Introduction

Fiat 451C Agricultural Crawler Tractor

The Fiat 451C is an agricultural crawler tractor produced between 1958 and 1967. Designed for field operations requiring high traction and stability, this machine represents a classic model in the Fiat agricultural range.

Engine and Performance

The tractor is powered by a 4-cylinder, liquid-cooled diesel engine with a 138.5 cubic inch (2.3 L) displacement. It features a compression ratio of 21.5:1 and produces 40 horsepower at a rated engine speed of 2300 RPM. The engine utilizes a firing order of 1-3-4-2 and is equipped with a 24-volt electric starter.

Transmission and Drivetrain

The 451C utilizes a gear-type transmission providing 6 forward speeds and 2 reverse speeds. As a crawler tractor, it relies on steel tracks measuring 12.2 inches in width, which provide the necessary surface area for operation in challenging terrain where conventional wheeled tractors may lack sufficient grip.

Hydraulics and Power Take-Off

The rear power take-off (PTO) operates at a standard speed of 540 RPM, which is achieved when the engine is running at 2160 RPM. This allows for the operation of various mounted and trailed agricultural implements.

Dimensions and Operator Station

The tractor has a wheelbase of 52 inches (132 cm) and a total operating weight of 5534 lbs (2510 kg). It is configured with an open operator station, prioritizing accessibility and direct visibility of the work area.

Conclusion

With its crawler drive system and 40-horsepower engine, the Fiat 451C is designed for agricultural tasks that demand consistent traction and stable handling. Its mechanical simplicity and durable construction make it a suitable machine for heavy-duty field work and specialized agricultural applications.
