Lanz Bulldog – kit made from LEGO® bricks

The Lanz Bulldog from Heinrich Lanz AG in Mannheim was a big hit at the time. The Bulldog – doesn't it look a little like its animal counterpart from the front? – became a colloquial generic name for farm tractors from other manufacturers as well.

The Lanz Bulldog D 1506, the top model in the family of field air Bulldogs, was produced from 1937 to 1955. The engine was as simple as it was ingenious: its single-cylinder, two-stroke medium-pressure engine with glow plug ignition consumed pretty much everything from cheap crude oil to domestic vegetable oil. The glow plug era ended in the 1950s with the introduction of the much more economical diesel engines.

If you come across a Lanz Bulldog in the wild these days, you can assume that it is fast approaching retirement age. In 1956, Heinrich Lanz AG was taken over by the US agricultural machinery manufacturer John Deere, which stopped using the brand and company name "Lanz" in 1967.
