Introduction
Oliver 1555 Row-Crop Tractor
The Oliver 1555 is a row-crop tractor produced by Oliver, a division of White, between 1969 and 1975. This machine was designed to provide reliable mechanical power for mid-range agricultural operations during the transition period of tractor technology in the late 1960s.
Engine Specifications
The tractor is powered by a 6-cylinder Waukesha-Oliver gasoline engine with a displacement of 232 cubic inches (3.8 liters). It features a liquid-cooling system, a dry-type air cleaner, and operates at a rated speed of 2200 RPM. The engine utilizes an 8:1 compression ratio and is equipped with a 12-volt electrical starting system.
Transmission and Drivetrain
Two transmission configurations were available: a 12-speed Hydra-Power partial power shift transmission, which allows for shifting between direct-drive and a lower range, and a standard 6-speed unsynchronized gear transmission. Both options utilize a 279.4 mm dry disc clutch. The tractor is configured as a two-wheel-drive unit, equipped with power steering and disc brakes for improved maneuverability and stopping control.
Hydraulics and PTO
The hydraulic system is of the open-center type with a total capacity of 14 gallons (53.0 liters) and supports between 2 and 4 hydraulic valves. The rear power take-off (PTO) is independent, offering both 540 and 1000 RPM speeds. The rear hitch is a category II/I type, featuring lower-link draft control to manage implement depth and load.
Dimensions and Operator Station
The tractor has a wheelbase of 99 inches (251 cm) and a shipping weight of 6,841 lbs (3,103 kg). The operator station is an open-platform design, with an optional cab available that included a heater. The front tread is adjustable from 51.5 to 87.5 inches, and the rear tread is adjustable from 56.5 to 89.5 inches.
Conclusion
The Oliver 1555 serves as a versatile row-crop tractor suitable for various field tasks. Its combination of a 58-horsepower engine, multiple transmission options, and adjustable tread widths makes it a practical machine for farmers requiring a balanced tractor for general agricultural use.
