Thanks for your response. It is 42 inch deck. Not sure exactly which one. The first photo shows two broken belts, pretty clean rip. The second and third photo are under deck, cutting blade removed where I see friction showing where the blade meets the pulley rod. Do you think this could cause it? There is a little cup that comes off the rod, do I just replace that? 4th photo cup in my hand. Or am I totally off with this idea?
