I bought my disk at the ASC store in Petersburg, Virginia. I went on their web site and they will sell them and ship them ground. $43 plus tax plus whatever it cost to ship it to AZ, cant imagine its too much, depends on how much of a hurry you're in. I also noticed there are no ASC "Agri Supply Centers" in AZ but there are a number of other farm suppliers and ag stores there, I don't know if there are any disc blade distributors but I'd give it a shot.
I guess a discada is something like a bowl shape with three or for legs welded on it?
never been a horse that couldn't be rode, never been a man that couldn't be throw'd.
