    Why won't my Toro GrandStand 74589 Lawn Mower engine start?
    • S
      steven26Aug 20, 2025
      Your Toro Lawn Mower engine might not start due to several reasons: the fuel tank could be empty or the shut-off valve closed (fill the tank and open the valve); the spark plug wire might be loose (install the wire); the spark plug could be faulty (replace it with a new, correctly gapped one); or the air cleaner might be dirty (service the air cleaner element). Also, there may be dirt in the fuel filter, which requires replacing it.

    How to fix Toro Lawn Mower that will not start?

      If your Toro Lawn Mower engine won't start, starts hard, or fails to keep running, several factors could be at play. First, ensure the fuel tank isn't empty and the shut-off valve is open; if not, replenish the fuel and open the valve. Next, check the spark plug wire to confirm it's securely connected. A faulty spark plug could also be the culprit, so inspect it for pitting or fouling and replace if necessary with a correctly gapped one. Also, a dirty air cleaner can cause this issue, so service the air cleaner element. Finally, check the fuel filter for any dirt and replace it if needed.

    What to do if the cutting blades do not rotate on my Toro Lawn Mower?
    • M
      mloweryAug 25, 2025
      If the cutting blades on your Toro Lawn Mower do not rotate, there are several potential causes. First, check the drive belt for wear, looseness, or breakage and check the belt tension. If the drive belt is off the pulley, install the drive belt and check the adjusting shafts and belt guides for correct position. If the mower deck belt is worn, loose, or broken, install a new mower deck belt. If the mower deck belt came off a pulley, install the mower deck belt and check the idler pulley, idler arm, and spring for the correct position and function. A broken or missing idler spring can also prevent blade rotation, so replace the spring.

    Why does my Toro GrandStand 74589 Lawn Mower engine lose power?
    • N
      Natalie MunozAug 27, 2025
      Your Toro Lawn Mower engine might be losing power because the engine load is excessive, so reduce the ground speed. The air cleaner may be dirty, so clean it. Check the oil level in the crankcase and add oil if needed. Make sure that the cooling fins and air passages above the engine are not plugged and remove any obstructions. The vent hole in the fuel cap might be plugged, so clean or replace the fuel cap. Finally, the fuel filter may be dirty, so replace it.

      If your Toro Lawn Mower engine is losing power, there are several potential causes. Make sure that the engine load isn't excessive by reducing your ground speed.

Ensure that the cooling fins and air passages above the engine are free from obstructions. The vent hole in the fuel cap may be plugged, so clean or replace the fuel cap. Finally, a dirty fuel filter can cause power loss, so replace the fuel filter.

    What to do if the Malfunction Indicator Light (MIL) comes on in my Toro Lawn Mower?
    • V
      Vincent PonceSep 3, 2025
      If the Malfunction Indicator Light (MIL) illuminates on your Toro Lawn Mower, it could be due to several reasons. The engine might be too hot, so turn it off and let it cool. Old gas in the tank can also trigger it, so use new gas. Ensure the fuel shut-off valve is fully open. Check the air cleaner and precleaner, clean them, or replace if necessary. Also, verify the battery is charged, and check/replace any blown fuses. Make sure a good 12 volt battery is being used and is fully charged.
