、分草体6と前記刈刃9との間の距離を短くする。The engagement hole 41 is formed in a straight line, and the engagement protrusion C of the rotating arm 39 moves in an arc centered on the front and rear frame ends, so when the engagement protrusion C moves upward within the engagement hole 41, the engagement The protrusion pulls the guide mallet backward, and each pulling device 7 rotates the center part of the upper horizontal transmission pipe 3 to rotate backward, thereby shortening the distance between the weeding body 6 and the cutting blade 9. do.
また、引起装置7と引起装置7の間にある分草体6は、
該分草体6の回動アーム(9)の基部が前側横フレーム
羽に固定されているから、前記前側横フレーム羽の回転
により回動アーム(9)を介して上方回動する。In addition, the weeding body 6 between the lifting devices 7 is
Since the base of the rotating arm (9) of the weeding body 6 is fixed to the front horizontal frame wing, the grass divider 6 is rotated upward via the rotating arm (9) by rotation of the front horizontal frame wing.
したがって、刈刃9に対して分草体6を出入装置36に
より後辺させた分、刈刃9は畦近傍に接近することが可
能となって、畦際の刈残しを少なくさせる。Therefore, since the weed cutting body 6 is moved to the rear of the cutting blade 9 by the inlet/output device 36, the cutting blade 9 can approach the vicinity of the ridge, thereby reducing the amount left uncut at the edge of the ridge.
この場合、前記回動アームおは各引起装R7の後方に設

せた分、刈刃9は畦近傍に接近させることが可能となっ
て、畦際の刈残しが少なくなるという効果を奏する。However, the present invention includes a grass cutting body 6 provided at the forefront, a plurality of pulling devices 7 provided behind the grass cutting body 6 for pulling up the grass culms, and a plurality of pulling devices 7 provided at the rear of the grass cutting body 6. In a combine harvester having a cutting blade 9 for cutting the root part of the culm raised by a device 7, the cutting blade 9 cannot change its front and back position freely, and the weeding body 6 can change its front and back position together with the lower part of the pulling device 7. Since the cutting blade 9 is used as the reaping part of a combine harvester, the cutting blade 9 cannot be changed in its forward or backward position, but the weeding body 6 can be freely changed in its forward or backward position along with the lower part of the pulling device 7, so that the cutting blade 9 cannot be changed in its forward or backward position. Since the cutting blade 9 is moved back toward the cutting blade 9 side (rear side), the cutting blade 9 can be brought closer to the ridge, which has the effect of reducing the amount of uncut material at the edge of the ridge.
