Hello Rick,
Not sure how pricing varies from State to State or even Country to Country. I can tell you that the JD dealer I deal with offered me $15,000 ( CDN ) for my 2004 4010 with 250 hrs.(trade in) including 410 fel, 54" deck, ballast box. Privately I have listed it for $17,500 (CDN). I have had a lot of serious buyers.( to my surprise) 2 coming Saturday to take a look. I thought that was high but when you look in my area there is nothing available used in good condition. Just remember you can always come down in price . Seems to me like a really good deal especially with all the attachments! Good luck.
Also check into trading it in. Dealer may give you a ball park figure were to start.
Happy tractoring!
