The early 20th century saw two visionary brothers from northern Italy revolutionize agricultural machinery. Francesco and Eugenio Cassani, driven by their passion for high-compression engines, embarked on a journey that would change the face of tractors. In 1927, they introduced one of the world's earliest diesel tractors, the 40CV model, which boasted an impressive 40 horsepower. This groundbreaking invention not only marked the beginning of their success but also paved the way for future innovations in diesel technology.

Building on the momentum of their initial success, the Cassani brothers continued to explore advancements in high-speed diesel engines and fuel-injection systems. Their work extended beyond agriculture to marine and aviation applications. Recognizing the potential impact of diesel engines on their nation’s industries, the brothers founded Societa Accomandita Motori Endotermici (SAME) in 1942. Over the decades, SAME evolved into a leading European manufacturer of specialized tractors under various brand names such as SAME, Deutz-Fahr, Hurlimann Gregoire, and Lamborghini.

Innovation has always been at the heart of SAME's progress. The company initially focused on air-cooled, two-cylinder diesel engines, achieving mass production with a smaller 10-horsepower motor. By 1947, SAME unveiled a three-wheel motor mower, the 3R10 Universale, featuring a 10-horsepower diesel engine driving two front wheels. A year later, they launched the more conventional 4R20 Universale tractor with a 20-horsepower engine. One of SAME’s most significant contributions was the introduction of front-wheel-drive (FWD) technology in 1952. This innovation offered superior power transfer on steep terrain and improved ride quality through a leaf-spring suspension system, making tractors more versatile for both fieldwork and transportation.

Throughout the mid-20th century, SAME expanded its engine platforms to include single-, two-, and three-cylinder diesels. Models like the Sametto 120 DT and DA 30 showcased the company’s commitment to delivering reliable and powerful machines. Technological advancements, such as the SAC Automatic Control Unit, ensured precision in operations. As demand for higher horsepower grew, SAME introduced four-, five-, and six-cylinder engines. The company's strategic acquisitions in the 1970s and 1990s further solidified its position as a global leader in industrial diesels. Today, SDF continues to thrive, expanding its reach into new markets and manufacturing facilities worldwide.

Driven by relentless innovation and a forward-thinking approach, the legacy of the Cassani brothers lives on through SAME. Their pioneering spirit has not only shaped the agricultural industry but also inspired generations of engineers and manufacturers. The ongoing growth and diversification of SDF exemplify the enduring impact of visionaries who dared to challenge the status quo and push the boundaries of technology.
