Yea every thing is breaking down on me. Go to turn on blades and only the switch moves nothing else. Is there a systamatic way of trouble shooting this problem. Its a 48 inch hydro scag ,electric clutch.Where does it get power to energize the clutch, from the engine , its a pull start.How do I tell if its a mechanical failure or eletrical malfunction.The only thing I know about cluthes is that when they spin fast ,cetrifical force expands the springs to grab and drive the whatever it is you want to drive,or set in motion. Please help the OLDDDD TROUBLE MAKER ! thank you for your help.
