PROBLEM TO BE SOLVED: To improve workability for discharging grains, the extension or contraction function of a discharging auger, and the like. SOLUTION: In this combine harvester, a discharging auger 18 for discharging grains in a grain tank 16 is disposed, and the cylindrical body of the discharging auger 18 for forming a grain-discharging port 20 is extended or contracted with an extending or contracting mechanism 29 to extend or contract the discharging auger 18. The spiraler 32 and spiraler shaft 33 of the discharging auger 18 are divided into plural sets, respectively, and a central shaft 18b on which the plural sets of the divided spiralers 32 and the divided spiraler shafts 33 are disposed in the connecting or disconnecting state is inserted in the cylindrical body 25. |
