A disc plough, often referred to as a disc plow or simply a plough, is a primary piece of agricultural equipment used for tillage and soil preparation in farming. It is designed to break up and turn over soil to prepare it for planting by cutting, loosening, and mixing the soil. Here’s how a disc plough typically works:

1. Disc Blades: A disc plough consists of a series of concave, circular metal discs that are mounted on a horizontal shaft. These discs are usually made of hardened steel and are designed to cut through the soil.
2. Mounting and Depth Adjustment: The disc plough is attached to a tractor or another suitable vehicle. The angle and depth of the discs can often be adjusted based on the specific requirements of the field and the depth to which you want to plough.
3. Field Operation: As the tractor moves forward, the spinning discs cut into the soil at a predetermined depth, typically ranging from a few inches to several inches, depending on the desired tillage depth.
4. Soil Turning: The discs cut into the soil, breaking it into smaller clumps and turning it over. This process helps to bury crop residues, weeds, and organic matter into the soil, which can improve soil fertility and structure.
5. Furrow Creation: Depending on the design of the disc plough, it may create furrows between the rows, which can be used for planting or seeding crops.
6. Residue Management: Disc ploughs can effectively manage crop residues, which can help reduce disease and pests in subsequent crops.
