Short documentaries about the restoration of a one-cylinder Lanz Bulldog D 9506 tractor from the 1940’s, and a similar Ursus C-45 tractor from the 1950’s. You will see the results of the works on the vintage tractors, including the first start of their engines after 40 years.
Both the German Heinrich Lanz AG and the Polish Ursus factory produced the D9506 and C-45 / C-451 in many very different versions. The first post-war C-45s were technically faithful copies of the pre-war D9506 in its straightforward version. The simple C45 equipment changed significantly with the later Ursus C-451 tractor, which is a very well-equipped version with a Bosch swing starter, 12V electrical installation, hydraulic jack, etc. In general, Lanz Bulldog tractors are made of parts of a higher quality, but Ursus improved the production quality over time, especially of the engine. For example, the Ursus factory perfected the production of engine heads, which allowed the engine to be tuned with a crazy 100% power increase. To summarize, the Ursus C-45 / C-451 and Lanz Bulldog D-9506 tractors are so identical in design that almost all parts can be moved between them (the gearbox is the only big exception).
The vibrations must be off the wall all in that tractor I have seen the cylinder of it being the cylinder of it it's the size of a ship's engine cylinder in cylinder it's huge and I'm and I imagine there's a lot of up-and-down force on the frame I've actually seen in low RPM's the tractor actually trying to bounce up-and-down
Klasse Arbeit Jörg. Hat richtig Spaß gemacht zuzusehen. Hoffentlich sehen wir uns Recht bald einmal. Liebe Grüße aus Orferode an Euch alle (und auch an den kleinen F15). Bis bald einmal....
