I have a 2008 tiger cub that has approx 4-500 hrs on it (hr meter died at 70hrs). Oil changes and lubrications have always been done at recommended intervals (by me). Have had no problems. Getting ready to do the spring "get her ready" routine. Belts show no sign of wear (reckon I need to change them anyway?). What about blade shaft bearings? I have never replaced anything on this mower with the exception of air and fuel filters. I suppose it would be a good idea to replace the hydraulic fluid and filter also. BTW, awesome forum, wish I would have found this sooner.
