摘要：

PROBLEM TO BE SOLVED: To provide a combine harvester easily preventing the accumulation of grasses and straws on an exhaust pipe 33 while preventing the movement of exhaust gas of an engine 20 toward an operator.

SOLUTION: The combine harvester comprises a traveling machine body 1 equipped with the engine 20, right and left traveling crawlers 2 for supporting the traveling machine body 1, an operation part 10 having a control handle 11 and a drivers seat 12, a reaper 3 for reaping unreaped grain culms in a field, and a thresher 5 for threshing the reaped grain culms. The thresher 5 is equipped with a separation fan 241 for feeding a separation wind to a tailings conveyor 232 for taking out tailings such as grains with rachis-branches. In the combine harvester, an outside air introduction duct 41 for communication with the outside air suction side of the separation fan 241 is installed. The separation wind suction side of the separation fan 241 communicates with the top surface side of the exhaust pipe 33 of the engine 20 via the outside air introduction duct 41.
