In this study, the spray equalization of the fertilizer distributor was analyzed using DEM simulation. The fertilizer distributor consists of the hopper, shutter, frame, scatter plate, and blade. The operating method is as follows: the dropped solid fertilizer from the hopper was scattered by the blade and the scatter plate. At that time, the amount of fertilizer was regulated by the opening and closing of the shutter hole. The simulation was conducted to analyze the sprayer equalization of the fertilizer distributor with the angle of shutter and the number of shutter holes set as the experimental factor.
