Why won't my Toro GrandStand 74504TE engine start?
- B
  Bethany DaltonAug 14, 2025
  If your Toro Lawn Mower engine won't start, starts with difficulty, or stops running, there are several potential causes: * The fuel tank may be empty, or the shutoff valve might be closed. Refuel the tank and ensure the valve is open. * The choke control could be disengaged; engage it. * A spark-plug wire might be loose; attach it securely to the spark plug. * The spark plug may be faulty; replace it with a new, correctly gapped one. * A dirty air cleaner can cause this issue; service the air-cleaner element. * The fuel filter may be clogged with dirt; replace it. * If dirt, water, or stale fuel is in the fuel system, please contact an Authorized Service Dealer. * If the gap between the safety-interlock switches is not correct, please contact an Authorized Service Dealer.

- K
  Katelyn LawsonAug 17, 2025
  If your Toro Lawn Mower engine is losing power, consider these possible reasons: 1. The engine load may be excessive. Try reducing the ground speed. 2. A dirty air cleaner can cause power loss; service the air-cleaner element. 3. Low oil level in the crankcase can be a factor; add oil. 4. Check for obstructions in the cooling fins and air passages under the engine blower housing and remove them. 5. A faulty spark plug can cause power loss; install a new, correctly gapped spark plug. 6. A plugged vent hole in the fuel cap can be the culprit; clean or replace the fuel cap. 7. A dirty fuel filter can restrict fuel flow; replace the fuel filter. 8. If dirt, water, or stale fuel is in the fuel system, please contact an Authorized Service Dealer.
