Those old, literally 'heavy metal' machines like tractors and construction vehicles have a stunning repertoire of shapes, massive appearance and rich material.

I love that kind of mechanic stuff and so my new personal hard surface project is this ancestor of modern tractors: A german Lanz Bulldog "Ackerluft" from 1949.

Here are some first renders, I'm still working on all details and the complete back part of the vehicle. Later on are a substance painter work step and the design of 3 subtypes for different usecases in planning.
I will post the further WIP here...
