<p>PROBLEM TO BE SOLVED: To provide a combine harvester in which an engine can be miniaturized, fuel consumption is less, and exhaust gas is less exhausted.SOLUTION: The combine harvester is provided with an engine threshing driving clutch (10) for connecting/disconnecting driving force from an engine (1) to a threshing device (25), load determination means for determining a load condition of the engine (1), and threshing driving motor (2) for directly driving the threshing device (25). When the load determination means determines a low load condition, the rotation speed of the engine (1) is automatically lowered, and the engine threshing driving clutch (10) is disconnected so that the threshing device (25) is driven only by a driving force of the threshing driving motor (2).</p> |
