hey bought a JD165 hydro last year been fixing it up with my little boy when we have time. it has a 38in deck. I acquired a power flow bagger unit and modified it to fit the deck since one was not made for this model. my issue is the double stack pully I need for the deck. I do not believe that one was made for this model either but need something that would work for this deck. I asked JD dealer they could not help. does anyone know where I can find the part I need or if I have to make one myself?
