Stumbled on this video as the Roku Youtube app is a bit confused by the range of what I watch.
The sound is a bit hard to follow. During the “Discussion” the maker of this beast points out that all of the CASE built versions had rusted away or been scrapped. But he found the blueprints in the CASE archives. So built one!
Yup, he and a few friends built a Brand New Case 150 monster steam tractor. A local foundry made the cast parts. One Off parts were made with laser cutters if I understood him correctly. Also, the blueprints where turned into CAD drawings for a visualization before parts making. Essentially bringing modern Engineering Design tools to the world of 1800s Steam design ;-)
It is refreshing to realize we still have a lot of folks with the skills needed to fabricate things. Even one-off giant things with modestly poor specifications. In an EOTWAWKI event I want folks like him living down the lane ;-)
Lots of photos at this link (including shop work):
“Thank you for visiting the 150HP Case homepage. LET’S KEEP HISTORY ALIVE.” -Kory Anderson, 150HP Case Engineer
While nominally only 150 HP, realize that with such low RPM and long stroke, the torque on that thing will be monster size. A “square” (meaning same size) bore x stroke of 14 inches each. Then no traction issues with a set of cleated iron wheels and 75,000 lbs of weight pushing them into the dirt.
I’ve seen it’s little brother fired up at the UC Davis Picnic Day tractor parade. I thought it was big, but this monster is about 2 x as big.
THE 150 HP CASE IS THE LARGEST STEAM TRACTION ENGINE EVER PRODUCED. Built originally in 1905, zero of them ever lived on – until recreated from scratch in 2018 by Kory Anderson.
The journey of the multi-year build was followed by more than 10,000 followers on Facebook and eventually led to more than 5 million views on YouTube with his legendary “engine pull” in September 2019 at the Western Minnesota Steam Threshers Reunion (WMSTR) in Rollag, Minnesota. This site is a place for steam engineers and hobbyists to learn more about bringing the 150 Case to life.

Here’s a 20 minute video of them doing a World Record plough pull. 44 plow blades all being pulled through the dirt at once. 20-something folks standing on the large platform the tractor is pulling, just to raise and lower the ploughs. I’m impressed with the number of farmers and old hardware folks who showed up.
