35 hp never looked so terrifying

watching this will make you appreciate your electric starter motor on your car

I absolutely love this engine because the few mechanisms on it are so incredibly simple and incredibly genius at the same time.

I'd heard of the method of reversing an engine by stopping and starting the fuel at whilst watching the flywheel in conjunction with Field Marshall tractors here in the UK, this is the first time I've ever actually seen it done. Very impressive!

This will become a KZfaq classic one day in everyone's recommended.

I love to see how far we've come from engines like this, true relic you have right there

Love how he is able to change the direction that the motor runs.

Very impressive reversal of rotation at 07:27. Pure machinery romance. Thank you!

It'll run in 100 years too, no problem for these old engines. Very sustainable. That's what I love about these old machines.

I like it how early combustion engines are so similar to steam engines that I can apply my knowledge of steam to this and it translates well

That steady "Whump, whump, whump" is like a mechanical lullaby - superb!

That's why in French, the term "chauffeur" was used. The man in charge of warming up the car's engine.

Great engine , but I really couldn't keep my eyes off the wooden truss brake 😉👍👍🇺🇸

Love it. Makes you appreciate the 7/8k rpms that modern engines have if you see how fast 300rpm is already

Really interesting to see such an engine working, it brought back fond memories of when I was a very young man. I was friends with an elderly farmer who had a vintage crawler tractor that had a single cylinder diesel engine, it was quite a big machine. Unfortunately the steering brakes were worn out so we couldn't drive it but we used it as a stationary engine to run a belt driven saw bench for cutting logs. That was fifty years ago now, and the tractor was from the 1920s, I cannot remember what make it was for certain but it might have been an international. The friend who owned it passed away circa 1980 so I cannot ask him. The engine could be started with a cartridge, but because cartridges were scarce we usually started it manually , with a lighted fuse in the cartridge holder, it took two men with a starting handle to turn it over and get it up to sufficient speed that it would start when the decompression cam running in a groove like a screw thread on the outside of the flywheel dropped off and the compression came in. Like yours it would start with a whump, then gradually pick up speed. It didn't ever run backwards as far as I remember.

Present generation is the most luckiest, blessed with all those modern technology. Now We have mechines that can be started with a button pressing. Thanks to those people who worked really hard for 2 or 3 centuries to give all these comforts to the present generation.

90 years old and it's just getting 'broke in'. Your english is good, the accent adds to the charm of seeing such an old Swedish engine run.

Takes 50 HP to power the 35 HP engine😂 Great video!

It looks like a 2 man job to get that beast going. Thanks for showing off a nice piece of mechanical history.

This looks so beautiful, and sounds so good. Those flywheels are huge on this thing, and starting the engine is some effort and skill!

Was I the only person holding their breath when he was swinging on the flywheel?? Brillant engine and I like your skill to operate it,, well done

The sound is stunning on this amazing machine. Thanks for not spoiling the video with a music overlay.

There were "hot bulb" engines like this that were often used on early powered fishing boats. The "bulb" is a small combustion chamber above the cylinder that is kept hot by the exhaust gas.

Really appreciate the people with the skills to restore, maintain and keep these important pieces of history 'alive'. Great job!.

Amazing piece of engineering history right here. Got yourself a new subscriber.

Your English is great Watching this reminds me of guys starting Lanz Bulldog tractors. I love the sound of this engine.

Truly an art. Thank you for keeping history alive !

Потрясающий агрегат. Обожаю подобные машины. Двигатель Стирлинга, паровые машины, дизели и другие моторы.

Great video. That's a cool old machine! I understood your English perfectly.

Your English is great and the video is interesting. Thank you for making this video.

I love how you can run this engine in either direction just fine. Really wish I had a tractor with an engine like this at home.

I remember some sort of large, open crank engine in the corner of the body shop I worked in back in the mid 70s. Never saw it running. Wish I had paid more attention to it back then. Very cool to see one of these come back to life. Very simple, very robust, very scary when running. I'm sure there were lots of injuries from folks getting body parts in the works.

That’s a cold day to start a big engine by hand the oil would be real thick and it’s hard to turn them over I have the same problem with mine in the winter good video well done

"And i hope that you can understund my English" What? Your English is FAR better than most of KZfaq man!

Fascinating. What a quality-made machine too, seems really well cast and built. Clearly great workmanship has gone into it.

Просто огонь! Вот это сила! А работает, как часы!!

Thanks for a great video being an equipment mechanic and owning antique tractors, I love these old engines. I'm in Canada and there is quite a few Rumley oil pulls around, they sound sweet to especially under load, they set a big ploughing record here in Manitoba a few years ago with them. Quite often I've seen guys stand on the flywheel starting them to and thought you're only going to get a leg caught in that flywheel once, when it fires and a guy slips or don't move quick enough. Take care

I knew at some point caution was going to take a back seat to getting this thing running.

Imagine the huge torque this engine has ! Very impressive !

You’ve got her dialed in nicely, I love how you reversed by throttling off then just at the right moment… great work.

The last time I saw one of these was in 1966 in a small town outside of Frankfort Germany. I was impressed then and also now to. Thank you

What an amazing engine. Looks very powerful

I am so glad i found this, i love these old girls ahead of its time. Thanks for time to post mate.All the best from Australia.

The engines not even running yet and I’m already impressed - by your mechanical sound effects!

Your sound effects made the video something special. Thanks.

Boss: " It's the third time you've been late for work this week." Employee: "Do you realize how difficult it is to start an oil engine when it's 20 below?"

Working with your engines must be a wonderful way to warm up on a cold day!

Appreciate the description of the various components, like the lube and fuel mechanisms for example.

i freaking love watching these things kick off such fun and the history

Nice start up man! It's also neat that it can run in either direction. Thanks for sharing!

I know they are not "clean" engines, but I do love to see and hear these beasts of the past. Thank you, Richard.

I love the way you changed the direction of the engine.

The sound of the engine is so thrilling and yet it is also relaxing due to the rhythm of the chug chug chug. I could watch a video of various engines running for an hour or two and fall asleep to it easily. Awesome machine and awesome video!

I am impressed how it works in reverse mode in the same way as forwards.

Une antiquités agricole! À encore gardé tout son potentiel d'énergie. Belle restauration. Un abonné de France 😉👍

The hefty whim of those flywheels !!! 😳 The momentum, The inertia !! 😳

Imagine how much work that these engines did during the industrial revolution.

I love the fact that this can run in both directions so easily. Quite neat!

This is such an awesome engine. I gotta give it to the guys who made this beast. I love it!

This is crazy. I thought it was an early steam engine at first. It took me a while of wondering why you were talking about 'fuel' to realise it was a massive one piston combustion engine. The miracle and sophistication of modern combustion engines in cars obscures their incredible design and, ironically, it is these (relatively) crude early designs that enable us to wonder at how amazing they are. I sometimes wonder why they weren't invented sooner and the initial assumption is genius designers. But I think as incredible as it is, the design innovation is not the most amazing aspect. I think it is a combination of advances in metallurgy for the parts and chemistry for the fuel, along with a broad and deep supply chain with consistency of quality and reliability in all the industries that contribute. It's really a cohesive social culture that was necessary for such inventions to come about.

in 90 years this will be a classic

Thanks for the upload, there is something about old machinery that leaves you in awe...also reminds me hand cranking some old tractors and how it was just waiting to get you lol

1:42 Perfect description of the water pump sound.

That is one neat bit of kit. Bet your pleased to have that in the shed. Absolutely awesome. 🤟☮️🇦🇺😎👍

Krásný stroj,vzorný majitel,bravo!!!

This is like a freight train. Very hard to get moving but once it's going pretty much unstoppable. GTA5 confirms my last claim

Man that thing is going fast. That's the fastest one I have ever seen. Awesome

Beautiful engine, and keeps you warm starting it too!

I liked when he hit the sweet spot and it ran nice and smooth, no hard chug .

You know you're starting the most masculine engine of all time when you have use your body mass as a flywheel weight.

Puts life into a new perspective. Wish this stuff was still used and educated upon. Great job man. Providence bless you for having the will you keep it alive. 🇺🇸

Beautiful machine! Love the way it can run CW or CCW depending on stating direction.

Love how it reverses

It’s a beast of an engine.

Watching this reminds me a lot of watching my Dad start his old 1530 Lanz bulldog tractor

Love this old machinery. Look how old it is! And still working! 👍🏻

What a machine! Would love to see that monster under load!

beautiful old engine!! its rated 35hp, so for it's size you know why steam fell out of use. I love these old survivors

It’s faster than I thought it would be for the size of the engine. Nice!!

How on Earth did I end up binge-watching people start old engines? So much fun!

What a beast!! Best to have a friendly gorilla on hand to help with starting!

Who else suddenly wants one of these

Elegant, raw power. Anything that takes a beast :) to start it is itself a beast. I'm lovin' this thing. Thanks for sharing!

Incredible. To design and manufacture such a thing…It’s mind-blowing.

That torque generation looks scary high, how much?

Absolutely beautiful engine. Love how you can reverse the direction. I noticed when it first went off that it disrupted the flame on the torch heating the hot bulb. Also noticed a little bit of wisps of air or smoke coming out of the top of that once it was running. Might check to see if there's a crack in the head someplace allowing a bit of compression out.

Obviously an old engine such as this could have benefited from some kind of timing advance. And, your English is outstanding. You and the Dutch always nail it.

I love seeing this kind of older engine still running...very cool! (and, your English is excellent...)

It is very enjoyable to watch such old diesel engines work. Thank you very much for your work.

thats cool how you can reverse the engine

This is so amazing.. it's my first time to see this kind of engine. Yeah im from 90s kids, so i love this kind of good ol stuff.

This is the power of full mechanical system without electronics!

Lol, glow plugs have come a long way huh. :-) Oh and there is absolutely nothing wrong with your English.

90 years old and runs like it’s new.

A thing of beauty ❤❤❤... now if only I could work that hard!

Dude! It appears you can cancel the membership at your health club!! What a workout! Thanks for the video! When I was a kid in the 50's there in south Missouri the "old timers" would periodically put on a show with their old engines and they would typically have some sort of belt driven thrasher so we could see how it worked. Mostly the adults spent their time yelling as us kids for getting to close to the machinery. I remember it was a lot of work and there was a lot of noise. Thanks for your efforts to remind us of the shoulders we are standing on when we use our modern machines.

this is how my parents got to school everyday.. started their model Ts by hand for 15 minutes

I always like watching these old engines start and run. I'm still trying to figure out how it works after a second watch. I'm assuming it's a 2-cycle engine like a modern gasoline 2-cycle because it seems to fire once every revolution and I don't see intake/exhaust valves. Weird seeing such a small fuel tank on something with such a huge piston. It must be very efficient. Reminds me of the gasoline hit and miss engines I saw up in Northern Quebec that were used for generating electricity. They had about the same footprint of this engine but way less mass and lower to the ground. Maybe waist high or so except for the flywheel. It was part of a remote hunting camp. They would run those old generators in the winter time because they only needed electricity for the caretaker's cabin and they were very efficient. They use almost no fuel when they're not under load. They had two that they would alternate due to all the maintenance they required. Plus it was probably nice to have a backup. Would be lonely in the dark up there under 10 feet of snow for 6 months. When the camp was open in the summer they ran a v8 diesel generator to power the whole camp.

I love the overall genius of this engine, and it's sound as well! Would love to buy one like this, can see all types of applications of use for this engine!

im just amazed. this really is a piece of history you got there....
