PROBLEM TO BE SOLVED: To provide a combine harvester that prevents the disturbance of a flow of waste straw, etc., guided and unloaded from a waste straw treatment part to the outside by an air exhaust from an engine. SOLUTION: The combine harvester is equipped with an exhaust gas pipe 30 for guiding an exhaust gas to the rear outside of a machine body 2, the waste straw treatment part 82 for treating waste straws at the rear of the exhaust gas pipe 30 and cut straw guide plates 83 which is arranged at the lower part of the waste straw treatment part 82, guides the treated straws to a right lower part and unloads them to the outside. The discharge port 30a of the exhaust gas pipe 30 is disposed at the leftmost side of an extension part in which the cut straw guide plate 83a positioned at the left part on the rear view among the cut straw guide plates 83 is extended downward and a blocking plate 32 is installed between the discharge port 30a and the cut straw guide plate 83 so that the blocking plate overlaps the discharge port 30a on the rear view. When a space part is arranged between the discharge port 30a and the blocking plate 32, the exhaust gas is diffused in the space part and an exhaust pressure by an exhaust from the engine 21 is not prevented. The whole discharge port 30a may overlap the blocking plate 32 on the rear view. COPYRIGHT: (C)2008,JPO&INPIT
