前記切換伝動ケース12内に設けたシフター17fを、図4、及び図7で示すように、この切換伝動ケース12の外部より移動操作可能に設け、又、シフター17fの位置決め用のワイヤスプリング18b、及びワイヤ取付板12bを、このケース12の外側で上方に設けている。
Thereby, the switching transmission case 12 can be miniaturized. In addition, the configuration is simplified and the cost is reduced. The overall balance of the reaping device 4 is improved.
As shown in FIGS. 4 and 7, the shifter 17f provided in the switching transmission case 12 is provided so as to be movable from the outside of the switching transmission case 12, and a wire spring 18b for positioning the shifter 17f. In addition, the wire attachment plate 12b is provided on the outside of the case 12 at the upper side.

これにより、前記ワイヤ18cの屈曲防止、及び干渉防止ができる。
前記引起装置8の引起ケース8c内には、図15〜図17で示すように、引起チェン8aを張設し、この引起チェン8aには、所定間隔で引起ラグ8bを装着している。この各引起ラグ8bは、一方側の引起し作用側は、引起ケース8c内から突出して穀稈を引起し、他方側は、該引起ケース8c内へ収納状態になって回転駆動する構成である。
Thereby, it is possible to prevent the wire 18c from being bent and to prevent interference.
As shown in FIGS. 15 to 17, a pulling chain 8a is stretched in the pulling case 8c of the pulling device 8, and pulling lugs 8b are attached to the pulling chain 8a at predetermined intervals. Each pulling lug 8b has a structure in which one pulling action side protrudes from the pulling case 8c to raise the cereal and the other side is rotationally driven while being housed in the pulling case 8c. .

前記左右両側に配設する各引起装置8の各引起ケース8cの左右両側の上方部には、図15〜図17で示すように、引起ラグ8bの回転外周軌跡に沿うように、外側へ突出する突出部8eを形成した外カバー8dを設けている。又、この外カバー8dの突出部8eの内側面には、引起ラグ8bの先端部が当接しないように、該突出部8eを形成して設け、更に、左右両側のこの突出部8e、8eには、各前照灯4bを設けている。左側の該外カバー8dの外端部と、分草体7aの外側とは、略同じ位置(イ)へ設けている。又、右側の該外カバー8dの外端部は、分草体7aの外端部より、所定寸法(ロ)位置内側へ設けている。   As shown in FIGS. 15 to 17, as shown in FIGS. 15 to 17, the upper portions of the pulling cases 8 c of the pulling devices 8 disposed on the left and right sides protrude outward so as to follow the rotation outer peripheral locus of the pulling lugs 8 b. An outer cover 8d in which a protruding portion 8e is formed is provided. Further, the protruding portion 8e is formed on the inner side surface of the protruding portion 8e of the outer cover 8d so that the tip end portion of the pulling lug 8b does not come into contact with the protruding portion 8e. Is provided with each headlamp 4b. The outer end portion of the left outer cover 8d and the outer side of the weeding body 7a are provided at substantially the same position (A). Further, the outer end portion of the outer cover 8d on the right side is provided inward of a predetermined dimension (b) position from the outer end portion of the weed body 7a.

これにより、騒音、及び振動の防止が可能である。引起ラグ8bの収納音防止用の部材が不要となり、コスト低減になる。前照灯4bの装着により、夜間作業が容易になる。
図18で示すように、副変速レバー21aと、刈取クラッチテンションアーム26aとをリンクプレート27で接続し、このリンクプレート27に設けた長孔27a部と、この刈取クラッチテンションアーム26aとは、ピン27bで接続した構成である。該刈取クラッチテンションアーム26aの先端部には、テンションプーリ26bを回転自在に軸支している。このテンションプーリ26bにより、ベルト28を「入」−「切」する構成である。
As a result, noise and vibration can be prevented. A member for preventing the stored sound of the pulling lug 8b is not necessary, and the cost is reduced. The night work is facilitated by mounting the headlamp 4b.
As shown in FIG. 18, the auxiliary transmission lever 21 a and the cutting clutch tension arm 26 a are connected by a link plate 27, and a long hole 27 a portion provided in the link plate 27 and the cutting clutch tension arm 26 a are connected to a pin. 27b is connected. A tension pulley 26b is rotatably supported at the tip of the cutting clutch tension arm 26a. With this tension pulley 26b, the belt 28 is "on"-"off".

又、前記刈取クラッチテンションアーム26aと、刈脱レバー21bとは、刈脱ワイヤ28aと、スプリング28aとにより接続している。副変速レバー21aを走行速の「高速」へ操作したときには、この刈取クラッチテンションアーム26aを介してテンションプーリ26bを「切」に作動する構成である。   The mowing clutch tension arm 26a and the mowing lever 21b are connected by a mowing wire 28a and a spring 28a. When the auxiliary transmission lever 21a is operated to the "high speed" of the traveling speed, the tension pulley 26b is actuated to "off" via the cutting clutch tension arm 26a.

これにより、走行速「高速」での穀稈の刈取作業を防止できる。又、安価な構成になる。更に、刈取作業開始時に前記刈脱レバー21bを再度「入り」に操作する必要がなくなった。   As a result, it is possible to prevent the grain reaping work at the traveling speed “high speed”. Moreover, it becomes an inexpensive structure. Furthermore, it is not necessary to operate the cutting / removing lever 21b again to “enter” at the start of the cutting operation.
