PROBLEM TO BE SOLVED: To improve the working efficiency of a combine by making its movement as small in the vicinity of descended position of a reaping part conveying the cereal culms after the reaping in rear directional upper part, for reducing an inconvenience such that the reaping part thrusts into the surface of a field on its fine tuning. SOLUTION: This combine is provided by installing an ascending operation switch 20a and a descending operation switch 20b for performing the lifting up and down operation of the reaping part 4 on a steering lever 18 and a controlling device 17 for outputting an ascending output or a descending output for a prescribed time to an actuator 14 side for driving the lifting up and down of the reaping part 4, and regulating the descending output time on descending the reaping part 4 at a lower side position than the set position as a shorter time than the descending output time for descending the reaping part 4 at an upper side position than the set position.
