PROBLEM TO BE SOLVED: To provide a combine harvester that hardly loses a weight balance in the right and left directions of a machine body and increases direct advance traveling performances of the machine body, by arranging two motors in a divide manner in the right and left directions relatively to the center of gravity position of the machine body as a whole.SOLUTION: The combine harvester comprises: a threshing apparatus (4) equipped with a feed chain (25) and a grain storage apparatus (3) equipped with a grain unloading apparatus (23) at the upper side of a traveling apparatus (1) and a reaping apparatus (5) installed ahead of the threshing apparatus (4). The combine harvester is further equipped with the first motor (6) for driving the traveling apparatus (1), the threshing apparatus (4) and the grain unloading apparatus (23) and the second motor (68) for driving the reaping apparatus (5) and the feed chain (25), independently from the first motor (6). The first motor (6) and the second motor (68) are disposed in a divided manner, in the right and left directions relative to the center of gravity position of the whole machine body.COPYRIGHT: (C)2008,JPO&INPIT【課題】2つの原動機を機体全体の重心位置に対して左右方向に振り分けて配置することにより、機体の左右方向の重量バランスを崩れにくいものとして、機体の直進走行性能を高める。【解決手段】走行装置(1)の上側にフィードチェン(25)を備えた脱穀装置(4)と穀粒排出装置(23)を備えた穀粒貯留装置(3)とを設け、脱穀装置(4)の前側に刈取装置(5)を設けたコンバインにおいて、走行装置(1)と脱穀装置(4)と穀粒排出装置(23)とを駆動する第1原動機(6)を設けると共に、第1原動機(6)とは独立して刈取装置(5)とフィードチェン(25)とを駆動する第2原動機(68)を設ける。そして、第1原動機(6)と第2原動機(68)とを、機体全体の重心位置に対して左右方向に振り分けて配置する。【選択図】図1
