The Lanz Bulldog in museum De Locht, Melderslo, Netherlands. Start the engine after a sleep of more than 20 years! Watch my other video if you need a smoother engine!
I didn't know KL but I read that it is the Kelly and Lewis Company in Australia who have built about 900 pcs. between 1949 and 1954. In the Wikipedia article it says that after then, there was too much competition from the Lanz bulldog which was available again after the war. The Lanz Bullog is a 2 stroke medium-pressure engine, somewhere between a diesel and a gas engine, and can combust almost all kinds of fuel.
Most of such old tractors I have seen are usually in a bad state(read: corroted to death), but this one has had some nice owners,who have taken care of this vehicle.
Viele danken - millon de gracias - merci beaucoup - mille graze - thanks a truckload, fella! You made me a delicious moment just seeing this fine-fine videoclip.
Useful tip for starting: When you ignote the gas burner, place 3 rashers of bacon on the cylinder head. Turn once to cook both sides. When bacon is starting to brown nicely, engine should start!
Also called a "semi-diesel," I think, due to the requirement of the hot spot to help ignition along. There are other old engines that would use a hot spot to get ignition going - so-called "hot bulb" engines and "tube ignition," gasoline engines that used a red-hot surface instead of a spark. Interesting stuff.
@Pileggino Hi Pileggino, The Lanz engine is a typical medium-compression engine, the end pressure after compression is somewhere between a typical gas engine and a typical diesel engine. For that reason it cannot ignite diesel fuel when cold. To help starting, the cumbustion chamber is heated from outside with a propane flame. If you want to do it in the style of the Lanz Bulldog, you actually should use a gas burner, as in my other Lanz movie.
It is. I've heard of many injuries where people broke their arm(s) during start attempt. I've seen later models which where started with a crank, which solved that problem. However, I don't know in which year that design change took place. It wasn't custom-made, that's for sure.
Actually, if you are talking comp. ratios, the early hot bulbs typically have the lowest C/Rs of all. This tractor was on the order of 5:1 or less. Also the term "Semi-Diesel" really was a marketing term. There is nothing diesel about them; they have low compression, and low pressure fuel introduction that takes place far closer to BDC than TDC. As well, diesel engines can and do combust virtually all the fuels the Lanzes run on, aside from the well oiled petrol start mix used on some Lanzes.
A 10.3 liter 55HP single cylinder hot bulb engine. Wonder how much torque it produced. I imagine they were not as economical as modern 4 stoke diesel engine tractor, but it is a simple design, They don't make stuff that lasts anymore.
From what I've been told of the Lanz Bulldogs, they had one antisocial and potentially dangerous habit. A very large single cylinder, sometimes they would backfire and the crank could spontaneously change direction. Which, if you're not ready for it, could really ruing your day ploughing a field. Many of them came to Australia as a cheap alternative to the Ferguson, Chamberlain and Fordson machines that were around at the time.
I would be so leary of turning it over like that! Wonder how many have broken their arms/wrists starting those things? However scary it is, sure is an awesome machine though!
As always at such occurrences there has to be an old boy standing in the background giving occasional comments and asides.Did he use one of these tractors when he was working?
The torch is used to preheat the combustion chamber. The compression ratio of this engine is too low to start the engine without preheating. The end pressure after compression is somewhere between a typical gas engine and a typical diesel engine. For that reason it cannot ignite diesel fuel when cold
pieterro80 Not quite. The heating is for the glow plug as the fuel is ignited in the combustion chamber by the heat from the plug. The plug has to get to about 600 centigrades. When the engine runs the plug is kept hot by the combustion. Although they run on diesel they are not diesel engines, but in principle much like 2-stroke model engines used in model airplanes.
hope i get it right. that from part is the glühkopf where combustion takes place. and that has to be brought to -working temperature- with (now) a gas bottle and blower...
Yeah, baby! 2-strokes forever! Otto was an idiot grocery store operator who thought hid ridiculous 4-stroke ("4-JOKE") piece of crap was something good! Day, the inventor of the wonderful 2-stroke is all but forgotten in history. There is nothing on earth more Rube-Goldberg-Ridiculous that the 4-stroke with it's trouble-prone valves, cams, lifters, rockers, etc, and delivers a power impulse every TWO revolutions, and breathes through restrictive valves like a person breathes through a stuffed-up nose! This engine has NO valves, and has only THREE moving parts--piston, rod, crankshaft, and uses the crankcase to not only enclose the crankshaft and rod, but to act as an air pump to provide scavenging air for the 2 stroke principal to operate. It is a hot-bulb engine using a hot surface to ignite the fuel sprayed on that surface. The simplicity and efficiency of a 2 stroke makes pure ridicule of any 4 stroke. Even in locomotives, the EMD 2 strokes will kick the pants off of the ill-running, ill-sounding, "smudge-pot" smoking GE 4-strokes--I have seen a single 2000 HP EMD GP38 pull as much as THREE GE 4400 HP (LIES! more like 440 HP!) HP locomotives, and actually accelerate 5 times faster pulling the same load ALONE! And NO SMOKE! So much for "4 strokes are more efficient that 2 strokes!" Yeah they are--efficient at breaking down, running like crap, and blowing up! Also efficient at sucking fuel like it's going out of style! How did we ever get stuck with assinine Rube-Goldberg Otto Cycle 4 stroke junk anyway? Also, there is no engine more sterile and BORING than the 4-joke! This old tractor is an example of why I hate 4 strokes ans love 2 strokes, and why today's world is all screwed up!
lol you went mad... : ) I don't really like 2 strokes because they have no engine brake. otherwise i drove them during twelve years : a moped and a scooter. both were 50 cc and hauled my heavy ass pretty good. you have better fuel economy with a 4 stroke,even if direct injection on 2 stroke made them really efficient. i agree they are really easy to work on : )

old machines are the best one - this one will propably still work in a hundred years
That is very impressive to see this beast wake up after sitting so long. they just do not make things like they used. great video

Great old tractor - Thumbs up!
THIS is a machine that will die NEVER! pack it out after 200 years,it will start,i´m shure
I do like the sound of the Bulldog and the Field Marshall tractors......
Yes me too!
Prachtig om dit te zien.
Hell, old stuff is a whole lot better than todays shit.. i wish i wanst 11 i wish i was older..lived the good days old cars old music...
Viele danken - millon de gracias - merci beaucoup - mille graze - thanks a truckload, fella!

clever and ingenious (sp?) taking off the steering wheel to -start- the tractor

Old school, built to last.
Looks like it could be a real arm breaker with that starting wheel
I agree, as long as its well maintained it will last along time
Excellent! What a machine.
it is a gas burner which heats the engine head, so it can start, these engines burned just about any fuel. They are called glow heads.
Prachtig flimpke heere ! Sjoean te zeen det dees nog uns aangezjwingeldj waere ! Groete oet Roggel
the two ends of technology in 1949, this on one end and the B-36 on the other!
new machines have to economic and efficient, that makes then not so robust.
It is. I've heard of many injuries where people broke their arm(s) during start attempt.

Good work!
nice sound i could speak like that:)
20 years? Just a nap.
Nice! So the Lanz has a hot bulb engine?

Gaaf ding!

Magnifique !
Awesome!
mooie machine!!

It will probably fly too! :D
As always at such occurrences there has to be an old boy standing in the background giving occasional comments and asides.Did he use one of these tractors when he was working?
nice
I dont know much about tractors, but i loved the sound of Lanz Bulldog playing with a orchestra her on YT. Check it out! :)
"A Tractor cant be one cylindic enough." (Fritz Huber, chief engineer and mastermind of Lanz Bulldog)
Nice.
Congratulations!
Thank you
Why did i see a spark plug in the hot bulb.
Is it for other fuel??
as it has a runaway while hes starting it :O
Do these things ever die?!
they are 2 stroke engines
Do you carry that key on your key-chain
AWESOME!
wth did it start to run away there for a sec or am I crazy?
Erg tof :)
...this bulldog ist it in the back yard?
right hand threads?
Hi its a 2 stroke engine
It is only intended to make starting easier. The engine runs self-igniting, like a diesel, the fuel is injected in a glowing combustion chamber
can somebody please tell me what this piece with the flame is at 2:16?
put your hand on the counter balance
its neat looking i was wondering though, what was the torch used for?
The torch is used to preheat the combustion chamber. The compression ratio of this engine is too low to start the engine without preheating. The end pressure after compression is somewhere between a typical gas engine and a typical diesel engine. For that reason it cannot ignite diesel fuel when cold
Ah i see well i guess that makes sense.

also known as a "hot bulb" engine.
those wear the days things wear built to last
Air cooled?
it is a dutch video
@Hallaran you hav your first thums up !
what is the use of the blue flame @ the front?
is it instead of a sparkplug for fuel combustion?
hope i get it right. that from part is the glühkopf where combustion takes place. and that has to be brought to -working temperature- with (now) a gas bottle and blower...
austrorus
cool :) thnx for the input
doomiz en.wikipedia.org/wiki/Hot_bulb_engine
Oil wont exist long enough to outlast that tractor
thats impressive (Y)
No, water cooled!
Danger!!! you have to learn the correct starting this bulldog. Don't leave the steering wheel in the crank!!! while he ist starting up.... danger!!!
@lanz5016 sehr schön

yeah, but do you believe this is the only reason? think about planned obsolescence; no capitalistic economy will be able to survive without it.
