In the upper part of the right and left covers 16, openings are formed at the corners extending from the front part 16a and the lateral part 16b of the right and left covers 16, and the lights 18 are fitted into the openings of the right and left covers 16. The light 18 includes a bulb 18a and a reflector 18b (reflecting plate). Openings connected to the openings of the right and left covers 16 are formed on the right and left lateral sides of the cover 17, and the lights 19 are fixed so as to be fitted into the right and left openings of the cover 17. The light 19 includes a bulb 19a and a reflector 19b (reflecting plate).

図１，３，６に示すように、右のライト１８，１９（右のカバー１６の開口部及びカバー１７の右の開口部）を覆う透明のカバー２０（正面視横Ｌ字状）が取り付けられ、左のライト１８，１９（左のカバー１６の開口部及びカバー１７の左の開口部）を覆う透明のカバー２０（正面視横Ｌ字状）が取り付けられている。カバー２０の前面が右及び左のカバー１６の前部１６ａ及び引き起し装置１３の前面と略同一面（又はカバー２０の前面が右及び左のカバー１６の前部１６ａ及び引き起し装置１３の前面よりも少し後側）に位置するように構成されており、カバー２０の横面が右及び左のカバー１６の横部１６ｂと略同一面に位置するように構成されている。   As shown in FIGS. 1, 3, and 6, a transparent cover 20 (horizontal L shape in front view) that covers the right lights 18 and 19 (the opening of the right cover 16 and the right opening of the cover 17) is attached. A transparent cover 20 (horizontal L shape in front view) that covers the left lights 18 and 19 (the opening of the left cover 16 and the left opening of the cover 17) is attached. The front surface of the cover 20 is substantially flush with the front portion 16a of the right and left covers 16 and the front surface of the pulling device 13 (or the front surface of the cover 20 is the front portion 16a of the right and left covers 16 and the pulling device 13). The lateral surface of the cover 20 is configured to be substantially flush with the lateral portions 16b of the right and left covers 16.

右のライト１８においてリフレクタ１８ｂはバルブ１８ａの光を右及び左斜め前方に反射し、斜め前方下方に反射するように構成されており、右のライト１９においてリフレクタ１９ｂはバルブ１９ａの光を前方に反射するように構成されている。これにより、刈取部２を地面に位置させている状態において、右のライト１８の照射範囲ＲＤ１及び右のライト１９の照射範囲ＲＤ２は図５（ａ）及び図７に示すような状態となるのであり、右のライト１８によりデバイダ８が照射されている。この場合、右のライト１９の照射範囲ＲＤ２は前向きの比較的狭い範囲を照射する状態となるのであり、右のライト１９のバルブ１９ａの光があまり拡散しないことによって、右のライト１９の照射範囲ＲＤ２は比較的明るいものとなる。   In the right light 18, the reflector 18b is configured to reflect the light of the bulb 18a diagonally forward to the right and left, and to be reflected diagonally forward and downward. In the right light 19, the reflector 19b forwards the light of the bulb 19a forward. It is configured to reflect. Thereby, in the state where the cutting unit 2 is positioned on the ground, the irradiation range RD1 of the right light 18 and the irradiation range RD2 of the right light 19 are in the state as shown in FIG. 5A and FIG. Yes, the divider 8 is illuminated by the right light 18. In this case, the irradiation range RD2 of the right light 19 is in a state of irradiating a relatively narrow forward range, and the light of the bulb 19a of the right light 19 is not diffused so much that the irradiation range of the right light 19 RD2 is relatively bright.

左のライト１８においてリフレクタ１８ｂはバルブ１８ａの光を左及び右斜め前方に反射し、斜め前方下方に反射するように構成されており、左のライト１９においてリフレクタ１９ｂはバルブ１９ａの光を前方に反射するように構成されている。これにより、刈取部２を地面に位置させている状態において、左のライト１８の照射範囲ＬＤ１及び左のライト１９の照射範囲ＬＤ２は図５（ａ）及び図７に示すような状態となるのであり、左のライト１８によりデバイダ１０が照射されている。この場合、左のライト１９の照射範囲ＬＤ２は前向きの比較的狭い範囲を照射する状態となるのであり、左のライト１９のバルブ１９ａの光があまり拡散しないことによって、左のライト１９の照射範囲ＬＤ２は比較的明るいものとなる。   In the left light 18, the reflector 18b is configured to reflect the light of the bulb 18a diagonally forward to the left and right, and to reflect obliquely forward and downward. In the left light 19, the reflector 19b forwards the light of the bulb 19a forward. It is configured to reflect. As a result, in the state where the cutting unit 2 is positioned on the ground, the irradiation range LD1 of the left light 18 and the irradiation range LD2 of the left light 19 are in a state as shown in FIGS. Yes, the divider 10 is illuminated by the left light 18. In this case, the irradiation range LD2 of the left light 19 is in a state of irradiating a relatively narrow forward range, and the light of the bulb 19a of the left light 19 does not diffuse so much that the irradiation range of the left light 19 LD2 is relatively bright.

図５（ａ）に示すように、刈取部２を地面に位置させている状態において、右及び左のライト１８，１９の照射範囲ＲＤ１，ＲＤ２，ＬＤ１，ＬＤ２は側面視で斜め前方下方に向いている。図５（ｂ）に示すように、刈取部２を上限位置まで上昇駆動すると、右及び左のライト１８，１９の照射範囲ＲＤ１，ＲＤ２，ＬＤ１，ＬＤ２は側面視で略前方を向く状態となる。   As shown in FIG. 5A, in a state where the cutting unit 2 is positioned on the ground, the irradiation ranges RD1, RD2, LD1, and LD2 of the right and left lights 18, 19 are directed obliquely forward and downward in a side view. ing. As shown in FIG. 5B, when the cutting unit 2 is driven up to the upper limit position, the irradiation ranges RD1, RD2, LD1, and LD2 of the right and left lights 18 and 19 are in a state of facing substantially forward in a side view. .

図４に示すように、運転部３にライトスイッチ２１が備えられている。ライトスイッチ２１をＯＮ２位置に操作すると、右及び左のライト１８，１９が点灯する。ライトスイッチ２１をＯＮ１位置に操作すると、右及び左のライト１８が点灯して、右及び左のライト１９が消灯する。ライトスイッチ２１をＯＦＦ位置に操作すると、右及び左のライト１８，１９が消灯する。   As shown in FIG. 4, the light switch 21 is provided in the operation unit 3. When the light switch 21 is operated to the ON2 position, the right and left lights 18, 19 are turned on. When the light switch 21 is operated to the ON1 position, the right and left lights 18 are turned on and the right and left lights 19 are turned off. When the light switch 21 is operated to the OFF position, the right and left lights 18, 19 are turned off.

コンバインでは例えば図２に示すように、刈取部２の運転部３とは反対側が未刈り側Ａ１（作物がまだ刈り取られていない側）となり、刈取部２の運転部３側が既刈り側Ａ２（作物が既に刈り取られた側）となる。この場合、デバイダ９，１０，１１は作物の株元付近に位置し作物よって隠れている状態で、運転部３からデバイダ９，１０，１１を目視できない状態である。これに対して、未刈り側Ａ１の作物における既刈り側Ａ２の端部の列Ｂ１の横外側にデバイダ８が位置しており、運転部３からデバイダ８を目視することができるのであり、未刈り側Ａ１の作物における既刈り側Ａ２の端部の列Ｂ１とデバイダ８との位置関係を目視しながら、運転部３の操縦者はコンバインの運転を行う。
この場合、右のライト１８により未刈り側Ａ１の作物における既刈り側Ａ２の端部の列Ｂ１が照射されるようになるので、未刈り側Ａ１の作物における既刈り側Ａ２の端部の列Ｂ１を目視しながらの運転が行い易くなる。 In the combine, for example, as shown in FIG. 2, the side opposite to the driving unit 3 of the cutting unit 2 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, since the right row 18 irradiates the row B1 of the end portion of the already-cutted side A2 in the crop of the uncutted side A1, the row of end portions of the already-cutted side A2 of the crop of the uncutted side A1. It becomes easy to perform the operation while viewing B1.

Right and left lights 18 and 19 and a cover 20 similar to those in [Best Mode for Carrying Out the Invention] are provided.

これにより、刈取部２を地面に位置させている状態において、右及び左のライト１８，１９の照射範囲ＲＤ１，ＲＤ２，ＬＤ１，ＬＤ２、中央のライト２２の照射範囲ＳＤは図９に示すような状態となる。刈取部２を地面に位置させている状態での右及び左のライト１８，１９の照射範囲ＲＤ１，ＲＤ２，ＬＤ１，ＬＤ２、中央のライト２２の照射範囲ＳＤ、並びに、刈取部２を上限位置まで上昇駆動した状態での右及び左のライト１８，１９の照射範囲ＲＤ１，ＲＤ２，ＬＤ１，ＬＤ２、中央のライト２２の照射範囲ＳＤは、図５（ａ）（ｂ）と同様となる。   Thus, in a state where the cutting unit 2 is positioned on the ground, the irradiation ranges RD1, RD2, LD1, LD2 of the right and left lights 18, 19 and the irradiation range SD of the central light 22 are as shown in FIG. It becomes a state.
