You can pick up a genuine vintage Porsche in working order for less than $20,000 and use it to plow the field – if it’s a Porsche tractor. Yep, Porsche tractors were manufactured between 1950 and 1963.
And, according to Porsche-Diesel North American Registry,
Fully concourse restored Porsche-Diesel tractors are being traded in the $15 – 20,000 range, however, un-restored examples in good running condition usually sell between $5,000 and $6,000.
Because tractor production was limited to companies that built tractors before and during WWII were allowed to build tractors after WWII, Porsche licensed its design to the German company Allgaier GmbH and the Austrian company Hofherr Schrantz. These two companies used the Porsche engine design and called their tractor: Allgaier – System Porsche and Hofherr Schrantz – System Porsche. By 1956 Mannesmann AG decided to get into the tractor business and bought the license for the Porsche diesel engine design and the Allgaier tractor design. Over 125,000 Porsche tractors were manufactured between 1956 and 1963. at the old Zeppelin factory in Friedrichshafen-Manzell, Germany.1
