In my computer I have a directory including pictures of most of the newest Yanmar models. Concerning the US model I know I have downloaded the pictures from a Japanese adds website but it was a long time ago and I don't remember the URL. I think the US model is still on the official Yanmar website http://www.yanmar.co.jp.
Okay, finally! I've been trying to reply to this message for a while now!
The site was most likely PDS (www.pds-global.net). They have a bunch of nice newer low hour tractors. You have to register with them to view details, which I did. Prices are all over the place. They have at least 5 of the AF series on there.
I have no idea how to get one of them over here though. I emailed a distribution yard up north from me about it and they never replied. I am still planning to get a 2210D from Wayne at LMTC if they are still available when I finally am able to bankroll the purchase.
Anyway, the prices are given in yen and I just use the currency calculator built into Google's engine to find the equivalent US price. You can get a darn nice tractor over here (US) for what some of those newer Yannie's cost. Like I said, I don't know how much it would cost to have one shipped over here though you might be able to work out a deal with an importer who buys over there on a regular basis. They might need to fill a load out and may be able to squeeze a tractor on there for you. I don't know how all that stuff works though.
