Introduction
Centaur AG-48 Standard-Tread Tractor
The Centaur AG-48 is a standard-tread tractor produced between 1948 and 1950. Manufactured by Le Roi in Greenwich, Ohio, USA, this model served as a utility machine for mid-century agricultural operations.
Engine and Performance
The tractor is powered by a Le Roi D140 4-cylinder gasoline engine. This liquid-cooled power unit features a displacement of 140 cubic inches (2.3 liters) with a bore and stroke of 3.50 by 3.625 inches. It operates at a rated speed of 1500 RPM, delivering approximately 27 horsepower. The engine intake is protected by an oil bath air cleaner to ensure durability in dusty field conditions.
Transmission and Drivetrain
The AG-48 utilizes a two-wheel drive system. Power is transferred through an unsynchronized gear transmission providing four forward speeds and one reverse speed. Engagement is managed via a dry disc clutch, a common configuration for tractors of this era requiring manual gear selection.
Dimensions and Weight
The tractor has an operating weight of 2,700 lbs (1,224 kg), which can be increased to 3,700 lbs (1,678 kg) when ballasted. It is fitted with 5.00-15 front tires and 9-24 rear tires. The front tread is set at 48 inches (121 cm), while the rear tread is adjustable between 48 and 59 inches (121 to 149 cm) to accommodate various row crop widths.
Conclusion
The Centaur AG-48 is a representative example of post-war American utility tractors. Its simple mechanical design and adjustable tread widths make it a functional choice for light-duty agricultural tasks and a notable subject for historical machinery preservation.
