Fiat Trattori S.p.A., founded in 1919, emerged as a pioneering force in the agricultural machinery sector, particularly in the realm of tractors. As Italy's leading tractor manufacturer and one of Europe's largest, Fiat Trattori quickly established itself as a cornerstone of the European agricultural landscape. The company's early innovations and robust engineering set a benchmark for tractor design and functionality, making it a trusted name among farmers across the continent. A pivotal moment in Fiat Trattori's history came in 1991 when it strategically acquired Ford-New Holland, a move that significantly broadened its global footprint and product offerings. This acquisition was followed by another landmark event in 1999 when New Holland, under Fiat's ownership, merged with Case Corporation to form CNH Global. Fiat Industrial, as the majority shareholder, played a crucial role in steering this new entity, which became a dominant player in the agricultural machinery market. The consolidation continued in 2013 when Fiat Industrial and CNH Global merged to create CNH Industrial, effectively integrating Fiat Trattori into a larger, more diversified global conglomerate. This merger marked the end of Fiat Trattori as an independent brand but underscored its lasting impact on the industry through its technological contributions and legacy models.
