The Massey-Harris Model 20 was a two-plow [1] tractor built by Massey-Harris (later Massey Ferguson) from 1946-1948. [2] Introduced to commemorate Massey's 100th anniversary in 1947, [2] [3] the 20 was virtually identical to the earlier Model 81, which first appeared in 1941. [4] About 8,000 Model 20s were sold, in row crop or standard models, with the choice of gasoline or kerosene [2] [5] (known as tractor vaporising oil, or TVO, in Britain) [6] as fuel. The Model 20 was replaced in 1948 by the Model 22. [1]
With a base price of around C$1450, [7] about C$500 more than the 81, [2] the 20 was competitive with Ford and Ferguson-Brown models of the period. [7]
The bare weight without ballast [8] was 3,000 lb (1,350 kg) [7] (some 700 lb {300 kg} less than the contemporary Model 30 [2], which dramatically outsold it, [2] but about 400 lb {180 kg} more than the earlier 81). [4]
The 124 in3 (2,031 cc) [1] [4] engine inherited from the 81, and the 101 before it, [4] [5] produced 31 hp (23 kW) at the belt, [9] and was manufactured by Continental, like all Massey Harris tractors at the time. [1] [2]
The 20 offered four speeds [7] (against the 30's five), [2] providing a top speed of 2.5 mph (4 km/h) in first (low) and 13.5 mph (21.6 km/h) in fourth (high). [7]
