PROBLEM TO BE SOLVED: To provide a combine harvester capable of performing cleaning treatment of an exhaust gas and requiring no supply of urea water during harvesting work.
SOLUTION: The combine harvester is equipped with a diesel engine for driving a threshing apparatus, a threshing clutch 93 for putting on and off power transmission to the threshing apparatus and a threshing drive circuit 118 for inhibiting a switch-on action of the threshing clutch 93. In addition, the combine harvester is equipped with a NOx cleaning means for accelerating reduction of NOx in an exhaust gas from the diesel engine, a urea water tank for storing urea water added to the exhaust gas and a urea water sensor 113 for detecting the amount of urea water in the urea water tank. When the amount of urea water in the urea water tank is equal to or less than a predetermined amount, the threshing clutch 93 is constructed to be kept in a power-off state by the threshing drive circuit 118.
