I have a 52" xonei, badest mower. No issues at all accept in the beginning. It would Bog after around 30 minutes run time. Several times to the shop, they said, oh you probably have dirt in the fuel. I thought, no way, its brand new and the mower is kept clean. Turns out, it needed a bigger fuel filter. Hustler said that the one on it was restricting fuel flow. Im around 750 hours and need to change hydro fuel and filter. Anyone ever do that? thanks
