This is a replacement deck for a used mower I bought. The old deck was rusted through, spindles worn and a few other problems, by the time I figured what it was going to cost me to repair the old deck it was cheaper to buy a new one. The mower had 264 hours on it when I changed the deck hopefully this one will last a lot longer. It was easy to replace, used it once before winter set in and is great so far.
