What are the advantages of a disc plow?

The tillage resistance is small, the soil blocks after tillage are easy to break and not easy to clog, and the whole machine has a compact structure and light weight.
It can cut and tear the connected ground cover and branches on the ground and mix them into the soil. The disc knife can roll over obstacles to reduce damage to the machine and have low energy consumption.
The disc plow has a strong ability to cut grass roots and stubble, and is not easy to clog. It is mostly used for ploughing operations in complex farmlands such as weeds, upright stems, large soil resistance, and brick and stone fragments in the soil.
The disc plow is suitable for heavy, dry, stoney, and rooty soils; it does not need to be sharpened and replaced frequently, has low maintenance costs, and does not form a solid ditch bottom.
