The Animal-Drawn Seed Plough (Lou Che) is a sowing implement driven by animals. Since it has three legs, it's also called "Three-legged Seed Plough". It's equipped with three opening shares. During the process of sowing, a cattle is made to pull the seed plough, when the plough legs will dig the earth, sow seeds on the leveled ground, cover the seeds, and compact the ground. In this way, all jobs can be done at the same time, saving both time and efforts while realizing the efficiency of "sowing 100 mu within one day".

Later the implement was introduced into Europe and became one of the causes to the breakout of Agricultural Revolution in Europe.
