Find Your Lawn Mower’s Briggs & Stratton Engine Model Number

The engine details wil be split into 3 groups of numbers

The engine model information is usually stamped directly into the engine or shown on a metal identification plate.

You will find three key number groups:

Model | Type | Code

What the Numbers Mean

• Model – first 6 characters – identifies the engine series 
• Type – next 6 characters – specifies the exact version
• Code – final 8 characters – shows the manufacturing date

If your engine's model number is only 5 digits, you must add a "0" to the beginning to make it a 6-digit model.
