Rotary tillage components are the most commonly used tillage components of the micro tillage machine. The engine power drives the rotary tillage blade shaft to rotate through the transmission device; The rotary tillage cutter shaft is horizontally arranged, and a number of rotary tillage blades are arranged around the cutter shaft. The cutter shaft transmission has two forms: intermediate transmission and side transmission.

The power driven rotary tillage blade continuously cuts the soil, and throws the cut soil blocks backward to collide with the mud shield and the flat soil support plate, so that the soil can be further broken and then fall to the ground, so as to achieve the purpose of cutting, throwing, breaking and leveling the soil, and the soil reaction force in the cutting process drives the micro tillage machine forward.
