Hey guys, I'm looking at getting a used FH500V from a Deere rider to transplant on my zero turn. It'll require a muffler, so I'm on the hunt.. I found a KA-Muffler 43 that is listed to fit FR481V, FR541V, FR600V, FS481V, FS541V, FS600V, FX481V, FX541V, FX600V Series engines, but it (obviously) skips the FH500V. So what if anything is different about it?
