I've had a x570 for about 7 months now, and bought it with the mulch kit installed. From day one its had this terrible vibration rattle. I locked down everything I could. Greased everything.. (,no luck) it didnt do this on the dealers lot (pre mulch kit) .. so off comes the jd mulch blades and on go the original standard blades. Ahhhh.. no more vibration / rattle. Took the mulch blades, hung them on a nail. And they all lean a little to the left. So. I will attempt to re- balance .. but if I fail at this... what would you reccomend for the x570 with the mulch kit ? Gator G6 ? That is what I have been seeing in old posts.. but is that still the consensus now ?
