Step 2

Locate the Model Number

As shown in the Where to Find Your Lawn Mower Engine Model Number video below, the engine model number is generally a number stamped into metal directly on your engine.

Some push mower engines come with a cover or "shroud". It should be noted that these covers come in a variety of colors, sizes and shapes. Regardless of your cover,
the engine model number will be in one of 3 locations:

Above the spark plug

Tools you may need: •Flashlight
•1/4" or 5/16" socket or screwdriver

On the front of engine

Stamped on metal plate in between the overhead valve cover (OHV) and the air filter.

Above the muffler

Stamped on the sheet metal above the muffler, which can be on the right or left side of the engine.
