  Next, the structure of the auxiliary pulling device 70 for cutting the four strands will be described with reference to FIGS. 1 to 5, 8, 12, 12, 15, and 25. FIG. As shown in FIGS. 5, 12, and 25, three sets of auxiliary pulling devices 70 for raising the lying straw of the field are arranged at the center of the left and right sides, the left side, and the right side of the front side of the wheat straw pulling device 31. is doing. The auxiliary pulling device 70 includes an auxiliary pulling case 71 provided with a plurality of auxiliary pulling tines 71a for causing a fallen culm in the field, an auxiliary herbaceous body 71b disposed on the pulling start end side (lower end side) of the auxiliary pulling case 71, An auxiliary pulling drive case 71c that supports the pulling end side (upper end side) of the auxiliary pulling case 71 is provided.

  The rotational force of the pulling tine drive shaft 41a is transmitted to an auxiliary pulling tine chain (not shown) that supports a plurality of auxiliary pulling tines 71a at equal intervals via a bevel gear or the like in the auxiliary pulling drive case 71c. When the auxiliary pulling tine 71a of the auxiliary pulling case 71 is actuated, the fallen cereal of the field taken in between the auxiliary weeds 71b is pulled up by the auxiliary pulling tine 71a, and the pulling tine 42a of the pulling case 42 behind (See FIG. 5).

  As shown in FIG. 25, the left and right auxiliary pulling case 71 and the left auxiliary pulling case 71 arranged in front of the pulling case 42 are erected in parallel with the pulling case 42 in a front view. The right auxiliary pulling case 71 disposed in front of the pulling case 42 is tilted in the left-right direction. Further, the right light housing 83R is extended to the upper end side of the right side cover 82R within the right and left width of the right side cover 82R in front view. The inboard end edges of the right side cover 82R and the right light housing 83R are joined to the right end edge of the rightmost pulling case 42 substantially flush with each other.

  Further, the raising start end side (lower end side) of the right auxiliary raising case 71 projects outward from the right side surface of the right side cover 82R. The trailing end side (upper end side) of the auxiliary pulling case 71 protrudes from the upper inner edge of the right side cover 82R or the rightmost pulling case 42 on the left side of the right inner housing edge of the right light housing 83R. Has been. That is, among the plurality of auxiliary pulling devices 70, at least the rightmost auxiliary pulling device 70 is tilted in the left-right direction, and the light housing 83R is positioned on the outer side of the fuselage from the upper end side of the rightmost auxiliary pulling device 70. I am letting.

  As shown in FIGS. 12 and 25, the auxiliary pulling device 70 is provided to stand the fallen cereals in the field, and a plurality of auxiliary pulling devices 70 are arranged in front of the pulling case 42. Among them, at least the rightmost auxiliary pulling device 70 is tilted in the left-right direction, and the right light housing 83R is positioned on the outer side of the machine body from the upper end side of the rightmost auxiliary pulling device 70. Therefore, the front side of the rear right headlamp 81 is not shielded by the auxiliary pulling device 70 disposed on the side of the reaping device 3, and the light of the right headlamp 81 is applied to the lying cereal of the field. Can be effectively irradiated and night workability can be improved.
