Abstract
An autonomous travel work vehicle (1), which is provided with a position calculation means that measures the device body position by means of a satellite positioning system, a steering actuator (40) that operates a steering device, an engine rotation control means, a transmission means (44), and a control device (30) that controls each of same, is caused to autonomously travel, along a set travel path stored in the control device (30), by an accompanying travel work vehicle (100) that works while accompanying the travel of the autonomous travel work vehicle (1) by means of attended operation and that is mounted with a remote operation device (112) that can operate the autonomous travel work vehicle, and the control device (30) halts autonomous travel when a signal disruption from the satellites, a large deviation from the set travel path, an abnormal sensor value, fuel exhaustion, or the like is detected.
