<p>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.SOLUTION: A combine-harvester comprises: a stepless speed variator (10) which changes rotation of an engine (62); 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 mode switch (6B) which switches between a reaping/threshing mode and a manual threshing mode; a stop switch (6D); a controller (85) in which the engine (62) and the stepless speed variator (10) are automatically stopped, the threshing cylinder clutch (74) is cut off, and then the threshing cylinder brake (75) is activated and an actuator (54) is activated to automatically unlock an upper cover (50D) when the stop switch (6D) is operated in the manual threshing mode, and in which the engine (62) is automatically stopped while keeping the upper cover (50D) locked when the stop switch (6D) is operated in the reaping/threshing mode.</p> |
