• Desirable Junior variant • Restored to a high standard • The most affordable route to Porsche ownership Dr Ferdinand Porsche's design consultancy built a handful of prototype tractors prior to WW2, the first of which were powered by petrol engines, before turning to diesel power, eventually developing a series of one-, two-, three- and four-cylinder air-cooled engines ranging in output from 14 to 55bhp.

An unusual feature of Porsche's tractor system (fitted to all models right up to the end of production) was its hydraulic coupling between engine and gearbox, which permitted smooth clutch-less gear changes and thus reduced wear on the transmission components.

After the war's end Porsche was barred from producing its own tractors (only companies that had been making tractors prior to and during the war were permitted to do so) and thus was forced to license its designs to other manufacturers.
