Why won't my Toro Lawn Mower engine start?
- T
  thomasmichaelAug 13, 2025
  Your Toro Lawn Mower engine might not start due to several reasons. First, ensure the fuel tank isn't empty by filling it. If it has fuel, check if the choke is properly engaged. A dirty air cleaner can also prevent starting, so clean or replace it. Make sure the spark plug wire is securely connected. The spark plug itself might be faulty, so consider replacing it with a new, correctly gapped one. Also, inspect the fuel filter for dirt and replace if necessary. Low oil level can also be the culprit, so add oil to the crankcase.

Why is my Toro 75747 Lawn Mower engine losing power?
- J
  James SummersAug 17, 2025
  Your Toro Lawn Mower engine may be losing power for a few reasons. An excessive engine load could be the cause, so reduce the ground speed. A dirty air cleaner can restrict airflow, so clean it. Low oil level in the crankcase can also lead to power loss, so add oil. Check the cooling fins and air passages under the engine blower housing for any obstructions and remove them. A faulty spark plug(s) can also cause power loss, so install a new, correctly gapped spark plug(s). Replace the fuel filter if it's dirty.

  Steven RobinsonAug 20, 2025
  Abnormal vibrations in your Toro Lawn Mower can stem from several sources. Start by checking the cutting blades for bending or imbalance; replace them if necessary. Ensure the blade mounting bolt is tightened securely. Next, verify that the engine mounting bolts are also tight. Additionally, check the engine pulley, idler pulley, or blade pulley for looseness and tighten the appropriate pulley.

Why is the cutting height uneven on my Toro 75747 Lawn Mower?
- C
  Caleb MendezAug 25, 2025
  Uneven cutting height on your Toro Lawn Mower can be caused by several factors. Start by sharpening the blades. Bent cutting blades can also cause this issue, so replace them if necessary. Ensure the mower is level from side-to-side and front-to-rear. Check the anti-scalp roller setting and adjust the anti-scalp wheel height. Clean the underside of the mower deck. Finally, verify and adjust the tire pressure.

  Beverly WilsonAug 31, 2025
  If your Toro Lawn Mower engine is overheating, there are several possible causes. First, the engine load may be excessive, so reduce the ground speed. Check the oil level in the crankcase and add oil if it is low. Also, inspect the cooling fins and air passages under the engine-blower housing for obstructions and remove them. A dirty air cleaner can also cause overheating, so clean or replace the air-cleaner element.

What to do if the starter on my Toro 75747 won't crank?
- T
  Tina GomezSep 5, 2025
  If the starter on your Toro Lawn Mower isn't cranking, several issues could be the cause. Ensure the blade-control switch is disengaged. Also, make sure the motion-control levers are in the PARK position. A dead battery can prevent cranking, so charge the battery. Check the electrical connections for corrosion or looseness, and ensure they have good contact. Lastly, inspect the fuse and replace it if blown.

What to do if the blades on my Toro 75747 do not rotate?
- M
  Mrs. Deanna Mercer DDSSep 8, 2025
  If the blades on your Toro Lawn Mower aren't rotating, it could be due to a worn, loose, or broken drive belt, so install a new drive belt. It's also possible that the drive belt has come off the pulley, so install the drive belt and check the adjusting shafts and belt guides for the correct position. Another possibility is a worn, loose, or broken mower belt, so install a new mower belt.
