Photos from Keystone--Lanz Bulldog

RedMF40 · Apr 3, 2021

I'll try this again. Posting photos has not been working out so well lately---after two pics the whole thing freezes up. And those 2 photos take a long time to upload.

Lanz Bulldog, employing the very latest in "hot bulb" technology. The proud owner would heat something with a blowtorch, then spend some time with that steering wheel attached to the side. After he managed to get it started, I'm sure he never wanted to shut it off again. I believe this was a single-cylinder engine.

What is special about this museum is that it features many unusual tractors I've only read about in different publications. Never seen them in person.

That is a piece of art!

Wow! That's sharp.

We saw some Lantz Bulldogs at the Heritage Park show near Forest City, IA a few years ago. Neat looking critters.

Never seen one in person, but have watched many videos of the cantankerous starting procedure!

From what I've seen, they have no reverse, but the engine will run either way. To reverse it the engine has to be stopped and reversed.

But a healthy engine with an experienced operator can be reversed by shutting it down and catching it just right on the rebound off the last compression stroke and it will refire going the opposite direction!

The very first Bulldog (1923) did not have the reverse but all later ones had the reverse gear, If the engines ran backwards then the lubrication system did not work, or only worked poorly. On starting, once the bulb was hot (heated with blow-torch), the engine was rocked backwards (with steering wheel attached to flywheel, towards top dead-centre, whereupon, if you were lucky it fired and rotated back in the right direction, if unlucky and you got beyond top dead-centre and it fired then the engine was running in reverse and you cut the fuel so that it almost stalled, then gave it fuel just as it approached top dead-centre again and then hopefully ran in the right direction. It is a semi-diesel with about a 4.5:1 compression ratio. A diesel engine needs at least 14:1 compression ratio.

That looks like the one in the lobby.

Had relatives and other people I knew that operated these. If parked running on wet ground they could hammer the front wheels into the mud. Former neighbour had a Field Marshall, same design English made. It was started using a shotgun cartridge with no shot in it. It didn't have turning
brakes so was difficult to turn. Have seen them run at antique shows, it is interesting how they comment how smooth my Farmal H runs compared to the one luggers.

That tractor is a real work of art. Someone put a lot of talent and time into making it look that good.

Great picture of a wonderful tractor.
