Why won't my Toro 74797 Lawn Mower start?
- B
  Brandon FriedmanAug 12, 2025
  If your Toro Lawn Mower engine won't start, starts hard, or fails to keep running, several issues could be the cause. Ensure the fuel tank is full. If the choke is not on, move the choke lever to the 'On' position. A dirty air cleaner can also cause this issue, so clean or replace it. Check that the spark plug wire(s) is securely connected to the spark plug. Replace any spark plugs that are pitted, fouled, or have an incorrect gap with new, correctly gapped ones. Also, if the oil level in the crankcase is low, add oil.

Why is the cutting height on my Toro 74797 Lawn Mower uneven?
- J
  James RiveraAug 16, 2025
  If the cutting height on your Toro Lawn Mower is uneven, consider these possible causes: dull blades (sharpen them), bent cutting blades (install new ones), or an unlevel mower (level it from side-to-side and front-to-rear). Check if an anti-scalp wheel is not set correctly and adjust its height. Clean the underside of the mower if it's dirty and adjust the tire pressure if it's incorrect.

Why is my Toro 74797 Lawn Mower losing power?
- D
  Dr. Jordan LynnAug 20, 2025
  If your Toro Lawn Mower engine loses power, several factors could be responsible. An excessive engine load might be the cause, so reduce your ground speed. A dirty air cleaner can also lead to power loss, so clean it. Additionally, check the oil level in the crankcase and add oil if it's low. Make sure that the cooling fins and air passages under the engine blower housing are free of obstructions. Replace any spark plugs that are pitted, fouled, or have an incorrect gap with new, correctly gapped ones. Finally, if there is dirt in the fuel filter, replace the fuel filter.

What to do if the blades do not rotate on my Toro 74797 Lawn Mower?

  Anita LesterAug 25, 2025
  If the blades on your Toro Lawn Mower aren't rotating, the drive belt might be worn, loose, or broken, so install a new one. Also, the drive belt could be off the pulley, so install the drive belt and check the adjusting shafts and belt guides for the correct position. The mower belt may also be worn, loose, or broken, so install a new mower belt.

  If your Toro Lawn Mower engine overheats, several factors could be the cause. First, the engine load might be excessive, so try reducing your ground speed. Another cause could be low oil level in the crankcase, so add oil. Also, check if the cooling fins and air passages under the engine blower housing are plugged and remove any obstructions. Finally, a dirty air cleaner can cause overheating, so clean or replace the air cleaner element.

Why is my Toro 74797 Lawn Mower vibrating abnormally?
- D
  Diane GraySep 4, 2025
  If you're experiencing abnormal vibration with your Toro Lawn Mower, start by checking if the engine mounting bolts are loose and tighten them if necessary. Then, inspect the engine pulley, idler pulley, or blade pulley for looseness and tighten the appropriate pulley. If the cutting blades are bent or unbalanced, install new ones. Lastly, make sure the blade mounting bolt is tightened.
