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.
