How to fix a Toro 74389 engine that loses power?
- M
  Michelle ReynoldsSep 5, 2025
  If your Toro Lawn Mower engine is losing power, consider these potential causes. The engine load might be too high, so reduce your ground speed. A dirty air cleaner can also cause power loss, so clean it. Check the oil level in the crankcase and add oil if necessary. Also, remove any obstructions from the cooling fins and air passages under the engine blower housing. Finally, inspect the spark plug(s) and replace if pitted, fouled, or incorrectly gapped.

How to adjust a Toro 74389 Lawn Mower for an even cut?

  Jeffrey MyersSep 5, 2025
  If your Toro Lawn Mower is leaving an uneven cut, several issues could be the cause. Start by sharpening the blade(s). If a cutting blade(s) is/are bent, replace it. Make sure the mower is level from side-to-side and front-to-rear. If equipped, check the anti-scalp roller setting and adjust the anti-scalp wheel height. Clean the underside of the mower deck. Finally, ensure the tire pressure is correct.

What to do if Toro 74389 Lawn Mower blades won't spin?

  Jared FreemanSep 6, 2025
  If the blades on your Toro Lawn Mower aren't rotating, it could be due to a worn, loose, or broken drive belt. Install a new drive belt. Also, check if the drive belt is off of the pulley, and if so, install the drive belt and check the adjusting shafts and belt guides for the correct position. Finally, check if the mower belt is worn, loose, or broken and install a new mower belt.

Why does my Toro 74389 engine lose power?

  Dylan DunlapSep 7, 2025
  If your Toro Lawn Mower engine is losing power, consider these potential causes: The engine load might be too high, so reduce the ground speed. A dirty air cleaner can restrict airflow, so clean the air-cleaner element. Check the oil level in the crankcase and add oil if necessary. Clear any obstructions from the cooling fins and air passages under the engine blower housing. Replace the spark plug(s) if it is pitted, fouled, or the gap is incorrect. If there is incorrect fuel in the fuel tank, drain the tank and replace the fuel with the proper type. For issues like a blocked fuel-tank vent, dirt, water, or stale fuel in the fuel system, it's best to contact an Authorized Service Dealer. Also, if there is dirt in the fuel filter, replace the fuel filter.
