<p><P>PROBLEM TO BE SOLVED: To provide a combine harvester contributing to conservation of dwelling environment by reduction of fuel consumption, reduction of noise generated from an engine and cleaning of atmosphere by exhaust gas reduction, improving efficiency of grain discharging work and improving total efficiency of harvesting work. <P>SOLUTION: The combine harvester is provided with a transmission switching device (69) to switch driving power of the engine (68) inputted through a discharge clutch (95) and driving power of an electric motor (83) inputted without interposing the discharge clutch (95) and output the driving power of the power source having higher rotational speed to a grain discharging device (5a), and a controller (111) to automatically couple the discharge clutch (95) when the driving rotational speed of the grain discharging device (5a) is lowered in a state of driving the grain discharging device (5a) by the driving force of the electric motor (83). <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
