An objective of the present invention is to operate a threshing device in an operation condition suitable for threshing work by manual thresh feeding when performing threshing work by manual thresh feeding to satisfactorily perform the work, and improve durability. A combine comprises: a restriction member (26) to switch between a restriction release state to manually supply crop stems and a restriction state to restrict supply of the crop stems; a detection sensor to detect the restriction state or the restriction release state; and a threshing control unit to control a drive speed of a threshing device (4) to operate in an operation condition for cutting work if the detection sensor detects the restriction state, and operate in an operation condition for manual thresh feeding if the detection sensor detects the restriction release state. A support member (46) supporting the detection sensor is fixed on a frame body (30) supporting a crop stem return device (11). The restriction member (26) is supported on the support member (46) around a shaft center in a transverse direction to be shaken. Also, shaking around the shaft center switches between the restriction state and the restriction release state. |
