The engine of your Toro Lawn Mower may overheat if: * The engine load is excessive; reduce the ground speed. * The oil level in the crankcase is low; add oil to the crankcase. * The cooling fins and the air passages above the engine are plugged; remove the obstruction from the cooling fins and the air passages.
