And you prob'ly believe that a 21 year old tractor only has a thousand hours on it. Right? Mebe so but I'd look hard at it.
Not knowing how hard you plan to work it and what you plan to do, it's hard to know what to recommend and I won't. I do however hear good things about Kubota and would likely have bought one but.........I kept procrastinating, did I really need a new tractor. Well yeah 'cause I really, really needed a front loader and the ancient Ford 8N I've been drivin' forever doesn't even have live hydraulics. I liked John Deere (mostly the prices) so well I never visited them even though I can see the local dealership from my house. I did do a lot of internet research and you should too. I used this site a lot. http://www.tractordata.com
And this one www.tractorhouse.com. I joined a bunch of tractor forums and searched 'em all.
In the end I bought a 2013 New Holland T1510 4WD with a NH front loader and a rear tiller that was being repossessed. It had about 700 hours on it and I know what kind of hours most of 'em were. I paid exactly $10,000 for it. The New Holland dealer where the tractor was originally purchased is only about 15 miles down the highway from me. Look around, don't get in a hurry, do your research, and ask questions as you are. There's a deal out there waiting for you.
