Movie showing a two-stroke engine with one huge piston moving horizontally

[DarekFFM]

Hi old-timer fans,

If you are interested in watching an old two-stroke engine with one huge piston moving horizontally (diameter of 9 inches / 225 mm), which was seen in some tractors in the 1940' (e.g. Lanz Bulldog, Pampa, Ursus C-45), please see my recent amateur documentary on YouTube:

If you like it, you may also be interested in two others:

Enjoy,
Darek, a proud owner of a Lanz Bulldog D 9506

Now that was an interesting watch! I would, however, suggest some ventilation for your workshop!. It'd be easier to see some of the start up scenes!

Out of curiosity, what was used to preheat the cylinder originally?
