A mould board is a crucial component of a plough used in agricultural operations. Its primary function is to cut through and turn over the soil, preparing it for planting. The mould board efficiently lifts, turns, and breaks the soil, helping to bury weeds and crop residues while improving aeration and drainage. Typically made from durable steel, mould boards are designed for long-lasting performance and come in different sizes and shapes to suit various soil conditions and ploughing needs.
