Rotary-tiller is a tilling machine that is complete with tractor. It has been widely used because of its strong soil crushing ability and flat surface after ploughing. At the same time, it can cut up the root stubble buried under the ground to facilitate the seeder operation and provide a good seed bed for later sowing.

It can be divided into three types: horizontal axis, vertical axis and oblique axis. Proper use and adjustment of rotary tiller is important to maintain its good technical condition and ensure the quality of cultivation.

Rotary-tiller can break down the bottom of the plough, restore the soil surface structure, improve the soil moisture storage capacity, eliminate some weeds, reduce diseases and pests, level the surface and improve the agricultural mechanization operation standard.
