PROBLEM TO BE SOLVED: To enable a power-transmitting device for transmitting the power of an engine to an auger to be operated so as to be exchanged between a power-transmitting state and a power-intercepting state in a state in which the auger is housed in a housing position. SOLUTION: When the housing state in which the auger is housed in the housing position is detected, the power-transmitting device is changed to the power-transmitting state by the action of an electrically driven actuator caused by the indication of unloading operation by a manually operated indication means when the engine is in an operation-stopping state, and the power- transmitting device is changed to the power-intercepting state by the action of the electrically driven actuator by the indication of stopping the unload. When the engine is in the operating state, the electrically driven actuator is not driven, and the power-transmitting device is not changed to the power- transmitting state even if the indication of the unloading operation is indicated by the manually operating indication means.
