Although with the invention and application of modern tools, many traditional farming tools have gradually withdrawn from the stage of history, but the iron rake, as one of the necessary farm tools for farmers, is still in use today.
The harrow has a history of more than 1500 years in China.
In the Northern Wei Dynasty, Jia Sixie's "Qi Min Yao Shu" is called "Tie Tooth", and the operation of using this farm tool is called a harrow.
The Yuan "Wang Zhen Nong Book" records square rake, herringbone rake, lao (toothless rake woven with wicker) and chao (tian rake for paddy fields).
