Today my helper and i were mulching leaves. I was in the backyard and he in the front, out of the corner of my eye i see him sprinting for the truck so i ran to see what was up. MOWER ON FIRE- MOWER ON FIRE!!! Well thank god we put it out ,with a hat and water from the cooler(his hat) his hat was a total loss and the mower needs and air cleaner assembly. Please be carefull and keep all leaves off the exhaust. The thought of that yard and or the the neighborhood going up in smoke scared the bajeebas out of me. Monday i will have a fire extinguiser for all mowers. Be safe and mulch on.
