I have been passing a JD2010 Crawler Loader while on my drive to work. I have a couple of acres of ground that I have been considering for some light excavation. I mean light, just a little leveling, grading, etc. I want to do it on my own schedule so I prefer not to rent or pay someone else. Also I want to play a little.

I have been researching this crawler primarily because it is not too big and the asking price is, compared to most, low and negotiable. I haven't talked to the owner yet. $3500 OBO It does appear to have been used recently.
I admit to being a novice here, but I am pretty bright and handy with a wrench.
Assuming this is not a parts machine, which it does not appear to be, what kinds of things should I look for and / or avoid?
If it goes forward / backward/ left / right and the loader operates am I fairly certain to get some use out of it?
Hope I am not too naive.
