PROBLEM TO BE SOLVED: To solve the problem that care has to be exercised for avoiding errors in operation though constitution can be simplified by standardizing mechanisms such as delivery rolls, in a model of spraying an application agent and discharging a residual application agent in a hopper by delivering the application agent in the hopper by rotation of a delivery roll. SOLUTION: In a spray machine delivering an amount of the application agent depending on vehicle speed and spraying the application agent, a spray switch 2 for controlling spraying by rotatively driving the delivery roll 1 depending on the vehicle speed and a discharge switch 3 for controlling discharge of the residual amount of application agent by driving the delivery roll 1 are installed. During spraying operation, the application agent held in the hopper is sprayed to a traveling field surface or the like by driving the delivery roll 1 by operating the spray switch 2 to deliver the application agent to a spray boom. When the residual application agent in the hopper is separately discharged to a vessel or the like after the spraying operation, the discharge switch 3 different from the spray switch 2 is operated.
