the traffic shows more about a sites design and search engine placement than it does anything to do with the product. Another site I work on would lead you to believe that TYM owns 70% of the market. Kubota, New Holland and Deere make up just shy of 90% by most estimates. That leaves the balance for everyone else. Its hard to make any real judgments from there as the other brands are very regional. Mahindra is bigger in the south, while Kioti seems to do better in New England. As of two years ago Daedong had posted on their website that they sold 8000 tractors/year in the US. The market is around 250,000 total units, thats about 3%. With around 220 dealers thats 40-50 per dealer average. Thats tough.
As for who is growing. I read a report from Chase (I think, it was one of the big banks) last week on the agribusiness industry and according to that Deere and Kubota are adding share. The rest are loosing. Granted, that report was almost totally focused on Agco, Deere and CNH.
Bottom line, no one really knows. Industry folks like myself wonder these things too.
