Sharpening Your Lawn Mower Blade: The Key to a Perfect Cut
A sharp blade ensures clean cuts and a healthy lawn. Sharpening is an important part of maintaining your mower and should be done regularly.
1. Tools for Sharpening:
- Sharpening stone or file: A specialized sharpening stone designed for lawn mower blades is ideal.
