<P>PROBLEM TO BE SOLVED: To enable the on-off control of a clutch of a reaping and threshing system to be simply and lightly carried out by utilizing a cam mechanism driven by an electrically driven motor, and to enable the cam mechanism to be also utilized for the on-off control of a clutch for unloading grain. Ž<P>SOLUTION: A position (a) at which a clutch 50 for unloading grains is in an on-state and a reaping clutch 30 is in an off-state is set in one side operation region, and a position (c) at which the clutch 50 for unloading grains is in the off-state and the reaping clutch 30 is in the on-state is set in the other side operation region so as to hold a neutral position N at which the reaping clutch 30 and the clutch 50 for unloading grains are both kept in the off-state in a cum mechanism 8 enabling the rotation direction to be switched to the normal rotation direction and the reverse rotation direction by an electrically driven motor 70.
