Oliver tractors were known for their powerful engines compared to competitors, and their attention to styling.

Oliver's emphasis on styling strongly influenced offerings by competing brands such as Farmall and John Deere.

A KD version operated on kerosene and distillate fuel.The tractors were styled with automobile-like sheet metal full hood enclosures, giving them a streamlined look, and car-like controls.

A competition was held to determine the 70's paint scheme, with voting at county fair exhibits promoting the tractor.

Despite the 70's features, the model was outsold by the equally innovative and less expensive Ford 9N tractor.

Demand was high for the model, and some were delivered in Oliver green and red colors until 1940.

[6][7] The Oliver 77 was introduced in 1947, replacing the 70 with minimal changes, apart from styling updates, a standard three-point hitch, and an option for an electric equipment lift.

The new line was more squared-off in appearance, retaining the green body and replacing previous models' yellow and red highlights with a green-tinged white for grilles and wheels.

The engines remained the same, with a slightly higher RPM and compression ratio, yielding about 10% more power.
