動部周辺構造の簡略化を図ることを目的としている。Heretofore, in this type of combine, there has been already known a combine in which a mowing part is slidably moved in the horizontal direction. The purpose of moving the mowing part laterally is to move the mowing part to the left side (non-cutting ground side) when performing round cutting work with the uncut side to the left, and to set the distance between the uncut grain culm and the traveling crawler. So that the crawler does not push down uncut culms by mud, and set the cutting section on the right side when performing middle splitting work, etc. The point is that the right uncut culm is not depressed. SUMMARY OF THE INVENTION It is an object of the present invention to simplify a peripheral structure of a transmission section from a traveling body to a cutting section in a horizontal sliding device of a cutting section.
