Bought a used 60" power flow for my 455 60" mower deck ... thought i had everything figured out and all the parts ordered until Green Tractor parts just told me that the pulley that bolts ontop of the existing pulley on the mower deck which is supposed to power the Power Flow is not made by Deere anymore. Part number : AM117590. Ebay has nothing, craigslist nada, and im getting nervous that im not going to be able to get this thing working. Anyone have an old 60" deck with the pulley attached? Or have a space one?
