PROBLEM TO BE SOLVED: To easily set an inclination angle for automatic control in a combine harvester that is equipped with a pair of right and left traveling part lifting and lowering apparatuses for independently lifting and lowering right and left traveling apparatuses relative to a traveling machine body and adjusts the inclination of the traveling machine body, in the right and left directions. SOLUTION: A manual operation member 470 selectively takes a rise operation position D2 for lifting the traveling machine body 2, a fall operation position D1 for lowering the traveling machine body 2, a left side inclination position D3 for tilting the traveling machine body 2 to the left side; a right side inclination position D4 for tiling the traveling machine body 2 to the right side and a fifth operation position D5 different from the four operation positions. A controller 400 changes a fixed set angle to a horizontal angle, when the manual operation member 470 is operated to the fifth operation position D5, in an automatic control mode practice for automatically controlling the right and left inclination angle of the traveling machine body 2 so as to have the fixed set angle and in setting an angle, other than a horizontal angle as the set angle.
