Introduction
Fiat 481R: High-Clearance Agricultural Tractor (1961-1964)
The Fiat 481R is a high-clearance tractor produced between 1961 and 1964. Designed for specialized agricultural tasks requiring significant ground clearance, this two-wheel drive machine combines a robust engine architecture with a straightforward mechanical configuration.
Engine and Performance
The tractor is powered by a 2.3-liter (138.5 ci) four-cylinder diesel engine. This liquid-cooled unit produces 40 hp (29.8 kW) at a rated speed of 2300 RPM. The engine utilizes a bore and stroke of 85 x 100 mm and relies on a 24-volt electric starting system.
Transmission and Drivetrain
The powertrain features a manual transmission configuration providing 6 forward gears and 2 reverse gears. Power is delivered to the rear wheels via a two-wheel drive system, operated through manual steering from an open operator station.
Dimensions and Clearance
Built for high-clearance applications, the 481R offers a ground clearance of 24.2 inches (61 cm). The machine has a wheelbase of 85.4 inches (216 cm) and an overall length of 126.7 inches (321 cm). Its base weight is 3616 lbs (1640 kg), which can be increased to 4916 lbs (2229 kg) when ballasted for improved traction.
Electrical System
The electrical architecture is based on a 12-volt system supported by two batteries. The system utilizes a negative ground configuration to ensure consistent operation of the onboard electrical components.
Conclusion
The Fiat 481R serves as a functional, specialized tool for agricultural operations requiring enhanced vertical clearance. Its combination of a reliable diesel engine and adjustable tread widths makes it suitable for row-crop maintenance and general farming duties from the early 1960s.
