Introduction
Oliver OC-15 Agricultural Crawler Tractor
The Oliver OC-15 is an agricultural crawler tractor manufactured in Cleveland, Ohio, USA, between 1956 and 1961. With a total production run of 585 units, this machine was engineered for heavy-duty tasks requiring high traction and stability.
Engine and Performance
The tractor is powered by a liquid-cooled, 6-cylinder diesel engine with a displacement of 529 cubic inches (8.7 liters). It produces a net power output of 110 hp (82.0 kW) at a rated speed of 1500 RPM. The engine features a 15:1 compression ratio and utilizes an electric starter system operating on 24 volts.
Transmission and Drivetrain
The powertrain includes a mechanical transmission providing 4 forward and 2 reverse gears. Power is transferred through a 355.6 mm mechanical dry disc clutch, allowing for precise engagement during operation.
Mechanical Configuration and Dimensions
As a crawler-type tractor, the OC-15 utilizes 16-inch tracks to distribute weight and maximize traction across various soil conditions. The machine weighs between 16,835 and 17,335 pounds depending on configuration. Stopping power is managed by mechanical contracting band brakes, and the operator operates the unit from an open station.
Conclusion
The Oliver OC-15 is a robust, specialized crawler tractor designed for demanding agricultural applications where traditional wheeled tractors may lack sufficient traction. Its heavy build and high-displacement engine make it a notable example of mid-20th-century American heavy machinery.
