Gentlemen: Thank you all for responding. I have always been able to get good answers here. The pic. was great. After I got your responses I went to Home Depot where I could look at a new "clean" machine! Came home, removed the battery for better access. Unfortunately the switch was in place and the activation paddle was depressing the switch button all the way. So, since I have a 145 for backup I'll order a switch online as I have found that parts at our local John Deere dealer to be on the high side. Again thanks so much for getting me on the right track. I'll let you know the end results.
