Oliver Tractors: Models, Parts, and Specifications

The Oliver tractor remains a revered name among vintage agricultural equipment enthusiasts and working farmers alike. With a rich legacy spanning more than a century, the Oliver Corporation was instrumental in shaping the North American tractor industry, particularly during the mid-20th century. Known for their robust engineering, powerful engines, and innovative designs, Oliver tractor models such as the 1950 Oliver tractor, 1650 Oliver tractor, 1955 Oliver tractor, 1850 Oliver tractor, and 1550 Oliver tractor have stood the test of time.

Today, Oliver tractors continue to be used, restored, and celebrated across the United States and beyond. This article explores the company’s history, its most iconic models, how to find Oliver tractor parts, and the importance of resources like the Oliver tractor parts catalog for restoration and maintenance.

The History of the Oliver Tractor

The story of the Oliver tractor begins with the Oliver Chilled Plow Works, founded in 1855 in South Bend, Indiana. The company originally manufactured plows, but by the early 20th century, it transitioned into the broader agricultural machinery sector. The actual production of tractors began in earnest after the formation of the Oliver Farm Equipment Company in 1929—a merger of four companies, including Oliver Chilled Plow Works.

By the 1930s, Oliver was producing its own line of tractors, gaining a reputation for innovation, reliability, and solid engineering. Throughout the 1940s and 1950s, the company introduced several iconic tractor models that remain collector favorites today.

Oliver was acquired by the White Motor Corporation in the 1960s, and by the early 1970s, the Oliver name was eventually phased out, replaced by the White brand. However, the Oliver legacy lives on in the form of thousands of tractors still in operation and a dedicated collector community committed to restoration and preservation.
