Prof. Dr. F. Porsche produced three prototype tractors in 1934, all equipped with gasoline engines. The Porsche diesel engine design with its unique air-cooled feature was just not quite ready for production at that time. Through numerous tests this design let to a fully developed air-cooled diesel engine with a power range from 14 hp to 55 hp. By the early 1950’s Prof. Dr. F. Porsche had designed 4 basic models, 1 cyl., 2 cyl., 3 cyl., and 4 cyl. versions, all have individual and interchangeable cylinders and heads. Another interesting fact is, that Prof. Dr. F. Porsche also had a 4-wheel drive tractor on the drawing board as early as 1946. Obviously, way ahead of everyone else.
Prej ste govorili kdo je prvi izdelal traktor z sprednjim pogonom. Preberite zadnja dva staveka malo više pa boste zvedeli kdo je prvi razmišljal o tem pa zaradi smrti ni mogel dokončati projekta. Eden je bil očitno izdelan ni pa mi še uspelo izvedeti ali je to ogrinalna izdelava ali si je kdo to sam izdelal. Pa tudi sprednji kardan so imeli ti traktorji.
