It is possible to save energy by illuminating with only one of the 32. Both the first headlight 31 and the second headlight 32 can be turned off.

[Irradiation direction and irradiation range]
As shown in FIGS. 11 and 12, the optical axis 31C of the first headlight 31 is configured to face inward in the body width direction with respect to the optical axis 32C of the second headlight 32, and the second front The optical axis 32C of the illuminating lamp 32 is configured to face the outside in the width direction of the machine body with respect to the optical axis 31C of the first headlight 31. Further, in the working state, the second headlight 32 is arranged so that the optical axis 32C of the second headlight 32 faces downward from the optical axis 31C of the first headlight 31. The first headlight 31 located higher than the second headlight 32 can illuminate a distant area in front of the aircraft, and the second headlight 32 located closer to the field than the first headlight 31. Therefore, it is possible to brightly illuminate the part close to the aircraft.

Specifically, the optical axis 31C of the first headlight 31 faces inward in the width direction of the aircraft at an inclination angle of 5 degrees with respect to the front of the aircraft, and the optical axis 31C of the aircraft 1 has an inclination angle of 3 degrees with respect to the front of the aircraft. It is provided so that it faces downward.

The optical axis 32C of the second headlight 32 faces the outside in the width direction of the aircraft at an inclination angle of 16 degrees with respect to the front of the aircraft, and faces the underside of the aircraft 1 at an inclination angle of 19.5 degrees with respect to the front of the aircraft.

Even if the crop is a long headlight, the inside is illuminated by the first headlight 31 which is installed at a position higher than the second headlight 32 and is less likely to be in the shadow of the planted grain headlight, and the first headlight. 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 field can be illuminated evenly and efficiently.

Since the first headlight 31 configured so that the optical axis 31C faces inward in the width direction of the aircraft is arranged above the second headlight 32, the first headlight 31 is used. The floodlight is not easily blocked by the tips of the planted culms, and it is easy to visually recognize the growth state and field conditions of the planted culms immediately before the cutting section, which is the target of cutting. Further, since the illumination range 31D of the first headlight 31 is wider than the irradiation range 32D of the second headlight 32, it is possible to more illuminate the planted culm or the field to be cut.

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 width of the cutting portion 10, it is easy to visually recognize the growing state of the planted culm and the state of the field within the cutting width.

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 mowed land to be cut are used. It is easy to see the boundary between the planted culms that are the target of cutting and the planted culms in the uncut land.
