Why won't my Toro Lawn Mower engine start?
- T
  Tyler PhillipsJul 31, 2025
  If your Toro Lawn Mower engine won't start, starts with difficulty, or stalls frequently, there are several potential causes. Start by ensuring the fuel tank isn't empty and fill it if necessary. Check that the choke is engaged. A dirty air cleaner can also be the culprit, so clean or replace it. Make sure the spark plug wire(s) is securely connected. Inspect the spark plug(s) for damage or incorrect gap and replace if needed. Also, ensure that the oil level in the crankcase is sufficient by adding oil if needed. Finally, check that the correct fuel is in the fuel tank; if not, drain and replace it.

Why does my Toro 74812 engine lose power?
- D
  Donna StoutAug 4, 2025
  If your Toro Lawn Mower engine loses power, there are several things to check. First, reduce the ground speed if the engine load is excessive. Clean the air cleaner element if it's dirty. Add oil to the crankcase if the oil level is low. Remove any obstructions from the cooling fins and air passages under the engine blower housing. Replace the spark plug(s) if they are pitted, fouled, or have an incorrect gap. Open the vent in the fuel cap if it is closed. Replace the fuel filter if it's dirty. If there is incorrect fuel in the fuel tank, drain the tank and replace the fuel with the proper type.

Why don't the blades rotate on my Toro Lawn Mower?
- R
  Rebecca MedinaAug 8, 2025
  If your Toro Lawn Mower blades do not rotate, the drive belt may be worn, loose, or broken and needs replacing. Alternatively, the drive belt may have come off the pulley; if so, reinstall the drive belt and check the adjusting shafts and belt guides for the correct position. Also, the mower belt may be worn, loose, or broken, requiring a new mower belt.

How to fix uneven cutting height on my Toro 74812 Lawn Mower?
- D
  Debra Torres DDSAug 12, 2025
  If your Toro Lawn Mower provides an uneven cutting height or poor quality of cut, start by sharpening the blade(s). If a cutting blade(s) is/are bent, install a new cutting blade(s). If a blade is loose, tighten the blade mounting bolt and inspect the blade spring disk washers for damage. Level the mower from side-to-side and front-to-rear. Adjust the anti-scalp wheel height if it is not set correctly. Clean the underside of the mower if it is dirty. Adjust the tire pressure if it is incorrect.

  Christine RoweAug 17, 2025
  If the engine of your Toro Lawn Mower overheats, it might be due to several reasons. First, the engine load could be excessive, so try reducing the ground speed. Second, check if the oil level in the crankcase is low and add oil if needed. Also, inspect the cooling fins and air passages under the engine blower housing for any obstructions and remove them. Finally, the air cleaner might be dirty, so clean or replace the air cleaner element.

What to do if the starter does not crank on my Toro 74812 Lawn Mower?

  Lisa RamirezAug 21, 2025
  If the starter on your Toro Lawn Mower isn't cranking, check a few things. Make sure the blade control switch is disengaged. Ensure the motion control levers are in the park position. Confirm you are seated on the seat. If these aren't the issue, check the battery charge and charge it if necessary. Inspect electrical connections for corrosion or looseness, and ensure they're making good contact. Finally, check the fuse and replace it if blown.

Why is there abnormal vibration in my Toro Lawn Mower?
- G
  gjonesAug 26, 2025
  If you notice abnormal vibration in your Toro Lawn Mower, start by tightening the engine mounting bolts. Then, tighten the engine pulley, idler pulley, or blade pulley if any of them are loose. If the cutting blade(s) is/are bent or unbalanced, install a new cutting blade(s). Also, tighten the blade mounting bolt and inspect the blade spring disk washers for damage if a blade is loose.
