The FIAT 480, 500, 540, 580, 640, and 680 DT tractors were a line of powerful and versatile agricultural machines produced by FIAT in the latter half of the 20th century. These tractors were known for their robust construction, reliable performance, and a wide range of available configurations to suit various farming needs. The "DT" designation signified that these models featured a powerful diesel engine, offering impressive torque and fuel efficiency. The 480 and 500 series were considered the smaller, more compact models, ideal for smaller farms and specialized tasks. The 540 and 580 series offered a balanced combination of size, power, and maneuverability, suitable for a wide range of applications. The 640 and 680 series were the largest and most powerful models, designed for large-scale farming operations and demanding tasks like heavy-duty plowing and large-scale harvesting. These tractors were equipped with a variety of features to enhance their functionality, including a three-point hitch system for attaching implements, a powerful hydraulic system for operating attachments, and a comfortable operator cab for improved productivity and operator comfort.
