I haven't heard of the four disk plate problem but have come across mowers with snapped cranks with the single blade type cutter bar. One was a brand new mower that hit a small garden stake on its very first outing. Of course there is no warranty cover but it is terrible design that they don't at least have some sort of friction washer that will take most of the impact.
