Hey all, we have a 2007 t-300 with appx 1600 hours on it. Around 900 hours, the left side track lugs broke where the sprocket meshed with the tracks. Bobcat said it was worn sprockets and replaced them claiming they were a "wear item" and not subject to warranty. Have any of yall experienced this? What is the typical track life hour wise (I know this depends on conditions etc)? What is the typical sprcket design life? Bobcat has not told us these figures. The new sprockets now 700 hours old are starting to wear and cup again. It would be nice to have some data to backup when it comes time to replace them again if need be. Thanks
