Welcome to the Porsche Tractor Register
Whilst they may not be as well known as the company's sports car products, Porsche-Diesel tractors also have a reputation for being every bit as well-engineered, robust and capable of delivering high levels of performance. Between 1956 and 1963 over 125,000 Porsche-Diesel tractors were manufactured.
Porsche's tractor designs were, due to post war restrictions, produced in collaboration with German company Allgaier GmbH and the Austrian company Hofherr Schrantz with both companies used the Porsche engine design. These were known respectively as Allgaier – System Porsche and Hofherr Schrantz – System Porsche.The Register covers all Allgaier – System Porsche and Hofherr Schrantz – System Porsche models.
With its orgins in the early 1930s, the Porsche diesel engine design incorporates a unique air-cooled feature. By the early 1950s Porsche had designed 4 basic models, 1 cyl., 2 cyl., 3 cyl., and 4 cyl. versions, producing between 14 hp to 55 hp. All models have individual and interchangeable cylinders and heads. Always a company to explore new concepts, Porsche designed a 4-wheel drive tractor in 1946. Sadly, although this was ahead of its competitors, it was never put into production,.
Whilst many Porsche-Diesel tractors are owned by enthusiasts, a significant number are still in daily use on farms, smallholdings and plantations around the world. The Register's objective is to maintain and preserve Porsche-Diesel tractors and their unique role in the history of Porsche. It supports owners with technical, repair, maintenance, and restoration matters as well as encouraging them to exchange technical experiences and offer mutual assistance. From time to time we participate in tractor rallies, concourse exhibitions and other events with the aim of promoting and preserving these classic and unique tractors.
As well as being socially active, the Register provides valuable technical support and helpful advice for owners.
