Hello; I enjoy this sport. It is awesome. But the snowflakes whining about polluting the air in the comments is more entertaining. This video is about the 3rd round of the Italian Tractor Pulling Championship! There were such a variety of tractors, from the "tiny" turbocharged ones to the Iveco trucks, up to the 10000HP of the four Hemi 8.6-litre supercharged V8 engines or the 9000HP of the three Allison 28-litre V12 aircraft engines! And what about "The Joker" powered by a Curtiss Wright R-3350 radial 18 cylinders engine, the same engine of the Boeing B-29 Superfortress? At 3:00 those trucks are cool. We dont have ones like that here in the US. Nice video! Greetings.
