Harry Ferguson began his career in the tractor industry by selling Waterloo Boy tractors (later rebranded as Overtime) in Ireland and England during World War I. While collaborating with farmers to enhance the efficiency of their new tractors, he developed an improved system for attaching implements. This innovative approach, known as the "Ferguson System," eventually evolved into the three-point hitch, which became the industry standard for connecting implements to farm tractors. To showcase his new hitch design, Ferguson created the Ferguson Black tractor. This led to a partnership with David Brown to manufacture the Ferguson-Brown tractor, but that collaboration was short-lived. Ferguson then partnered with Henry Ford to produce tractors equipped with his hitch system; however, this agreement ended in 1947 amid a contentious lawsuit. Subsequently, Ferguson formed a partnership with the Standard Motor Company to create his own line of tractors. In 1953, Ferguson was acquired by Massey-Harris, and the Massey-Ferguson brand continues to be recognized today under AGCO.
