How to start a Lanz Bulldog

This is a step by step instructional video on starting a Lanz D8516 "N-Model" Bulldog. There are lots of videos on-line of people starting their Puppies but no actual instructions on how to start one. It is quite a process to start these tractors. There are also several places that you can get hurt, or damage your machine if you do it wrong.
I hope this helps new Doggy owners to avoid the pitfalls and get their machine running.

australia is the last place i would expect a lanz bulldog starting tutorial to come from. great video

[@jamesgresham2030]

Actually they were very popular in Australia. There is a wonderful book written by an Australian Lanz dealer. Tractors, Kalashnikovs, and Green Tea. By Ian Johnson. Very interesting look at early tractor years.

A legend in Germany too. 10 liter displacement. 1 cylinder. No valves. No camshaft. No spark plugs, no carburettor. Turns any hydrocarbon mixture into work. A real agricultural horse. Absolutely unique.

[@carltonkeys6205]

😂😂😂😂😂😂😂

[@chrislee2221]

Agree well almost, they were built simple to be run and repaired cheaply, all when Germany was struggling financially, plus these tractors were a big improvement on doing so much by hand or by horse. One thing I do like is that fact the Lanz is still able to do some work and runs like clock unlike the modern stuff in 60 or 70 years from now.

Takes a fraction of the time needed to harness a team.

Greetings from the UK. I have two on steel spade lugs. My late father farmed with Bulldogs in the 1950's, 60's and into the early 70's. They were solid and very cheap to buy after the war as no one wanted to buy anything German. Have yet to start one myself and get it out the barn hence looking at your video for inspiration. Great video.

[@jamesgresham2030]

Hi Mate. Glad you liked the video. As it happens I am on the Isle of Wight at the moment. Great to hear that you have a Puppy stored away. Let me know if I can help you get it going. If it is free and has any compression, we should be able to get it running. There is not much to go wrong.

[@andysutton6436]

A great video. I live in the UK am 77 years old and as a child was able to watch this procedure live many times. Unfortunately the tractor was scrapped before I was old enough to start it myself. However a few years later I purchased a 1902 Hornsby Akroyd 4 nhp blowlamp start that required bouncing the flywheel to start it. Only Stauffer greasers and an oilcan for lubrication. A possible help to start in the right direction. Make sure to put the most effort into turning the flywheel backwards as you alternate the energy input then hopefully it will fire to run predominantly in the right direction. Cheers Andy Ag Eng retired.

[@jamesgresham2030]

Hi Andy. Yep. I've tried bouncing it hard in the reverse direction. But it seems to fire much more strongly in reverse than in forward. I suspect that the governor eccentric is worn in the forward direction and therefore the fuel delivery is retarded when running forward. Some day I will have an expert look at it. I also operate a Rumely oil-pull for our local museum. Now that is interesting o start!!

Thanks for this ! I remember sitting on the front steps of my aunt and uncle’s house in Western Canada watching their son start a Lanz. I was 3 years old an now 68. I remember the steering wheel start but I thought they used a shot shell to fire it. It may have been a newer modern version 😅. Still sticks with me in my mind and is a great memory. I must have been impressed!

I start to discover this fascinating world of old machines not long ago. I´m astonished how durable they are and they are working till this day (some are incredible old) and sometimes literally man eating if you are not carefull enough (that flywheel section was very disturbing what can happen!). It must be quite costly to have such tractor for a farmer - not to mention new parts, but also all the "resources" required for daily use and starting. I´m not that handy with mechanics, but your explanation was very clear and I understood it perfectly! Impressive and thank you :)

[@jamesgresham2030]

Thanks mate. The truth is, these things are actually very simple and easy to keep running. They are built for farmers who only know horses, have very limited tools, and very limited knowledge. They are very very simple machines. But you do need some patience.

A very good and informative video - excellent instructions for starting the engine, and interesting fuels used in a 2 stroke diesel engine.

[@jamesgresham2030]

Just about anything oily will burn in a Lanz. I'm told that melted butter works! This tractor has a second little fuel tank that is sometimes used for starting the tractor with petrol and warming it up. (with the optional coil and spark plug) This tractor was never set up for petrol starting but the tank is still there. Some day I will plumb it in and experiment with other fuels. Canola oil, chip fryer oil etc. If I can rig up a heating mechanism I will try melted butter.

I have also made a video of me demonstrating a 100 year old Blackstone crawler that you might find interesting. I should do a proper video on the Blackstone. It is amazing. fuel injected, dual ignition, overhead valves and air start. The video I made was to help other museum staff start it if they needed to.

[@AnthonyFrancisJones]

@@jamesgresham2030 Thanks, yes I was brought up playing with a Ferguson TE20 tractor and learnt so much about engineering from it. Must look at the Blackstone. My son gets involved in all my KZbin stuff and so gets a great grounding on all things technical/electronic. Yes, well spotted, that was our Rallye! Engine needed replacing so sadly, being so expensive it was cheaper to scrap the aircraft. Shame as I really loved it but it was quirky to fly. I have a video of me flying our 1963 Piper Cherokee if you are interested on my channel. Thanks again, Anthony.

[@jamesgresham2030]

@@AnthonyFrancisJones A hershy bar Cherokee. ! good stuff. The Rallye probably had a Franklin? So I can imagine the issues with the cost of maintenance. I have flown several Rallyes. Fun aeroplane, but quirky as you say. If you get with someone who really knows how to fly them, they are stunningly capable.

[@AnthonyFrancisJones]

@@jamesgresham2030 Yes, loved ours. I have previously done quite a bit of aerobatics so even though not with the Rallye I very quickly got the hang of the fact that it was really forgiving and you could do lots of cool things with it! Slats banging takes a bit of getting used to and the unusual drag curve that would cause it to sink rapidly even if you had good airspeed on approach. Caused one of my group to leave... Nose down, power on and off she went fine! Pain in a tight hanger with that nose wheel as it would dip wings and the like in a tight space! Ours had the Continental O-200-A engine and it was just too pricey to replace. We got our lovely PA28 Cherokee for less than a replacement engine! I think I felt more 'at one' in the Rallye than any other plane I have flown and , being quite small the PA28 is right on the limits of anything I can drag around on the ground and in the hanger but all good fun! You must get airborne again sometime!

The sheer genius of this engine makes me want one for my own!

[@jamesgresham2030]

No cam shaft.s, No push rods, rockers, valves, spark plugs, magnetos, water pumps, carburetors, or even injection pumps. Will run on just about anything oily and produces remarkable torque.

[@jamesgresham2030]

In really cold weather, you would drain the radiator over night and then bring the water to the boil before pouring it back in. Then you poured a spoon full of petrol down a special fitting and that ran onto the piston and sleeve to free up the cold sticky oil. Then it swung into life very easily. Done correctly, it took some time, but they always started even in the most brutal weather.

[@milkman1944]

I really like the old Bulldogs, wish I could see one in person, I think they were available in Canada but never made it to the US. I've watched several starts on KZbin and seems they most time roll it forward bouncing off the compression and really pull it hard to the reverse and it starts in the correct direction most of the time It is quite the ordeal, but beats harnessing and hooking up the horses.

Very good instruction on how to start a Bulldog. You may not know that you have to remove the "compression screw" from the head as the air pressure may prevent the oil from oiling the piston and gudgeon when you prime it.

[@jamesgresham2030]

As you wind the fly wheel around to the correct spot for pre piling the engine does start to come up on compression. Perhaps because this engine is old and worn, I can get to the right spot without having to pull the plug. A new tight engine might be harder though. The manual does suggest that you might have to pull the plug if I remember correctly. Thanks for you comment though. Glad you liked the video. All done in one take, hence the occasional slightly incorrect commentary.

So...if you were to be pulling an implement, and the tractor bogged down enough, it could potentially switch itself to running in reverse, right?

[@jamesgresham2030]

yep. It is a known challenge. Running over you own plough. Competition tractor pulling guys will let it stall and take off backwards then they jump on the clutch select, reverse and drive away forward. It gets really confusing.

[@wilfredmancy]

The engine is much weaker running backwards, I suspect the injection timing is in the wrong place in reverse, also in reverse the governor weights are leading rather than trailing and would be tending to work against bringing the eccentric into maximum stroke I think. About 2:19 can be seen the circular governor housing bolted to the inside of the flywheel. The two springs for the two weights are visible. Just above his hand is the adjusting bolt for the high idle weight with its two locknuts. I worked these tractors for years plowing, sowing, harvesting, pushing up logs and mallee scrub and tank sinking, the engine running backwards and hence the tractor is a novelty or party trick rather than a preferred practice.

Hi James nice video but i think the book says 180 cranks of the oil pump at roughly 1 every second

[@jamesgresham2030]

160 to 180 slow cranks according to my book. I’m not sure if pre-oiling or purging is the limiting factor. Modern oil has much better oil clinging than old oils so preoiling is probably not that big an issue. But scavenging the sump very important. Particularly if someone left the fuel on for any length of time. There was lots of extra things I wanted to say but the video was getting very long.
