What tools did the Harappans use for farming?

The Harappans used simple yet effective tools for farming, made primarily of wood and stone. They employed plows to till the land, and evidence suggests these plows were often drawn by oxen. Harappans also used sickles with wooden handles and stone blades for harvesting crops. Their tools were designed to meet the needs of the fertile Indus plains, enabling them to grow crops like wheat, barley, and cotton. These tools highlight their ingenuity in agricultural practices and their ability to adapt to the environment.
