PROBLEM TO BE SOLVED: To provide a technology to further accurately detect a field surface position.SOLUTION: A rice transplanting machine 1 incudes a float (14) detecting a field surface position, and includes a sensor 20 set up separately from the float (14) to detect the field surface position. A detection part 21 of the sensor 20 is set up at a position corresponding to the side of the float (14) and just in front of a planting position P. The detection part 21 of the sensor 20 is set up at a position inner than the outermost width of the float (14). The detection part 21 of the sensor 20 is set up at the backward of a portion projecting to the sideward of the float (14). |
