How to fix a Toro 22187 Lawn Mower when the engine does not start?

  If your Toro Lawn Mower engine doesn't start, it might be due to an empty fuel tank or stale fuel in the system. Try draining the tank and refilling it with fresh gasoline. Also, ensure the throttle lever is in the Choke position. Check that the wire is securely connected to the spark plug. Inspect the spark plug for any pitting, fouling, or incorrect gaps, and adjust or replace it as needed.

  Sarah MillerAug 8, 2025
  Your Toro Lawn Mower might be vibrating excessively because the blade is bent or out of balance. Try balancing the blade, and if it's bent, replace it. Also, check if the blade mounting nuts or engine mounting bolts are loose and tighten them. Make sure to clean any clippings and debris from the underside of the lawn mower deck.

Why does my Toro 22187 Lawn Mower engine start hard or lose power?
- M
  Michelle KellyAug 12, 2025
  If your Toro Lawn Mower engine starts hard or loses power, the fuel tank might contain stale fuel; drain it and fill with fresh gasoline. The fuel cap vent hole could be plugged, so clean it or replace the cap. A dirty air filter element can restrict airflow; clean the pre-cleaner or replace the paper air filter. Remove clippings and debris from the underside of the mower deck. Inspect the spark plug and adjust/replace it if needed. Also, check and replenish or change the engine oil if it's low or dirty.
