The former of the above-mentioned conventional fertilizer spreaders does not have a shutter on the fertilizer dispensing part at the bottom of the hopper, which causes the inconvenience of fine particles of fertilizer falling and flowing out when not in the process of spreading. It was hot. In addition, in the latter type, the traveling operation mechanism and the drive operation mechanism of the stirring device are configured to always work together, so that the fertilizer in the hopper is constantly being stirred while the machine is running. With compound fertilizers, etc., there is a problem in that coarse particles are pushed up to the top and fine particles settle to the bottom, causing a bridging phenomenon in the fertilizer hopper. In addition, in the case of granular fertilizers, if the fertilizer becomes fine and powdered due to over-mixing, even a small amount of moisture can stick to the stirring blades or clog the feeding holes, inhibiting normal dispersion. There were problems such as overloading the engine.
