Fun fact about these tractors: because it would run in either direction, you had to be careful when pulling a load up a hill; if you let the engine bog down too slow, it would predetonate and unexpectedly reverse direction, and your tractor would takeoff backwards down the hill
Scary fact. When I was 12 my Parents both had Yamaha RT 180 dirt bikes(2 stroke gas incase you didnt know). We were trail riding and my mom stopped and said her bike wasn't running right. She went to shut it off and it Dieseled for about 15 seconds. That can happen when air cold 2 strokes get hot. We were riding slower trails and she can't ride like my dad and I to keep speed to keep cool so we took a break and grabbed a drink. We gave it 10 minutes and I took it for a test ride.. near us was a decent hill climb especially for a trail bike but I've done it 100s of times on that bike. I hit a rock this time and at the top the engine started to bog. I wasn't going to make it so I pulled the clutch and started dragging front tire down the hill. I let out on the clutch to slow down using the gear as a brake. It let out a loud 2 stroke back fire and rand what seemed like full throttle in reverse back down the hill. Scary AF! Lol. I pulled in the clutch and shut it off. I started it right back up and it ran fine too. My mom was so afraid of it doing it to her on flat land she insisted we trade bikes. I was riding a CR 125 that day. She ended up wanting a race bike after that but wanted a big cushion seat like on her bike..
Very scary. As a lot of people first instance would be to brake. Only to have the tractor tip over, and with these tractor seat that hang out the back...messy

Many years ago I was in a little Niederrhein village, visiting a friend. And there was an elderly gent with a Lanz Bulldog just a few meters down the road. So we stopped by and had a really pleasant chat. According to the guy, the tractor needed anywhere between 20 and 40 minutes to pre heat. He was in the process of doing so while we chatted, with him occasionally checking on the engine. When he finally started it, things happened rather quickly. I was thoroughly impressed by how quickly he yanked the steering column out of the engine once it turned over. He just remarked „Well you really need to watch your hands and arms. If you have them in the wrong place at the wrong time, they will be turned into minced meat. Once thjs thing goes, it goes and it won’t stop. You really need to respect the machine“. He told us that dad had one of his arms very badly injured and almost had to have an amputation when he slipped in the mud while turning the same engine over that we were standing next to. This particular tractor had been in active farm use all the way to the 1970s and was also used to drive some stationary machinery via a long belt over the flywheel. I knew those machines were torque monsters. But 500nm…that is pretty substantial and impressive.
It's pretty charming how we humans tend to familiarize ourselves so much with the machines we work with for a long time. After all this time this old man could've certainly upgraded for something newer and easier to work with, but he chose not to

Nobody had told the soldiers that these needed 2 stroke oil, so they tried to run them on pure petrol. Didn´t went well. He managed to yell at one guy to shut it off - just in time before it would have seized. He repaired it and still had it decades later.

Very cool tractors, I've seen one at a tractor pull and when they are at full power you can feel the shockwaves through your whole body from some distance, pretty impressive but also probably miserable to drive for any extended period of time
My neighbour had lots of Lanz tractors. He used them still in the 80s for his little Farm. After the world war two he moved from near Berlin to our little village. He told me that he saved a few Lanz tractors from the srapyard for 10 Deutsch Mark. The farmers don´t wanted them anymore. The engine start procedere and driving comfort was already outdated at that time. He had a large collection of tractors with nearly every engine Lanz had ever build. One the biggest was a 50 hp Lanz Bulldog. Whenever he started the engine you heard it. The sound was really loud an so unique. His most rare tractor was a 60 hp Eil (fast) Bulldog with an original "Berliner" cabin. The cabin frame is from wood. It is not 100% clear how many original tractors of this type have got survived, but probably just a hand full. I remember that I have often seen cars with numberplates from far away and I heard that many collectors wanted to buy tractors from him, but he never sold any of them. On top of this he owend a few old cars (Mercedes Benz, BMW Isetta, Volkswagen Beetle) and old Motorbikes like DKW, Zündapp and so on. It was always like a museum at his farm. Unfortunatly he died a couple of years ago.

@@johnelliott7375 Everything what I know he was divorced and his son shouldn't get any of this tractors. Two friends of mine where in his testament an got a few tractors and the farm.
My grandpa who passed away last year used to tell me when I was little that back in the day there were these tractors with engines that would run on anything. Many years after I would learn what he was talking about and I'l love to witness one running in person.
These tractors were built under license in Australia under the name of KL Bulldog by the engineering company Kelly and Lewis. Very popular with smaller landowners as they could run on other vehicles used crankcase oil.
They had a few at a vintage tractor pull and you could fell the shock wave from every stroke of engine at full power was fantastic. My grandfather has a Lanz bulldog in Australia running a saw blade and it used to bury itself into the ground with its rocking if you weren't careful
Until you mentioned it, I had never questioned why we use "bulldog" as a synonym for tractor even to this day. I never even considered that it's actually a weird synonym. Thinking back to my childhood, itt's probably the first word I learned for it, even before tractor. Now I know the story behind that
At 4:07 there is a Field Marshal tractor in view, it is very similar to the Lanz Bulldog in having a horizontal single cylinder 2 stroke engine, but the difference is that this is a true Diesel engine, so it won't burn other fuels than diesel and other fuels with a similar flash point like kerosene or some vegetable oils. The Bulldogs with fenders over the rear wheels are Eilbulldogs (speed Bulldogs), these had different gear ratios for a higher top speed and were made for on road haulage.
The Lanz Bulldog was not a true diesel engine. It was a single cylinder hot bulb engine like the Field Marshal tractor. A hot bulb engine has a low compression ratio like 3 or 4 to 1,.a true diesel engine will have a compression ratio of 17 to 22 to 1 ratio en.wikipedia.org/wiki/Hot-bulb_engine?wprov=sfla1
Actually they have a huge fanbase...most of them are retrofitted with elctrical starters nowadays. The so called Eilbulldog(old version of a word with meaning of fast-trac) which was mostly sold to big shipping companies or circuses, costs nowadays more then 200k €. Ones with an open cab and those retrobuild to Eilbulldog design, are sold between 30 and 80k euros. Where i live btw, is a lanzbulldog showcased on meetings of old tractors and agricultural stuff, where an American airplane shot through the flywheel when the farmer was brave enough to plow the field at day...Bulldog still runs 😉😅
I really appreciate the video on this engine VR. These motors are obviously extremely powerful and were popular but I had never knew anything about these before. Thank you!!
I knew about these lovely machines and their MASSIVE single cylinder engine, but never knew the power specs. Thanks for digging that. Impressive figures for its time. Never knew they could run at 0 RPM too, that's a pretty funny trivia. (and the sound of these engines is just fantastic. Slow running big engine are something special, when you can literally hear each piston stroke)
Great content! Back in the 1970s I was I 3rd part share holder in a 1932 model 22/38 here in Christchurch New Zealand. This tractor ended being taken back to Germany. Long may it live!
My dad grew up in a tiny village in the middle of nowhere in germany (Hochsauerlandkreis). All his relatives were farmers. He was super happy that nobody in that village owned a Lanz, because the thing is so terribly loud.
Don't even get me started on how boss these tractors are. There is a lot of them here in Australia. I know a farmer that still has a barrel of crude oil to run theirs on.
Thanks for the informative video, I love these tractors! In the UK we had Field Marshall tractors with a two stroke single cylinder engine, about 6 litres I think, they were started with a shotgun cartridge and were said to be very reliable and economical. I always think that they were a copy of the Lanz Bulldog. Still many to be seen at steam fairs.
Knowing the starting procedure is dangerous and sketchy. Yet, these old tractors are so cool. I love all the variations with rubber tires, all steel wheels, and tracked.
I grew up not far from Mannheim and yes Bulldog was a synonym for tractor. I drove a Lanz for a while around a farm. The 0-rpm back and forth was a thing to watch out for, and it would run the wrong way if not carefully started. But when it ran, it seemed there was nothing that could stop it. One time we were working on the farm around some ditches filled with salt water (it was on an island in the northern sea) and accidentally drove the thing into a deep ditch. We jumped off because it was freezing cold and the water was deep. To our amazement the Bulldog just kept going and drove out at the other side of the ditch after being half submerged in salt water. Somehow we got to the other side and caught it.
Interesting video. There are some points I'd like to add though. After WWII, Lanz developed the hot-bulb engine to a semi-diesel engine. The hot-bulb disappeared and the time-consuming starting procedure was not necessary anymore. The hand start was replaced by a electric starter. The semi-diesel is started with gasoline and a spark plug ignites the fuel until the piston is hot enough to ignite diesel fuel. The driver has to control which fuel is injected to the combustion chamber. Without the hot-bulb, Lanz was able to increase the compression to a medium pressure, which increased efficiency by a lot. Semi-Diesels only need about a third of fuel compared to the the hot-bulbs. Next, Lanz got rid of the gasoline start by adding a glow plug to the combustion chamber. Apart from being horizontal single cylinder two-strokes, these tractors are almost like regular diesel engines. This was about in the mid 50s. This tractor is called "Volldiesel" and was the last development before John-Deere took the majority of shares to expand to Europe. Such a Volldiesel with 16 hp was the first tractor my great-greatparents bought for their small farm here in southern germany. Since Lanz Bulldogs have such a charming sound and a characteristic engine, my father also reimported a D1506 hot-bulb engine from Greece in the 80s. This was the strongest hot-bulb tractor from lanz with 10,3 l and 55 hp. I have some videos about our Volldiesels on my channel. Greetings from from the black forest! (~150 km to Mannheim)
In that day's here in Germany by wintertime they parked the Lanz with distance to the farmhouse. They didn't stop the engine in the evening because of the preheating in the morning to avoid crack's in the glowhead. Imagine to preheat a -25 degrees cold glowhead with a torch you can barely kontrol the heat on.
My uncle was a tank driver in Vietnam People's Army and he told me we used these tracked tractors as training vehicles for tank drivers during the war.
I got deep into the lanz bulldog videos when my kid was about 3. They were/are so awesome, and you did a great job of summarizing why they are so cool!
How great that you made a video about the Lanz! Everybody in Germany that's a bit into tractors knows and loves tha Lanz Bulldog! A really great piece of Technic
@@fidelcatsro6948 How cost? I dont know. No no no its absolutley orginal machine from 1949. Made in Poland. He is a big farmer(1500ha) and this machine is just ornament to his farm;-)
@@fidelcatsro6948 You could probably scoop one up for pretty cheap, especially if it was passed down to the current owner and they don't need it/not know much about it.
Such a good simple design , I live in Australia, every year they do a tractor pull , and to this day the Landz will not stop , wins every year , it pulls down to 50 rpm , nothing can beat it ! They are still used all these years later ! Amazing with 3 to 1 compression .
You could maybe make a video about the "Eil-Bulldog" which was a strange mod of the Bulldog, made it to look like a weird mixture of an old car and tractor. It could make up to 60kph which looks absolutely crazy, if you see this old machines in real life (one time I saw 4 Eilbulldogs running up some mountain road in the black forest, the soundsphere and the sheer velocity of these vehicles were astonishing)
Even though I am an International Harvester guy from the USA I have to say Lanz Bulldog is another one of my favorite tractors. I also found out that Lanz Dealerships in quite a few US states. My dad likes them too and he said I should get one but problem is that it would cost a lot and parts I have a feeling would be hard to find. Thanks for this awesome video of my favorite tractor.
I really like Lanz Bulldogs and I would love to own one just for the hobby of driving one. Here in Croatia the most popular tractor brand is IMT followed by Torpedo. IMT is a licensed Massey Ferguson while Torpedo is a licensed Deutz-Fahr and mostly 06 series was produced. But I love German tractors and my father had a Guldner A3K Burgund and that tractor is robust as a tank. With it's humble 25HP it can outperform the most popular IMT 539 any day. Even my grandfather owned some old 2 cylinder Fahr tractors with 18HP and a Deutz D25 or D30, not sure which one. Best tractors ever, German engineering at it's finest.
The later Lanz tractors such as the Model T had electric starting. There was a separate fuel tank containing a petrol and diesel mix and the hot bulb was replaced by a spark plug. The starter bounced the piston back and forth against the compression until it fired then as soon as it was running you switched it from the petrol mix to straight diesel fuel.
Fascinated by the Lanz Bulldog. I had seen those videos of the thing idling in first gear, jumping back and forth with each piston stroke. Excellent video.
And the result to forward innovation is the gas turbine engine. It can burn any combustible liquid. With the right fuel flow, you can sustain the burn time no matter the energy density of the fuel. It also shares the ridiculously low thermal efficiency if you use light fuel like gasoline. But on heavier fuels, it can reach 50% thermal efficiency. Torque is non existent and it needs a gearbox to produce torque from a high revving turbine.
@@vHindenburg Yep, heard those. You however, ever heard of the multifuel gas turbine engine of the Abrams Tank? It can run on anything as long as its liquid and it burns. That's the peak of multifuel engine. Only a gas turbine can do it. And the only thing you need to change on the fly is its injection flow rate depending on what fuel type.
They do make a beautiful sound indeed. I have the luck to live in a little town, where almost every year there is the biggest meeting of historical tractors in Europe (every 5th year or so the place where they park is closed and due to Covid it also did not take place for a few years). Whenever all the Bulldogs come, you can litterally hear it from kilometres away.
Amazed, fascinated and amused. Top job! Also the TH-cam algorithm deserves thanks for bringing me your channel, incredible variety of engine related vids - your output is eclectic and prolific, kudos!
I love these things! THere is a rather big community around them here (I also saw two of them in this video with license plates from my state) and I'd love to one day drive one.
Here are only tow types of people. The ones that love Lanz bulldog and the ones who love it. Oh wait.... :-) Living in Germany those are still on display on every oldtimer and tractor event. You have to feel the sound. There is nothing else like it. An engine that you can feel running standing next to it. bub bub bub. Thanks for the vid!
The tractor is one cool unit. I how one day I could find me one to buy. I like the slow one cylinder sound. Very similar to a john deere also called a "Johnny Popper"
I used to hate having to start heating the bulb (with a paraffin blowtorch) 30 minutes before I wanted to use the tractor. Other than that it was better than doing things without a tractor!
Another fascinating piece of German engineering for agricultural use is the Universal-Motor-Gerät - the Unimog. It was meant as a combination of a tractor and a truck, allowing a farmer not only doing farm work but also transporting the goods to customers in relatively short time. The Unimog is still made, very versatile and a great off-road vehicle.
My favorite tractor of all time. I was about 4 or 5 when my father first took me to some festival where I've seen Lanz Bulldog for the first time. I fell in love with the sound of that engine. Here in Poland it was very popular until the 1970s I think, when Ursus made the C330 and C360 four cylinder tractors. Before that, Lanz Bulldog and C45 (which is the name of the "stolen" Polish Lanz, produced by Ursus after the war) were probably the only tractors in use here. My father told me many times how he remembers these tractors from his childhood, people driving them to markets or something in the winter wouldn't put the engine down, but they'd instead let them slowly run on neutral, so that the bulb and the engine itself stayed warm for hours. Thanks to that the driver wouldn't have to risk breaking his fingers a lot of times during the day :P Anyway, this thing is in my top of smart engineering. It's simple as hell, but it worked. It suited it's purpose perfectly.
@@vHindenburg it's probably called that way because in the times of creating the tractor factory, Henryk Sienkiewicz's "Quo Vadis" was a hit book. And there was a character called Ursus, which in Latin means "bear" if I recall correctly. The tractors were meant to be strong as the character in the books and a bear, so they called it that way. ;)
That's a hell of a piston design. You can tell that they had to really watch air-fuel mixture so that the flames didn't burn a hole right through the piston head.
I remember the Ursus C-45 based on Bulldog still being used by one of the farmers in the 1980s on the field. Steel wheels, if I remember correctly. You could hear it for miles.
There is a youtube channel called "Lanz Bulldogs im Einsatz". These guys fitted modern linkages and hydraulic systems on some of their Bulldogs and are legit using them for all kinds of work. Not just for fun or show.

Der war verglichen mit vielen anderen in der Sammlung schon recht neu und hatte defintiv einen E Starter. Da standen aber auch einige Glühköpfe und mindestens ein Alldog bei ihm auf dem Hof.
I bet that they came back like Hawks and low balled the widow if their was one. How I hope that it didn't happen.
@@johnelliott7375 Everything what I know he was divorced and his son shouldn't get any of this tractors. Two friends of mine where in his testament an got a few tractors and the farm.
Love your content man, been watching since the early days of engine sound compilations, would love to see a classic throwback to that
Thanks, Jack! Will think about that!
My grandpa who passed away last year used to tell me when I was little that back in the day there were these tractors with engines that would run on anything. Many years after I would learn what he was talking about and I'l love to witness one running in person.
These tractors were built under license in Australia under the name of KL Bulldog by the engineering company Kelly and Lewis. Very popular with smaller landowners as they could run on other vehicles used crankcase oil.
That was our first Bulldog. Later we got a Lanz Model T with electric start.
They had a few at a vintage tractor pull and you could fell the shock wave from every stroke of engine at full power was fantastic. My grandfather has a Lanz bulldog in Australia running a saw blade and it used to bury itself into the ground with its rocking if you weren't careful
Until you mentioned it, I had never questioned why we use "bulldog" as a synonym for tractor even to this day. I never even considered that it's actually a weird synonym. Thinking back to my childhood, itt's probably the first word I learned for it, even before tractor. Now I know the story behind that
At 4:07 there is a Field Marshal tractor in view, it is very similar to the Lanz Bulldog in having a horizontal single cylinder 2 stroke engine, but the difference is that this is a true Diesel engine, so it won't burn other fuels than diesel and other fuels with a similar flash point like kerosene or some vegetable oils.
The Bulldogs with fenders over the rear wheels are Eilbulldogs (speed Bulldogs), these had different gear ratios for a higher top speed and were made for on road haulage.
The Lanz Bulldog was not a true diesel engine. It was a single cylinder hot bulb engine like the
Field Marshal tractor. A hot bulb engine has a low compression ratio like 3 or 4 to 1,.a true diesel engine will have a compression ratio of 17 to 22 to 1 ratio
en.wikipedia.org/wiki/Hot-bulb_engine?wprov=sfla1
Actually they have a huge fanbase...most of them are retrofitted with elctrical starters nowadays. The so called Eilbulldog(old version of a word with meaning of fast-trac) which was mostly sold to big shipping companies or circuses, costs nowadays more then 200k €. Ones with an open cab and those retrobuild to Eilbulldog design, are sold between 30 and 80k euros. Where i live btw, is a lanzbulldog showcased on meetings of old tractors and agricultural stuff, where an American airplane shot through the flywheel when the farmer was brave enough to plow the field at day...Bulldog still runs 😉😅
...that's what the title says? Cult usually means huge following. And you're saying the same thing like it's contradictory?
@@instrumental sry if it sounds like that
@@maxgr7723 you have no reason to apologize to that fool instrumental he's miserable and thinks he's better than you enjoy what you do

Even to this day, in many parts of Germany, "Bulldog" is still used as the colloquial term for a tractor.
Thank you for confirmation
Mostly in southern Germany.
I really appreciate the video on this engine VR. These motors are obviously extremely powerful and were popular but I had never knew anything about these before. Thank you!!
Thank you, it is my pleasure!
Lol they are not powerfully in any way comparatively to any modern engine
They make 40hp for a 10.3 liters engine
Not fuel efficient lol
@@legros731 I was talking about the torque not horsepower.
@@chesspiece81 even the torque is pretty low compared to "modern "diesel that make over 1000lbs torque
I knew about these lovely machines and their MASSIVE single cylinder engine, but never knew the power specs. Thanks for digging that. Impressive figures for its time. Never knew they could run at 0 RPM too, that's a pretty funny trivia.
(and the sound of these engines is just fantastic. Slow running big engine are something special, when you can literally hear each piston stroke)
Oh man, you need to see the exhaust plume of some of these.
Ive seen one push a smoke vortex 30m high, they truly are beautifull
Well at 0 rpm it's making literally no horsepower so it's kinda not really running 😂

Great content! Back in the 1970s I was I 3rd part share holder in a 1932 model 22/38 here in Christchurch New Zealand. This tractor ended being taken back to Germany. Long may it live!
My dad grew up in a tiny village in the middle of nowhere in germany (Hochsauerlandkreis). All his relatives were farmers. He was super happy that nobody in that village owned a Lanz, because the thing is so terribly loud.
Don't even get me started on how boss these tractors are. There is a lot of them here in Australia. I know a farmer that still has a barrel of crude oil to run theirs on.
Thanks for the informative video, I love these tractors! In the UK we had Field Marshall tractors with a two stroke single cylinder engine, about 6 litres I think, they were started with a shotgun cartridge and were said to be very reliable and economical. I always think that they were a copy of the Lanz Bulldog. Still many to be seen at steam fairs.
Knowing the starting procedure is dangerous and sketchy. Yet, these old tractors are so cool. I love all the variations with rubber tires, all steel wheels, and tracked.
I really love the sound they make, any big bore low RPM engine sounds cool, but they have a distinct sound I think.
I grew up not far from Mannheim and yes Bulldog was a synonym for tractor. I drove a Lanz for a while around a farm. The 0-rpm back and forth was a thing to watch out for, and it would run the wrong way if not carefully started.
But when it ran, it seemed there was nothing that could stop it. One time we were working on the farm around some ditches filled with salt water (it was on an island in the northern sea) and accidentally drove the thing into a deep ditch. We jumped off because it was freezing cold and the water was deep. To our amazement the Bulldog just kept going and drove out at the other side of the ditch after being half submerged in salt water. Somehow we got to the other side and caught it.
This channel just keeps getting better 👍✌️🤘
Interesting video. There are some points I'd like to add though.
After WWII, Lanz developed the hot-bulb engine to a semi-diesel engine. The hot-bulb disappeared and the time-consuming starting procedure was not necessary anymore. The hand start was replaced by a electric starter. The semi-diesel is started with gasoline and a spark plug ignites the fuel until the piston is hot enough to ignite diesel fuel. The driver has to control which fuel is injected to the combustion chamber. Without the hot-bulb, Lanz was able to increase the compression to a medium pressure, which increased efficiency by a lot. Semi-Diesels only need about a third of fuel compared to the the hot-bulbs.
Next, Lanz got rid of the gasoline start by adding a glow plug to the combustion chamber. Apart from being horizontal single cylinder two-strokes, these tractors are almost like regular diesel engines. This was about in the mid 50s. This tractor is called "Volldiesel" and was the last development before John-Deere took the majority of shares to expand to Europe.
Such a Volldiesel with 16 hp was the first tractor my great-greatparents bought for their small farm here in southern germany. Since Lanz Bulldogs have such a charming sound and a characteristic engine, my father also reimported a D1506 hot-bulb engine from Greece in the 80s. This was the strongest hot-bulb tractor from lanz with 10,3 l and 55 hp.
I have some videos about our Volldiesels on my channel.
Greetings from from the black forest! (~150 km to Mannheim)
There was a version of the Lanz Bulldog with a factory mounted wood gasifier that had around 14 liters of displacement.
designer : i like bore!
We might need that one again.
@@ragimundvonwallat8961 German colloqium: " Hubraum statt Spoiler."
In that day's here in Germany by wintertime they parked the Lanz with distance to the farmhouse.
They didn't stop the engine in the evening because of the preheating in the morning to avoid crack's in the glowhead.
Imagine to preheat a -25 degrees cold glowhead with a torch you can barely kontrol the heat on.
My uncle was a tank driver in Vietnam People's Army and he told me we used these tracked tractors as training vehicles for tank drivers during the war.
I think the Lanz is very cool. The sound and the torque are amazing. Never heard of a hot bulb engine before this.
Nice video. Lanz bulldog is probably one off the coolest tractor ever. Because off the engine.
I got deep into the lanz bulldog videos when my kid was about 3. They were/are so awesome, and you did a great job of summarizing why they are so cool!
How great that you made a video about the Lanz! Everybody in Germany that's a bit into tractors knows and loves tha Lanz Bulldog! A really great piece of Technic
My neighbor owns this tractor(Ursus c-45 copy 1:1 of Lanz). Absolutley crazy machine;-)
how much do they cost?? lets order one from china, im sure they make them

You could probably scoop one up for pretty cheap, especially if it was passed down to the current owner and they don't need it/not know much about it.

Lanz Bulldog, impressive workhorse. And it's good looking! Thanks for posting.
Thanks, Paul?
Such a good simple design , I live in Australia, every year they do a tractor pull , and to this day the Landz will not stop , wins every year , it pulls down to 50 rpm , nothing can beat it ! They are still used all these years later ! Amazing with 3 to 1 compression .
You could maybe make a video about the "Eil-Bulldog" which was a strange mod of the Bulldog, made it to look like a weird mixture of an old car and tractor. It could make up to 60kph which looks absolutely crazy, if you see this old machines in real life (one time I saw 4 Eilbulldogs running up some mountain road in the black forest, the soundsphere and the sheer velocity of these vehicles were astonishing)
Holy crap that thing looks SICK! I love it.
Sounds like the perfect engine for after the Apocalypse. Runs on anything.
Even though I am an International Harvester guy from the USA I have to say Lanz Bulldog is another one of my favorite tractors. I also found out that Lanz Dealerships in quite a few US states. My dad likes them too and he said I should get one but problem is that it would cost a lot and parts I have a feeling would be hard to find.
Thanks for this awesome video of my favorite tractor.
Thank you, Michael!
I really like Lanz Bulldogs and I would love to own one just for the hobby of driving one.
Here in Croatia the most popular tractor brand is IMT followed by Torpedo. IMT is a licensed Massey Ferguson while Torpedo is a licensed Deutz-Fahr and mostly 06 series was produced. But I love German tractors and my father had a Guldner A3K Burgund and that tractor is robust as a tank. With it's humble 25HP it can outperform the most popular IMT 539 any day. Even my grandfather owned some old 2 cylinder Fahr tractors with 18HP and a Deutz D25 or D30, not sure which one. Best tractors ever, German engineering at it's finest.
Another excellent & exciting topic on Visio Racer Channel. Yup, that Bulldog was really one in a million. What a beast of an engine!
The later Lanz tractors such as the Model T had electric starting. There was a separate fuel tank containing a petrol and diesel mix and the hot bulb was replaced by a spark plug. The starter bounced the piston back and forth against the compression until it fired then as soon as it was running you switched it from the petrol mix to straight diesel fuel.
A 10L engine that you must start using the steering wheel.... that is the coolest.
Until you break your wrists and have to drive with your feet.
@@noobhacker101 If driving a tractor with your feet isn´t cool ... I don´t know what is.
@@noobhacker101 broken wrist is better than ripped off arm
Also cool is a 28L kickstart... Early Rumely OilPulls.

How ironic then that the company that bought them out won't let you work on your own tractor easily.
Crude but extremely fascinating!
I Highly reccomend the Lanz meet in germany each year. Just fantastic traktors and the sound is glorious.
6:31 looks and then also sounds (6:39) like some totally crazy vintage trike racers. Really cool tractors.
Just great what they came up with. Never heard of them. Thanks!
Thank you, Robert!
Fascinated by the Lanz Bulldog. I had seen those videos of the thing idling in first gear, jumping back and forth with each piston stroke. Excellent video.
This tractor is so iconic, every tractor since then is based on this simple thumper.
Anti-theft, take your steering wheel with you. Can't start, or steer! Great video, thanks.
Engines that can burn anything is a path forward and shouldn’t be forgotten.
I'm sure the efficiency is very low, so you'll be busy find stuff to burn
And the result to forward innovation is the gas turbine engine. It can burn any combustible liquid. With the right fuel flow, you can sustain the burn time no matter the energy density of the fuel. It also shares the ridiculously low thermal efficiency if you use light fuel like gasoline. But on heavier fuels, it can reach 50% thermal efficiency. Torque is non existent and it needs a gearbox to produce torque from a high revving turbine.
@@kimpatz2189 Ever heard of Diesel engines?
@@kimpatz2189 lmao. you must live in a cave.
@@vHindenburg Yep, heard those.
You however, ever heard of the multifuel gas turbine engine of the Abrams Tank?
It can run on anything as long as its liquid and it burns. That's the peak of multifuel engine. Only a gas turbine can do it. And the only thing you need to change on the fly is its injection flow rate depending on what fuel type.
These are basically great big maytags and that makes them really cool.
That was the most interesting history on the hot bulb engine, thanks.
Cool old machine, great work
They do make a beautiful sound indeed. I have the luck to live in a little town, where almost every year there is the biggest meeting of historical tractors in Europe (every 5th year or so the place where they park is closed and due to Covid it also did not take place for a few years). Whenever all the Bulldogs come, you can litterally hear it from kilometres away.
Thank you for making this very informative video. Now I want one!
That is a very cool and unique tractor. I haven’t heard of those before.
I want one! Great video as always.
Thanks, Jamie!
Cool video. I love this engine!
3:13 loved the fact that you crank start it using the steering wheel then using it to steer the whole thing.
Amazed, fascinated and amused. Top job! Also the TH-cam algorithm deserves thanks for bringing me your channel, incredible variety of engine related vids - your output is eclectic and prolific, kudos!
Fascinating video! Thanks for making this!
I love these things! THere is a rather big community around them here (I also saw two of them in this video with license plates from my state) and I'd love to one day drive one.
You are my kind of engine nerd. Well done!
Thanks!
Excelent video as always... What a surprise to hear my country's name (Argentina) in it!
Those things sound amazing! Using the steering wheel for starting is the weirdest system I've ever seen.
Here are only tow types of people. The ones that love Lanz bulldog and the ones who love it. Oh wait.... :-) Living in Germany those are still on display on every oldtimer and tractor event. You have to feel the sound. There is nothing else like it. An engine that you can feel running standing next to it. bub bub bub. Thanks for the vid!
I really like the variation in your content, keep it up! 🙂
Thank you!
In Argentina it was manufactured under license, it was called the Pampa tractor and I saw versions with twice the size of the piston.
Back in 2016 I got the chance to drive a 1930s Field Marshal tractor here in the UK was a lot of fun ❤️❤️
I want one of these. I have no use for it but I love old school stuff, especially sketchy old school stuff lol.
Aaaawwwe I wanted to hear more on this, great video mate.
The tractor is one cool unit. I how one day I could find me one to buy. I like the slow one cylinder sound. Very similar to a john deere also called a "Johnny Popper"
I used to hate having to start heating the bulb (with a paraffin blowtorch) 30 minutes before I wanted to use the tractor. Other than that it was better than doing things without a tractor!
Remember how i stood next to a 10.3L one as it was going over a dirt road, the ignitions where so heavy you could feel the ground shaking
Another fascinating piece of German engineering for agricultural use is the Universal-Motor-Gerät - the Unimog. It was meant as a combination of a tractor and a truck, allowing a farmer not only doing farm work but also transporting the goods to customers in relatively short time. The Unimog is still made, very versatile and a great off-road vehicle.
My favorite tractor of all time. I was about 4 or 5 when my father first took me to some festival where I've seen Lanz Bulldog for the first time. I fell in love with the sound of that engine. Here in Poland it was very popular until the 1970s I think, when Ursus made the C330 and C360 four cylinder tractors. Before that, Lanz Bulldog and C45 (which is the name of the "stolen" Polish Lanz, produced by Ursus after the war) were probably the only tractors in use here. My father told me many times how he remembers these tractors from his childhood, people driving them to markets or something in the winter wouldn't put the engine down, but they'd instead let them slowly run on neutral, so that the bulb and the engine itself stayed warm for hours. Thanks to that the driver wouldn't have to risk breaking his fingers a lot of times during the day :P Anyway, this thing is in my top of smart engineering. It's simple as hell, but it worked. It suited it's purpose perfectly.
Its still weird to me that the Polish version is called "Ursus" Its a very German style company name.
@@vHindenburg it's probably called that way because in the times of creating the tractor factory, Henryk Sienkiewicz's "Quo Vadis" was a hit book. And there was a character called Ursus, which in Latin means "bear" if I recall correctly. The tractors were meant to be strong as the character in the books and a bear, so they called it that way. ;)
Wild that the Kawasaki KLR650 had such humble roots.
That was way more interesting that I would have expected tractors to be.
Glad to hear that!
I don`t know where you get this stuff. It`s good shit!👌
That’s what she said
That steering wheel for the crank starter! You can’t loose it!!!! 😂
Insane that such a powerful machine was made so long ago
I saw one driving at a ww2 show, it had crazy loud backfire!
That's a hell of a piston design. You can tell that they had to really watch air-fuel mixture so that the flames didn't burn a hole right through the piston head.
I love machines that pre-date safety.
Let us not forget that natural selection is(was) a good thing.
3:10 - Did he just use the steering wheel as a starting crank? Awesome....LOL!
They didn’t need warning labels on tractors back then; if you could start it you were probably capable of operating it safely.
because it killed all the stupid people that wanted to sue.
I did not know any of this... I DO NOW. Very InTeReStinG. Thank you :)
Glad you learned something new!
I remember the Ursus C-45 based on Bulldog still being used by one of the farmers in the 1980s on the field. Steel wheels, if I remember correctly. You could hear it for miles.
This is so interesting, thanks.
There is a youtube channel called "Lanz Bulldogs im Einsatz". These guys fitted modern linkages and hydraulic systems on some of their Bulldogs and are legit using them for all kinds of work. Not just for fun or show.
After first time watching this video, I asked my grandfather about this tractor. He told me that it was best plowing tractor ever, but extremely dangerous for wood extraction and towing uphill.
Oh wow...havent seen you in a while...glad youre back.

Love the history vids
These vehicles are definitely in smiles per gallon territory. 😂
