Tractors first emerged in the early 19th century when steam engines on wheels were used to help drive mechanical farm machinery using a flexible belt. The first portable steam engine used for agricultural purposes was invented by Richard Trevithick in 1812 and was known as the Barn Engine. Since then John Deere, International Harvester, and other manufacturers have made them a staple of farm operations. See if you can find your favorites in this 24″x30″ 1000 piece puzzle by Stephen M.
