1. Use of automatic profile floating cutter to ensure lowest harvesting height and adapt to the different landform.

2. Rasp-bar cylinder and spike tooth cylinder to gain much better threshing effect.

3. Use of re-threshing device obtains low loss rate and high cleanliness.

4. To higher purity and loss rate,adopt double louver sieves with adjustable opening.

5. Reclaim stem and skin separately, be used for feed, more systematic.

6. To control the loss rate effectively with the centrifugal fan and changeable wind speed.
