2200 hours is a lot for a garden tractor, especially if it was run hard and put away wet.
If you insist on green tractors, the JD 318, 322 and 332 are right up your alley. My Cub Cadet 3000 series technically does satisfy all of your requirements but it's on the smaller end and the attachments can be rare and expensive. The older Cub Cadet Supers would be a good possibility, like a 2086 or 2182.
Personally if I ever have issues with my Cub Cadet 3000 that are beyond what I want to repair, I'm going to swap it for a Kubota BX. They are only a touch bigger but a lot more capable.
Well, its a tough spot to find a fit for. Its also not as much a goal of being green, but in the case of that 455, i really like the engine they used. It had a 22hp 3 cyl yanmar diesel, liquid cooled, horizontal shaft, and its not that bs rating you see when an intek is called a similar hp.
Reputation and anecdotes on those old yanmars was absurd if you keep up with them properly. At any rate I'd feel safe with a well kept version being good well into the 5,6,7000 range. I haven't had one of those 3 cyl yanmars since the late 90s, but it was a great engine.
The hydrostatic is claimed around 5,000 hour life for the 455s... do I believe it? I dunno. But I believe it's a lot higher than the average lawn tractor.
I did look at the 332s, but, as hard as a JD40 loader is to find, a original 320 (not the newer 320R stuff) loader I havent even seen in person. I'm not into the Johnny buckets or Buford buckets for the purposes and work to deal with here. Lift height and weight would be a problem. I'm most familiar with the small JD loaders, but, if I can find something else I'll be considering it on a case by case basis - exception being, of course, not spending 6 months hunting rare implements then spending tons of time working on them just due to health constraints.
The old JD40 loader at least could have the cylinders shimmed and then could reach 1200-1300 PSI buying the lifting capacity easily into the range of more than you should use. Thats newer x7 series pressures and fairly capable for what it is. Tough on the front ends, but, if you didnt constantly use it like that things worked out OK.
The more i think on it though, id be very skeptical and probably wouldn't buy something of the age with a gas engine unless there was a known source component to it all - too much questionability with the fuel usage and people not sticking ethanol free these days. There's always exceptions.
I had looked at bx-series at our prior properties some years ago, and, at the time they were a good value for what you got, especially with their aggressive financing.
One thing that is a sticking point though is weight. Even the light BX tractors outweigh say the 455 by 400 pounds before implements. Being where we are, the soils stink for weight bearing. Big difference between 900# and 1300# if it's been raining lately.
That kind of steers me towards 'the king of all garden tractors' category over a true SCUT.
