Why does John Deere have so combine models that are only available in foreign countries. There are so many combine models like the W series, most of the T series, and the S400 series that are only available in other countries. Meanwhile the only combines available for US/Canada are the S700 series, the X9 series, and the T670. Also, a lot of these foreign combines series include compact designs that could be popular if sold in US/Canada markets. This isn't a new thing either. Back in the 1970s-1990s, there were entirely different combine models for European markets.
