@@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.
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
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....
This one of those Lee Greenwood moments!. I'm proud to be American! Look at the ingenuity, engineering, and sheer creativity of a group of men a 100+ years ago, and yes the same from a new generation to recreate this. The challenges to the youngsters RECREATING it by the plans was probably as great or greater than the original design and build! I am PROUD TO BE AN AMERICAN.
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!
Please make a video of this again just this time put the mic near the engine and ask the announcer to go have a coffee. The sound when she loads up is incredible. Beautiful engine!!!!

God bless Mr Case for coming up with this Marvel of the early 1900s. That ol gal could pull a 36 Plow and a whole diesel train with the cars behind it and never miss a lick, just keep on going.
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.
@@jetstream454 20 SECONDS? Hah! Do you know how low this thing is "geared"? The flywheel would break off, fly away, and land on the moon if you tried to spin that engine fast enough to reach highway speeds. 0-60 in Nope. You cannot tell me with a straight face that this Tractor does 0-60 faster than a 1966 Ford Bronco and a VW Beetle, which are both geared for road use/highway speeds, if it can even make it to 60 which is a LONG shot lmao
This thing's 160hp is different than a Honda Accord's 160hp, this thing makes 160hp at like 100rpm, a Honda Accord makes it at like 5000, yes 160hp isn't bad for highway speeds, but not in that thing lmao
@@SIRUNOWN So.... Put a stick shift on it. Or, since its going to need a gazillion changes to get to 60 then use a flappy paddle box. Hows that for a mix up of tech?

@@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
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.
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.
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
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.
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.....
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.
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!
Most states, require annual recertification. They test them at 150% rated pressure, by removing the pop off valve and applying pressure. Edit: multiple people have stated that, for safety reasons, the boilers get filled with water which then gets pressurized.
@@jeffanderlik7695 I've heard that when they tested locomotive boilers, they filled them with water so if it did blow there'd be very little "explosion" due to the fact that water is practically incompressable. OTOH, there'd be quite a huge wash of water flying around.
@@jeffanderlik7695 they do NOW. In ohio I remember one blowing up and killing a few people. The boiler was x rayed after the fact and had less than 1/4 the original thickness left meaning it was about as pressure rated as tin foil. Stupid owners were negligent as hell. We had a couple park up on our farm for a few days when I was a kid when doing expos, scared the crap out of me just to be around them. They are truly impressive pieces of machinery, but I will never ever feel comfortable being next to them. Heck, we have 300psi boilers at work that I work 20ft from and are are nearly the size of those tractors, I never feel 100% safe despite the modern safety systems. Steam is a hell of a powerful and devastating force!
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.
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.
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.
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.
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.
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.
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.
Holy crap. At buckley mi we have a big avery but its around 100hp ish but ive never heard any torque numbers before. I knew they were torque monsters but didnt know to that extend
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.
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
Something legitimately “rolling coal”. What a neat piece of machinery!
rolling coal the right way you could say :)

The Case 150 doesn't actually roll. When they engage the clutch, and move the throttle, the Earth starts moving beneath it.
Clutch?
@@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.
@@timgreen4137 not all have a clutch, but I noticed this one after I made the comment.
It's the Chuck Norris of power plants!
@@kleetus92 When they engage the clutch, the tide goes out two hours early.
TL;DR as the RPM drops, the torque increases.

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
Love this!! . . I grew up around steam engine collectors in Ohio.
Simply love that sound
History right in front of us. Amazing piece of American ingenuity. That sound.
Amazing! Always wondered “with today’s tech, what could we accomplish “
I may go to sleep tonight listening to that chug chugging.
....and that's just a relatively small single cylinder - imagine what locomotives put out....
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.
Steam helped make America Great!
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.....
my grandfather had a 1929 case steam tractor. he share cropped in Kansas with it
Love steam tractors. Almost as cool as steam locomotives. :-)
Modern diesel pickups:
"Over 1,000 Ft-lbs of torque- best in class......."
Case 150:
".............yeah, sure, kid."
Who could not💕❤ these AWESOME!!!! machines. They'd have to be FN MENTAL!!! 😡
I’ve never seen belts slap like that on the dyno! Wow
Looked like the belt was going to break before the 150 ran out of power. Kory has to be incredibly proud of this girl.
Imagine just how much torque that the Big Boy steam locomotive is producing! (4 steam pistons about the size of the boiler on that)!
Please bring her to the great Oregon steam up in brooks Oregon... Look us up ... Its a hell of a show...
They way humans thought...it was beautiful
Say I've been here, I walked around that exact dynamo building
Really
I wish I can see this engine in person
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.
Good Lord - That’s impressive.
Really impressive and surprisingly exciting
Outstanding
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!
THE NUMBERS MASON!!!
Are they allowed to run these up to full original pressure? I always thought they ran them at like 50% pressure around crowds for safety.
This engine and boiler are brand new so it has no problem at all running at full pressure.
Most states, require annual recertification. They test them at 150% rated pressure, by removing the pop off valve and applying pressure. Edit: multiple people have stated that, for safety reasons, the boilers get filled with water which then gets pressurized.
@@jeffanderlik7695 I've heard that when they tested locomotive boilers, they filled them with water so if it did blow there'd be very little "explosion" due to the fact that water is practically incompressable. OTOH, there'd be quite a huge wash of water flying around.
@@jeffanderlik7695 they do NOW. In ohio I remember one blowing up and killing a few people. The boiler was x rayed after the fact and had less than 1/4 the original thickness left meaning it was about as pressure rated as tin foil. Stupid owners were negligent as hell. We had a couple park up on our farm for a few days when I was a kid when doing expos, scared the crap out of me just to be around them. They are truly impressive pieces of machinery, but I will never ever feel comfortable being next to them. Heck, we have 300psi boilers at work that I work 20ft from and are are nearly the size of those tractors, I never feel 100% safe despite the modern safety systems. Steam is a hell of a powerful and devastating force!
@@SweetLou0523 right...we are all aware that boilers failed catastrophically, and now we have the pressure checks & recertifications.
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.
you cannot beat the torque of steam
Watching with subtitles only is hilarious 🤣
Incredible ! Amazing !
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.
Cool video. Just curious, why did they use the "World's Longest Belt" for this?
I was going to guess "in case the boiler exploded", but if that happened there might not be any survivors anyway.
What happened when it stopped at 3:17? Did he disengage it somehow? Did the load overwhelm the engine?
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?
How do these develop so much torque in comparison to horse power?
Wow!
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.
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.
4987 ft/lbs of torque. That's fucking mental.
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.
It cuts off during the 3rd pull...wonder how that scored.
I'd like to know how that dyno works! No vid of that in action! How does the load adjust to engine? I see a Toledo scale, that's about it.
Look up Prony brake. Its where the term brake horse power comes from.
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
Holy crap. At buckley mi we have a big avery but its around 100hp ish but ive never heard any torque numbers before. I knew they were torque monsters but didnt know to that extend
Awesomeness
Nice engine
Oh yeah steam power baby 👶
please explain why it must cross the belt, if rotation direction isnt problem
You could throw a chain around the moon and slow down it's orbit with that!
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.
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
The real hero is the belt.
