PROBLEM TO BE SOLVED: To provide a combine-harvester for making a free grain over rack easily recoverable thereby to improve a threshing efficiency.SOLUTION: A combine-harvester comprises: a thresher 50 equipped with a plurality of threshes 57 protruding outward of a radial direction, and a thresh 52 for driving rotationally in a handling chamber K, and a receiving net 53 disposed below the thresh 52； a feed chain 55 for clamping the root side of the grain culm W while positioning the ear tip side of the grain culm W in the handling chamber K, thereby to convey the grain culm W from the front side to the rear side of a thresher 50. Of the handling teeth 57, rear end side handling teeth 57b disposed at the rear side of the thresh 52 protrudes longer than the other handling teeth 57a positioned on the front side of the handling teeth 57b.SELECTED DRAWING: Figure 3【課題】ささり穀粒を回収し易くして、脱穀効率の向上を図る。【解決手段】径方向外方に向けて突出する複数の扱歯５７が設けられ、扱室Ｋ内で回転駆動する扱胴５２、及び、扱胴５２の下方に設けられた受網５３を有する脱穀装置５０と、刈取穀稈Ｗの穂先側を扱室Ｋ内に位置させながら刈取穀稈Ｗの株元側を挟持して、刈取穀稈Ｗを脱穀装置５０の前部側から後部側に向けて搬送するフィードチェーン５５と、が備えられ、複数の扱歯５７のうち、扱胴５２の後端部に設けられた後端部側扱歯５７ｂは、後端部側扱歯５７ｂよりも前側に位置する他の扱歯５７ａより突出長さが長い。【選択図】図３
