The Largest steam-powered tractor in operation is, the '150 HP Case' and weighs 34,000 kg (75,000 lb) and was constructed by Anderson Industries (USA), in Webster South Dakota, USA, in 2018.

The 150 Case steam engine was originally built in 1905 by The Case Company. Only 9 of these massive engines were made, and none survived. Then in 2016, Kory Anderson and his team decided to bring back the giant steam engine to life.

The Tractor is 7.62 m (25 ft) long, 4.3 m (14 ft) wide, and 4.3 m (14 ft) high and packs a 1.4 m ( 4ft ,10 in) long firebox. All this size means this tractor packs a huge punch, producing 6800 Nm (5000 ft lb) of Torque . The tractor is capable of pulling 44 John Deere Plows, that's the same pulling power as 10 F1 cars.

The Case’s massive pulling power comes from a giant 14-inch bore and 14-inch stroke engine. It’s a lazy 200 RPM motor that delivers all its torque from the very beginning. With that kind of weight and torque, the 150 Case has a modest top speed of 5.69 mph.

Kory Anderson and his team took 16 months to recreate this iconic engine from scratch. They had to make it from scratch because none of the original 9 150HP Case engines survived the test of time. However, thanks to Anderson’s passion for steam engines, you can now see the unique traction engine in action.
