A sharp mower blade is instrumental in keeping your lawn lush and well-groomed. These instructions will explain how to properly care for and sharpen the lawn mower blade on your walk-behind. You should periodically inspect the blade adapter for cracks, especially if you strike a foreign object. If you notice dings, nicks or rust on your blade, use a mower blade sharpener to grind a new edge. Replace the mower blade if badly bent or when sharpening is no longer an option. Follow the steps below to safely remove, service and replace your walk-behind lawn mower blade.

Instrukcije

Prepare you walk-behind mower for maintenance
Disconnect the spark plug wire from the spark plug to prevent an accidental start or shock. Turn the mower on its side, making sure that the air filter and the carburetor are facing up.
Remove the lawn mower blade
Start by removing the hex bolt and the blade bell support that holds the blade and blade adapter to the engine crankshaft. Take the blade and adapter off the crankshaft. When removing lawn mower blades, always wear work gloves for protection. The blade can be sharpened with a mower blade sharpener, a file or on a grinding wheel. Do not attempt to sharpen the blade while it is still on the mower. Secure the blade in a vice when sharpening with a file or hand-held grinder. When sharpening the blade, follow the original angle and grind. To keep the blade balanced, grind each cutting edge equally. You may need to sharpen lawn mower blades once a year to keep them performing well. The blade can be sharpened with a mower blade sharpener, a file or on a grinding wheel.
