<P>PROBLEM TO BE SOLVED: To provide a combined harvester which can well adjust the speed of the vehicle so that the crop-conveying quantity for a thresher is proper. <P>SOLUTION: The combined harvester includes threshing electric motors M2, M3 for driving a thresher, an electric power-supplying means for supplying electric power to the threshing electric motors M2, M3, a travel device-driving means D for driving a travel device, and a control means H for controlling the operation state of the threshing electric motors M2, M3 and the operation state of the travel driving means D. The control means H controls the operation state of the travel driving means D so as to decrease the speed of the vehicle, when the driving loads of the threshing electric motors M2, M3 detected with a load-detecting means F are larger than set quantities, and so as to increase the speed of the vehicle, when the driving loads of the threshing electric motors M2, M3 are smaller than set quantities. <P>COPYRIGHT: (C)2013,JPO&INPIT |
