A disc harrow is an agricultural implement used for soil tillage and preparation, designed to break up and aerate the soil. It consists of a series of sharp, round discs mounted on a frame, which are arranged at specific angles to cut through the ground. As the harrow is pulled by a tractor, the discs penetrate the soil, chopping up clumps, and mixing in organic matter. This process helps improve soil structure, enhances seedbed preparation, and promotes better water infiltration. Disc harrows are versatile and can be used in various farming practices, including primary tillage and secondary tillage. They are particularly effective in managing heavy residue and preparing fields for planting, ultimately contributing to higher crop yields and healthier soil.
