New Reproduction Ferguson System Owners and Mechanics Operation and Care Manual. This Manual shows how to get the most out of your Ford Tractor equipped with the Ferguson System Hitch. This manual was originally issued in 1946 and is meant for 1939, 1940, 1941, 1942, 1946, & 1947 Ford-Ferguson 2N/9N tractors; and would also be useful for 1948, 1949, 1950, 1951, & 1952 Ford 8N Tractors, and 1953, 1954, & 1955 Ford NAA tractors. Very informative and useful tool for the Ford Tractor Owner that will display well [see photos].
