The Fiat 640 and 640DT were popular and versatile tractors produced by Fiatagri, a subsidiary of Fiat, during the 1970s and 1980s. They were known for their robust construction, reliable performance, and relatively affordable pricing, making them a favorite choice for farmers and agricultural businesses in various regions. The 640 model came equipped with a naturally aspirated 3.5-liter four-cylinder diesel engine, delivering a maximum power output of 60 horsepower. This model was primarily designed for lighter tasks, like tilling, cultivating, and hauling small loads. In contrast, the 640DT variant featured the same engine but with a turbocharger, boosting its power output to a more substantial 75 horsepower. The added power made the 640DT suitable for heavier agricultural operations, such as pulling larger implements and working on challenging terrains. Both models offered a range of transmission options, including manual and hydrostatic transmissions, allowing operators to select the best fit for their specific needs and working conditions.

The Fiat 640 and 640DT tractors incorporated various design features that contributed to their success. The tractors boasted a durable rear axle, capable of handling heavy loads and transferring power efficiently to the wheels. The robust front axle ensured stability and maneuverability, even when working on uneven terrain. The spacious and well-designed operator cabin provided a comfortable working environment, with ergonomic controls and clear visibility. The tractors were also known for their ease of maintenance, with readily accessible components and straightforward repair procedures. These factors combined helped to establish the Fiat 640 and 640DT as reliable and long-lasting workhorses, making them highly sought-after even in the present day. Their simplicity and durability make them an attractive option for those seeking a reliable and cost-effective tractor for various agricultural tasks, especially in situations where advanced technology is not a necessity.
