thanks maverick,deereguy you might check with JD on the part for your 485 not sure it is the same one andyb gave you for your tractor. In the instructions it mentioned if you were installing on anything other than a X700 which means the X485,X585, etc then there was a PTO module to be installed. It is some sort of electronic box that goes in under the dash. The instructions must be generic for multiple kits as it gave steps on how to install it and it looked to be simple plug and play setup but for the X700 its says to skip this section of the instructions as it is not needed for X700 machines and there was no PTO module packaged in my kit.
i will do that when i get ready to get one.
