  Further, since the drive cutter 61 is further provided with a driven cutter 62 that is arranged side by side with the drive cutter 61 overlapped and moves up and down integrally with the drive cutter 61, the driven cutter 62 uses the drive cutter 62. It is possible to receive the outer peripheral side (blade edge side) of 61 and to prevent the drive cutter 61 from swinging on the outer peripheral side (blade edge side). Accordingly, the cutting surface of the drive cutter 61 can be made constant and the cutting surface can be made uniform.

  In the embodiment, the harvesting working unit 13 pulls out the headed vegetables A and sandwiches the headed part A1, and transports the headed part A1 to the rear, and the headed part A1 after the cutting of the rhizome part A2 is pulled out. The lifting device 15 is separated from the lifting device 15 and is transported upward and obliquely upward. The lifting device 15 is fixedly provided on the traveling machine body 2, and the pulling and conveying device 14 is disposed in front of the traveling machine body 2. Since it is mounted on the part so as to be movable up and down, the mechanism (in this case, the hydraulic cylinder 22) for moving the pulling and conveying device 14 up and down can be miniaturized, and the cost of parts can be reduced.

  In addition, since the depression angle θ formed by the pulling and conveying device 14 and the lifting device 15 is set to an obtuse angle, the pulling and conveying device 14 is laid as close to the field as possible, and the headed vegetable A in the field is carefully treated. It becomes easy to pull out. For this reason, the possibility of damaging the headed vegetables A can be reduced, and the product value can be improved.
