Never thought about the yard playground equipment replaced, because before we moved here to the playground equipment has been, possibly is the former owner to stay, but probably because it is more long, is some old, but my son is particularly fond of, then come back and check one of my friends say the playground equipment in some of the old, there may be a hidden danger, should get a new one, I think is really should consider this problem, my son almost every day to play, if really happen problem, it is late.
