Thanks mechanic mark.... Turned out to be just the driver belt somehow slipped off the front drive pulley..... Was an easy fix. Removed the brace plate and then it was fairly easy to slide the belt back on the pulley.... Not sure how this happened but maybe a small tree branch worked it's way between the belt and pulley..... I have a lot of little branches... The black smoke was from the belt. Thanks again... This is a great forum.....
