It's incredible to think that these 100+ year old machines still have enough torque to pull down a building by itself. They only have a few horsepower but unprecedented amounts of torque.

11 million foot pounds of torque at 23 rpm.

I saw this lovely engine at the Great Dorset Steam Fair 2012, a really nice example of how something that doesn't appear pristine really is a piece of engineering prowess.

Steam power unmatched, and it plays a nice tune from hearing the pistons shoot!

People underestimate the serious power of these dignified old gentle giants. This is impressive.

steam traction engines are incredibly powerful, and have tons of torque. it's the nature of steam engines that they develop full torque more or less once the engine starts turning, unlike an internal combustion engine.

Nice pull. The old engine have a lot of power!

1950s , we sometime get late to our school watching this running up and down. what a messy way. thanks for the vedio.

This just shows the power the old technology has. Its amazing!

For a minute i thought that steam tractor was just gonna haul that sled into the woods.

Wow, that is impressive. Never seen a video of a steam tractor pulling. Didn't think steam tractors were very powerful for some reason. I figured it would stall after a few feet, but it just kept going. I liked the throttle work to match power to available traction.

With steam, the closer you come to stalling the more power you get.

The power of steam always wins .this is because of the vast amount torgue at low revs. notice how slow the piston us going but full power!

That was friggin awesome! Thanks so much for posting. RESPECT TO THE KETTLE!!!!

That little beast can pull!

Steam engines are among the most powerful engines made. A good example is the Union Pacific railroad Big boy locomotive they use it to push stalled trains in Wyoming. Steam engines are awesome.😊

Great pull, beautiful sound.

a lot more fun that regular tractor pulls.

H.p.-125, Torque-Yes

Thank you, I am a true fan of anything connected with live steam !
