A well-sharpened mower blade is crucial to maintaining a healthy lawn. Dull blades can leave jagged, uneven edges on your grass, which can make it more susceptible to disease and pests. Moreover, a dull blade can make your mower work harder, increasing the risk of engine damage and injury to the operator. In this post, our team at Dowling Tractor will share some tips for sharpening a mower blade and keeping your lawn looking its best.
Mower Blade Anatomy
First, it’s important to understand the anatomy of a mower blade. A typical blade has two cutting edges, which alternate with each other. When sharpening your blade, you’ll need to sharpen each cutting edge separately. This can be done using a file or a bench grinder, depending on your preference.
Engine Safety
Before starting, make sure that you disconnect the spark plug wire from the spark plug to prevent the engine from starting accidentally. Then, remove the blade from the mower. Most mower blades have a bolt that secures them in place, which can be loosened using a socket wrench.
Inspect After Removal
Once you’ve removed the blade, inspect it for damage. If the blade is bent or cracked, it needs to be replaced, not sharpened. If the blade is in good condition, use a metal file to sharpen each cutting edge. Hold the file at a 45-degree angle to the cutting edge and file in a downward motion. Repeat this process until the edge is sharp.
Balancing
After sharpening the blade, it’s important to balance it. An unbalanced blade can cause excessive vibration, which can damage the engine. To balance the blade, place it on a nail or screwdriver at its center of gravity. If the blade tilts to one side, you’ll need to remove material from the heavy side until the blade is balanced.
Replace the Blade
Finally, reinstall the blade, making sure to tighten the bolt securely. Then, reconnect the spark plug wire and start the engine to test the blade. If everything is working properly, your mower should be cutting grass cleanly and evenly.
