The terra-cotta plough of the Harappan civilization was found at Banawali. The Harappan civilization, also known as the Indus Valley civilization, was an ancient urban civilization that existed around 2600 to 1900 BCE in what is now modern-day Pakistan and northwest India. The civilization was known for its advanced urban planning, impressive architecture, and sophisticated drainage systems.

The terra-cotta plough was an important agricultural tool used by the Harappan people for ploughing and cultivating their fields. It was made of baked clay and had a simple design that consisted of a wooden shaft attached to a heavy blade. The plough allowed the Harappans to increase their agricultural productivity and support a large population.

The plough was discovered at Banawali, which is an archaeological site located in Haryana, India. Banawali is one of the many sites where artifacts and remains of the Harappan civilization have been found. The discovery of the terra-cotta plough at Banawali provides valuable insights into the agricultural practices and technology of the Harappan people.
