The advantages of a disc plow include low tillage resistance, easy breakage and blockage of soil blocks after tillage, compact overall structure, light weight, no need for frequent grinding and replacement of blades, low maintenance costs, no formation of solid trench bottoms, and suitability for sticky, dry, hard, stony, and multiple soil.

A disc plow is an agricultural machinery mainly used for tilling land, especially for turning, breaking and covering crop residues. The core of a disc plow consists of multiple circular plow discs mounted on a shaft, which are typically curved and adjustable in angle. The following are the functions and benefits of a disc plow:

Flipping soil: The disc plow cuts into the soil through the plow disc, flipping the surface soil and causing the bottom soil to flip up. This helps improve soil structure and create a favorable growth environment for crop cultivation.

Crushing soil: The disc plow can not only flip the soil, but also break it into smaller particles, which is beneficial for the contact between seeds and soil, promoting germination and root growth.

Weeding: During the cultivation process, a disc plow can effectively cut and cover weeds, reducing their competition for crops.

Covering crop residues: A disc plow can plow crop residues (such as straw) into the soil, promoting their decay and conversion into organic matter, and increasing soil fertility.

Breaking the compacted layer: A disc plow can break the compacted layer on the surface of cultivated land, which helps improve soil permeability and water permeability.
