To enhance the degree of freedom of control of an electric motor for driving a dust suction fan.SOLUTION: A harvester comprises: a conveying device comprising a conveying case, and for conveying reaped grain culms in the conveying case; a dust discharge device comprising a rotating fan to be driven by the power of an electric motor 32, connected to the conveying case, and for sucking dust in the conveying case by the rotation of the rotating fan to discharge it to the outside of the conveying case; a control device 40 for controlling the electric motor 32; and a rotation number sensor 41 for detecting the number of rotations per unit time of the rotating fan. The control device 40 controls the rotation of the electric motor 32 on the basis of a detected value of the rotation number sensor.SELECTED DRAWING: Figure 5 【課題】吸塵ファンを駆動する電動モータの制御の自由度を高くする。【解決手段】搬送ケースを有し、搬送ケース内で刈取穀稈を搬送する搬送装置と、電動モータ３２の動力によって駆動する回転ファンを有するとともに搬送ケースに接続され、回転ファンの回転によって搬送ケース内部の塵埃を吸引して搬送ケースの外部に排出する排塵装置と、電動モータ３２を制御する制御装置４０と、回転ファンの単位時間あたりの回転数を検出する回転数センサ４１と、が備えられ、制御装置４０は、回転数センサの検出値に基づいて電動モータ３２の回転を制御する。【選択図】図５
