The Porsche tractor design included a hydraulic coupling between engine and transmission; this distinctive feature of Porsche-Diesel engines was used in tractors until the last model produced in 1963. Engineers in the 1930’s believed that farmers in those days were not able to handle a clutch properly when shifting gears. Prof. Dr. F. Porsche produced three prototype tractors in 1934, all equipped with petrol engines. The Porsche diesel engine with its unique air-cooled feature was not quite ready for production. After WWII only companies in Germany who were producing farm tractors during and prior to the war were allowed to continue producing those tractors. Since Porsche was not one of these companies, it signed licensing agreements with the German company Allgaier GmbH and the Austrian company Hofherr Schrantz.
