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, blown PTO fuse, or blades slowing down after the mower heats up.

What should I check before installing a new PTO clutch?

Inspect the PTO switch, wiring connector, battery voltage, deck belt, idler pulleys, blade spindles, anti-rotation pin or bracket, and crankshaft condition. A damaged anti-rotation setup, weak electrical supply, seized idler, or dragging spindle can damage a new clutch.
