The history of Bührer
Bührer was a Swiss tractor works that outlived its own tractors, and still has the parts on the shelf.
Fritz Bührer (1896–1974) set up on his own account in 1921, renting a workshop at Burgdorf. In 1927–29 he took on a Ford dealership for cars, lorries and tractors at Frauenfeld, and in 1929 the first Bührer tractor appeared, with a mower bar driven from the side of the machine.
On 1 September 1936 he took over Jakob Reimann's business at Bäretswil along with its existing workforce, and in 1939 bought the empty factory of the former Maschinenfabrik AG Hinwil. The move from Bäretswil to Hinwil was complete by early 1940.
The Bührer tractor became something of a showpiece of Swiss agricultural engineering. Countless special builds and prototypes left the works, including machines for Zurich airport, for the army and for many other businesses. During the Second World War Bührer built wood-gas tractors as other makers did, and after it came the firm's best years — the most successful model of all being the Vielzwecktraktor, at around 7,000 built. The Bührer Tractospeed transmission was presented in 1964, and the firm became a joint-stock company the same year.
Then it followed the pattern of a good many engineering pioneers' companies. Bührer was out of his depth on the commercial side and missed the structural changes the business needed. He had to sell to the Rapid group at Dietikon in 1973, and died on 14 September 1974. Tractor production ended in 1978 after 22,624 machines in all, and the factory was taken over by the Mägerle family on 1 January 1979.
Bührer Traktorenfabrik AG is now a workshop, servicing, repairing, converting and overhauling tractors and farm machinery of every make, and holding a large stock of parts for Bührer tractors and for ZF and Schindler axles. Around 10,000 Bührer tractors are still at work around the world, with some 2,000 more driven only for shows.
