PROBLEM TO BE SOLVED: To provide a combine-harvester which can prevent grain and waste straw etc. from scattering outside of a machine caused by malfunction of a stop switch, and in which debris on a feed chain can be easily removed.SOLUTION: A combine-harvester comprises: a stepless speed variator (10) which changes rotation of an engine (62) to drive a feed chain (12B); a threshing cylinder clutch (74) which cuts off power to a threshing cylinder shaft (55A); a threshing cylinder brake (75) which is arranged in a transmission downstream side of the threshing cylinder clutch (74); a sensor (55S) which detects rotation of the threshing cylinder shaft (55A); and a controller (85) which stops, when the stop switch (6D) is operated, the engine (62) and rotation of the stepless speed variator (10), cuts off the threshing cylinder clutch (74), and activates the threshing cylinder brake (75), and then inactivates, when the sensor (55S) detects a rotation-stoppage of the threshing cylinder shaft (55A), the threshing cylinder brake (75). |
