As far as parts for the 4110, I personally don't think it will be much of a problem getting the critical items for a good while. Maybe sheet metal, dash components etc. might be hard to come by in later years. TYM will be a decent source for critical parts for those like mine, and Mitsubishi ought to be able to supply critical parts for some time for theirs. My early 4110 takes the exact same clutch assembly as a Massey-Ferguson, can't remember what the model was. I just hope I'm right - I plan to keep my 4110 for quite a few years yet, it is just the right size etc. I need. And yes - I agree, got to clean the radiator quite often when it's dry but it shows that the airflow for the system is good and the more fins in the core, the better cooling overall. When my temp. gauge gets around 3/4 up, I stop & blow it out, about 3 or 4 solid hours' worth of cutting. Mature sage grass is terrible.
