Sure- start by looking on Tractorhouse.com, then figure out what you paid for it, deduct how much value you got out of using it, add or subtract according to how perfectly clean and nice, or dinged and dirty it is, and multiply by how badly you want to sell it.
In reality, assuming its in good shape, maybe you paid $19000 for it in 2005, maybe ask $15000? Just guessing. That's low hours, inside storage means it probably looks, and operates, good, and is still a fully functional machine that's almost new- so it should be well worth something not too much less than you paid.
