PROBLEM TO BE SOLVED: To exactly turn a combine harvester by excellently performing the rotating adjustment of a case of a differential mechanism even if the combine harvester runs at a slow speed running state. SOLUTION: This combine harvester can be turned by synthesizing the input of the rotating drive power from a hydraulic transmission 16 for running and a hydraulic transmission 61 for turning in the differential mechanism 50, by outputting the the rotating drive power synthesized and by activating right and left axles 37, 37'. A power transmission interruption device 65 is provided on a control shaft 56 and the control shaft 56 is rotatably driven from the hydraulic transmission 61 for turning by operating the power transmission interruption device 65 based on the turn operation. The rotating drive power is input to a driven gear 55 on the outer circumference of the differential mechanism 50, and the right and left axles 37, 37' are activated by the synthetic output from the differential mechanism 50, thereby turning the combine harvester.
