Why does my Toro TimeCutter 74774 Lawn Mower engine not start, start hard, or fail to keep running?
- A
  Andrew CollinsAug 5, 2025
  Several factors can cause this issue. The fuel tank might be empty, so refill it. The air cleaner could be dirty, requiring cleaning or replacement. Check if the spark plug wire(s) is loose or disconnected and install the wire(s) on the spark plug. A spark plug(s) may be pitted, fouled, or have an incorrect gap, so install a new, correctly gapped spark plug(s). The fuel filter may be dirty, so replace it. The oil level in the crankcase might be low, so add oil to the crankcase. Finally, ensure that you are using the correct fuel type; if not, drain the tank and replace the fuel with the proper type.

Why is my Toro Lawn Mower cutting height uneven?
- D
  David CooleyAug 9, 2025
  An uneven cutting height on your Toro Lawn Mower can be due to several reasons. The blade(s) may not be sharp, so sharpen the blade(s). A cutting blade(s) may be bent, so install a new cutting blade(s). The mower might not be level, so level the mower from side-to-side and front-to-rear. An anti-scalp wheel may not be set correctly, so adjust the anti-scalp wheel height. The underside of the mower could be dirty, so clean it. Finally, the tire pressure might be incorrect, so adjust the tire pressure.

What to do if the blades do not rotate on my Toro Lawn Mower?
- L
  Lori HuntAug 14, 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. Alternatively, the drive belt might be off the pulley, so install the drive belt and check the adjusting shafts and belt guides for the correct position. Also, the mower belt could be worn, loose, or broken, so install a new mower belt.

Why is my Toro Lawn Mower engine losing power?
- R
  Ryan KnightAug 18, 2025
  A loss of power in your Toro Lawn Mower engine can stem from several causes: excessive engine load, which can be resolved by reducing ground speed; a dirty air cleaner, which requires cleaning; or a low oil level in the crankcase, necessitating the addition of oil. Furthermore, check for obstructions in the cooling fins and air passages under the engine blower housing and remove them if present. Ensure the spark plug(s) is in good condition; if pitted, fouled, or incorrectly gapped, replace it. Check the fuel filter for dirt and replace if necessary. Finally, if you are using incorrect fuel, drain the tank and replace it with the proper type.

What to do if my Toro TimeCutter 74774 engine overheats?
- R
  Ryan GibbsAug 23, 2025
  If your Toro Lawn Mower engine is overheating, several factors could be the cause. First, the engine load might be excessive, so reduce the ground speed. Second, the oil level in the crankcase might be low, so add oil to the crankcase. Third, check the cooling fins and air passages under the engine blower housing for obstructions and remove them. Fourth, a dirty air cleaner can cause overheating, so clean or replace the air-cleaner element.

- C
  chansonAug 27, 2025
  If the starter on your Toro Lawn Mower isn't cranking, here are a few things to check: Ensure the blade-control switch is disengaged. Make sure the motion-control levers are in the PARK position. Verify the battery isn't dead by charging it. Inspect the electrical connections for corrosion or looseness, and ensure they have good contact. Check for a blown fuse and replace it if necessary.

- D

  If your Toro Lawn Mower is vibrating excessively, check the following: Tighten any loose engine-mounting bolts. Ensure the engine pulley, idler pulley, or blade pulley is tightened appropriately. If the cutting blade(s) is bent or unbalanced, install a new cutting blade(s). Also, tighten any loose blade-mounting bolts.
