I bought a used T3000 or 3200, depends which side of the mower you look at. Its a Husky/AYP built, 42", all black, electric PTO engagement and K46 hydro trans. I bought it with 120 hours back in the fall of 2016. I have about 206 hours now. Its not a high end mower by any means. I find the chassis flexes more than that guy who only works out his biceps at the gym. But.. other than that, it has been a great mower.
It has the 22hp Briggs Platinum, which has been absolutely flawless so far. No shortage of power, starts easy and never misses a beat.
I read the usual horror stories about Tuff Torq K46's dying early deaths, so I changed the oil out with some 5w50. It too has not missed a beat.
The deck, belts, spindles etc are all running great and I have yet to change them. Other than plugs and an oil change and cleaning the deck, no maintenance needed. I guess it needs a new battery though (2014 build date)
I changed the oil around the 150 hour mark, used cheap PYB 5w30 and a Fram TG 3616 (or 3600, which ever is the shorter one). It doesn't burn or leak oil and it is barely dark in color now.
I was under no illusion that I was buying a high end mower but have been surprised how reliable it has been and the quality of cut it does. If I had to do it all over again, I would look at the same thing but maybe a bigger deck.
