The agricultural revolution brought about a change in tools. The agricultural revolution was a period of time in the 1800s where agricultural production increased dramatically as new farm machines were invented and used. During this time period, people were becoming interested in technology and modernization. This occurred in areas such as business and farming. As our population grew, especially in the cities, more food was needed. The old hand tools wouldn't be sufficient to meet the growing demand for food and other crops. As a result, many new inventions were made to help farmers. For example, the plow was invented. This made it easier to turn over the sod for planting. Eventually steel plows replaced wooden plows. Seed drills were developed to help with the planting of seeds. This was especially helpful in the Great Plains where seeds had to be planted deep in the earth to reach the water table. Reapers were invented which cut the grain and tied it into bundles. The cotton gin totally changed farming in the South. The cotton gin helped make cotton the main southern export by 1860. This machine separated the seeds from the cotton. To meet the growing demand for crops, farming changed greatly. Inventions helped increase crop output. This would potentially increase profits of farmers while satisfying the growing demand for food and other crops.
