I have a 2004 6415 which varies rpm. The tractor since new, and now with only 260 hrs, has varied rpms. At first it was using the governor when mowing. RPMs could drop to 1200 from 2200. Now it even does it at idle. JD said bad fuel and I have been through 3 sets of filters, then they said minute holes in bad fuel hoses. They are at a loss to explain. Does anyone know?
