Jon Hagen I think is who told me this but when I was in Hawaii for a while the best dealer in the US is in Hawaii. I needed a few part that I thought wouldn't be this side of Tokyo and beleive it or not they had what I needed. The guy's english sucks; he's got a severe Japaneese accent but sure as hell know his business with them little tractors. I was told that parts including freight was cheaper than anybody on the mainland too. Freight coming back this direction is cheap and going 4X.
