The horizontal surface of the transparent cover 21 is configured to be substantially flush with the horizontal portions 16b of the right and left covers 16. .

  As shown in FIG. 3, in the right light 20, the upper bulb 22 and the reflector 24 are located on the right side (laterally outside the cutting part 2) from the left and right center of the right light 20, and the lower bulb 23 and the reflector 25 are on the right The light 20 is located from the left and right center to the left side (left and right center side of the cutting unit 2). The reflector 24 is configured to reflect the light of the upper bulb 22 forward, and the reflector 25 is configured to reflect the light of the lower bulb 25 diagonally forward right and diagonally downward. Thereby, in a state where the cutting unit 2 is positioned on the ground, the irradiation range RD1 of the upper bulb 22 and the irradiation range RD2 of the lower bulb 23 of the right light 20 are shown in FIG. 5 (a) and FIG. In such a state, the divider 8 is irradiated by the bulb 23 under the right light 20.

  As shown in FIG. 3, in the left light 20, the upper bulb 22 and the reflector 24 are located on the left side (laterally outside of the cutting part 2) from the left and right center of the left light 20, and the lower bulb 23 and the reflector 25 are left The light 20 is located from the right and left center to the right side (left and right center side of the cutting part 2). The reflector 24 is configured to reflect the light of the upper bulb 22 forward, and the reflector 25 is configured to reflect the light of the lower bulb 25 diagonally forward left and diagonally downward. Thereby, in a state where the cutting unit 2 is positioned on the ground, the irradiation range LD1 of the upper bulb 22 and the irradiation range LD2 of the lower bulb 23 of the left light 20 are shown in FIG. 5A and FIG. In this state, the divider 10 is irradiated by the bulb 23 under the left light 20.

  As shown in FIG. 6, in a state where the cutting unit 2 is positioned on the ground, the left side portion of the irradiation range RD1 of the bulb 22 above the right light 20 and the irradiation range of the bulb 22 above the left light 20 The right side portion of the LD 1 overlaps in front of the cutting unit 2. In this case, the overlapping portion AD is positioned forward from a predetermined short distance (for example, about 2 meters) in the center of the cutting unit 2. As shown in FIG. 5A, the irradiation ranges RD1, RD2, LD1, and LD2 of the upper and lower bulbs 22 and 23 of the right and left lights 20 are oblique in a state where the cutting unit 2 is positioned on the ground. It looks forward and downward.

  As shown in FIG. 5B, when the cutting unit 2 is driven up to the upper limit position, the irradiation ranges RD1, RD2, LD1, LD2 of the upper and lower bulbs 22, 23 on the right and left lights 20 are substantially forward. It will be in a state to face. In this case, the above-described overlapping portion AD (see FIG. 6) is positioned forward from a predetermined long distance (for example, about 8 meters) at the center of the cutting unit 2.

  As shown in FIGS. 1 and 2, a light 18 is attached downward to the front side of the discharge port 12 a of the unloader 12, and a cover 26 that covers the light 18 from the upper side is provided. In a state where the unloader 12 is placed on the cradle 17 (a state where the unloader 12 is disposed at the storage position), the discharge port 12a of the unloader 12 is positioned near the upper front of the dividers 9 and 11. As a result, the range SD immediately before the center of the cutting unit 2 (the vicinity between the overlapping portion AD and the cutting unit 2 described above) (see FIG. 6) is irradiated by the light 18 of the unloader 12.

  As shown in FIG. 4, the light switch 19 is provided in the operation unit 3. When the light switch 19 is operated to the ON2 position, the upper and lower bulbs 22 and 23 of the right and left lights 20 are turned on, and the light 18 of the unloader 12 is turned on. When the light switch 19 is operated to the ON1 position, the bulbs 23 below the right and left lights 20 are turned on, the bulbs 22 above the right and left lights 20 are turned off, and the lights 18 of the unloader 12 are turned on. When the light switch 19 is operated to the OFF position, the upper and lower bulbs 22 and 23 of the right and left lights 20 are turned off, and the light 18 of the unloader 12 is turned off.

In the combine, for example, as shown in FIG. 2, the side of the cutting unit 2 opposite to the driving unit 3 is the non-cutting side A1 (the side where the crop is not yet cut), and the driving unit 3 side of the cutting unit 2 is the cutting side A2 ( The side where the crop has already been cut). In this case, the dividers 9, 10, and 11 are located in the vicinity of the crop stock and are hidden by the crops, and the dividers 9, 10, and 11 cannot be seen from the operation unit 3. On the other hand, the divider 8 is located on the laterally outer side of the row B1 at the end portion of the already-cutted side A2 in the crop on the non-cutted side A1, and the divider 8 can be visually observed from the driving unit 3. The operator of the driving unit 3 operates the combine while visually checking the positional relationship between the row B1 at the end of the already-cutted side A2 and the divider 8 in the crop on the cutting side A1.
In this case, the upper and lower bulbs 22, 23 on the right light 20 irradiate the row B1 at the end of the already-cutted side A2 in the crop on the non-cutted side A1, so the crop on the uncutted side A1 It becomes easy to carry out the operation while visually observing the row B1 at the end of the already cut side A2.

[First Alternative Embodiment of the Invention]
Instead of the above-mentioned [Best Mode for Carrying Out the Invention], a configuration as shown in FIGS. 7 and 8 may be used.

The reflector 24 is configured to reflect the light of the upper bulb 22 forward, and the reflector 25 is configured to reflect the light of the lower bulb 25 diagonally forward right and diagonally downward. Thereby, in the state where the cutting unit 2 is positioned on the ground, the irradiation range RD1 of the upper bulb 22 and the irradiation range RD2 of the lower bulb 23 of the right light 20 are shown in FIG. 5A and FIG. In such a state, the divider 8 is irradiated by the bulb 23 under the right light 20.

  As shown in FIG. 7, in the left light 20, the upper bulb 22 and the reflector 24 are positioned from the left and right center of the left light 20 to the right side (the left and right center side of the cutting unit 2), and the lower bulb 23 and the reflector 25 are The left light 20 is located on the left side (laterally outside of the cutting unit 2) from the left and right center. The reflector 24 is configured to reflect the light of the upper bulb 22 forward, and the reflector 25 is configured to reflect the light of the lower bulb 25 diagonally forward left and diagonally downward. Thus, in a state where the cutting unit 2 is positioned on the ground, the irradiation range LD1 of the upper bulb 22 and the irradiation range LD2 of the lower bulb 23 of the left light 20 are shown in FIG. 5 (a) and FIG. In this state, the divider 10 is irradiated by the bulb 23 under the left light 20.
