I looked at a used 2022 Bad Boy zt Elite 48” with kohler engine today. Owner says it had about 15 hours but the hour meter died at 10 hours. He said he had is serviced at 10 hours. He asked 4,400 but I got him down to 3,800. I’m contemplating buying it. The machine looked like it had more than 15 hours, filter was a little dirty especially after only five hours since service. Is the hour meter a common issue? And if I was to plug a new one in would it show all the hours that the mower actually has on it?
