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.

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.

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.

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 😅

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,

Never mind the spare piston on the back 😂

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.

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.

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...

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

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!

Those big ol' piston engines with their huge rotational cycles are making such a sweet sound...

shakes the ground like one to! it is wild in real life... not really loud but like ... bassy goes though bones

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

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.

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

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

They're credited with being responsible for the Luftwaffe fighter aircraft being able to continue to operate from their mid-winter Russian located air bases. Every other engine would freeze up in those -50°C conditions but the Lanz Bulldog would always start because its single cylinder could be heated with a blow torch.
