Engine running backwards? Lanz Bulldog Tractor two stroke
ฝัง

- This Lanz Bulldog tractor can run both ways! Here is my dads antique Lanz Bulldog 45hp in action. Quite a unique design! This is a two stroke hot bulb engine and it is capable of running at very low rpm and even firing at zero/ 0 rpm.

Funny enough, some of the older Lanz tractors didn’t even have a reverse gear. You’d just have to reverse the engine.
I think that's what it's doing
Thats amazing. This one does have a reverse gear though. You see him use it. He went from backwards to forwards without the engine idling all the way down when turning around on the road.
That's pretty dang funny
@@coolstreetman ya it appears so,funny it has a reverse gear it clearly runs backwards shouldn't need a reverse gear,
Idk much about this design but if thats true then in theory that thing would move as fast backwards as it did forwards.
That's a special mode for when these old tractors needed to reproduce.
these tractors were actually dangerous becouse when they pulled something uphill the engine could reverse rotation and all of a sudden you haul ass downhill
No worries when it does that just slam her in reverse gear and keep going 😂
@@blackturbine : That's not the only reason why they are dangerous. Have you seen how a Bulldog is started? After heating the head with a blowtorch, you lift out the steering wheel and stick it in the flywheel and turn it back and forth by muscle power until you get close to top dead centre and it fires. You need both hands because it is a damn great heavy engine. You can't use a safe crank grip because you don't really know which way its going to run. Then while it is running, you detach the steering wheel and put it back in the steering box. A recipe for getting a hand torn off I would think. There is a common fault that occurs in the transmission. Owners are tempted to leave the engine going while they take a cover off and fix it, as re-starting the engine is such a process.
It seems this particular tractor is still able, at least to run in _reproduction_ mode. Whether it succeeds is another story ... It would need a partner I presume?
@@MrArray1967 : They try and mate with a plow - but there is vary rarely any offspring.
0 rpm must give an enormous mechanical strain on the rod, gear and bearings. Strong engine!
Also I'm pretty sure the oiling system doesn't work at "0 rpm" so definitely not healthy for the engine.
@@creak92 It's a two-stroke so there is no oiling system. And the engine was actually meant to be able to do this 0rpm thing
@@thomasheller629 You can't really compare this engine to your typical small two stroke gasoline that runs on a fuel/oil mix. Air passes through the crankcase as this principle is necessary for scavenging without a blower but fuel gets injected into the cylinder so it doesn't lubricates the bearings. Because of this the Lanz engine has a pretty sophisticated oiling system to pump oil into the main and conrod bearings as well as lubricating the cylinder walls. This system won't work without a pump and without the engine rotating the pump (or Pumps as the Bosch oiler uses multiple plungers) won't rotate as well = no lubrication. The engine absolutely wasn't made to do this 0rpm thing as it has no practical use besides wasting fuel.
@@creak92 Very interesting what you wrote! I think I didn't express myself the right way with saying the 0rpm thing. I actually meant going from forward to backwards movement which the early engines were definetly meant to do because some versions of the Lanz Bulldog had no reverse gear. I don't know about the later versions but some of the earlier ones are still around here and they don't have a reverse gear.
The internals are so beefy they will take it. As far as i know the oil pump works in both directions so it should pump atleast some oil at 0rpm.
The air filter sucks everything in smaller or equal in size to a bumblebee.
And this tractor carries about ~30-50% of it's most essential engine spare parts 😂
Now a days you have to wait in the middle of the field for some John Greede representative mechanic ™ goes and fixes yours with a fucking laptop
@@mr2octavio To be fair, today's stuff works so much better/smoothly, that comparing it to the old stuff and assuming the old ones last more isn't enough to conclude that today we only have crap.
Today you do in a few days the work that took weeks back then.

I love how the exhaust is directly in front of the air intake... Old school EGR system 😂😂😂
Lmao
these kind of tractors were particularly scary when ran uphill, since the engine could rotate so slowly that the force of gravity would reverse the engine rotation, imagine you're a climbing a steep hill and suddenly the tractor "shifts into reverse" at full speed and you're sent flying downhill facing the wrong way and with no brakes to speak of
No, it can't happen. Gravity can't reverse shit. As long you are rolling you can't just reverse the direction
@@MaxMustermann-pu6er if there is a heavy load, and it is running slow enough, a diesel can start running in reverse. I have seen an old caterpillar d2 with a four stroke inline four diesel pulling massive oak logs uphill. the operator didn't know what he was doing, and kept it in third. The immense weight, the too tall a gear, and engine being run almost to the point of stall. The motor started running backwards, exhaust started coming out the intake. And the thing started down the hill, the log chain almost getting caught in the tracks. Luckily he shut the engine off before major damage was done, ha. But in conclusion. Gravity can put such a strain on a diesel that it will try to stall and suddenly reverse it self. It is possibe and I know from experiance that it can happen.
@@phantomcorsair8476 : You made it up as you wrote, didn't you? A Cat D2 is a 4-stroke. Lanz Bulldogs are 2-stroke. Two strokes (Bulldogs, GM/Detroits) can run backwards as described in this video, but 4 stroke (diesels or gas or gasoline) engines, unless deliberately messed about with, cannot. They can't because the fuel injection pump (jerk pump) runs at half crankshaft speed and the fuel-pump piston upstrokes will occur at the end of the normal air intake phase, which in reverse is now the exhaust stroke, due to the fixed valve timing.
Modern Cat engines use hydraulically operated electrically controlled injectors fed by a common high pressure fuel pump. The injection force actually comes from a third pushrod, which in reverse will push after the (now) exhaust stroke, so reverse running isn't possible. In any case the computer won't send the signal at the right time to enable backwards running. This obviously does not apply to a very old (i.e. pre hydraulic operated injection) D2 bulldozer.
It is possible to stall a diesel engine and have it fire back through the intake manifold, but only for one turn as the last charge in a cylinder is fired - the just completed compression stroke acting as a power stroke. It's also possible for an extremely badly worn and very hot engine to run backwards for a short while by firing on lube oil. Such engines are so worn they are very difficult to start when cold due to low compression.
You can, very very rarely, see a 4-stroke diesel running backwards in a workshop - I've seen it myself when I worked for a diesel engine dealer. Diesel engines are configured in the factory for reverse running for marine applications. If a mechanic makes 2 mistakes on a standard engine - installing a LHS starter motor AND times the fuel injection completely wrong, it will run backwards (not very well). This is pretty much a sackable offence, because you have to "try" hard to make such a double mistake, and since the oil pump is running backwards, the bearings will be damaged in seconds.
A more common mistake is to install an RHS starter motor on an LHS motor, or vice versa. The result is that the engine simply will NOT start. It's a trap for apprentices, as they check everything that the tech school taught them, spend a lot of time, and that engine just will not start.
@@keithammleter3824 can you fix my car?
@@mobbdeep615 : Probably, if you bring it to me, and pay me a big enough bribe. Almost anything is fixable if enough money is thrown at it.
PS - I made a silly error in my previous post. A GM/Detroit engine cannot run backwards unless modified, even though it is a 2-stroke, because it is a force induction engine. If you turn it backwards, the blower pulls air out of the cylinders instead of forcing it in,
Back when stuff wasn’t designed to break after so many years
Never mind the spare piston on the back 😂
Lol it’s an 11 litre motor that makes 45 HP the 0.7 litre motor on my motorcycle makes 75 which is only considered average. We have come along way in terms of engineering and efficiency.
@@DMSparky
45 hp but on 630 rpm. Can your motorcycle do that? :-)
@@DMSparky yeah but can you reverse the motor of your bike? Or runn 660rmp or no rpm? Or have this much torque?😂
@@DMSparky the powerband and delivery is all that matters. Your motorcycle engine wouldn't even be able to move the tractor empty.

Like riding a bull.
Well the early Lanz in the 1920 had no reverse it was managed by reversing the engine simple.
Rumba tractor
@@haukbayer4510 Is not so simple because you have to slow the speed of rotation of the engine many times untill you get the right hit to go in reverse or to do something like this 😅
Lol, i never saw an engine running at 0 rpm 😀
Also, the thing looks brand new!
Interesting video 👍
What you forget to mention is the awesome sound that's absolutely impossible to capture. You feel each ignition in your guts. That massive and sudden exhaust from this huge chamber is simply punching you in the bowels. Had the pleasure to see a bulldog in action powering a saw via a belt. incredible contraption and it worked both ways of course.
Reciprocating saw
It sounds like playing big drum
i live in a small town in Germany, where now and then one of these tractors drive on the road, they are so slow, i can't even roll in 1st gear without braking behind them, but sound is really something special, soemtimes i enjoy it and just roll behind one of these.
Well kept Lanz Bulldog tractor. And also well explained about the engine running at "0' rpm. Very sturdy and made for life to run on any fuel a Farmers Tractor.
Totally agree on the sound. One day, I'll get some music sound expert to try and record... possibly using a large diaphragm condenser microphone, the same they use to record e.g. a base drum.

2:47 First mechanical bull?
I was thinking the same haha
Lanz is one of the best tracktors im Germany but After years john deere has buyed the company
Actually helps to explain how the massive marine 2 strokes can go astern without a reverse gear
Do they have reverse pull start on marine engines?
@@vaughntonkin539 I am not sure if the starter can go backwards, but I believe they had to stop and start injection at the right time for that or something along those lines.
@@Jan_372 I know some of the large tugboat diesels, and cruiseship engines can be started in reverse with the starter, not sure about older or smaller ones though.
They had air starters on some detroit diesel boat engines that spin either way if I remember right
Some snowmobiles also reverse by reversing the engine. You just press button and it shuts off and starts again but other direction.
These bulldogs are amazing. We have a few of them in the village I live in (Germany) and it stunns me every time how loud and powerful they are. You can feel every single stroke in your chest
Won't pull the wall out of a house, just takes the whole house with it. I saw one take a 32 ton truck out of the mud, on not much more than tick over.
HP: 45 TQ: YES
well he said 45 hp at 630 rpm - at 630 rpm full output power (i.e. flat out) thats 500 Nm torque. at lower speeds it will be less and less.
It's only 363.6 lb/ft. It's barely anything.
@@tacticalidiot175 well yeah, but it's just ONE cylinder lol
45 hp is actually high power for an old tractor. All of my old tractors from 1963 and earlier had below 30hp but didnt lack power.
@@tacticalidiot175 if 500 NM out of an antique Single Cylinder running at less than 700 rpm is barely anything then I’m the supreme ruler of the universe.

Never had one near something like this but have had many two stroke single cylinder bikes over the years. By far my favorite. Some completely stock over 50 years old and start right up easier than new bikes. Easy going, robust engines that are just happy to run. Love em.
@@LateNightYinzer Well this isn’t a normal 2-Stroke. It uses everything that burns, a so called „Vielstoffmotor“.
You could drive this thing using cooking oil...
@@mullerman1104 If I needed a farm tractor for the post apocalyptic world, a Lanz Bulldog would be it. Runs on enything from dirty used engine oil to alcohol, No need for working oil refinerys to keep that puppy going
My friend has one of these. His, I believe, is older than a 1952. And his you have to pull out the steering wheel, which has a rod on the end of it, stick that rod in the tractor, and rock it back and forth. Once the tractor is running, you have to grab this smaller free-spinning wheel in the center of the steering wheel, pull the steering wheel and rod out while the tractor is running, and put the steering wheel back in it's correct place where is just kind of fits down into the steering column, then you can drive the tractor. And just like this one, you have to let the tractor decide which direction it wants to start off on.
Very cool! This model still has the steering wheel latch but due to safety reasons they were pressed in place and the starting disc you see is used instead. I’d love to get one where the steering wheel is removable!
A lot of people lost their hands and arms doing that! Just imagine to pull off the fast spinning wheel when it had a knob on it....you just had a blink of a second to do that
Lol these engines literally can't stall unless you grow them in top gear tied to a boulder, eland even then they'd fight
Are you sure this thing has gears?? Seems like omitting a gearbox is the best rationale for this bonkers design!
If you did that, you'd be bringing a boulder with you.
@@snigwithasword1284 How is this a bonkers design in any way shape or form?
snigwithasword Yeah it certainly does not appear to have gears
such a two-stroke design can stall and it can be dangerous, imagine puling something heavy up a hill and the piston doesn't make it past TDC, the engine will keep on running but now full power in reverse!
Had a James Sports Captain 125 in the 60's that you could slow the tick over till it almost stopped and it would quitely back fire then run backwards! The look on peoples faces when you wheel spun off backwards was priceless!
2:46 grandpa starting to feel that tractor was a lowrider LMAO
Just when I thought I had seen it all with engines. This comes and completely ruined my day. Back to the books too study up on this beast. BTW....the restoration job on that thing is A+.
"local tractor simply vibing"
one of the best lanz videos ive ever seen
The sound these things make is fantasic! Every year I go to at least one old tractor festival just to hear it. Believe me, in real life it sounds much better than in this movie!
Those big ol' piston engines with their huge rotational cycles are making such a sweet sound...
That thing sounds like a dryer full of bricks
shakes the ground like one to! it is wild in real life... not really loud but like ... bassy goes though bones
I'm shocked it didn't stall out when you put it in gear. The amount of momentum that thing has just rocking backwards has to be huge! And the engine can somehowo overcome this and keep running? Pretty incredible
I remember being next to one of these running when I was a little kid, the sound and movement of it is very intimidating, love it
This thing is friggen cool as all hell!! This is the kinda stuff that earned farming such a hard dangerous job ( and earlier of course ) as someone who worked on h a farm as an operator for 7 years. I couldn’t imagine running something like this on a serious time crunch. Much respect to the old boys!
My first motor bike was 2 stroke. I was told not to let it idle too slowly at traffic lights because it could actually decide to suddenly run in reverse. Letting in the clutch would have then been a nasty surprise! It never happened even though I tried once or twice when my rear was clear.
Old Yamaha dt360’s did this…
They didn’t have the same power when in reverse as they fired after tdc in reverse
Nah this is impossible unless you're talking about direct transmission engines. I drove lots of Vespas (2 stroke single cylinder engine) and never had problems idling at the stoplights
Better then Today's fancy tractors.
We had one that my dad took the steering wheel off to start, was a mission to start in the winter.
A work of art and engineering combined absolutely gorgeous
1:07 Dial goes "Weeee!"
Phenomenal! I remember seeing a Lanz Bulldog in 1958/59 when I was only 5 years old. Never ever seen one again until this video. And YES it was BLUE but the flywheel was not covered. Thank you for sharing.

The earlier Lanz tractors actually didn't have a reverse gear. You had to reverse the engine's running direction to drive backwards XD
@@johnblock6608 lmao

Oh wow, I had this little tractor as a Siku car model when I was a kid! Funny to see a video of the real thing. That bright blue paint with red wheels is forever imprinted in my memory!
How cool is that. Wonderful bit of history there. Thanks.
This is genious design! You dont need reverse, you just reverse the engine, and put it in 1st
It looks like it does have a reverse gear, note at 3:47 he reverses then goes forward without ever stopping or reversing the engine. That concept does make sense though, and he did reverse it without putting it in reverse gear at 4:21 - looks like there's a trick to it though. I've heard of other machines that utilize this characteristic of two-stroke engines to reverse without a reverse gear, such as some ships (direct drive two stroke) or I once saw a rail-speeder (an old track maintinance/inspection vehicle between handcars and those high-rail trucks) with a two-stroke engine that could reverse like that, direct belt drive with no reverse gear. A four-stroke engine could potentially do it as well if the cams were reversed, as I heard was done on some airships (Zepplins) in the 1920s and 30s, and if that Koenisegg Freevalve becomes more common (as I think it likely will even on econoboxes - they're already working on that) it could be done on cars, which could allow omission of the reverse gear.
@@quillmaurer6563 yes, so ships with 2 stroke have air starting, and they can start the engine in both ways, and then dont have neutral. The driveshaft is directly conected to the prop shaft, no cluch or gears
This kind of reminds me of Thomas. this is the coolest piece of machinery I've seen in a while
That‘s the epitome of tractor design in my humble opinion, brilliant!
If you define running without complete engine rotation, then yes, technically speaking, it's running, what a fascinating piece of machinery.

Prank caller: Is your tractor running?
Farmer: 🤔 Yes.... and no.
Prank caller: Oh, well ok then. Have a good day.
I´m from Germany, and I grew up watching these old Lanz Bulldogs, cause we had a Tractor Festival near my hometown where they had a big Lanz community. There are a lot more cool and fascinating things to tell about those machines! You had to heat up the top end of the cylinder when cold starting the engine. You had an oil lamp coming with the Tractor just for that own reason and there was a hole under the brown part of the cylinder head right at the front, you can see it at 0:40. Russian licensed fabricators ( called URSUS) also built those, the older generation always told stories that the russians even had to make a fire under the cylinder head to heat it up. You can´t imagine what it takes to cold start that engine by hand! The guy in the video did it so easy because the engine was hot already. The reason this engine could stay at ´0 RPM´was that the farmers could just let the Lanz run through their breaks or when they had to do other stuff, so the tractor didn´t need much fuel, because it was so hard to start it back up again when it cooled down. They even built so called `Schnellfahrtraktoren´, faster models for the street that could go up to 40-50mph! Circuses where their biggest customers back in the days. The coolest thing I always loved as a kid is that at some rpm the exhaust gases always formed a smoke ring out of the exhaust, you should definitely watch a video of a Lanz doing that! :D
The sound of a Lanz pulling heavy loads is also very scary, cause they appear to be much much louder when pulling stuff. Hope I´m gonna own a Lanz one day.....

2:45 That poor tractor, that poor gearbox.
what gearbox?
@Stolas That's interesting. I was just expecting it to have a gearbox like any other vehicle. This still doesn't look like something you should do to often
@Stolas I think I know what you're getting at - but in fact it does have a gearbox. A big long one that forms the hinder part of the chassis. Between the crankshaft and the differential there are about five geared shafts, all transverse. The driver has one gear lever to select from 3 forward and 1 reverse, plus another to select high or low ratio.

This is insane. I love it. No reverse gear needed
These tractors presented the operators with a few unique challenges
1- Attempting to climb a hill in too high a gear - the tractor lugs down as the torque increases to a stall but it then it does not stop but starts in reverse - too bad about the implement (say harrows) because you just ran over them
2- The lubrication system is only designed to pick up oil when going in the correct rotation
3- Because the engine is not counter balanced the whole tractor continually rocks back and forth when idling in neutral gear - (the engine is still rotating completly and correctly lubricating) but on some of our soil types when wet, (similar to standing on wet sand on the beach and continually wiggling your toes) the tractors will sink and bog itself. All because you left it idling rather than stoping the engine
I have always wanted one! Great video, thank you.
This is so Ridiculous ! I Love It ! Must Be a Super Strong Engine to Withhold the Torque in the Engine while Changing to Forward or Reverse Rotation. I’ve Seen a Single Piston Tractor Before, Just Didn’t Know About all the Cool Features 🤣🤣🤣 thanks for Sharing this #777Slots
