Saw this posted on another forum I visit. I kind of like this - shows that old school weight and gearing is still king vs. horsepower and traction.
The leverage afforded by a connecting rod measured in feet, rather than inches, is always gonna win.:laugh:A Formula One race car and a diesel train locomotive each crank out 1000 hp which in my mind makes this a terrible way to measure power output. I know the history behind horsepower (Google it if you don't, it is an interesting story) so I understand the logic... But I fail to see the modern purpose of it. Old steam trains were rated by "Tractive Force" rather than horsepower for exactly this reason. This is also why old tractors had plow ratings to go with their belt and drawbar ratings.
As mentioned before, torque has a lot to do with the drawbar capability of a machine too. Watch the tires on a 830 twist while its hooked to a weight sled and you'll see what I mean. Torque is how the old straight-6 powered pickups could tow circles around small-block V8's... And do it with half the horsepower.
I think the real inequality in this video was weight. The Deere was not exactly a small machine, but I'll bet it was outweighed by the steamer by at least 2 to 1. It clearly had enough power to spin the wheels and dig some impressive ruts, but the steamer's weight gave it more traction. The steamer's wheels barely slipped at all.
What I find most impressive about this video is the chain. I don't care what units you want to use to measure it, there was a lot of power going through that chain!
