Introduction

Oliver 66 Row-Crop Tractor

The Oliver 66 is a row-crop tractor produced between 1949 and 1954 in Charles City, Iowa, USA. As part of the Oliver tractor lineage, it was designed to provide a versatile and robust solution for agricultural operations of the mid-20th century.

Engine and Performance

The tractor is powered by an Oliver-Waukesha 4-cylinder diesel engine. This liquid-cooled, vertical I-head power plant features a displacement of 129.3 cubic inches (2.1 liters) and operates at a rated speed of 1600 RPM. With a compression ratio of 15.5:1, the engine delivers approximately 27 horsepower, suitable for various field tasks.

Transmission and Drivetrain

The drivetrain utilizes a two-wheel drive configuration paired with an unsynchronized gear transmission, offering 6 forward speeds and 2 reverse speeds. Power is transferred through a dry disc clutch, providing the operator with manual control over gear selection for different field conditions.

Hydraulics and PTO

The Oliver 66 is equipped with an independent rear power take-off (PTO) operating at 540 RPM, allowing for the consistent powering of implements regardless of tractor motion. Implement control is managed through the Oliver Hydra-Lift hydraulic system.

Dimensions and Chassis

Built on a wheelbase of 86.75 inches (220 cm), the tractor features a ground clearance of 24.4 inches (61 cm), facilitating operations in varying crop heights. It utilizes manual steering and contracting band brakes for handling. The tire configuration includes 5.00-15 front tires and rear options of 8-38 or 9-38, providing necessary traction for row-crop applications.

Conclusion

The Oliver 66 represents a functional and reliable agricultural tool of its era. Its combination of a 27 hp diesel engine, independent PTO, and row-crop design made it a suitable choice for farmers requiring a maneuverable machine for standard cultivation and tractive tasks.
