I have the problem with my new z550. It was working find and then it would not go forward or reverse. When you lift the seat you can see a spring about a foot long hanging down from a pulley but I cant tell where it goes
tglundy1958 could possibly lead to a safety switch or an idler pulley for the drive belt etc. Post some good pictures of what you are looking at with your question. That way we can see what you see. Adding images to an existing question
