The present invention is to construct a fertilizer spreader that is used as a farming machine for spraying fertilizers in rural areas, and to spread and spray the fertilizer supplied from the fertilizer container by blowing air, and also used as a cleaner to blow leaves and blow other winds. The present invention relates to a multi-purpose fertilizer spreader that has been improved to be used for various purposes such as wind blowing, and is mounted on the backrest 20 so that a user directly carries and blows a blowing fan 15 that generates strong wind while rotating by driving the engine 10. To form a sprayer 30 for collecting and discharging the strong wind generated in the blower fan 15, and communicating with the sprayer 30 above the blower fan 15 and adjusting the fertilizer supply amount 40. At the top, the fertilizer inlet is formed at the top to store the fertilizer, and the fertilizer canister 50 is formed at the bottom of the outlet. , The fertilizer supply port 40 for attaching and removing the fertilizer container 50 is sealed with a closed cap 60 so that strong wind generated from the blowing fan 15 is discharged to the injector 30 to blow off the fallen leaves. It is configured to be used as a vacuum cleaner, so that users do not have to use a separate farming equipment, and the fertilizer container, engine blower fan, and sprayer are sprayed by the user directly, and there is no need to use a separate farming machine. It is easy to spread and it is convenient to use in the terrain of Korea. When not spraying fertilizer, the fertilizer supply port is sealed and the wind generated from the blowing fan is used for cleaning or various other purposes. New economically useful, economical effects that can be used for other purposes during the off-season.
