PROBLEM TO BE SOLVED: To provide a fertilizer spreader having a simple configuration without enlarging the fertilizer spreader, having a fertilizer mixing function, and suppressing the vertical height low.SOLUTION: A speed change gear part 5 provided below a spreader part 4 includes: a first bevel gear 52 fixed to the inside of a case 50 of a horizontal input shaft 51； a first rotary shaft 54 to which a second bevel gear 53 to be engaged with the first bevel gear is fixed and which is vertically installed； and a second rotary shaft 55 vertically installed in parallel to the first rotary shaft 54. The first rotary shaft 54 has two upper/lower gears with the different number of teeth, and a gear engaged therewith is fixed to the second rotary shaft 55 and a spreading plate rotary shaft 56 provided coaxially with the second rotary shaft 55. The spreading plate rotary shaft 56 is externally fitted around the second rotary shaft 55 and rotatably provided to the second rotary shaft 55. One ends of both shafts are extended outward the case 50, an agitator 6 is connected to the second rotary shaft 55 outside the case 50, and a spreading plate 40 is fixed to the spreading plate rotary shaft 56.【課題】肥料散布装置を大型化させることなく構造が簡単で、肥料混合機能を有し、上下方向の高さを低く抑えた肥料散布機を提供する。【解決手段】散布部４下方に設けた変速部５は、水平方向の入力軸５１のケース５０内に固着された第１ベベルギヤ５２と、これと歯合する第２ベベルギヤ５３が固着され垂設された第１回転軸５４と、これと平行に垂設された第２回転軸５５とが設けられ、第１回転軸５４には歯数の異なるギヤが上下２個設けられ、これと歯合するギヤが第２回転軸５５と、第２回転軸５５と同軸上に設けた散布板回転軸５６に固着され、散布板回転軸５６は第２回転軸５５に外嵌されるとともに第２回転軸５５に対し回転自在に設けられ、双方の一端がケース５０外に延設され、ケース５０外の第２回転軸５５にはアジテータ６が連結され、散布板回転軸５６には散布板４０が固着されている肥料散布機による。【選択図】図４
