A counter shaft is erected in the power transmission room extending from the threshing wind selection unit, and the input side is integrated with the counter case and installed inside the mounted threshing machine. It has become smoother, making loading and unloading and assembling easier.

Since the bottom of the transmission chamber formed by the extended frame is made an open base and a dustproof plate is hung down on the front to surround the transmission chamber, a gap is generated due to the elevation of the cutting unit. It was difficult to prevent intrusion and accumulation of dust.

Since the power transmission chamber is extended to a position parallel to the cutting pivot, and a fulcrum shaft for raising and lowering the cutting section is provided, the feed chamber is structured so as to hold the feed house. The rolling surface of the mowing part has been reduced due to the holding structure with an enlarged moving surface.
