The Spec sheet in the owner's manual says 200 lb. I've installed/removed and toted it around a few times, and it feels more like 500 lb. /forums/images/graemlins/grin.gif
Being a geek, I actually weighed my X 595 when I had it. I did so with and without the mower deck, which was a 62C. Mine weighed 230 pounds more with the mower and with the chute and suspending hardware. Hopefully this is somewhat helpful.
