I have been looking for a parts Manuel so that one I have a list of parts an two so I can find the parts to replace what I need. I know that the patient was sold to John deere but when I call them to get the parts they tell me I need to have the parts numbers so that they can match them but my atv still runs an drives I just don't want to have to tear it down an have it be down till I get the parts. Can anybody help
