If the hour meter stopped at 485, you have no way of knowing how many true hours it has. Determining the manufacuture date will help. 10K may be a good price for all of that, depending on the shape it's in. It's a second owner, and you have no way of knowing how it was maintained. Look for evidence of good greasing at all the zerks and bushings on the tractor, loader and backhoe. Check to make sure there isn't too much wear on those bushings.
Assure that the 3pt hitch raises and lowers properly with an implement on and off. Run the tractor for at least 30 minutes, any overheating should show up. Look at the radiator to see that it has been kept cleaned out, check the fins.
Look for leaks anywhere. Also look for eveidence of any rewelds that would indicate breaks. Make sure the shuttle shift is sturdy and not too hard to shift (you have to stop completely before shifting with this mechanical type shuttle), and that the steering wheel is tight.
Any problems you find will bring the price down accordingly. If you know someone that knows tractors, try to take him/her with you to inspect the tractor.
