FYI...
It's two year bumper to bumper, plus another year powertrain. (So 3 years total). New for 2014/15 Massey models have updated to a 5 year warranty.
Also, I'm not sure if this will be your only tractor, but if so, I would highly recommend getting a loader. Now naturally we all use our machines a bit differently, but I wouldn't bother even having a tractor if it didn't have a loader (if I only had 1 tractor).
Finally, unless you're saving a ridiculous amount of money, I'd have a hard time buying a rental return with 590 hrs. I use my tractor a lot; more than most people seem to on this forum... And I've only put 450 hrs on in the last 14 months. I know exactly what was done with it, both workload, and maintenance.
It would be kinda like marrying a prostitute... Constantly wondering what part of her shady or overused past is going to cause me grief first.
