The first headlight 31 and the second headlight 32 are provided at a position lower than the light 31, and when the front is illuminated, the outside is illuminated by the second headlight 32, which may be a shadow of a long headlight 32. By making good use of the fact that the heights of the headlights are different up and down, the fields can be illuminated evenly and efficiently.

Since the first headlight 31 is located above the second headlight 32, its floodlight is less likely to be blocked by the tips of the planted grain culms. By directing the optical axis 31C of the first headlight 31 toward the inside in the width direction of the machine body with respect to the optical axis 32C of the second headlight 32, the illumination range 31D of the first headlight 31 is second. It faces inward in the width direction of the aircraft from the irradiation range 32D of the headlight 32. The first headlight 31 makes it easier to visually recognize the growing state of the planted culm immediately before the cutting section 10 and the state of the field, which are the targets of cutting.

The left and right first headlights 31 are arranged so as to cover the entire width of the cutting portion 10 in front of the machine body by both lighting ranges 31D. Since the front of the machine body is illuminated by the left and right first headlights 31 over the entire width of the cutting portion 10, it is easy to visually recognize the growing state of the planted culm within the cutting width and the state of the field.

At least one of the first headlight 31 or the second headlight 32 illuminates a part of the weeding tool 12, preferably the tip portion, so that the planted culm and the cut land to be cut are used. It is easy to see the boundary between the planted culm and the planted culm of the uncut land.
