TRAVELLING WORK MACHINE

A traveling work machine includes: a machine body provided with a travel apparatus; a position detection unit capable of detecting position information of the machine body on the basis of a positioning signal of a navigation satellite; a travel trajectory obtainment unit capable of obtaining a travel trajectory of the machine body on the basis of detection, over time, of the position information; a target heading calculation unit that calculates a target heading on the basis of the travel trajectory; a maneuvering control unit capable of controlling the travel apparatus to maneuver along the target heading; and a single operating tool capable of setting both a start point and an end point of the travel trajectory obtained when calculating the target heading.
