PROBLEM TO BE SOLVED: To provide precise steering control so as not to trample down crops with wheels in an agricultural working vehicle autonomously traveling by control over a traveling position adopting a global positioning system (GPS) and traveling a field during raising of the crops. SOLUTION: The agricultural working vehicle is loaded with the GPS, an inner sensor 122 and plant profiling sensors 201 and autonomously carries out working. In the working vehicle, a GPS antenna 108 is arranged between front wheels 7 and 7 and rear wheels 8 and 8 in the front and rear directions and above a point P located in the left and right nearly center of the vehicle in the left and right directions and the plant profiling sensors 201 are arranged in the forefront part of the vehicle. The plant profiling sensors 201 and 201 are arranged in front of the left and the right front wheels 7 and 7, respectively and liftably and lowerably mounted through a link 206 (or a lifting and lowering link mechanism 37) relatively to main frames 6L and 6R. Furthermore, a float 202 is provided under the plant profiling sensors 201. COPYRIGHT: (C)2004,JPO |
