Here's a breakdown:
* Early Lawn Boy models (1950s-1970s) used Lawn-Boy-branded engines, which were actually made by Briggs & Stratton.
* Later Lawn Boy models (1970s onwards) predominantly use Briggs & Stratton engines, with some models featuring Tecumseh engines.
It's important to note:
* Engine type and model can vary significantly depending on the specific Lawn Boy mower model and year of manufacture.
* To identify the engine type in your Lawn Boy mower, check the engine tag or look for model numbers and serial numbers.
* Consulting a Lawn Boy parts catalog or service manual can help you find the engine information for your specific model.
If you need help identifying the specific engine in your Lawn Boy mower, providing details like the model number and year of manufacture will be helpful.
