- There are basically two Lanz Bulldog hot bulb types. The small ones with 4.7 litres capacity (291 cui, 20-25 hp) and the big ones with 10.3 Litres (630 cui, 35-55 hp).
- Although they have a very low compression ratio, you will never start them by turning the crankshaft over TDC.
- For starting, you rock the crankshaft against the regular turning direction into the compression. It will jump back forwards and ignite (and start to run in right directon).
- Starting a Lanz Bulldog is very dangerous, if you are drunk or you don't know what you're doing or it's a tractor you're not familliar with.
- The steering wheel with its shaft won't release automatically when the engine starts up. You have to grab a small free spinning knob at the center of the steering wheel. Have your steering shaft always greased well!
- If you want to brake your crankshaft or bend your conrod, you can pull start a Lanz Bulldog.
- A Lanz Bulldog can start an run in both directions, which is harmless for the engine. A pro can switch the running direction by using the injection pump hand lever.
- To avoid fire hazards, Lanz offered a gas start option, includig a spark plug and a buzzcoil. You could start up the engine on gas and after warming up you could switch over to Diesel fuel. Nevertheless, all Lanz Bulldog hot bulb tractors came with a blow torch from the factory.
- Lanz offered an electric starter. That starter did not turn the crankshaft over TDC, it rocked the crankshaft back and forth like you do with the steering wheel by hand.
- Lanz tractors have always been single cylinder two stroke engines.
- Lanz hot bulb engine can run on almost every fuel you can imagine. Even on hot liquid butter and tar!
- Lanz engines have never been started with a shotgun shell like Field Marshalls.
- John Deere did not buy the Lanz company because of this engine. They bought Lanz because they wanted a large, cheap factory in Europe. Lanz suffered in the mid-1950 from bad sales figures. All farmers wanted to get rid of the rude running Lanz Bulldogs and wanted the new smooth running Hanomags, MCormicks and Ferguson. Traditional Lanz owners HATED the all-new John Deere tractors.
- Did I forget something?
- Yes. Lanz Bulldogs are some of the coolest things you could ever drive with!
