Hola everybody, Does anyone know if JD or anyone else makes mulching blades to fit on a JD GS30? It's 36" w/2 18.5 inch blades (overlap). The deal is that the blades have a hole that is not just a hole, it's more of a hole with wings (0) so that this fits into the spindle that has the same pattern, but solid that it slides into. I'm not sure if all other JD mowers are like that, but the blades are not easy to find other than the dealer of course. Anyone use this machine and have mulching blades for it? Thanks for your help!
