Thanks for the tip. I did remove the safety switch and noticed 2 small factory notches in it through which I slid a narrow wire tie (1/8"). I then inserted the plug and brought the wire tire up around the plug and locked it. The mower started right up and the PTO engaged the blades so I think I'm good to go for now. I wonder if these notches were for a clip on the plug that has since disappeared. I will try to post a picture of how this looks in an effort to show others who have this problem happen how it can be fixed. First I want to make sure it stays put when I mow. I've got to roll my yard. It's crazy how bumpy it got over the winter.
