Why Toro 74704 engine will not start?
- C
  Chad SimsAug 18, 2025
  Your Toro Lawn Mower engine might not start due to several reasons. The fuel tank could be empty, so you should fill it. 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. Also, a dirty air cleaner can prevent starting, so clean or replace the air cleaner element. Ensure the spark plug wire(s) is properly connected to the spark plug. Install a new, correctly gapped spark plug(s) if the current one is pitted, fouled, or has an incorrect gap. 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, add oil to the crankcase if the oil level is low.

Why Toro 74704 Lawn Mower engine loses power?
- C
  Carolyn OlsonAug 23, 2025
  If your Toro Lawn Mower engine is losing power, consider these potential causes. The engine load may be too high, so reduce your ground speed. A dirty air cleaner can restrict airflow, so clean the air cleaner element. Low oil level in the crankcase can also cause power loss, so add oil to the crankcase. Check for obstructions in the cooling fins and air passages under the engine blower housing and remove them. Replace the spark plug(s) if it is pitted, fouled, or the gap is incorrect. Ensure the vent in the fuel cap is open. Replace the fuel filter if it is dirty. If there is incorrect fuel in the fuel tank, drain the tank and replace the fuel with the proper type.

Why is my Toro 74704 cutting height uneven?

  Wesley WoodAug 26, 2025
  Uneven cutting height with your Toro Lawn Mower can be due to several factors. The blade(s) might not be sharp, so sharpen them. If a cutting blade(s) is/are bent, replace it/them. Ensure 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 if it's dirty. Finally, verify that the tire pressure is correct and adjust it accordingly.
