PROBLEM TO BE SOLVED: To improve the accuracy, operating efficiency and working efficiency in directional control. SOLUTION: This harvester is designed to carry out the directional control by gradually decreasing the turning radius according to an increase from a small detected value with a sensor of a detecting means 11 to a larger detected value in the automatic directional control of the harvester performed by turning a travel device 2 with the detecting means 11 capable of detecting the presence or absence and the extent of a shift of the machine forward direction installed is a machine body.
