Zusammenfassung:	PURPOSE: To enable the obtaining of an adequate amount of the grading wind not only in a low speed region but also in a high speed region of a vehicle in a combine provided with a wind amount-controlling means for automatically controlling the rotative speed of a winnower by synchronizing with the vehicle speed. CONSTITUTION: This grading wind-supplying apparatus for a combine is provided with the following members: an auxiliary blower 28 for increasing the amount of grading wind from a winnow fan 17 located in a manner freely controlling the amount of the grading wind; a sensor 26 for detecting the amount of the treated matter; and an automatic device 31 for increasing the amount of the grading wind by actuating the auxiliary blower 28 based on the information from the sensor 26 when the amount of the treated matter exceeds a specified value.
