PROBLEM TO BE SOLVED: To provide a combine harvester in which standard number of revolutions of an engine is made to be changeable according to conditions even during setting of an accelerator automatic control function. SOLUTION: In the combine harvester, a controller 200 capable of automatically setting a throttle valve opening of the engine 10 to a previously set opening according to each operation item by every operation items (when traveled, when threshed and when unhulled rice is discharged) is installed. In the controller 200, a means in which throttle valve opening is changeable during operation in a target number of revolutions of engine corresponding to a specific item is installed. Since the target number of revolutions of engine is made to be changeable, operation range can be changed and accelerator automatic control properties of the combine harvester are improved compared with a conventional combine harvester.
