Why is my Toro Z Master Professional 5000 engine losing power?
- SStephanie KhanSep 1, 2025
Your Toro Lawn Mower engine may lose power for several reasons. First, the engine load might be excessive, so reduce the ground speed. A dirty air cleaner can also cause power loss, so clean the air-cleaner element. Ensure the oil level in the crankcase is sufficient by adding oil if it's low. Lastly, check if the cooling fins and air passages above the engine are plugged and remove any obstructions.
