arious types of tillage implements used in farming can be broadly categorized into several categories depending on the purpose of their use. Generally there are two types of such categories – primary and secondary. Equipment used in these categories are also known as primary tillage equipment and secondary tillage equipment. Primary Tillage Equipment Equipment that are used for loosening and opening the upper layer of the soil are known as primary tillage equipment and include different types of ploughs such as wooden ploughs, iron or inversion ploughs or special purpose ploughs. Secondary Tillage Equipment Once the primary tillage is done, farmers need to prepare the soil for making seedbed. To make a perfect seedbed soil should be in smooth form and clod free. Cultivators, harrows, planks, mould board plough and rollers are used as secondary tillage to give soil a smooth structure. Here we are going discussed about three types of plough and their work Disc Plough A disc plough cuts, lose and turn the soil using concave steel disc which turns the furrow slice to one side with a scoop action. The disc plough works perfectly in land where there is lots of fibrous growth of weeds. The discs easily cuts and incorporates the weeds. It is suitable to work in areas where soil is free from stones. It also chops and incorporates crop residues. Mould Board Plough A mould board plough is used to give soil the final structure to sow seeds once the initial ploughing is done. It turn the soil completely as the furrow slices are cut clean and inverted to one side ensuing in better pulverization. It uses wing-shaped large curved bottom attached to a frame that slice and invert the layers of soil leaving a rough soil surface. The mb plough has different ploughing benefits – 1) It digs deep into the earth 2) cuts a row 3) turns the earth 4) aerates the soil all at the same time. Reversible Mould Board Plough
A reversible mould-board plough turns the upper layer of the soil to the right or left side of direction or as required when making its rounds attached to a tractor. It includes two sets of curved bottoms attached to a frame on opposite sides using one side bottoms for one direction and the other side bottoms for the other direction in the returning round. Both the bottoms are mounted in such a way that they can be raised or lowered individually and can also be rotated along an axis. It is used in primary as well as secondary tilling process.
