Presented by Case IH as the world’s most powerful self-propelled forage harvester at Agritechnica in 1997, the Mammut 8790 would undergo further field tests and trials throughout 1998, and the first production machines duly hit the market for the following season.

Case IH acquired the forager in 1997 when it took over the Bidell Group, which included Mengele and the Fortschritt factory in Saxony where the Mammut 8790 was being developed. 544hp and a large drum The Mammut 8790 had a 16.0-litre Deutz V8 engine with a rated output of 544hp. At the time, this was around 50hp more than any of its competitors could call on. However, this Deutz motor was swapped for an even more powerful 570hp Daimler-Chrysler engine from the 25th machine produced.
