Lanz Bulldog HP

The Lanz Bulldog HP is a single-cylinder, oil-fueled tractor known for its unique and rugged design characteristic of early 20th-century engineering. This model houses a 15 hp engine that operates at a notably low 500 rated RPM, with an engine displacement of 384.4 cubic inches. The engine's dimensions are expansive, with a 7.48-inch bore and 8.661-inch stroke, contributing to its capability to generate torque at low speeds. The Bulldog HP is built with a simple transmission system consisting of 1 forward gear and 1 reverse gear, highlighting the tractor's intent for straightforward, heavy-pulling tasks rather than speed or variety in gearing. The liquid (hopper)-cooling system is indicative of the era's technology and is quite different from modern liquid cooling systems. Despite its age, the Lanz Bulldog HP maintains an iconic status among collectors and enthusiasts for its durability and distinctive operation sound. The tractor's four-wheel-drive chassis implies a solid performance in rugged conditions, making it a piece of agricultural history as well as a symbol of early mechanical ingenuity.
