A restaurated, fully functional Lanz Bulldog tractor, built in the ´30s or 40´s by the company Lanz. Back then the term Bulldog was the colloquial name for tractors in southern Germany, especially in Bavaria where they still use this term. The single-cylinder hot bulb engine was capable of running with various liquid fuels, including crude oil. This photo was taken on Aug 9th, 2019 in Straubing, Germany.
