Early Oliver Tractors

In 1937, the Hart-Parr Oliver 70 tractor took on a new streamlined look and became the Oliver 70. Gone was the name Hart-Parr from radiator housing. The cast iron shell had been replaced by a stamped steel housing. This streamlined model was available in several variations: row crop with single front wheel, dual front wheels or wide front axle. It was also available as a standard, orchard and an industrial model. The tractor had a six-speed transmission but 5th and 6th gear were blocked out on models sold with steel wheels.

In 1937 the 18-27 Row Crop and 18-28 Standard were replaced by the 80. The 80 was built as a standard or row crop variation. This 3-plow model continued to use the Waukesha/Oliver engine. Oliver experimented with putting a Buda diesel in the engine but a very limited amount of these were built and out of 136 tractors only a few of them are known to exist today.

The model 28-44 was upgraded to the model 90 in 1937 and the high compression model became the 99. The 90 and 99 were only built in a standard version. The 90 could burn gas, kerosene or distillate.

The Oliver 60 was introduced in 1940 and had the same styling as the streamlined 70. It used the Waukesha/Oliver gasoline engine and was sold as a standard, row crop or industrial model. It was Oliver’s biggest little tractor and developed 17.85 drawbar horsepower.
