Early tractors utilized custom methods for attaching implements. These methods varied by manufacturer and model, making it diffifult to interchange equipment.

The three-point hitch system was invented by Harry Ferguson and called the "Ferguson System". It consisted of three linkage points and hydraulics. It enabled the operator to simply back up to the implement, connect, and lift. The system was first used on the Ford 9N in 1939, the result of an informal agreement between Ferguson and Henry Ford. The system was also used on the 2N. Then, in 1947, Henry Ford II terminated the agreement.

The system was used on the new Ford 8N but without providing credit to Ferguson or paying royalties. Ferguson later settled a lawsuit against Ford.

As Ferguson's patents expired the system was standardized and adopted across the entire industry.
