Where is this switch? How do I find and replace it? If this switch is "dead or cooked" how can my PTO still work? You see, while the engine is running, I pull the PTO switch, the PTO engages and begins to spin. At the same time I pull the switch, the engine quits. If I quickly release the PTO switch, the engine will catch and continue running. Even with the engine OFF but with the key in the ON position, when I pull the PTO switch I can hear the PTO engage or disengage. What shall I check next?
