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.

  John BoydAug 25, 2025
  Uneven cutting height with your Toro Lawn Mower can occur for several reasons. Start by sharpening the blade(s) or replacing them if bent. Ensure the mower is level from side to side and front to rear. Check and adjust the anti-scalp wheel height if it's not set correctly. Clean the underside of the mower if it's dirty. Adjust the tire pressure if it's incorrect. If a blade spindle is bent, contact an Authorized Service Dealer.

  If the blades on your Toro Lawn Mower do not rotate, first check the drive belt. If it is worn, loose, or broken, install a new one. If the drive belt is off of the pulley, install it and check the adjusting shafts and belt guides for the correct position. If the Power Take-Off (PTO) switch or PTO clutch is faulty, contact an Authorized Service Dealer. Finally, if the mower belt is worn, loose, or broken, install a new mower belt.

Why Toro 74388 engine does not start?

  Audrey SteinAug 27, 2025
  Several factors can prevent your Toro Lawn Mower's engine from starting. It could be as simple as an empty fuel tank; in this case, fill the fuel tank. Other potential causes include a missing choke (move the choke lever to On), a dirty air filter (clean or replace it), a loose or disconnected spark-plug wire (secure the wire to the spark plug), a faulty spark plug (replace with a new, correctly gapped one), a dirty fuel filter (replace it), incorrect fuel type (drain and replace with the proper type), or low oil level (add oil to the crankcase). If the problem persists, there might be dirt, water, or stale fuel in the fuel system, and you should contact an Authorized Service Dealer.

How to fix a Toro 74388 Lawn Mower when the starter does not crank?

  Kristen SmithAug 27, 2025
  If the starter on your Toro Lawn Mower isn't cranking, start by ensuring the blade-control switch is disengaged. Also, make sure the motion-control levers are in the PARK position. Check the battery and charge it if it's dead. Inspect the electrical connections for corrosion or looseness, ensuring they have good contact. Replace the fuse if it's blown. If these steps don't solve the problem, a relay or switch may be damaged, requiring you to contact an Authorized Service Dealer.
