Maintaining your Toro lawn mower ensures a well-manicured lawn and extends the machine’s lifespan. A crucial component in this maintenance is the spark plug, which ignites the fuel-air mixture in the engine. Selecting the correct spark plug is vital for optimal performance.
Recommended Spark Plug Types
Toro lawn mowers utilize various engines, each requiring specific spark plugs. Here’s a list of commonly recommended spark plug types for different Toro models:
Briggs & Stratton Engines: Often found in Toro mowers, these engines typically use the Briggs & Stratton Part #692051 spark plug.
Honda Engines: Toro mowers equipped with Honda engines generally require NGK BPR5ES spark plugs.
Kohler Engines: For Toro models with Kohler engines, the Champion RC12YC spark plug is commonly recommended.
Always consult your mower’s owner manual or contact a Toro dealer to confirm the appropriate spark plug for your specific model.

Safety Precautions
