So with 9.4 hours now on our month old X500 (I know I know, why does it ONLY have 9.4 hours on it, hey... it cut my mowing time by MORE than half from my old tractor). Anyway, JD dealer came out to do the break in service a couple days ago, now I'm noticing a strange banging sound coming from I think near the engine. It's hard to describe, almost sounds like, well when you hit the side of a hollow upside-down 5 gal bucket or something, lol. It isn't continuous, just makes this noise every so often. I don't know if I'm just worrying to much like usual or if it's something I should be closely monitoring.
