The main occupation of the Harappan people was agriculture. The remains of different grains found in the Harappan sites make that clear. But it is not easy to reconstruct their agricultural technologies. For example, we are not sure if the Harappan people sowed the seeds in ploughed farms. The images found on the seals and clay sculptures show that they were familiar with bulls. From this, the archaeologists think that probably they used bulls to plough the fields.
At the sites in Kolistan (Pakitan) and Banwali (Haryana), clay models of ploughs were found. At Kalibengan in Rajasthan, the researchers v have found evidences of a ploughed field. In this field, there are two different rows of furrows. It shows they cultivated different crops.
Researchers also tried to find out the type of implements the Harappans used for harvesting. We are not sure if they used sickles with wooden handles or some metallic implements for cutting the crops.
