Introduction
Oliver 1955 Row-Crop Tractor
The Oliver 1955 is a row-crop tractor produced between 1970 and 1974 by Oliver, a division of White. Positioned as a high-performance machine in its era, it was engineered for intensive agricultural operations, offering a balance of power and mechanical versatility.
Engine and Performance
The tractor is powered by an Oliver-Waukesha 6-cylinder turbocharged diesel engine with a displacement of 310 cubic inches (5.1 liters). It features liquid cooling and is rated at 2400 RPM. This power unit delivers 120 horsepower, providing the necessary torque for heavy-duty field tasks.
Transmission and Drivetrain
The 1955 model offers two transmission configurations: a standard 6-speed gear transmission or the 'Hydraul-Shift' partial power shift transmission, which provides 18 forward and 6 reverse gears. The latter allows for on-the-go shifting between over-, under-, and direct-drive for each gear. The tractor is available in both two-wheel and four-wheel drive configurations, equipped with power steering and differential hydraulic dry disc brakes for maneuverability.
Hydraulics and Implements
The hydraulic system utilizes a closed-center design with a pump flow capacity of 20 gpm (75.7 lpm). The rear hitch is a Category II/III type with a lift capacity of 6,000 lbs (2,721 kg). The rear power take-off (PTO) is independent and operates at 1000 RPM, supporting a wide range of mounted implements.
Dimensions and Weight
The operating weight of the tractor is 11,250 lbs (5,103 kg), with ballasted configurations reaching up to 16,220 lbs (7,357 kg). The 2WD model features a wheelbase of 103 inches (261 cm), while the 4WD version has a wheelbase of 86.25 inches (219 cm). These dimensions provide the structural stability required for heavy draft work.
Conclusion
The Oliver 1955 is a robust, professional-grade tractor designed for large-scale row-crop farming. Its combination of a high-torque turbocharged engine, flexible Hydraul-Shift transmission, and significant hydraulic capacity makes it a suitable choice for operators requiring reliable performance in demanding agricultural environments.
