PROBLEM TO BE SOLVED: To excellently make a turn for transferring among adjacent plural working processes in a crossed state by correctly detecting a position of a machine body to an outer periphery of an unreaped stems group and to make a suitable turn even in the case of the unreaped stems group having heterogeneous shapes. SOLUTION: This reaping harvester performs a working process along an outer periphery of an unreaped stems group and a distance from the unreaped stems group to the outer periphery is detected, then a position of a traveling machine body to the unreaped stems group is detected by a position detecting means 100 according to the detected distance, thus the machine body is made to advancing rotary travel towards a side approaching to the unreaped stems group and is made to make a turn for a working process changing to make a reverse turn traveling to a next working place crossing to the one working process by a controlling means 101 controlling an action of the traveling machine.
