I own seven HRC 216, they are all about 3 or 4 years old. Out of the seven I have one running. I have had problems with the drive shaft coming disconnected causing the self propel not to work. These mowers take a beating but they have become a hassle for me because the nearest honda dealer is about 75 miles away. Has anyone else had problems with the drive shafts? And if so does anyone know if this problem has been fixed?
