PROBLEM TO BE SOLVED: To provide a combine harvester that can increase the efficiency of turning operation of the machine body in a field headland or the like. SOLUTION: In a combine harvester that is equipped with a hydraulic variable-speed driving mechanism (25) that can turn the machine body by allowing the driving speeds of the left and right running crawlers (2) (2) to differ from each other, a single steering lever (19) that can change the moving speed only by inclining the variable-speed driving mechanism (25) with an inclination operation toward a one direction. At the same time, the reaping part (8) can be operated upward or downward by inclining the steering lever (19) toward different direction. Further, the steering lever (19) is made freely exchangeable with another round shape steering handle (145). COPYRIGHT: (C)2006,JPO&NCIPI
