PROBLEM TO BE SOLVED: To provide a combine-transmission structure capable of transmitting the power to a thresher and a clipper while preventing the concentration of a transmission load on a long-size shaft.SOLUTION: A combine-harvester comprises: a transmission case arranged at the front of a thresher a handling drum input shaft extending in the machine body widthwise direction while having the other side in the machine body widthwise direction protruding into said transmission case, so that rotation power is operation-transmitted to one side in the machine body widthwise direction from an engine a bevel gear mechanism housed in the transmission case such that the other side in the machine body widthwise direction of the handling drum input shaft is operatively transmitted to the front side of a handling drum shaft and an operative system transmission shaft extending in the machine body widthwise direction while the one side in the machine body widthwise direction is connected in a relatively non-rotatable manner on the other side in the machine body widthwise direction of the handling drum input shaft. The rotation power is transmitted to separation mechanisms in a cutting device and the thresher from the other side in the machine body widthwise direction of an operation system transmission shaft.SELECTED DRAWING: Figure 7
