PROBLEM TO BE SOLVED: To provide a combine harvester advantageous from the viewpoints of structure and weight and capable of performing a peripheral area harvesting as well as center area harvesting while stably traveling and easily avoiding tramp of grain culm.SOLUTION: A distance between tips of a first outer grass divider and a first inner grass divider is made larger than the distance between tips of a second outer grass divider and a second inner grass divider, and larger than the distance between tips of the first inner grass divider and the second inner grass divider. The tip position of the first outer grass divider almost coincides with the outer end 16a of a crawler belt 16 in lateral direction of a traveling body. The tip position of the second outer grass divider coincides with the outer end 16a of the crawler belt 16 in the lateral direction of the traveling body. A core metal 47 embedded in the crawler belt 16 and a grounding wheel 14 are positioned at a side deviated outside of the traveling body relative to the center position C2 of the crawler belt 16 in lateral direction of the belt.COPYRIGHT: (C)2011,JPO&INPIT【課題】回り刈り作業も中割り刈り作業も穀稈踏み付けを回避しやすくかつ安定的に走行しながら行なえるコンバインを、構造面及び重量面で有利に得る。【解決手段】第一外分草具と第一中分草具の先端どうしの間隔を、第二外分草具と第二中分草具の先端どうしの間隔、第一中分草具と第二中分草具の先端どうしの間隔よりも大にしてある。第一外分草具の先端の位置とクローラベルト16の外側端16aの位置とが、走行機体横方向でほぼ一致している。第二外分草具の先端の位置とクローラベルト16の外側端16aの位置とが、走行機体横方向で一致している。クローラベルト16に埋設してある芯金47及び接地転輪14が、クローラベルト16のベルト幅方向の中心位置C2よりも走行機体外方側に片寄った位置に備えられている。【選択図】図4
