A disc harrow is an agricultural implement used for secondary tillage. It is designed to break up and smooth the soil after primary tillage (such as plowing) in preparation for planting crops. Disc harrows consist of a series of concave cutting discs mounted on a common shaft. Here are key features and functions of a disc harrow:

1. Disc Arrangement:
   • Disc harrows have multiple concave cutting discs arranged in rows, typically mounted in a rectangular or staggered configuration. The discs can be evenly spaced or offset for better soil coverage.
2. Cutting Action:
   • The cutting discs of a disc harrow rotate as the implement is pulled through the field by a tractor. The rotating discs cut into the soil, breaking up clods, and smoothing the surface.
3. Depth Adjustment:
   • Many disc harrows have a depth control mechanism that allows the operator to adjust the working depth of the cutting discs. This feature is crucial for adapting to different soil conditions and types.
4. Spacing Adjustment:
   • Some disc harrows allow for the adjustment of disc spacing. This feature enables the farmer to customize the harrowing width based on the crop and field requirements.
5. Blade Sharpness:
   • The cutting discs are equipped with sharp blades or edges that efficiently cut through the soil. Regular maintenance, including blade sharpening, is essential for optimal performance.
