You know before they start how this is going to go.
Imagine if he had cleats instead of road wheels
Doesn't surprise me. I remember being at a Northern Ill Steam Power event with my Grandfather (who was steam fanatic) many years ago. There was an enormous JD steam tractor that even had steam power steering there hooked up to a 14 bottom gang plow. It effortlessly rolled established sod without skipping a beat. Those machines must have tremendous torque.
And that's no ordinary JD - it's some kind of tractor pulling V8 monster that didn't have a chance against a standard old steam tractor with almost smooth wheels in comparison
I'm not surprised either. Though I am surprised the JD driver agreed to have the two connected via a bar that was not horizontal. When pulling, the angle of the bar would take weight off of his rear wheels and transfer it to the steam tractor.
Related trivia question: What do steam engines and electric motors have in common?
Hint. The answer helps explain the result of the contest in the you tube video.
Instant FULL torque.
Or to put it another way, max torque at 0 rpm, essentially what you said.
Thank you, Steve, for this video.
Like a child with a pull toy.
They both produce nearly their maximum torque at engagement, not requiring high rpm to produce torque.
This video demonstrates tractive effort, something most folks don't understand. They believe it is all about maximum horsepower. The steamer is probably only a 60hp, and the John Deere is 10-20 times that, just doesn't make good use of all that horsepower.
Kevin W. the traction engine you saw was probably a 110 HP Case, you are exactly right they are so large they have steam assisted steering!!
Here is a photo of the 1912 60hp Case on the belt at the American West Heritage Center, with yours truly at the throttle.
My Great, Great Grandfather was killed when one of these had a boiler explosion.
Having lived in the "Burb's" all my life I thought your title was talking about this JD!
My brother who owns several brass era CASE Automobiles, loves to go to tractor meets and show his cars.
His favorite thing to do is ask the John Deere owners if they know why JD's are painted green?
They of course say no why?
He then sez, They are painted green so they can hide in the grass as the CASE tractors drive by!!!!! It works everytime
