Abstract:
To provide a work vehicle capable of automatically traveling while working in a field in an unmanned state.SOLUTION: A work vehicle is a robot rice transplanter 1 which includes: a pair of left and right rear wheels 4L, 4R for making a traveling vehicle body 2 travel; a planting device 100 connected to the traveling vehicle body; a pair of left and right rear wheel clutches 440L, 440R for putting on and off the drive of the rear wheels; a pair of left and right rear brake devices 450L, 450R for braking the drive of the rear wheels; a positioning device 410 for acquiring positional information; and a control part 400 for making the traveling vehicle body automatically travel on the basis of positional information acquired by the positioning device, and prescribed traveling route information. When the control part determines that a rotation locus during rotation, obtained from the positional information by the positioning device is deviated from the prescribed traveling route information, the control part controls the drive by using the rear wheel clutch or the rear wheel brake device for the one rear wheel of the left and right rear wheels 4L, 4R, on the basis of a deviation state.SELECTED DRAWING: Figure 3
