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.
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.
Torque and traction pulls things. That old steam tractor may not be fast but it will drag that sled wherever the operator wants to take it and it won't give a shit what's in its way.
That's the power of steam for you. It easily outmatches internal combination. That traction engine kind of looks like Trevor from Thomas and friends too but needs a serious wash repaint or both
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.
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.
I have seen Daves engine pull lots of times before but missed this pull. Great film+sound. Good pull! One year they had a big Fowler plowing engine on! (That just pissed it!!)
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.😊
A nice pull from a lovely little engine. The front end lifted because the drawbar is too high- it should be below the rear axle instead of even with it. Still, steam power is amazing. A fraction of the power of her modern equivalent, and this little engine scores very nearly a full pull without one bit of wheel slip.
I think what people call power is wrong. "We" are very biassed to horsepower and tend to forget the torque. But power is always a combination between this two. The horsepower of the old steam tractor compared to all that mechanic muscles which were competing that day is probably next to nothing. But the torque will be probably equal to all of them. Result: she only need a little more time, but get the job done. And full pulls are stil rare among the mechanic muscles. But not for steam.
@@jpsholland While pulling with steam I had one sled operator tell me he was worried I was going to rip his sled apart. So just for him I loosened the engine's clutch, that way it would slip before damaging the sled. I actually have had a sled stop the steamer for real. It took the big Lucas branded sled that the mack truck cabs pull to do it. We got to 200 yards and the sled's emergency brakes kicked on. I was at full throttle in the corner notch, Puff puff nope. The only time they've ever actually stalled me.
One of the great advantages of a steam engine is that it does not "stall" like a diesel or a gasoline engine (meaning, it does not turn off when stopped). The steam is still applying pressure to the piston even if the weight is too great for the power given: the engine is still "on." The disadvantages, of course, are the weight, the inefficiency of the machine, the fact that it has to get up to steam to operate (same problem that plagued the Stanley Steamer). But still a simple machine.
This tractor crew shows off the kind of power that was needed to break dry, rocky soil with a gang plow a century ago. Not as flashy as a hot-rod John Deere nowadays but obviously up to the task.
There's also quite a fierce fire at foot level that you could fall into if you're accident prone. Don't ask what happens to boilers when they go wrong!
@mhoyer01 boilers have to be inspected and tested on a yearly basis to receive insurance to operate. you also have to have whats called a steam ticket to run it.
Both steam engines and electric motors share some properties... From what I've read, electrical motors are most powerful at their lowest rpm's (or maybe even a standstill?) From what I've read, it's the same with steam engines? higher steam pressure = higher voltage Larger steam flow (larger pipes and valves) = higher current (thicker wires etc) So which is more powerful comes down to how well you build it and feed it.
Thedeoradude The properties of steam engines depend quite a bit on being able to manipulate the timing and duration of the valves, or at least that's how I understand it... I might be wrong. So I'm guessing with adjustable timing of the electric motors there should be possibilities for better high rpm power too. Perhaps they already do that, I'm not THAT much into electrical motors. They have their advantages but are a lot more boring than steam. :P
Reminder that steam power is used not just in these (beautiful) old beasts, but also in things like nuclear power stations. Where the heat comes from isn't important; steam is POWERFUL.
Steam engines have an absolutely incredible low end torque as long as you can keep the engine from getting stuck on top or bottom dead center- which that huge flywheel they use does a number to avoid. I like how this engine is like "relax I got this." Typical of steam technology, capable of pulling loads far beyond it's ratings. And with the mass of the boiler holding the front end down, it was barely starting to rock the front end up.
At the Western Minnesota Steam Threshing Reunion (Rollag, MN) they have a "Prony brake". This measures the amount of torque an engine is capable of. It was pointed out that steam engines generate their maximum torque when under a full load (like we see here).
steam is actually the best way to make torque. in fact in the 30s i believe there was a steam car that had like 35 horse power but 1000 pounds of pure torque. crazy machines man.
It's hard to stall out when your engine makes more and more torque the slower it turns. Steam engine peak torque is around 2-3RPM, really only just fast enough to be considered turning in the first place, since they feed from a constant source of pressure rather than a pulse of burning fuel. Steam train locomotives were often far too powerful for their own good. They were great at holding speed, but they made so much torque that actually getting started from a dead stop required quite a lot of attention on the part of the engineer lest it just spin the wheels and ruin them/the track. Burnouts with steam locomotives are incredibly easy to do.
Met a lovely lady at the GDSF yesterday. A Marshall Roller, the guy running her caressed her with the occasional wipe of an oily rag (well a lady is entitled to wear a bit of lippy if she's on a day out). Otherwise she was just as she was, plain wonderful.
@doubleboost Close, but no cigar! At half stroke when stationary maximum torque is being produced, but no power. Bhp is a product of torque & revs. So, for example, a steam loco can exert 100,000 ft/lbs of torque on its driving wheels to start a 1000 ton train on the move, but until those big old driving wheels start revolving, however slowly, not a single bhp is being produced. So 10,514 ft/lbs @ 50 rpm = 100 bhp. So does 105 ft/lbs @ 5000 rpm, or 52.5 ft/lbs @ 10,000 rpm.
Steam is amazing stuff, as the thing slowed it upped the compression of the steam going in and the torque increased!!! if we only we could generate heat efficiently, it could replace all sorts of stuff. its already in aircraft carrier catapults and other powerful things like that.
if you think that was cool go to the old threshers reunion. they have 90 steam tractors, a huge building full of steam engines, and a steam train that drives on a circle track around the grounds, and an entire room full of peoples model steam engines.
Actually, steam is extremely efficient. What's polluting here is just how the heat is generated. Many types of power plants use steam with various heat sources. We just use turbines now instead of pistons.
@Polybun Either way, it's a damned feat of engineering using steam from a locomotive boiler at 280 psi to force water back into itself at a higher pressure, a wonder of the industrial world. Although we have a few problems with injectors on the locos, it's usually a "tap it wi' t'hammer" type of job, haha.
Man these are the Machines That Built America man these things you got to realize worked so many different jobs and could haul push-pull you can throw a belt around the flywheel and operate Sawmills and all sorts of other Machinery technically if you had to know how you can hook him up to an electric Dynamo and make them a steam generator for power these were incredibly utilitarian vehicles and really kick-started America's development. The kind of power it had in the capability of hauling was unmatched by anything of the age it was literally like having the power of an entire steam engine on land it took two men at least to operate it one to steer one to manage the throttle steam pessure and fire box
IKR! Were the guys on the back even trying to stall it or does that tractor just have to much low down torque?! Looks like it just needed some weight on the front and it could have pulled even harder!
These ole' steam engines are really neat. They don't make much horsepower. The most powerful steam engines maxed out in the 100-150 hps range, on the low end hps could be in the low to mid teens, but they have an insane amount of torque. 900+ foot pounds for even the smallest tractors, the biggest ones would make multiple thousands of foot pounds. Much more than the diesel engines normally used in tractor pulling. When I first heard about tractor pulling I had wondered someone didn't try using a steam engine. I know why they aren't common, nobody makes steam engines anymore, and for that matter nobody even makes parts for steam engines. But still, I had wondered why somebody hasn't at least tried. Well, turns out they had, and turns out it works pretty damn well. If you'll notice even when the sled was all the way down the tractor was still pulling, slowly but surely. Other than taking over two minutes to go 500 feet (maybe), if given the time and clearance, that tractor would've pulled that sled for miles.
bestial el torque de este tractor, es impresionante realmente el poder del vapor! The torque of this tractor is beastly, the power of the steam is truly impressive!
Geothermal heat is awesome, too, where available. Iceland doesn't even charge individuals for electricity they have such an abundance of electricity. It's even worthwhile for companies to ship ore from Australia to make aluminum there.
No matter how far technology goes... damn I just love steam machines. They are so complex and powerfull. If we only had some other kind of fuel to make steam...
It was a no contest from the start.. But that poor old engine badly needs some love. It looks like it's never had an ounce of it, or a drop of oil- throughout her entire working life. I would love to have a look round on the farm- or wherever she was discovered... as I bet there were many more gems tucked away!

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.
It's all about gearing.
A steam tractor can out pull a diesel one 10 times its horsepower
11 million foot pounds of torque at 23 rpm.
Steam power unmatched, and it plays a nice tune from hearing the pistons shoot!
Nice pull. The old engine have a lot of power!

Thank you, I am a true fan of anything connected with live steam !
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 absolutely great. What a magestic machine. Thanks for posting!
For a minute i thought that steam tractor was just gonna haul that sled into the woods.
Damn sure coulda if it wanted to
good to see people still enjoy these cool old things!
With steam, the closer you come to stalling the more power you get.

Steam tractor is like “step over young diesels I used to run this shit” as it proceeds to show them all how it’s done
Great pull, beautiful sound.
Wow. I was not expecting that. Awesome piece of machinery.
Better yet, it can use any sort of heat source.
A big enough parabolic lense would effectively make it into a solar engine, for instance.

Thats why everything these days is done by steam.

H.p.-125, Torque-Yes
Wow! TORQUE! The old girl looks set to haul that sled right into the middle of next week!
It’ll only be two miles down the road by then though! Lol
Around about the 2 min mark at the end of the track he's just playing with the sled.. LOVVVVe it.
Imagine if the tractor had two cylinders. The torque would be incredible and without any top or bottom dead centres.
Yesss.
That's the way steam trains were assembled. The wheels on one side were mounted on the solid axles 1/4th of a turn ahead of the other side.
I love the huge flywheels on these things.
@mhoyer01

there is no way that things tracks are breaking loose and there is no way you will stall it either, THE POWER OF STEAM
That was unbelievable . It seems as though the torque increased when it slowed a bit. You could pull a house with that tractor .

Steam engines aren't fast but... their torque is unbeatable ;)
Steam locomotives are fast though. Some of the fastest ships were steam when steam turbines came into the industry and even before.
It's slow because it's geared down.
the 1906 land speed record was broken by a stanley steamer @ 127mph...

12 hp and 600 fp of torque.
and good wheels(could be better tho).
nominal hp. times by 8 is more accurate. not bad for a comparatively small cylinder. The power is due to the expansive force of steam.
