PROBLEM TO BE SOLVED: To provide a combine which performs automatic reproduction control of a capture filter by means of reproduction means and prevents high temperature exhaust gas to be blown to a peripheral straw.SOLUTION: The combine includes: a capture filter 14 capturing fine solid matters contained in exhaust gas clogging detection means 32 detecting clogging of the capture filter 14 reproduction means removing fine solid matters captured by the capture filter 14 by means of high temperature exhaust gas switch means 29, 33 performing switch to a manual feed threshing mode and a control unit 19 performing automatic reproduction control for automatically reproducing the capture filter 14 through the reproduction means subject to at least detection of clogging of the capture filter 14. While the combine is switched to the manual feed threshing mode, performance of the automatic reproduction control is restricted.SELECTED DRAWING: Figure 6
