Lawn Mower Blade Won't Engage

On a Craftsman riding mower, the blades are engaged by a PTO (Power Take-Off) switch or lever that activates a clutch and belt system underneath the deck. When you engage the PTO and nothing happens, the problem is usually a broken or slipped belt, a faulty PTO switch, or a seized blade spindle.
