Why does my Toro TimeCutter 75742 engine not start, start hard, or fail to keep running?
- K
  Kenneth HeathAug 3, 2025
  Several factors can cause this issue. First, ensure the fuel tank isn't empty; if it is, fill it. If your model has a choke, make sure it's on. Check the air cleaner and replace or clean it if it's dirty. Ensure the spark plug wire(s) are securely connected to the spark plug. Inspect the spark plug(s) for pitting, fouling, or incorrect gap, and replace if necessary. Check the fuel filter for dirt and replace it if needed. Also, ensure that you have the correct fuel type in the fuel tank. Finally, verify that the oil level in the crankcase is sufficient and add oil if it's low.

  Kristen BushAug 7, 2025
  A loss of power in your Toro Lawn Mower engine can stem from several causes. Check if the engine load is excessive and reduce the ground speed if needed. Ensure the air cleaner is clean; if it's dirty, clean it. Verify the oil level in the crankcase and add oil if it's low. Clear any obstructions from the cooling fins and air passages under the engine blower housing. Inspect the spark plug(s) for pitting, fouling, or an incorrect gap, and replace it if necessary. Check the fuel filter for dirt and replace it if needed.

How to fix uneven cutting height on my Toro Lawn Mower?
- S
  Sally HawkinsAug 11, 2025
  Uneven cutting height on your Toro Lawn Mower can be caused by several factors. Start by sharpening the blade(s). If a cutting blade(s) is/are bent, install a new cutting blade(s). Ensure the mower is level from side-to-side and front-to-rear. If applicable, check that the anti-scalp roller is set correctly and adjust the anti-scalp wheel height. Clean the underside of the mower deck. Adjust the tire pressure.

  Michael RamosAug 15, 2025
  If your Toro Lawn Mower engine is overheating, there could be several reasons. First, the engine load might be excessive, so try reducing the ground speed. Check the oil level in the crankcase and add oil if it's low. Make sure the cooling fins and air passages under the engine-blower housing are free from obstructions. Also, ensure the air cleaner is clean; if it's dirty, clean or replace the air-cleaner element.

  Austin SilvaAug 20, 2025
  If the starter on your Toro Lawn Mower isn't cranking, first ensure that the blade-control switch is disengaged. Next, confirm that the motion-control levers are in the PARK position. Check the battery and charge it if it's dead. Inspect the electrical connections for corrosion or looseness and ensure they have good contact. Finally, check the fuse and replace it if it's blown.

Why does my Toro TimeCutter 75742 Lawn Mower vibrate abnormally?
- K
  Kathy VazquezAug 25, 2025
  Abnormal vibration in your Toro Lawn Mower can arise from several sources. Check the cutting blade(s) for bending or imbalance, and install new ones if necessary. Ensure the blade mounting bolt is tightened securely. Verify that the engine mounting bolts are also tight. Additionally, inspect the engine pulley, idler pulley, or blade pulley for looseness and tighten the appropriate pulley.

What to do if the blades do not rotate on my Toro Lawn Mower?
- R
  Rose KnoxAug 29, 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, checking the adjusting shafts and belt guides for the correct position. Another possible cause is a worn, loose, or broken mower belt, in which case you should install a new mower belt.
