The J.I. Case Threshing Machine Company was founded in 1842 at Rochester, Wisconsin by Jerome Increase Case. Early products included portable steam engines, steam traction engines and threshers. By the end of the 19th century they were the largest manufacturer of portable and traction engines in the world. J.I. Case built his first tractor in 1892, an experimental prototype based around a traction engine frame with a horizontal two-cylinder opposed engine designed by William Patterson. Numerous technical problems led to the project being abandoned, and it was not until two decades later that Case returned to tractor design. The first production tractor was the huge 30-60hp model built in 1912. This was followed by the 20-40, also in 1912, and the smaller 12-25 model in 1913. Following the general trend at the time, a three-wheeled 10-20 model was also produced in 1915 which featured a four-cylinder vertical engine mounted crossways. This engine layout was subsequently used in a whole series of "cross-motor" tractors, which ranged from the diminutive 12-20 to the gigantic 40-72 model. In 1929 another new direction was taken, with the introduction of the Model L featuring a four-cylinder in-line engine. This design prevailed, and Case went on to become one of the most important tractor manufacturers of the 20th century. They also offered a full range of implements to accompany their tractors, and achieved great success in the field of construction machinery. Case are still going strong today as part of the massive CNH (Case New Holland) organization.
