Introduction

Oliver 1850 Row-Crop Tractor

The Oliver 1850 is a row-crop tractor manufactured between 1964 and 1969. Engineered for versatility, it served as a primary power unit on mid-to-large scale farms during the 1960s, offering configurations for both two-wheel and four-wheel drive operations.

Engine and Performance

The tractor is powered by a liquid-cooled, 6-cylinder Waukesha-Oliver engine with a displacement of 310 cubic inches (5.1 liters). Featuring a 9:1 compression ratio, this engine was designed to deliver 102 horsepower. It utilizes a 12-volt electrical system and requires 20 quarts of coolant and 12 quarts of oil for standard maintenance.

Transmission and Drivetrain

Oliver offered three distinct transmission types for the 1850 to accommodate various operational needs: a standard 6-speed unsynchronized gearbox, a 12-speed Hydra-Power partial powershift, and an 18-speed Hydraul-Shift partial power shift introduced in 1967. The latter allowed for on-the-move shifting between underdrive and overdrive ranges. All models are equipped with a 330mm dry disc clutch and differential disc brakes.

Hydraulics and Hitch

The hydraulic system is of the open-center type, providing a pump flow of 15.9 gallons per minute (60.2 liters per minute) at a pressure of 2500 psi. It supports between two and four valves for implement control. The rear hitch is Category II, with an optional Category III configuration, capable of lifting 6,000 lbs (2,721 kg) at 24 inches behind the lift point.

Dimensions and Operator Station

The 1850 features an open operator station, with the Continental Cab available as an optional add-on, including air-conditioning. The 2WD model has a 103-inch wheelbase, while the 4WD version measures 86.25 inches. Adjustable tread widths for both front and rear axles allow the tractor to be adapted to different row spacings.

Conclusion

With its robust Waukesha-Oliver engine and multiple transmission options, the Oliver 1850 remains a significant model from the mid-1960s. Its combination of hydraulic capacity and adjustable tread settings makes it a capable machine for varied agricultural applications, suitable for collectors and operators looking for a reliable vintage workhorse.
