In addition, since the auger operation panel surface is close to the eye level of the operator, visibility is improved.

  In the conventional model, since the auger operation panels 60 and 62 are arranged on the left rear side of the operation seat 20, the operator faces the front of the combine so as to project the auger 15 in a direction different from the actual projecting direction of the auger 15. Since it was necessary to switch the auger operation panels 60 and 62, it was difficult to operate the auger 15. However, with the above configuration, the overhang direction of the auger 15 can be easily controlled. In addition, since the operation surfaces of the auger operation panels 60 and 62 are close to the eye level of the operator, the visibility is improved.
