John Deere Numbered Series – Models 50, 70 and 80 from the 1950s that replaced the old lettered series at Waterloo, two-cylinder engines from 3.1 to 7.7 litres, 20.6 to 50 kW in diesel, petrol, LPG and multi-fuel form
This page brings together the John Deere Models 50, 70 and 80, with which the maker replaced its older lettered series with two-digit model numbers in the early 1950s at Waterloo, Iowa. The Model 80 of 1955 was John Deere's first production diesel tractor, while the 70 and 50 were additionally offered with petrol, LPG and multi-fuel engines. All models are built around the marque's characteristic horizontal two-cylinder engine.

The register lists here 4 versions with 20.6 to 50 kW (28 to 68 hp) from two-cylinder engines displacing 3,111 to 7,726 cc. Unladen weights range from 2,300 to 3,861 kg, torque from 237 to 510 Nm at a rated speed of 975 to 1,250 rpm. Fuel types depending on the model span diesel, petrol, LPG and multi-fuel operation.
With the Numbered Series, John Deere rose to become a leading US tractor maker in the 1950s; the marque's characteristic two-cylinder with its deep exhaust beat shaped the brand's image for decades, before the New Generation series switched to multi-cylinder engines in 1960.
When buying used, check the condition of the two-cylinder's head and crankshaft, the tightness of the fuel system depending on engine variant, the clutch and gearbox, and rust on sheet metal and fenders. Parts are supplied by specialist vintage-tractor dealers and the John Deere network.
