      Your Toro Lawn Mower engine may overheat due to a few reasons. One potential cause is excessive engine load, so reduce the ground speed. Also, check the oil level in the crankcase and add oil if it's low. Another common reason is blocked cooling fins and air passages under the engine blower housing; remove any obstructions.
