PROBLEM TO BE SOLVED: To provide a combine harvester which can properly perform a ridge-matching operation along an un-reaped grain straw row with a manual switch in the time of a harvesting work, prevent the turning of the combine harvester by the error operation of the manual switch in the time except the harvest work, and improve driving operability, handleability and the like. SOLUTION: This combine harvester whose right and left travel crawler revolution numbers are differentiated from each other by the rotation operation of a steering wheel and also by the operation of the manual switch to laterally slowly turn the combine harvester is characterized in that the operation of the manual switch is ignored on the detection result of a reaping sensor for detecting whether the reaping portion is driven or not.
