Expert Overview of the Fiat 640 Utility Tractor

The Fiat 640 utility tractor, manufactured from 1973 to 1978 in Moderna, Italy, stands as a testament to Fiat’s engineering prowess and commitment to quality in agricultural machinery. This versatile tractor, available in both 2WD (640) and 4WD (640DT) variants, has earned a reputation among farmers and agricultural experts for its robust construction, reliability, and adaptability to a wide range of farming tasks.

At the heart of the Fiat 640 is the Fiat 8045-02 diesel engine, a 4-cylinder, liquid-cooled powerhouse that delivers 64 horsepower. This engine is renowned for its durability and efficiency, utilizing direct injection technology for improved fuel efficiency and performance. With a displacement of 3.5 liters and a compression ratio of 17:1, the engine provides ample torque, peaking at 156.4 lb-ft at 1600 RPM. This ensures that the tractor can handle heavy-duty tasks with ease, making it suitable for both small-scale and large-scale farming operations.

The Fiat 640’s transmission system is another highlight, featuring a gear type setup with eight forward and two reverse gears. This allows for precise control and flexibility in various farming conditions. The optional creeper range adds to its versatility, enabling ultra-low-speed operations which are crucial for specific agricultural tasks. The manual steering system, combined with the sturdy 4×2 2WD or 4×4 MFWD 4WD chassis options, provides excellent maneuverability and stability, even on challenging terrains.

One of the key aspects that set the Fiat 640 apart is its hydraulic system. With a pump flow of 5.8 gallons per minute, the tractor can efficiently power various implements, enhancing its utility on the farm. The tractor hitch, compatible with Type II/I implements, can lift up to 4079 pounds at the ends, making it suitable for a wide range of equipment and attachments. This adaptability is crucial for modern farming, where the ability to switch between different tasks quickly and efficiently can significantly impact productivity.

The Fiat 640 also pays attention to operator comfort and safety. The four-post ROPS (Roll-Over Protective Structure) cab provides essential protection, while the ergonomic layout of controls ensures that the tractor is user-friendly, even during long hours of operation. The tractor’s dimensions, with a length of 125 inches for the 2WD and 132.3 inches for the 4WD version, and a weight ranging from 4961 to 6174 pounds, strike a balance between sturdiness and ease of use.

In summary, the Fiat 640 utility tractor is a reliable and versatile machine that has stood the test of time.
