Torque + weight vs. Horsepower

A modern John Deere tractor with 850 horsepower plays tug of war with an 1800s era steam tractor that has about 18 horsepower. While both are capable of getting an honest day's work done, there is only one that proves its dominance through sheer power.

Torque beats horsepower at low speeds.

Old and crafty beats young and enthusiastic every time.

I don't believe that the John Deere has a 850 hp tractor engine. It looks like it has been fitted with a V8 car engine, high hp and torque at high RPM, not so much at lower RPMs. Steam engines can deliver their maximum torque at low (sometimes zero) RPMs, so the Deere is at a major disadvantage.

In my (limited) experience, even very large Deere farm tractors rarely have more that 300 - 400 hp

They are not fairly hitched. The connecting strap needs to be horizontal to be fair. The steam engine is not only pulling. It is lifting the opponent upward and reducing traction of the modern tractor.

Old and crafty against young and dumb. The JD is not ballasted properly either. If it had dual rear tires it would get some of its torque to the ground. The old bigger tractor loses nothing to wheel slip.

I think the sheer weight of the old tractor gave it a YUGE advantage. If the Deere were weighted down in the rear it would be able to get some traction.
