Therefore, when the liquid fertilizer is replenished from the fertilizer replenishing ports 50a and 50a, the hand suddenly goes out of order and the fertilizer falls on the upper surface of the tanks 50 and 50 outside the fertilizer replenishing port, or the fertilizer replenishing port is oversupplied. Even if the tanks 50 / 50a overflow from the tanks 50 / 50a, the weirs 50c / 50c provided on the tank upper surface prevent the fertilizer on the tank upper surface from falling onto the machine body. The fertilizer is prevented from flowing down on the machine body, and the blocked fertilizer is guided to the outside of the machine body and flows out of the machine body. Incidentally, the tank 50
The shape of the weirs 50c and 50c provided on the upper surface of the tank 50 is not limited, and for example, as shown in FIG. The outer peripheral walls 50f and 50f may be separately formed from the tank and attached as a weir. Further, since the inclined surfaces 50e and 50e are formed on the upper surfaces of the tanks 50 and 50 so as to be lower toward the outside of the machine body, the fertilizer on the tank upper surface easily flows out of the machine body.

An empty tank 50, 50 prior to the start of work
The fertilizer in the tank 50/50 decreases when the fluid fertilizer is supplied into the tank or as the work progresses, and the fertilizer is further supplied to the tank 50.
-When replenishing in 50, this agricultural working machine with a fertilizer application has the following actions and effects. That is, in this agricultural working machine with a fertilizer application, the tanks 50, 50 for storing the fluid fertilizer are arranged such that a part of the tank 50 is outside the machine body and the other part is located on the machine body.
Since the fertilizer supply ports 50a and 50a are provided on the upper surface of the tank 50, and the weir portions 50c and 50c that stop the fertilizer on the tank upper surface from flowing down onto the machine body are provided on the tank upper surface, When replenishing fluid fertilizer from the fertilizer replenishing ports 50a and 50a provided on the upper surface of the fertilizer, the hand suddenly goes out of hand and the fertilizer falls onto the tank upper surface outside the fertilizer replenishing port, or the fertilizer replenishing port 50a is excessively replenished.
・ Even if it overflows from 50a to the upper surface of the tank, the weir 50c provided on the upper surface of the tank prevents the fertilizer on the upper surface of the tank 50 ・ 50 from flowing down onto the machine body.
Since 50c stops, the fertilizer is prevented from flowing down on the airframe, and the problem that the fertilizer corrodes the airframe components is prevented.
