  If the Toro Lawn Mower engine overheats, several factors could be responsible. The engine load might be excessive, so reduce the ground speed. Check the oil level in the crankcase and add oil if it's low. Inspect the cooling fins and air passages under the engine blower housing for obstructions and remove them. Also, the air cleaner might be dirty, so clean or replace the air-cleaner element. If you suspect dirt, water, or stale fuel in the fuel system, contact an Authorized Service Dealer.

  If your Toro Lawn Mower engine loses power, consider these possible causes. Start by reducing the ground speed, as the engine load may be excessive. Check and clean the air-cleaner element if it's dirty. Ensure the oil level in the crankcase is sufficient by adding oil if needed. Clear any obstructions from the cooling fins and air passages under the engine blower housing. Replace the spark plug(s) if it's pitted, fouled, or has an incorrect gap. For fuel-related issues like a blocked fuel-tank vent, dirt in the fuel filter, or incorrect/stale fuel, it's best to contact an Authorized Service Dealer.

  If the blades on your Toro Lawn Mower do not rotate, the drive belt may be worn, loose, or broken, requiring replacement. Alternatively, the drive belt might be off the pulley; reinstall it, ensuring correct positioning of the adjusting shafts and belt guides. In case of a faulty power-takeoff (PTO) switch or PTO clutch, or if the mower belt is worn, loose, or broken, it is best to contact an Authorized Service Dealer.
