While mowing, the blades stopped working. I disconnected the clutch power connector, tested, and get 12v with the mower on and switch pulled up. I also noted the belt on the clutch was falling off which led me to inspect the deck. There, I found the idler arm loose as the bolt that holds it to the deck had snapped. So what happened? I obviously have to replace that bolt but is the clutch gone? I do not see it move when I engage the switch but I feel like I hear a slight clunk (if that means anything). I´m no mechanic so any help is greatly appreciated. Thank you.
