Lanz Bulldog HL

The Lanz Bulldog HL is a simple but sturdy tractor built by Lanz, a German company known for making reliable farm machines. This tractor has a two-wheel drive system, which means it's best suited for flat or gently sloping fields. It has a basic gear transmission with just one forward and one reverse gear, making it easy to operate but limiting its speed options.

The heart of the Bulldog HL is its unique engine. It has only one cylinder, which is quite unusual for tractors. This engine is big, with a displacement of 384.4 cubic inches. It's cooled by liquid in a special tank called a hopper, and it runs on oil instead of regular gas or diesel. The engine can produce 12 horsepower at 420 rpm, which isn't very powerful compared to modern tractors but was enough for many farm tasks when it was made. The simple design of this tractor made it easy to maintain and repair, which was important for farmers who needed a reliable workhorse for their fields.
