Sharpening the Blade for Optimal Performance
A sharp blade provides a clean cut and a healthy lawn. Here’s how to sharpen your new or old blade:
Sharpening the Blade:
- Secure the blade: Use a vise or other secure method to hold the blade in place.
- Use a sharpening stone: With the blade secured, move the sharpening stone along the cutting edge at a consistent angle.
- Maintain a uniform edge: Aim for a sharp and even edge along the entire length of the blade.
Important Considerations:
- Sharpness is crucial: A sharp blade cuts cleanly, while a dull blade tears the grass, causing brown spots and unhealthy growth.
- Angle Matters: The angle of the blade determines how it cuts the grass. Consult your owner’s manual for the recommended blade angle for your Craftsman model.
- Be careful not to over-sharpen: Over-sharpening can weaken the blade and reduce its lifespan.
