Massey Ferguson Tractors

Massey-Harris's early tractor models included the 20 horsepower Massey-Harris GP 15/22 (1930–36), 25 horsepower Massey-Harris Pacemaker (1936–39), 35 horsepower Model 101 (1938–42), Massey-Harris Pony, Model 20, Model 81, and Model 744. The final generation of Massey-Harris tractors, introduced immediately after World War II, included the 25 horsepower M-H 22 series, the 35 horsepower M-H 33 series, the 45 horsepower M-H 44 series and the 55 horsepower M-H 55 series. These tractors commonly known as the triple series were mechanically similar to their predecessors but featured new styling which included a slightly different hood design, chrome trim on the grill and hood, and a different color scheme. They were also available with power steering, live PTO and hydraulics. The Massey Harris triple series tractors remained in production until 1958.

Massey began experimenting with oil engines about 1910, with engines such as the Bulldog. However, success came only later in the 1920s with the Wallis line of tractors which was purchased by the firm. Massey Harris also produced one of the world's first four-wheel drive tractors. Hart Massey's sons Charles, Walter, Chester and Fred became closely involved in the business and eventually took over its operations. In 1966, Massey purchased 32% of the Spanish tractor and auto company Ebro, or Motor Iberica. Ebro had previously built Ford tractors under license, but now began building models for Massey, and Massey models under license. In 1973 Massey purchased German Eicher tractor and many Massey-licensed Eichers were built. They later sold their interest, and Dromson now owns Eicher which now builds specialized tractors for vineyards and such.

The next big selling model was the MF135, widely popular because of its reliability and power compared with other tractors at the time. This was the first model in the MF 100 series. These included the MF 135, 145, 148, 150, 165, 168, 175, 178, 180, 185 and 188. The same time the MF 100 series came out, the MF 1000 series was introduced. These include the MF 1080, 1100, 1130 and 1150. The 600 series was one of the first tractors to offer the user an option to control where the hydraulic fluid should be pumped. By moving a switch situated near the floor of the cab, the user could block off flow to the rear hydraulics and link arms, concentrating the full force of the pump on the front loader if equipped.
