A standard-tread[1] 1948 Massey-Harris 20.

The Massey-Harris Model 20 was a two-plow tractor built by Massey-Harris (later Massey Ferguson) from 1946-1948.[2] Introduced to commemorate Massey's 100th anniversary in 1947,[2] the 20 was virtually identical to the earlier Model 81, which first appeared in 1941.[3] About 8,000 Model 20s were sold, in row crop or standard models, with the choice of gasoline or kerosene[2][4] (known as tractor vaporising oil, or TVO, in Britain)[5] as fuel. The Model 20 was replaced in 1948 by the Model 22.[1]


With a base price of around C$1450,[6] about C$500 more than the 81,[2] the 20 was competitive with Ford and Ferguson-Brown models of the period.[6]


The bare weight without ballast[7] was 3,000 lb (1,350 kg)[6] (some 700 lb {300 kg} less than the contemporary Model 30, which dramatically outsold it,[2] but about 400 lb {180 kg} more than the earlier 81).[3]


The 124 in3 (2,031 cc)[1][3] engine inherited from the 81, and the 101 before it,[3][4] produced 31 hp (23 kW) at the belt,[8] and was manufactured by Continental, like all Massey Harris tractors at the time.[1][2]


The 20 offered four speeds[6] (against the 30's 5),[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).[6]
