This is the maddest tractor you'll probably see the whole day. Its owner took out this tractor's original engine and replaced it with a turbocharged unit taken off a Volvo 240. Imagine doing burnouts, donuts and drifting with those huge wheels at the rear. Well, you don't really have to imagine it. You can just watch this clip. They call this little toy "The Terror" and for good reasons. Unfortunately, we're not really sure about how many horsepowers it has, but we're pretty sure there are a lot of them.
