Lanz Bulldog

The Lanz Bulldog was one of the most popular German tractors, with over 220,000 of them produced in its long production life.

The Bulldog engine was installed horizontally, with the ignition device – the hot bulb – facing forward.

[3] This had a large bed over the front wheels, for transporting cargo over ground unsuitable for a trailer.

Some of these examples are: "Le Percheron" was a licensed copy of the 25 HP hot-bulb Bulldog, built by Société Nationale de Construction Aeronautic du Centre (SNCAC) at Colombe in France from about 1939.

The KL Bulldog was produced by Kelly & Lewis of Springvale, Victoria, Australia from 1948 to December 1952.

In 1951 a copy of the 55 HP Bulldog was produced by Industrias Aeronáuticas y Mecánicas del Estado in Argentina.

From 1955 the tractor was produced by Dirección Nacional de Fabricaciones e Investigaciones Aeronáuticas and the badge was changed to DINFIA.

Some of these examples are the SF Vierzon from France, the Landini tractor from Italy, and the HSCS from Hungary.
