Introduction
Oliver 2255 Row-Crop Tractor
The Oliver 2255 is a row-crop tractor manufactured in Charles City, Iowa, USA, between 1972 and 1976. This machine serves as a heavy-duty agricultural platform, recognized for its integration of the Caterpillar 3208 engine, which replaced the 3150 model in 1974.
Engine and Performance
The tractor is powered by an 8-cylinder, liquid-cooled Caterpillar 3208 diesel engine. With a displacement of 636 cubic inches (10.4 L) and a compression ratio of 16.5:1, it operates at a rated speed of 2800 RPM. This power plant provides the necessary torque for demanding field operations, with a manufacturer-rated output of 147 horsepower, often cited at 163 horsepower in performance documentation.
Transmission and Drive
The 2255 is available in both two-wheel and four-wheel drive configurations. It features a partial power shift transmission known as the 'Hydraul-Shift,' offering 18 forward and 6 reverse gears, complemented by a 14-inch dry disc clutch. A simpler 6-speed transmission option was also provided.
Hydraulics and Hitch
The hydraulic system utilizes a closed-center design with a pump flow capacity of 20 gpm (75.7 lpm), supporting between one and four valves for implement control. The rear hitch is compatible with category II/III implements and features draft control, with a total rear lift capacity of 6,000 lbs (2,721 kg).
Operator Environment and Dimensions
The tractor features an open operator station as standard, with optional ROPS available. A climate-controlled cab with heating and air-conditioning could be specified. The machine weighs approximately 16,500 lbs (7,484 kg). Wheelbase dimensions are 108.3 inches for the 2WD model and 83.5 inches for the 4WD version, ensuring stability during heavy-duty traction work.
Conclusion
The Oliver 2255 is a specialized row-crop tractor designed for medium to large-scale farming operations requiring significant pulling power and versatile implement handling. Its reliance on the Caterpillar engine and the Hydraul-Shift transmission makes it a notable example of mid-1970s North American agricultural engineering.
