COMBINE HARVESTER

PROBLEM TO BE SOLVED: To provide a combine harvester capable of accurately sorting processed material after threshing. SOLUTION: The combine harvester is provided with a waste straw quantity detection device 160 to detect quantity of waste straw, a processed material quantity detection device 163 to detect quantity of processed material on a chaff sieve 53, and a controller 12 to calculate a waste straw correction angle β based on a waste straw sensor angle B of the waste straw quantity detection device 160 and a sieve correction angle γ based on a sieve sensor angle C of the processed material quantity detection device 163, to control a chaff actuator 130 based on the waste straw correction angle β when the sieve sensor angle C of the processed material quantity detection device 163 is smaller than a threshold value Ct, and to control the chaff actuator 130 based on the waste straw correction angle β (β1) corresponding to a case where the sieve sensor angle C is equal to the threshold value Ct and based on the sieve correction angle γ when the sieve sensor angle C is equal to or larger than the threshold value Ct.
