WIPO Patent Application WO/2019/124463

A1

[Problem] To provide an automatic travel work machine that can accurately receive a positioning signal from a navigation satellite and automatically travel a travel route without deviating therefrom, even on an inclined slope. [Solution] The present invention comprises: a traveling machine body 1; a positioning receiver 4 that receives a positioning signal from a navigation satellite; an automatic travel control device that automatically travels along a travel route on the basis of the positioning signal; an inclination detection part that detects the inclination of the traveling machine body 1 and outputs inclination angle information; an inclination angle determination part that determines an inclination angle on the basis of the inclination angle information; and a rotation control mechanism 5 that rotates the positioning receiver 4 with at least one degree of freedom. The rotation control mechanism 5 keeps the positioning receiver 4 horizontal on the basis of the inclination angle.
