Introduction
Oliver 1755 Row-Crop Tractor
The Oliver 1755 is a row-crop tractor produced between 1970 and 1975, designed to serve as a versatile utility machine for mid-sized agricultural operations. Manufactured by Oliver, a division of White, this model was offered in both two-wheel and four-wheel drive configurations.
Engine and Performance
The tractor is powered by a liquid-cooled, 6-cylinder Waukesha-Oliver gasoline engine with a displacement of 283 cubic inches (4.6 liters). It operates at a rated speed of 2400 RPM and produces approximately 95 horsepower. The engine features a dry-type air cleaner and an 8.5:1 compression ratio, requiring a coolant capacity of 20 quarts (18.9 liters) and an oil capacity of 8 quarts (7.6 liters).
Transmission and Drivetrain
Operators have access to two primary transmission options: a standard 6-speed forward and 2-reverse gear transmission, or the Hydraul-Shift partial power shift transmission, which provides 18 forward and 6 reverse speeds. The Hydraul-Shift system allows for power shifting between over-drive, under-drive, and direct-drive for each gear. Both systems utilize a 305mm cerametallic disc clutch.
Hydraulics and PTO
The 1755 is equipped with a closed-center hydraulic system with a pump flow of 20 gallons per minute (75.7 liters per minute) and a system capacity of 6.75 gallons (25.5 liters). The rear power take-off (PTO) is independent and offers dual-speed functionality at 540 and 1000 RPM. The rear hitch supports Category I/II and optional II/III configurations, with a maximum lift capacity of 6,000 lbs (2,721 kg) for Category 3 equipment.
Dimensions and Operator Station
The tractor features power steering and differential hydraulic dry disc brakes. It comes standard with an open operator station, though two-post ROPS and cab options were available. The wheelbase measures 103 inches (261 cm) for the 2WD model and 86.25 inches (219 cm) for the 4WD version. The operating weight is approximately 9,600 lbs (4,354 kg), with ballasted weights reaching 13,250 lbs (6,010 kg).
Conclusion
The Oliver 1755 is a robust, mid-range tractor suited for diverse field tasks. Its combination of a high-flow hydraulic system, flexible transmission options, and substantial lifting capacity makes it a reliable asset for farmers requiring a machine capable of handling various implements during the 1970s era.
