I am having trouble with the electric clutch that engages the blades on my riding lawnmower. Sometimes, when I disengage the blades, the clutch spins completely around and rips out the wires to the clutch. Sometimes it even breaks the wires and it is happening more often now. Other than that, the clutch works fine. What is the problem and how can I fix it?

The clutch housing is either worn, or the pin that goes in the hole that holds the clutch in place is broken, worn, or missing.
