Introduction
Oliver 1900 Row-Crop Tractor
The Oliver 1900 is a row-crop tractor produced between 1960 and 1964 in Charles City, Iowa, USA. Designed for heavy agricultural duties, it was offered in three progressive versions—Series A, B, and C—with the Series B introducing a more powerful engine and optional four-wheel drive.
Engine and Performance
The tractor is powered by a General Motors 4-53 blower diesel engine. This 4-cylinder, liquid-cooled power plant has a displacement of 212 cubic inches (3.5 L) and operates at a rated speed of 2200 RPM. The engine features a 21:1 compression ratio and uses an oil bath air cleaner to maintain performance in dusty field conditions.
Transmission and Drivetrain
Operators could choose between two transmission configurations: a 6-speed unsynchronized gear transmission or the 12-speed Hydra-Power partial power shift transmission. Both options utilize a dry disc clutch. The machine was available in two-wheel drive or four-wheel drive configurations, with differential dry disc brakes providing stopping power.
Hydraulics and PTO
The hydraulic system provides a pump flow of 13 gpm (49.2 lpm) with a system capacity of 5 gallons (18.9 L). The independent rear power take-off (PTO) supports both 540 and 1000 RPM operation, allowing for the use of a wide range of powered implements. The rear hitch is compatible with category I and II equipment.
Dimensions and Weight
The Oliver 1900 features a wheelbase of 97.25 inches (247 cm) and an operating weight of 12,000 lbs (5,443 kg), which can be increased to 18,355 lbs (8,325 kg) when ballasted. The design includes an open operator station and provides a ground clearance of 23.875 inches (60 cm).
Conclusion
With its robust construction and multiple configuration options, the Oliver 1900 is suited for demanding row-crop farming tasks. Its evolution through the A, B, and C series reflects a focus on improving engine output and operator control, making it a capable machine for historical agricultural operations.
