Summary:To provide a harvesting machine which is capable of, even when a reaping part is replaced, preventing a change in a lowering speed of a reel.SOLUTION: A harvesting machine comprises a reaping part mounted on a machine body and reaping planted grain culm in a field. The reaping part includes a reel for raking the planted grain culm, while rotatingly driving the reel around a reel axis along a lateral width direction, an actuator 4 capable of lifting and lowering the reel, and a lifting/lowering control part 21 for controlling the actuator 4. The machine body is configured to be able to replace the reaping part mounted on the machine body with another reaping part having a different reaping width. When controlling the actuator 4 to lower the reel, the lifting/lowering control part 21 controls the actuator 4 to lower the reel at a constant speed regardless of a reaping width of the reaping part mounted on the machine body.SELECTED DRAWING: Figure 3 【課題】刈取部を付け替えてもリールの下降速度が変化しない収穫機を提供する。【解決手段】機体に取り付けられると共に、圃場の植立穀稈を刈り取る刈取部を備え、刈取部は、横幅方向に沿ったリール軸芯周りに回転駆動しながら植立穀稈を掻き込むリールを有しており、リールを昇降可能なアクチュエータ４と、アクチュエータ４を制御する昇降制御部２１と、を備え、機体は、機体に取り付けられている刈取部を、刈幅の異なる別の刈取部に付け替え可能に構成されており、昇降制御部２１は、リールが下降するようにアクチュエータ４を制御する際、機体に取り付けられている刈取部の刈幅にかかわらず一定の速度でリールが下降するようにアクチュエータ４を制御する。【選択図】図３
