Guinness World Record Steam Tractor: 150 Case Built from Scratch after 113 Years

Kory Anderson was about 10 years old when he first saw the only remaining boiler for a 150 Case, which was the world’s largest steam tractor in 1905.

He learned that the “Road Locomotive” as it was called no longer existed. The boiler was the closest he could get to the real thing, as all nine of the machines built had long ago been scrapped.

Seeing the boiler inspired him to want to bring the beast of a tractor back to life.

“As a boy, I just hoped my dad or one of my friends or somebody would build it,” he says. “And then as I got older, I realized it was going to have to be me.”

So in 2017, he and dozens of volunteers set out on a mission to build a replica from scratch of the largest steam tractor ever built. Sixteen months and 15,000 hours of work later, the dream became a reality.

And like the 150 Case it is modeled after, Anderson’s 150 is the largest steam tractor in the world – made official by Guinness World Records. (To see the 150 in action, check out the videos at the end of this story.)

But Anderson’s childhood was a little different.
