Abstract: An automatic travel system for a work vehicle allows the work height of a work device to be easily and appropriately adjusted by a remote operation that uses a remote operation device for a work vehicle during automatic travel. The automatic travel system for work vehicles includes an automatic travel unit, and a remote operation device, for a work vehicle. A work vehicle has a work height setting unit, a height detector, a raising and lowering indicator, and a raising and lowering control unit, for a work device. The raising and lowering control unit sets a control target height to a work height on the basis of the indication of the raising and lowering indicator and executes automatic raising and lowering control so that the height position of a work device matches the work height. The remote operation device has a display device that displays remote operation information, and a work height adjustor that allows adjustment of the work height while in automatic travel mode. The display device has a work height display section that displays the work height of the work device, the work height after adjustment, and the height position of the work device.

The automatic travel system for work vehicles includes an automatic travel unit, and a remote operation device, for a work vehicle.

The raising and lowering control unit sets a control target height to a work height on the basis of the indication of the raising and lowering indicator and executes automatic raising and lowering control so that the height position of a work device (6) matches the work height. The remote operation device has a display device that displays remote operation information, and a work height adjustor that allows adjustment of the work height while in automatic travel mode. The display device has a work height display section that displays the work height of the work device, the work height after adjustment, and the height position of the work device.
