Simple and convenient and high in working efficiency / More adaptable to reaping of higher-yield crops.

1. Adoption of a combinative structure mechanism of a stepless speed regulator and a special-purpose gear box and the hydraulic booster steering, which is simple and convenient and high in working efficiency.

2. Adoption of a double-layer cutting device, which is small in feeding load, thus making it more adaptable to the requirement for reaping of higher-yield crops.

3. Adoption of hydraulically lifted reel, which is highly efficient in reaping collapsed crops.

4. A combinative mechanism is adopted in the threshing, sieving and cleaning unit, which includes a combinative axial-flow roller, a grid concave board, a blowing/suction bidirectional fan and a compound cleaning device consisting of a vibration sieve and a dual-processor, which is small in grain-loss and high in cleaning efficiency.

5. There are some patent technologies incorporated, such as the angle of the guide-plate of threshing top-cover is linkaged and adjustable, a new compound radiator water-tank and a grain-loading turnover plate hitching mechanism.

6. Special devices are provided as required by customers, such as an operators cab, an unloading type grain tank and a hydraulic steering devices.
