    Why does my Toro 74388 Lawn Mower engine overheat?
    • J
      Justin Morris DVMSep 12, 2025
      Your Toro Lawn Mower engine may overheat for several reasons. It could be due to an excessive engine load, in which case you should reduce the ground speed. Another cause might be a low oil level in the crankcase, so add oil. Also, check for obstructions in the cooling fins and air passages under the engine-blower housing and remove them. A dirty air cleaner can also cause overheating, so clean or replace the air-cleaner element. If dirt, water, or stale fuel is in the fuel system, contact an Authorized Service Dealer.

      If the starter on your Toro Lawn Mower doesn't crank, first ensure the blade-control switch is disengaged. Next, check that the motion-control levers are in the park position. If these are correct, the battery may be dead, so charge it. Also, examine the electrical connections for corrosion or looseness and ensure they have good contact. Finally, check the fuse and replace it if it's blown. If a relay or switch is damaged, contact an Authorized Service Dealer.

    What to do if my Toro 74388 Lawn Mower engine does not start?
    • M
      Michelle PotterAug 23, 2025
      If your Toro Lawn Mower engine doesn't start, starts hard, or fails to keep running, begin by checking if the fuel tank is empty and fill it if needed. Ensure the choke is on. Inspect the air cleaner and clean or replace it if it's dirty. Make sure the spark plug wire(s) is securely connected. If the spark plug(s) is damaged, replace it with a new, correctly gapped one. Also, check the fuel filter for dirt and replace if necessary. If there is dirt, water, or stale fuel in the fuel system, or incorrect fuel in the fuel tank, contact an Authorized Service Dealer. Finally, ensure that the oil level in the crankcase is adequate and add oil if low.

      If the engine in your Toro Lawn Mower loses power, the possible causes are: excessive engine load (reduce ground speed), a dirty air cleaner (clean it), low oil level in the crankcase (add oil), blocked cooling fins and air passages (clear the obstructions), or a faulty spark plug (install a new, correctly gapped one).
