See a large collection of the German built Lanz Bulldog tractors being demonstrated. The models range from the late 20's to the 50's. The unique machines burn on almost any kind of fuel oil, even crude oil. You can see one of the first models built from 1921 and a very rare 12 horsepower Lanz Bulldog which at the time of our visit was said to be worth around $50,000. Like all the models from the 20's they had no reverse gear, so to back up the tractor the operator would crank the engine backward
