Iron Plow

By the fourth century BC at the least, the frame-plow was being officially promoted by government officials of China. Nowhere else in the world at this time were there plows to compare with the Chinese ones. The study, square frames, strong heavy, well-designed shares and the new moldboards were all factors well in advance of anywhere else. But perhaps of greater importance stil was  the use of an adjustable strut which precisely regulated the plowing depth by altering the distance between the blade and the beam.

When plow methods were introduced into Holland and England in the seventeenth century from China, they sparked the European agricultural revolution, and it is believed that European agricultural revolution brought up the Industrial Revolution. Thus we can say, Chinese played an importrant role in this.
