliquely downward to the side below the casing of the transmission. Since it is hidden in, the gear shift operation lever is not soiled by dirt falling from the traveling wheels. For this reason, the shift operation of the fertilizer pump can be comfortably performed, and the work can be performed efficiently always with an appropriate fertilizer application amount.
