I have nothing more to add to this. Kenmac pretty much covered it. Frederics is the only one that can import yanmars i beleive and can now sell Grey YM's on ebay as he is allowed too. Hoye did not get sued out of the business somehow, thats thier business though, maybe cause he no longer sells tractors just parts??
There are other dealers that sell YM refurbs, but they are tractors from fredericks. I am not sure what old inventory that was laying around from VN places what happened to it, bought back, forfeited?
But any tractor dealer can still sell a grey YM yanmar refurbed in Vietnam that was in this country prior to the lawsuit rulling. There thousands in the country (ever seen the pics of VN1 tractor yard in ATL or wherever it was or the other one in TX there were thousands on the yard for the pic!!!) so my guess is that ones will continue to show up on lots as trades for other tractors to be resold. You would be suprised how many folks think they NEED a tractor on thier 3 acres and they figure out a ZT mower is way faster to mow with or turn so they have the tractor to sit for the few times a year they need the loader or boxblade. Or you have all the hobby farmers city guys that buy one and then realize its tough on your body to bounce around on a tractor for hours in the heat and just let it sit most of the year.
I bought a VN tractor a YM2000. I think i have made out ok, it has a bit of blowby now out of the tube but i have put 150 hours on it, which is nothing for a tractor yes but we dont know it anything or nothing was done to the motor? It is still strong and does not use any oil that i can tell in a 50 hour oil change. The hydro works fine, now after 4 years or so one of the arms is developing a leak at it but the tractor is 35 years old. I got a radiator and voltage regulator while it was under warrenty and they had to swap my 3pt system on the top of the trans. It had a bad vavle i beleive and was overheating the fluid to the point i would loose lift strength. If you have looked at these tractors this will make sense, its the top part of the trans but contains all the lift arms, lift piston, and valve.
I have replaced a rear axle seal that started leaking after 3 years, and replaced the oring on the three point lift, which helped it a bit from leaking down but came to find out the valve is leaking just ever so slightly, and even new orings in it did nothing. The guys at Hoye said dont worry about it and to just leave it but i am one of those that likes every thing to work right. It causes no issues running it but when its stopped the impement will slowly leak down, which an implement should not be left in the air anyway but still it should hold it forever basically.
I know i have rambled but i am giving you a rundown of what i have done to mine since i had it. Oh and the hour meter on mine turns an hour for every hour it runs at 2400rpm i seldom run at that speed so if you run lower your tractor actually has more clock hours on it than the meter says. For example if i bushhog at like 1700 rpms in light grass i am not lugging my tractor for the load i am putting on it but i can cut for like 1.5 hours on your watch but only turn around 1 on the gauge so i really have way more than the stated hours on my tractor. Like when i use the box blade i am really just putting around maybe 1500 rpms if really digging the tines in but usually just barely over idle as i more small amounts of material around.
