Torque versus HP

If you want pure pulling torque, forget diesel....think STEAM..!


An 850 H.P. John Deere diesel vs.
a steam tractor rated 18 H.P?
It's all about torque and traction...
enjoy

Yet that steamer would be virtually useless on a modern farm.

An electric motor is another high torque choice. Almost infinite torque available at near-zero RPMs. Just need a big generator (or a really big battery!).

within reason....


steam is slightly better then electric motors... and BOTH have major time/range issues.


ON or OFF road...


as for Steam conversion on a motorhome... ASK Jay Leno and his Crew. His main Service/Repair Garage is Steam Powered.


He and his Crew also restores most Steam Engine Cars.

size is the downfall of steam....an electric motor would be fraction the size and weight of that even with the battery.

I hate threads like this. Its not torque vs horsepower. Horsepower is the rate at which you produce torque.

If you have horsepower, you can always get more torque at the wheels by gearing down. For tow vehicles, focus on engines that produce a high torque number makes sense only because high torque engines mean they produce their horsepower at a low rpm, which is good for durability when used near capacity for long periods of time.

Traction is mostly about weight. A huge boulder would win a tug-of-war with any tractor. Does that make the boulder a good tow vehicle?

Did anyone notice the connecting bar between the Deere and the steam tractor? The angle produces lift on the Deere. Thus, it would be fairly easy to lift the Deere and reduce its traction considerably. If the connecting bar were parallel with the ground this would be a completely different video.

I agree, but even that is not altogether true. It takes much higher cylinder pressures, and the resulting load on all the parts, to get the same horsepower with the low RPM. People like the sound of the slow spinning engine and think that it is just loafing, while in fact every bearing, gear tooth, clutch plate etc. is stressed much more.

CWSQBM - Thank you. I feel better about my prospects of the engine lasting a little longer with my current configuration. I figure I'm getting close to 350 HP and 485 LB/FT. When I get an OBDII scanner, I hope this is confirmed.

Well, that's one way to plow a field, but at the rate their going, it'll be a month before they're ready to seed.

Even though it's flawed, it's still a cool video.

Thanks for posting it.
