Why won't my Toro 74642 Lawn Mower engine start?
- M
  Melissa RiveraAug 18, 2025
  If your Toro Lawn Mower engine is not starting, starts with difficulty, or stops running, several factors could be at play. First, ensure that the fuel tank isn't empty by filling it. If that's not the issue, check if the choke is properly engaged by moving the choke lever to the 'On' position. A dirty air cleaner can also cause problems, so clean or replace it. Inspect the spark plug wire(s) to ensure they are securely connected to the spark plug. If the spark plug(s) is damaged, replace it with a new, correctly gapped one. Also, 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. Finally, make sure that the oil level in the crankcase isn't low by adding oil to the crankcase.

  Katelyn BlackAug 26, 2025
  If the cutting height on your Toro Lawn Mower is uneven, several factors could be the cause. Start by sharpening the blade(s). If that doesn't resolve the issue, the cutting blade(s) might be bent, in which case you should install a new cutting blade(s). Ensure that the mower is level from side to side and front to rear. Check that the anti-scalp wheel is set correctly and adjust its height if necessary. Clean the underside of the mower, as a dirty underside can affect cutting height. Finally, ensure the tire pressure is correct and adjust if needed.

  If the starter on your Toro Lawn Mower isn't cranking, make sure the blade-control switch is disengaged. Also, ensure the motion-control levers are in the park position.

  If you're experiencing an abnormal vibration with your Toro Lawn Mower, begin by checking if the engine-mounting bolts are loose and tighten them if necessary. Inspect the engine pulley, idler pulley, or blade pulley for looseness and tighten the appropriate pulley. If the cutting blade(s) is/are bent or unbalanced, install a new cutting blade(s). Check if a blade mounting bolt is loose and tighten it.

  If the blades on your Toro Lawn Mower aren't rotating, the drive belt might be worn, loose, or broken, so install a new drive belt. Another possibility is that the drive belt is off of the pulley, so install the drive belt and check the adjusting shafts and belt guides for the correct position. The mower belt could also be worn, loose, or broken, so install a new mower belt.
