PROBLEM TO BE SOLVED: To provide a harvester in which a grain discharging device is activated and a work device for performing a grain harvesting operation is activated. SOLUTION: A clutch operating unit 70 is separately linked with a first clutch and a second clutch, and switches the first clutch and the second clutch between a transmission state and a non-transmission state by rotating operation. The clutch operating unit 70 includes a neutral state in which both the first clutch and the second clutch are in the non-transmission state and a second state in which the first clutch is in the transmission state by rotating from the neutral state to one side. A first state in which the clutch is held in a non-transmission state and a second state in which the first clutch is switched to the transmission state and the second clutch is switched to the transmission state by rotating from the neutral state to the other side can be revealed. It is configured.
