Might be another PTO switch... Some scags eat PTO switches , If it is , check wiring for melted connectors or loose connections., The safety system uses the PTO switch .

To bypass the safeties (TEMPORARILY) Disconnect the white wire that goes to the engine, at the pigtail on the engine, The engine will take about 3 sec to shut off with this wire disconnected.
