My 2310 is an '07, now has about 220 hrs. Problems have mostly been relatively minor:
I re-routed some hydraulic hoses and tie-wrapped them into their new positions to prevent chafing, and in one case slipped some plastic hose over a hydraulic hose to protect it;
I've managed to bust off both ROPS lights, repaired them, broke 'em off again :ashamed:.... eventually replaced them both with Kubota lights, which were less expensive and a bit smaller;
Found all 4 mounting bolts for the 2360 blower loose, re-torqued them and haven't had any further issues;
A few obstinate zerk fittings, either replaced them or pulled them off, cleaned & re-installed them;
Added a temp gauge, which I felt was a necessary addition;
Also added a flat-4 connector to the electric chute controls on the blower.
And only two :thumbsup: really significant problems, a broken ground strap/cable (some of these used a cable that was just too short, IMHO) and two hydraulic hoses that let go at 180 hrs or so.
I also recently added a second ground cable on the other side of the engine, and I swear it cranks much faster now; it really acts as though it's got a new battery when starting, but it's still the original.
Overall, it's been a great investment and I'm still very happy with it.
