I know I will get a million different opinions and that is great! However I would also like some feedback as to my statement/question. I run a part time lawn care business. My first ZTR did not have an hrs meter but I ran it for years and probably had about 2500hrs on it when I sold it. However, the last summer I spent tons of money repairing it but never got it back. So at what point should you sell a ZTR assuming you don't want to do a ton of work? Or you can approach the question as when do ZTRs generally start having major issues assuming that they have been well maintained and only run about 3hrs per day? I am thinking of selling mine around 1200-1500hrs.
