My TN65 is a little different then the 75 but I have owned it new since 1999 and it has over 1100 hours currently. You already know how I use mine from your other post but I had a few problems when the TN was first released here and NH took care of them. Those problems are no longer an issue. Other then my first year issues the only problem I have had (that I can remember) is a Neutral Safety Switch (commonly referred to as a NSS on here) failed. It is a rather cheap part to replace, take out two screws and remove the electrical connecting plug and the old one is out, put the new one in and your on your way again. The only down side is the one that died on me could only be accessed (easily) by removing the left rear tire which can be dangerous when loaded but generally is scarier to think about then to actually do. If you ever have this issue with any loaded tractor tire just jack up the back and block the axle so the weight is off the tire but the tire is on the ground still. Remove the lugs and roll it over to a post against the wall and let it lean against the post. If you have a helper this is a rather simple and uneventful chore.
New Holland has been updating and modifying the TN series since they were released and as problems come up they adapt the tractor to address them. Most of the old problems on here should not be a problem on a new model but I do not have a new one to know how it holds up.
