PROBLEM TO BE SOLVED: To enable positioning while moving at low speed in a set time within a possible range of bag-taking and enable fast movement outside the range when discharging grains with a discharge auger.SOLUTION: A combine-harvester 1 comprises a discharge auger 32 consisting of a grain tank 17 for storing grains on a traveling device 2, a horizontally swingable vertical discharge auger 32a for discharging grains, and a vertically rotatable horizontal discharge auger 32b. The combine-harvester includes: turning-driving means which turns and drives the vertical discharge auger 32a; vertical driving means which vertically drives the horizontal discharge auger 32b; position detection means for the vertical discharge auger 32a and the horizontal discharge auger 32b; and operation means and control means 60 for operating the turning-driving means and the vertical driving means. When the vertical discharge auger 32a and the horizontal discharge auger 32b are located within a predetermined bag-taking possible range, the control means 60 allows an actuator 37 for ascent/descent and an actuator 35 for turning to drive at low speed within a prescribed time from the operation start of the operation means. |
