What are common signs of a failing PTO clutch?

Common symptoms include mower blades not engaging, the PTO clutch clicking but the blades not spinning, slipping under load, intermittent blade engagement, a burning smell, or blades slowing down after the mower heats up. A worn coil can work cold, then weaken after 10 to 30 minutes of mowing.
