    What to do if Toro Lawn Mower starter does not crank?
    • A
      Alan WalshSep 18, 2025
      If the starter on your Toro Lawn Mower isn't cranking, there are a few things you can check. First, make sure the blade-control switch is disengaged. Ensure the motion-control levers are in the PARK position. If the battery is dead, charge it. Check the electrical connections for any corrosion or looseness and ensure they have good contact. Also, inspect the fuse and replace it if it's blown. For issues like a damaged relay or switch, it's recommended to contact an Authorized Service Dealer.

    Why is my Toro 74388 cutting height uneven?
    • J
      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?
    • A
      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.
