Why won't my Toro 74433 Lawn Mower engine start?
- C
  Colleen SharpAug 22, 2025
  Your Toro Lawn Mower might not start due to several reasons. The fuel tank could be empty, so fill it up. The fuel valve may be turned off, so open it. The choke might not be on, so move the choke lever to the On position. The air filter could be dirty, so clean or replace it. A spark plug wire could be loose, so install it correctly. The spark plug itself might be bad, so replace it with a new, correctly gapped one. There might be dirt in the fuel filter, so replace the filter. Also, the fuel could be stale or the wrong type, or the oil level may be low, so address those issues accordingly.

  If your Toro Riding mower engine won't start, starts hard, or fails to keep running, several factors could be at play. First, ensure the fuel tank isn't empty and the fuel valve is open. Check that the choke is on and the air cleaner isn't dirty; clean or replace the air cleaner element if needed. Make sure the spark plug wire(s) is securely connected and the spark plug(s) isn't damaged—replace if necessary, ensuring correct gapping. Also, verify that the fuel filter isn't clogged with dirt. If the oil level in the crankcase is low, add oil. If the fuel system contains dirt, water, or stale fuel or the fuel tank has incorrect fuel, it's best to contact an Authorized Service Dealer.

Why does my Toro 74433 Lawn Mower engine lose power?
- B
  Beth Harris MDAug 27, 2025
  Your Toro Lawn Mower engine might be losing power for a few reasons. The engine load could be too high, so try reducing your ground speed. A dirty air cleaner can also cause this, so clean it. Check the oil level and add oil if it's low. Make sure the cooling fins and air passages are free from obstructions. Inspect the spark plug and replace if needed. Ensure the vent in the fuel cap is open. Finally, the fuel filter may be dirty, so replace it, or the fuel itself may be old or incorrect, so replace it with the proper type.

  If your Toro Lawn Mower is leaving an uneven cut, the blade(s) might not be sharp, so sharpen them. A cutting blade could be bent, so replace it. Ensure the mower is level from side to side and front to rear. Check that the anti-scalp wheel is set correctly and the underside of the mower is clean. Also, verify that the tire pressure is correct.

Why don't the blades rotate on my Toro 74433 Lawn Mower?
- J
  Jeffrey AndersonAug 31, 2025
  If the blades on your Toro Lawn Mower aren't rotating, it could be because the drive belt is 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 could also be worn, loose, or broken, so replace it with a new one. Finally, the collection bag might not be properly installed, so check the bag and make sure it is seated flush with machine frame and presence switch is engaged.
