A traction engine is a steam-powered tractor used to move heavy loads on roads, plough ground or to provide power at a chosen location. The name derives from the Latin tractus, meaning 'drawn', since the prime function of any traction engine is to draw a load behind it. They are sometimes called road locomotives to distinguish them from railway locomotives – that is, steam engines that run on rails.

In the late 19th century, Case was one of America's largest builders of steam engines, producing self-propelled portable engines, traction engines and steam tractors. It was a major producer of threshing machines and other harvesting equipment. The company also produced various machinery for the U.S. military. In the 20th century, Case was among the ten largest builders of farm tractors for many years. In the 1950s its construction equipment line became its primary focus, with agricultural business second.

The company started with a return flue design and later adapted the undermount style, including a bulldog design on the smokebox door. Their design was well received by farmers in central Illinois. They expanded their market nationwide and overseas until the 1920s, when they failed to innovate and the company faltered. They manufactured trucks for a period of time, and then automobiles. until they finally succumbed to an agricultural crisis and the Depression.

The National Threshers Association (NTA) is a non-profit group of enthusiasts who are interested in steam-powered traction engines - also known as "steam tractors", "steam traction engines" or simply "steam engines" - as well as related equipment. The group's premier event is its annual reunion/show, which features live exhibits of antique steam engines and gas-powered machinery from throughout the United States and Canada. Dating back to 1944, the annual show is recognized as the oldest event of its type in the United States.
