Happy Friday All! This 8.3L Cummins is getting its finishing touches for nothing other than the one special legendary Case IH Magnum 7100 series iconic, high-horsepower row-crop tractor.

The Case IH Magnum 7100 and 7200 series are iconic, high-horsepower row-crop tractors built between 1987 and the late 1990s in Racine, Wisconsin.

Powered by a reliable 8.3L 6-cylinder diesel engine built by the Consolidated Diesel Corporation (a joint venture between Case IH and Cummins).

We made this one better, and built on the foundation of modern machine specifications and capabilities.

What do you think the most iconic 4wd tractor ever built was!?
