The 12-24 Big Bull is a small tractor that was also an experiment in tricycle design — it has steel wheels of three different sizes. Built for ploughing and belt work, it ran on gasoline or kerosene. Its cross-mounted engine enabled the power to be transferred more directly to the wheels. The 12-24 Big Bull was popular at first because of its affordability, but soon lost favour because it was unsafe and often got stuck in the field.
