The rotary tiller is a tillage machinery that works in conjunction with a tractor to complete plowing and harrowing operations. It has a strong ability to break up soil, achieving fine and even soil texture, and a level surface suitable for dryland sowing or paddy field planting. It helps to save time, improve work efficiency, and make full use of the power of the tractor. It can break up the plow layer, restore the soil structure, improve soil water retention capacity, eliminate some weeds, reduce pests and diseases, level the ground, and improve the standard of agricultural mechanization operations.
