how is an iron plough used?
Plough is used for loosening and turning of soil. A plough is made up of wood, and is drawn by a pair of bulls. It contains a strong iron strip, which is triangular in shape and is known as a ploughshare. The main part of this tool is made up of a long log of wood, which is known as a ploughshaft. At one end of the shaft, there is a handle while at the other end a beam is attached, which is placed on the neck of the bull. Nowadays, wooden ploughs have been replaced by iron ploughs.
