    Abstract: [Problem] To enable high-precision work by causing the halting of travel before an autonomous travel work vehicle deviates from a set travel path.
    [Solution] 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.

    Abstract: In a working vehicle 141, there is dissolved a risk that a black smoke is discharged, a knocking is generated and an engine stall is caused, if a lot of load is applied to a rotary tiller 24 during various works while traveling at a low speed. In the working vehicle 141 provided with an engine 70 which is mounted to a travel machine body 142, a common rail type fuel injection device 117 which injects fuel to the engine 70, and a continuously variable transmission 159 which shifts power from the engine 70, an engine driving point Q (Q1 → Q2) relating to a rotating speed N and a torque T of the engine 70 is changed in such a manner that the rotation speed come to a high speed side rotating speed N2 dissolving an overload, and a change gear ratio of the continuously variable transmission 159 is modified and regulates in such a manner that a vehicle speed V of the travel machine body 142 does not change in the case that the overload acts on the engine 70 of having a low speed N1 in the rotating speed N.
