The engine is an Iveco. This particular model also powers the New Holland CR's. Not sure if it's the same one that is in the CX or not. Iveco is owned by Fiat, just like CNH. Their main business is to manufacture heavy trucks and engines in Europe. Iveco, CNH and Cummins started a joint venture called the European Engine Alliance in 1996. They are working together to develop new ag engines, primarily for the European market. But, it wouldn't surprise me if Cummins had some involvement with this engine.
