TL;DR as the RPM drops, the torque increases. Thats why he says "193[rpm], 600[lbft]....188[rpm], 650[lbft]...184[rpm], 900[lbft]" Stolen from another thread: For those interested in knowing a little more about the science behind this, I'll explain a bit about the torque of a steam engine. Steam engines and a DC electric motor are the only two power sources that have 100% torque output at 0 RPM. For a steam engine, this is because the piston is pushed by steam, which is an expansive power source. When the engine is idling at about 250 RPM, the governor that controls the flow of steam to the engine is not very far open, and the steam in the cylinders are not using a lot of the expansive force of steam, as it is in and out of the cylinder so fast. As a load is aplied to the engine, the RPMs will fall off slightly and the governor will open up, supplying the cylinder with more steam. Eventually, the RPMs will fall enough to a point that the governor is just wide open, allowing 100% flow to the engine. This point would be the maximum horsepower point of the engine. This engine was rated from the factory as 110 HP at around 250 RPM. At that RPM range, it can put out around 3,000 lb/ft of torque. From that point on, as the load is increased, the engine RPMs will start to drop off, using the longer time in the cylinder to get more expansive force out of the steam. This leads to the horsepower dropping off, but the torque continuing to increase. The engine will continue to make less horsepower and more torque until it gets down to 0 RPM. At that point, the steam in the cylinder is applying maximum expansive force on the face of the piston. In other words words, 100% potential torque, but no horsepower, as horsepower is dependent upon a motion variable. I hope that makes sense. I tried to keep it all as simple as I could.
Thanks for providing this info - I was a little confused about what the announcer was saying, and I was also curious about the horsepower/torque characteristics of a steam engine
@@jeffanderlik7695 Yes, there is a clutch. So the machine can be used to motor along, or use the flywheel to drive a belt. It's actually on the inner side of the flywheel. Two friction pads that are pushed outward, to engage the flywheel.
Kind of essential when you have a 10ft diameter drive wheel, no? Unfair, I know the drive is geared. I heard its 30:1 ish. That still only gives you 1 1/2 tons of pull.
@@dougaltolan3017 The plow video shows it moving at normal tractor plowing speed digging 32 furrows at once. That’s way more than 1.5 tons at the draw-bar.
Hard to believe this was a reproduction of an original design. Those guy back then knew what they were doing. Horsepower is nice, but torque is what moves you.
160psi boiler pressure on a 14" bore is over 24,630 lbs of force on the face of that piston. This is why steam makes more torque at lower RPM like electric motors - the steam can keep pushing on the face of that piston making huge amounts of force. That's one advantage of external combustion - the fuel is constantly burning and just keeps pushing.
steam is a primitive power source, but if you consider that nuclear powered subs use the same principle ( steam turbine instead of piston ) , beside using uranium rods instead of coal ... so after all, steam ain't out of business yet !
Thats impressive, but nowhere near the torque output of the 4 cylinder triple expansion steam engine the Olympic class liners had. Each reciprocating engine made 15,000 hp at 75 rpm. That is over 1,000,000 ft/lbs. The turbine was also a model of ingenuity. The steam entering the turbine was in a vacuum and below the boiling point of water at atmospheric pressure and still made 16,000 hp (18,000 in Brittanic). The whole powerplant was rated at 46,000 hp yet could make 59,000 hp. From 75 to 83 rpm the reciprocating engines gained 2,500 hp a piece. 8 rpm = 2,500 hp gain.
I am pushing 70 and as far back as I can remember I always felt a very strong connection to these amazing steam powered machines.....the engineering that went into these incredible machines is just amazing and a testament to the generation that created them....plus the detail and all the cool stuff that was incorporated into and onto them like the paint and pinstriping on a lot of these old steamers....
And just to think that the "Big Boy" has 4 steam engines on it, 20,000+ ft/lbs of torque. This tractor is also amazing! I feel a lot of us don'trealize the monstorous power of steam!

The age of steam was impressive. There is a locomotive in my nearby city. I can still remember it going by my childhood home. It was built in the 1920's to produce 90,000 lbs of tractive force. The 5,000 hp. "Madam Queen"
@@Joshie2256 not much at all. It always bothers me when technology is abandoned for the sake of novelty. I suggest you read up on Doble cars. That is very old technology. Had it progressed, we would certainly have steam cars that weigh close to what electric ones do, they'd be almost as quiet, have further range, and be as fast, or probably faster. Someday, we might have small enough nuclear power plants to put in a car. This is not fantasy, it's plausible. People are working on this (actually they're working on smaller things that that). If and when that happens, a steam engine is much more efficient than a thermoelectric generator and motor.
@@KC9UDX But the technology was not abandoned. It just went into full large scale industrial applications like power plants and ship propulsion that even with today's tech behind it still can't break into anything over the ~60% efficientcy range despite having the advantage of the efficiency of size behind it.

There was a farm that would run these in pairs and would line up alongside the field running a thick cable between them. The plow would be pulled with this cable keeping the 35+ ton tractor from compacting the field. This technique may be exclusive to this farm, I’m not sure.
Those old traction engines were very powerful and drove huge bits of machinery. I always wondered what one would do on a dynamometer.... 170hp.... awesome....and torque to burn.....
This reminds me of how African countries still use Steam engines in places because Diesel trains are too expensive for them to repair and while they use Diesel trains more than Steam, the Steam ones are far more reliable and simpler to repair for local workshops. And they also burn just about anything for fuel which is handy in Africa which is VERY poor and fuel is a luxury.
Imagine what steam ships put out. A triple expansion engine would have cylinder diameter of 54 inches for the high pressure piston, 84 inches for the intermediate pressure piston, and 97 inches for each of the two low pressure piston, each with 75 inches of stroke.
@@skunkjobb Interestingly enough, there was actually a car manufacturer called Locomobile around the beginning of the 20th century. They started off making steam cars, and eventually developed into making gasoline powered cars
in spanish there is a difference between hp and cv, the first is hors power and other is caballo de vapor (like "steam horse), the measure of both is different 1hp = 1.014cv
a fun item of note that lots of people never realize is modern society still runs on steam. the newest tech nuclear reactors that keep the lights are just very spicy boilers. Gerald R Ford class carrier from the US Navy? its a steam boat. Some of these engines today run on propane, They were converted to use propane burners just because it increases ease of operation. And its probably cheaper than however much anthricite that thing would need to burn right.
The Natchez in New Orleans is converted to be an oil burner. Most impressive watching the 8 foot or so rams push that paddle. Nothing like it. 1600 or so horse power x 2 (as much as I hate using the term HP being a diesel person)
@@filanfyretracker oh I do not disagree. they definitely use HP. It's just that HP is really a measure of somewhat subjective nature, where torque is a concrete measurable, scientific unit of measure. Torque numbers are what are truly impressive because they are finite. My diesel truck is only 500 hp but the torque is around 850. The 850 is what allows me to tow 20k lbs, not the 500hp. The average joe will not buy a vehicle based on torque though, so car manufacturers need it to sell. I wouldn't be surprised once all vehicles go electric if HP dies with the internal combustion engine.
This one is not so old though. It was built from scratch using the original blueprints provided by Case. Unfortunately no original Case 150's survived to today. But i think this is the best of both worlds, an awesome old machine built with modern steel.
Well I tip my hat to you! She is a beautiful machine! Still the fact of the matter she isn’t even grunting! Should be steam out the stack if pulling hard, or sparks! She is still black, gray!
Remember steam engine has power on both sides of piston travel. Steam power and Chuck Norris have one thing in common. The don't move around the ground, the world moves around them!!
Steam is quite impressive, although quite inefficient and a wee bit dangerous. That's why diesel eventually won out as the workhorse. It may not be able to perform as well as steam for the size and cost, but it is also a lot safer.
The reason that we used cross-belting at times [in my distant youth] was simply to get the right direction of rotation at the load end. This however was when being driven from a pulley on a Fordson Major, which only turned in one direction. Steam engines almost invariably can work in either direction equally well, so I suppose the old traction engines and portable engines driving threshers, etc, would not have needed to cross belts, whatever they were driving. I think they did sometimes use crossed belts though - so it may have been for the reason you propose. Against that, is the fact that it would only be [as you say] a LITTLE more than 180 degrees.
Reading comments and people need to realize the boiler is most important piece when it comes to efficiency, not the piece its driving like a piston, turbine, pump, bladder. Modern designs of pistons are already 96 plus efficient when the capture systems and economies are invested in, not cheap though to design and build and maintain any system.
try to push a piston by hand, it will vary from very hard to impossible depending on size of piston, that shows that you have energy loss by friction thus less efficiency. Making a boiler efficient is nice and all but the rest of the machinery has to be efficient as well
And that is on the flywheel, look at all the reduction gears by the time it gets to the wheels. I wouldn't be surprised if it were making 30,000 ft/pounds at the wheels. Watching a video earlier just in the wheel there is a (about) 4x reduction gear ratio.
A shorter belt would actually be more likely to rip apart. Say a belt can stretch 1% before breaking, a long belt allows a lot more stretch before breaking, a 100 foot belt could have an entire foot of stretch under load where 50ft would be 6"- the force that's stretching it is distributed over a lot more length. Cut that belt in half and it'd take half the force to snap it. It's a little counterintuitive when you think of more modern stuff and like a chain - more links means a higher chance of a weak one letting go - but with a leather or rubber belt...or even nylon straps...it works out a bit differently.
I ran a 25ft belt on my grain grinder belt would slip and grinder would slowly come to stop tractor never lost any rpm put a 100 ft belt on grinder dont stop now when you open the hatch you can put that tractor on its knees and bag for mercy.
Steam power: 150 HP + 50 HP. Diesel Old: 150 HP + 20 HP Gas Old: 150 HP + 10 HP Diesel Modern: 150 HP - 100 HP (Because its always in emissions limp mode) Gas Modern: 150 HP - 20 HP ( Overrated plus burns 300+ HP of fuel to meet emissions compliance)
@@ValentineC137 newer cars and trucks aren’t as efficient because of modern emissions, they give up a lot of horse power and efficiency, ask me how I know.
@@ValentineC137 because generation of NOx occurs at high ignition temperatures (running an engine very lean, burns less fuel, but dirtier). If you burn a little more fuel the flame temperature goes down, emitting less nitrogen oxides.
It is impressive but it's still a little bit of illusion because of very low revs. If you take a modern smaller tractor engine that has 600ft.lb@1500rpm and gear it down to same 180 revs as this and you get what from stump? 5000 ft.lb . of torque. But cannot be mentioned on same day as this one when talking about how cool these are ;)
@@Proffa yes, but a steam engine is opposite a diesel engine, the slower a steam engine is the more torque it will produce, the steam is coming into the bore at a constant pressure. A diesel or petrol engine makes its power by rpm from a single expansion of gas per power stroke.
Even being that these engines drive slowly the amount of talk they have is astounding If I was to have a tractor I would much rather it be steam over gas I think mostly for the coolness factor but just having 5000 foot-pounds of torque just sounds fun😂
when they say 150bhp that is steam horse power (also called boiler horse power ). Boiler horse power is measured in a very different manner. So 150bhp on a steam traction engine equals about 2,000 normal horse power. Torque start at around 5000 lb-ft for traction engines and easily goes way higher depending on the boiler/valve setup.
There's a guy who has any amount of power he needs to run his farm during a major power outage. Might keep the axe and chainsaw handy during that time though.
Keep in mind this is 172 pto horsepower. What it could actually deliver to to the wheels is probably much more than this. Without the wild flappy slipping belt who knows what it could do.
Think I was there that year. RPM was higher and belt was super smooth, engine was causing a little earthquake in that area. Torque fluctuation was sort of wild in this video, not the demo I saw which ran super smooth and much harder.
It is a bit powerful. 171 was the high measured horse power with 5100 footpounds of torque. It may pull a good size tree stump out of the ground. It may even pull the devil out of hell itself.
TL;DR as the RPM drops, the torque increases.
Thats why he says "193[rpm], 600[lbft]....188[rpm], 650[lbft]...184[rpm], 900[lbft]"

When man truly harnessed the power to move the the earth. Brilliant
Love this!! . . I grew up around steam engine collectors in Ohio.
That is one monster of a steam tractor. Probably has to be fired like a locomotive to get enough draft and still have enough coal on the grates.
Yep. Case originally called it the "road locomotive" and you can see why. It's pretty much a locomotive steam engine with tractor wheels.
@@killman369547 In Sweden, we called them locomobiles.
@@skunkjobb Interestingly enough, there was actually a car manufacturer called Locomobile around the beginning of the 20th century. They started off making steam cars, and eventually developed into making gasoline powered cars
Absolutely beautiful machine!
Incredible, what a beautiful tractor too.
Horsepower: a pretty good bit
Torque: yes
When you max out the measuring device and aren't even trying. You've got some power reserve
in spanish there is a difference between hp and cv, the first is hors power and other is caballo de vapor (like "steam horse), the measure of both is different 1hp = 1.014cv
I may go to sleep tonight listening to that chug chugging.
Modern diesel pickups:
"Over 1,000 Ft-lbs of torque- best in class......."
Case 150:
".............yeah, sure, kid."
They way humans thought...it was beautiful
Can't get an actual reading on that but it's lot's of torque. Belt is stopping the reading. 5000+ torque.... yea
We're gonna need a bigger belt
Very cool 😎 so much torque 😀 these festivals are the best. I went to three this year 😀
a fun item of note that lots of people never realize is modern society still runs on steam. the newest tech nuclear reactors that keep the lights are just very spicy boilers. Gerald R Ford class carrier from the US Navy? its a steam boat.
Some of these engines today run on propane, They were converted to use propane burners just because it increases ease of operation. And its probably cheaper than however much anthricite that thing would need to burn right.
The Natchez in New Orleans is converted to be an oil burner. Most impressive watching the 8 foot or so rams push that paddle. Nothing like it. 1600 or so horse power x 2 (as much as I hate using the term HP being a diesel person)
@@KG-sy2vs what do diesels use? in the US all engines are measured in HP. At least from the literature for pickups ive seen.
@@filanfyretracker oh I do not disagree. they definitely use HP. It's just that HP is really a measure of somewhat subjective nature, where torque is a concrete measurable, scientific unit of measure. Torque numbers are what are truly impressive because they are finite. My diesel truck is only 500 hp but the torque is around 850. The 850 is what allows me to tow 20k lbs, not the 500hp. The average joe will not buy a vehicle based on torque though, so car manufacturers need it to sell. I wouldn't be surprised once all vehicles go electric if HP dies with the internal combustion engine.
my grandfather had a 1929 case steam tractor. he share cropped in Kansas with it
I love watching these old beasts work. 5000lbs of torque, that’s some serious work being done.
This one is not so old though. It was built from scratch using the original blueprints provided by Case. Unfortunately no original Case 150's survived to today. But i think this is the best of both worlds, an awesome old machine built with modern steel.
I'm impressed that belt can withstand that much tension.
Amazing! Always wondered “with today’s tech, what could we accomplish “
I wish I can see this engine in person
Imagine just how much torque that the Big Boy steam locomotive is producing! (4 steam pistons about the size of the boiler on that)!
that was a fun year and get to see that big Case
Looked like the belt was going to break before the 150 ran out of power. Kory has to be incredibly proud of this girl.
Very grand tractor and owner.
Love steam tractors. Almost as cool as steam locomotives. :-)
Well I tip my hat to you! She is a beautiful machine! Still the fact of the matter she isn’t even grunting! Should be steam out the stack if pulling hard, or sparks! She is still black, gray!
Remember steam engine has power on both sides of piston travel. Steam power and Chuck Norris have one thing in common. The don't move around the ground, the world moves around them!!
Lots of Chuck Norris jokes, but not a single Clint Eastwood joke - does that mean that Clint Eastwood is no joke?
Well Chuck Norris is still a bad actor despite his kicks and punches
Steam is quite impressive, although quite inefficient and a wee bit dangerous. That's why diesel eventually won out as the workhorse. It may not be able to perform as well as steam for the size and cost, but it is also a lot safer.
Good Lord - That’s impressive.
Really impressive and surprisingly exciting
I’ve never seen belts slap like that on the dyno! Wow
Say I've been here, I walked around that exact dynamo building
Really
Seeing this in person is much more impressionable than the video
Please bring her to the great Oregon steam up in brooks Oregon... Look us up ... Its a hell of a show...
Love this old stuff running. Thank you for sharing and I'm giving you a sub. as soon as I hit send
Oh yeah steam power baby 👶
The belt crosses in the center so that you get a little more than 180 degrees of contact. That's what Dave Richards said.
The reason that we used cross-belting at times [in my distant youth] was simply to get the right direction of rotation at the load end. This however was when being driven from a pulley on a Fordson Major, which only turned in one direction. Steam engines almost invariably can work in either direction equally well, so I suppose the old traction engines and portable engines driving threshers, etc, would not have needed to cross belts, whatever they were driving. I think they did sometimes use crossed belts though - so it may have been for the reason you propose. Against that, is the fact that it would only be [as you say] a LITTLE more than 180 degrees.
More belt wrap on the pullies, gives more traction for the belt
Reading comments and people need to realize the boiler is most important piece when it comes to efficiency, not the piece its driving like a piston, turbine, pump, bladder. Modern designs of pistons are already 96 plus efficient when the capture systems and economies are invested in, not cheap though to design and build and maintain any system.
try to push a piston by hand, it will vary from very hard to impossible depending on size of piston, that shows that you have energy loss by friction thus less efficiency. Making a boiler efficient is nice and all but the rest of the machinery has to be efficient as well
And that is on the flywheel, look at all the reduction gears by the time it gets to the wheels. I wouldn't be surprised if it were making 30,000 ft/pounds at the wheels. Watching a video earlier just in the wheel there is a (about) 4x reduction gear ratio.
Good point! Then again I can’t help but wonder if the mathematics account for flywheel diameter?
With a shorter belt and this thing going flat out it would make even more!
A shorter belt would actually be more likely to rip apart. Say a belt can stretch 1% before breaking, a long belt allows a lot more stretch before breaking, a 100 foot belt could have an entire foot of stretch under load where 50ft would be 6"- the force that's stretching it is distributed over a lot more length. Cut that belt in half and it'd take half the force to snap it.
It's a little counterintuitive when you think of more modern stuff and like a chain - more links means a higher chance of a weak one letting go - but with a leather or rubber belt...or even nylon straps...it works out a bit differently.
The long belt also makes it slip less too due to the weight of the belt itself.
I ran a 25ft belt on my grain grinder belt would slip and grinder would slowly come to stop tractor never lost any rpm put a 100 ft belt on grinder dont stop now when you open the hatch you can put that tractor on its knees and bag for mercy.
Steam power: 150 HP + 50 HP.
Diesel Old: 150 HP + 20 HP
Gas Old: 150 HP + 10 HP
Diesel Modern: 150 HP - 100 HP (Because its always in emissions limp mode)
Gas Modern: 150 HP - 20 HP ( Overrated plus burns 300+ HP of fuel to meet emissions compliance)
last 2 lines are crossed.
How tf would burning more fuel lower emissions
@@ValentineC137 newer cars and trucks aren’t as efficient because of modern emissions, they give up a lot of horse power and efficiency, ask me how I know.
@@woohunter1 they are way more efficient :P
@@ValentineC137 because generation of NOx occurs at high ignition temperatures (running an engine very lean, burns less fuel, but dirtier). If you burn a little more fuel the flame temperature goes down, emitting less nitrogen oxides.
you cannot beat the torque of steam
Too long a flat belt for that test . 5000 ft.lb . of torque . That's impressive .
It is impressive but it's still a little bit of illusion because of very low revs. If you take a modern smaller tractor engine that has 600ft.lb@1500rpm and gear it down to same 180 revs as this and you get what from stump? 5000 ft.lb . of torque. But cannot be mentioned on same day as this one when talking about how cool these are ;)
@@Proffa yes, but a steam engine is opposite a diesel engine, the slower a steam engine is the more torque it will produce, the steam is coming into the bore at a constant pressure. A diesel or petrol engine makes its power by rpm from a single expansion of gas per power stroke.
@@Proffa You cannot make a tractor do 180rpm, it will stall.
@@Senkino5o i don't think that's his point. He wrote "gear it down to 180"
@@Senkino5o he means install a super super low gear
4987 ft/lbs of torque. That's fucking mental.
I remember a British engine achieving 248.5bhp and 3554lbft. This is an impressive machine!
I highly doubt that William.
@@mikezahnow1605 That's cool. You're not very bright and that's OK.
No kidding l heard the announcer say it was a year old.
hah thats a joke. brittish stuff sucks. this thing makes 100 less hp and makes 5252 fllbs . probabably more. thats just what its rated at.
@@jacobpoucher Is that why you see American traction engines all over the world? Oh... Wait...
Even being that these engines drive slowly the amount of talk they have is astounding If I was to have a tractor I would much rather it be steam over gas I think mostly for the coolness factor but just having 5000 foot-pounds of torque just sounds fun😂
when they say 150bhp that is steam horse power (also called boiler horse power
). Boiler horse power is measured in a very different manner. So 150bhp on a steam traction engine equals about 2,000 normal horse power. Torque start at around 5000 lb-ft for traction engines and easily goes way higher depending on the boiler/valve setup.
Where do you get that from? 5000 ft-lb at 200 rpm equals 190 hp. Doesn’t matter if it’s a steam engine or an electric motor, or a turbine.
There's a guy who has any amount of power he needs to run his farm during a major power outage. Might keep the axe and chainsaw handy during that time though.
The real hero is the belt.
THE NUMBERS MASON!!!
awesome video! Love seeing these old dinosaurs pump away!
Keep in mind this is 172 pto horsepower. What it could actually deliver to to the wheels is probably much more than this. Without the wild flappy slipping belt who knows what it could do.
Think I was there that year. RPM was higher and belt was super smooth, engine was causing a little earthquake in that area. Torque fluctuation was sort of wild in this video, not the demo I saw which ran super smooth and much harder.
MY FAVORITE PLACE TO HANG OUT AT ROLLAG !!
It is a bit powerful. 171 was the high measured horse power with 5100 footpounds of torque. It may pull a good size tree stump out of the ground. It may even pull the devil out of hell itself.
World's most powerful steam tractor (CASE)!!!!!
In metric system , it's about 6800 Nm of torque
Simply love that sound
Next would be cool to see how many monster trucks can it pull in a tug of war
All of them😂
@@KG-sy2vs Like all of them combined, or just one?
Nearly 5000 ft lbs of torque holy fuck ! Yes built for pulling .
I would put that steam tractor in a pull-off against any new four-wheel drive tractor today
That's not even fair.
@@KC9UDX I know, they both don't even compare
The belt would have given long before that tractor was out of umphf. And possibly broken the scale.
