What's amazing about this 30-story behemoth, the world's largest digging machine, is that it's self-propelled; hit the jump for a look at the monster treads. I guess when you have something the length of 2.5 football fields that's nearly 50,000 tons, Vito's Towing isn't gonna be able to move it around for you, so you're better off giving it its own motor. Hate to think of the mileage this thing gets.
