Before World War II, Dr Ferdinand Porsche's design consultancy crafted several prototype tractors, initially powered by petrol engines and later transitioning to diesel power.

They developed a range of air-cooled engines, spanning one, two, three, and four cylinders, with outputs ranging from 14bhp to 55bhp.

A distinctive feature of Porsche's tractor system, present in all models until production ceased, was the hydraulic coupling between the engine and gearbox.

This innovation allowed for smooth, clutchless gear changes, reducing wear on the transmission components.

Following the war, Porsche was prohibited from manufacturing its own tractors due to restrictions that only allowed companies with pre-war and wartime tractor production experience to do so.

As a result, Porsche licensed its designs to other manufacturers.

In 1954, Mannesmann AG diversified into tractor production by acquiring the rights to Porsche's engines and Allgaier Gmb
