Porsche's interest in the manufacture of tractors began in 1934 and continued until the early sixties. PorscheTractors (a member of the PurelyPorsche family of web sites) provides details and photographs of the tractors of this era.
You can discover the specification, details, driving impressions and more for every road-going Porsche car at PorscheArchive.
A fully researched directory of Porsche Suppliers and Resources is available at PorscheFile (one each for UK, US, Australia and Germany).
Generic information on diesel tractors can be found here and information on farming equipment here.
