PROBLEM TO BE SOLVED: To provide a general purpose combine harvester which can reversely drive a harvesting portion such as a feeder, and can smoothly reversely drive the feeder in a simple structure without excessively reducing the rotation speed of an engine.SOLUTION: In a general purpose combine harvester, a harvesting portion 3 having a feeder 9 and a reel 14 is connected to a travel machine frame 2, a feeder-driving shaft 69 is provided for driving the feeder 9 in a normal rotation to convey the grain stalks harvested with the harvesting portion 3 to the travel machine frame 2 side, and a reverse rotation transmission member 107 is provided for driving the feeder 9 in a reverse rotation. The general purpose combine harvester is provided with the reverse rotation transmission member 107 rotatably on the feeder-driving shaft 69, a reverse rotation driving shaft 97 for reversely driving the feeder 9 on the feeder 9 side, and a speed reducer 96 for reducing the power of the reverse rotation transmission member 107 and transmitting the power to the reverse rotation driving shaft 97.COPYRIGHT: (C)2013,JPO&INPIT【課題】フィーダ等の刈取部を逆転駆動させることができる汎用コンバインにおいて、簡略な構成により、エンジンの回転数を必要以上に落とすことなくスムーズにフィーダを逆転駆動させることができる汎用コンバインを提供することを課題としている。【解決手段】フィーダ9及びリール14を有する刈取部3を走行機体2に連結し、刈取部3で刈取られた穀稈が走行機体2側に搬送されるようにフィーダ9を正転駆動させるフィーダ駆動軸69を設けるとともに、該フィーダ9を逆転駆動させるように回転する逆転用伝動部材107を設けた汎用コンバインであって、前記逆転用伝動部材107をフィーダ駆動軸69に回転自在に設けるとともに、前記フィーダ9を逆転駆動させる逆転駆動軸97を該フィーダ9側に設け、逆転用伝動部材107の動力を減速して逆転駆動軸97に伝動する減速機構96を備えた。【選択図】図4
