The belt came off my JD Z425 54" mower deck. My husband says one of the pulleys wobbles around so much that it caused the belt to come off. How do you replace the pulley? (Manual doesn't go into anything beyond removing & installing the mower deck.) How can we tell if anything else needs replacement (bearing or spindle, etc.) Is there a website with parts replacement diagrams? Anybody have experience with this?
