Re: How much is it worth? It\'s getting sold!
Assuming it fits enough models to create demand, ebay might be a good way to go. What you get for it won't compare to the price of one new! I have seen quite a few 60" decks for the BX series go for 900-1000. I don't remember the condition they were in. It's doubtful you will get 1/2 what it costs new.
If you are in need of RFM or other implement, you might check with your Kubota dealer to see about a trade-in. He won't give you more than you could ebay it for, but it would be much easier to make it all happen - rather time consuming to arrange for shipping a mowing deck and who knows the cost to ship that adds to purchaser's price.
