International Harvester-Germany was a subsidiary of the International Harvester Co. of Rock island, Illinois, USA. The factory in Neuss manufacturered agricultural and construction machinery. It was one of the two most important American tractor factories in Germany, the other being John Deere‘s in Mannheim, in the 1950s to '80s.
The reason for International Harvester to build tractors in Germany was simple. It was cheaper to build machinery directly in continental Europe than it was to import. The factory at Neuss was International's second attempt to manufacture in Germany. The first time was just before War 2 World War 2, but in 1941, after the US declared war, they were kicked out. With the end of the War and the return of International, new models soon arrived, like the Farmall 100 and International 650. With the economic slug of the '80s, Case bought IH in 1985 and production of International-branded machinery stopped in 1986.
