The Animal, 7 gallons of fuel for 300 feet!
I was looking around You Tube today and found a bit of my past. "The Animal"!
A neighbor of mine in Cohoes had a pulling tractor known as The Animal. I was part of his pit crew back in the 90's. We went to numerous tractor pulls at the county fairs. The Animal has twin Allison aircraft engines designed in 1939. The model V-1710 is a 1710 cubic inch V-12 supercharged engine. The stock engine produced 1250 HP. With tweaks and alcohol racing fuel, that number is pushed up to about 2500. The sled that they pull, has a weight box that slides forward as it is pulled, transferring weight from the sled wheels to the front skid plate. So, it starts off relatively easy, then gets harder as you progress. Tractors of this class typically have about 45000 lbs. loaded for the pull. Bill sold The Animal back about 99. I found this video of a pull from 2018 in Cobleskill. You'll see The Animal about 12 min. into the video.
The tractor originally had 3 engines. It was difficult to keep 3 1939 engines running at peak, in addition to tractor pull regulations putting it in an unlimited class. So, the previous owner dropped it back to 2 engines. 5000 HP still moves things nicely!
The answer is: The Animal. The question: What takes 7 gallons of fuel to move 45000 pounds 300 feet?
And for those that think "Bigger is always Better!", there is the tractor pulls in Bernay, France
