Maintenance Tips For Lawn Mower Blades
Maintaining your lawn mower blades ensures a clean cut and healthy lawn. Here are key practices for keeping your blades in top shape.
Cleaning The Blades
Cleaning the blades after each use prevents grass buildup and rust. Follow these steps:
- Disconnect the Spark Plug: Always disconnect the spark plug before working on your mower.

Clean blades perform better and last longer.
Sharpening Guidelines
Sharpening your mower blades keeps them effective and healthy for your lawn. Stick to these guidelines:
