PROBLEM TO BE SOLVED: To perform work favorably by operating a threshing device in a suitable operation state for manual threshing work in manual threshing work and improve durability.SOLUTION: A combine includes: a restriction member 26 capable of being switched between a restriction cancellation state enabling grain culms to be supplied manually and a restriction state restricting supply of grain culms； a detection sensor detecting whether the combine is in the restriction state or restriction cancellation state； and a threshing control unit controlling a drive speed of a threshing device 4 such that the combine is brought into an operation state for reaping work when the restriction state is detected by the detection sensor and an operation state for manual threshing work when the restriction cancellation state is detected by the detection sensor.SELECTED DRAWING: Figure 3【課題】枕扱ぎ作業の際には、枕扱ぎ作業に適した運転状態で脱穀装置を作動させることにより作業を良好に行えるようにしながら、耐久性の向上を図る。【解決手段】手動での穀稈の供給を可能にする規制解除状態と穀稈の供給を規制する規制状態とに切り換え自在な規制部材２６と、規制状態であるか規制解除状態であるかを検出する検出センサと、検出センサが規制状態を検出すると刈取作業用の運転状態になり、検出センサが規制解除状態を検出すると枕扱ぎ用の運転状態になるように、脱穀装置４の駆動速度を制御する脱穀制御部とが備えられている。【選択図】図３
