Walk Behind Lawn Mowers

Day before yesterday while mowing my mower started to smoke under the hood and in just a few seconds was in flames. I was far enough from the house that water was not immediately available so by the time a got back to put out the fire the entire mover was engulfed. It completely burnt to the ground. It was a 48" riding mower with only 212 hours on it. I was wondering if this had occurred with other mowers or maybe there was a recall for something that I missed. I am looking for answers. Thanks
