The Porsche tractor design included a hydraulic coupling between engine and transmission; this distinctive feature of Porsche-Diesel engines was used in tractors up to the last model produced in 1963. Engineers in the 1930s 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 WW2, 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. These two companies used the Porsche engine design and called their tractors Allgaier System Porsche and Hofherr Schrantz System Porsche respectively.
The tractor on offer today is one of the rarest of all the Porsche tractors; this single cylinder machine must also be one of the most beautifully restored examples. It has part of a large tractor collection for the last fifteen years and it was restored recently by a Porsche car expert. It is seldom such a wonderful example comes to the market. Not to be missed.
