Introduction
SFV 401: Standard-Tread Agricultural Tractor
The SFV 401 is a standard-tread agricultural tractor manufactured by Société Française de Vierzon in Vierzon, France. Produced between 1950 and 1952, this two-wheel drive machine was designed for heavy-duty field operations during the post-war mechanization era.
Engine and Performance
The tractor is powered by a large-displacement, single-cylinder liquid-cooled diesel engine. With a displacement of 778.7 cubic inches (12.8 liters) and a bore/stroke ratio of 250 x 260 mm, the engine operates at a rated speed of 650 RPM. This configuration provides a claimed drawbar power of 40 hp (29.8 kW) and a belt power of 45 hp (33.6 kW), suitable for stationary power tasks and heavy pulling.
Transmission and Drivetrain
The SFV 401 utilizes a mechanical gear transmission system providing 5 forward speeds and 1 reverse gear. This transmission allows for precise speed control necessary for various agricultural implements. The tractor is configured as a two-wheel drive unit, relying on its significant mass for traction.
Dimensions and Chassis
Featuring an open operator station, the tractor weighs approximately 7,275 lbs (3,299 kg). Its physical dimensions include a wheelbase of 76 inches (193 cm), an overall length of 135.8 inches (344 cm), and a width of 71.1 inches (180 cm). To ensure stability and grip, it is equipped with 6.50-20 front agricultural tires and is compatible with either 14-34 or 12-38 rear agricultural tires.
Conclusion
The SFV 401 remains a notable example of mid-20th-century French agricultural engineering. Its simple, robust construction and high-displacement engine make it a durable machine, primarily suited for traditional farming applications requiring steady, high-torque output.
