2. Safety Information
Always prioritize safety when handling or installing lawn mower blades. Failure to follow safety instructions can result in serious injury.
- Disconnect Spark Plug: Before performing any maintenance or installation on your lawn mower, always disconnect the spark plug wire to prevent accidental engine starting.
- Wear Protective Gear: Always wear heavy-duty gloves and eye protection when handling the blade. Blades are sharp and can cause cuts.
- Secure the Mower: Ensure the lawn mower is stable and cannot tip over during blade removal or installation. Use appropriate blocking if necessary.
- Inspect for Damage: Before installation, inspect the new blade for any shipping damage.
- Proper Disposal: Dispose of old blades responsibly and safely.
3. Installation Instructions
Follow these steps to safely replace your lawn mower blade:
- Prepare the Mower: Ensure the engine is off and cool. Disconnect the spark plug wire to prevent accidental starting.
- Position the Mower: Tilt the mower onto its side with the carburetor facing upwards to prevent fuel leakage. Ensure it is stable.
- Remove Old Blade: Using a block of wood to prevent the blade from turning, loosen the blade bolt(s) with a wrench. Remove the old blade, washer(s), and any other hardware. Note the orientation of the old blade for correct installation of the new one.
- Clean Mounting Area: Clean any grass clippings or debris from the blade mounting area on the mower deck.
- Install New Blade: Position the new Oregon 95-076 blade with the cutting edges facing the direction of rotation (usually towards the deck). Ensure the star-shaped center hole aligns correctly with the mower's spindle. Reinstall any washers and the blade bolt(s).
- Tighten Blade Bolt: Torque the blade bolt(s) to the manufacturer's recommended specifications (typically 30-40 lb-ft for most walk-behind mowers). Ensure the blade is securely fastened and does not wobble.
- Reconnect Spark Plug: Once the blade is securely installed, reconnect the spark plug wire.

4. Operating Considerations
Once the new blade is installed, ensure it is balanced and properly secured before operating the mower. A properly installed and balanced blade will reduce vibration and provide a clean cut.
- Blade Balance: An unbalanced blade can cause excessive vibration, leading to premature wear on mower components and an uneven cut. If you notice unusual vibration after installation, check the blade's balance.
- Cutting Height: Adjust your mower's cutting height according to grass type and desired lawn appearance.
- Avoid Obstacles: Always clear the mowing area of debris, rocks, and other obstacles that could damage the blade or cause injury.
5. Maintenance
Regular maintenance of your lawn mower blade ensures optimal performance and extends its lifespan.
- Regular Inspection: Periodically inspect the blade for nicks, bends, cracks, or excessive wear. Replace the blade if it shows signs of significant damage.
- Cleaning: After each use, clean grass clippings and debris from the underside of the mower deck and the blade. This prevents buildup that can affect cutting performance and balance.
- Sharpening: The blade should be sharpened regularly, depending on usage and grass conditions. A sharp blade provides a clean cut, which is healthier for your lawn. When sharpening, maintain the original blade angle and ensure the blade remains balanced.
- Balancing: After sharpening or if you notice vibration, check the blade's balance using a blade balancer. An unbalanced blade can cause excessive vibration and damage to the mower.

6. Troubleshooting
If you encounter issues after installing your new blade, consider the following:
- Excessive Vibration: This is often caused by an unbalanced blade or improper installation. Re-check the blade's balance and ensure the blade bolt is tightened to the correct torque. Inspect the blade for any bends or damage from hitting an object.
- Uneven Cut / Ragged Grass: This indicates a dull or damaged blade. Sharpen or replace the blade. Also, ensure the blade is installed with the cutting edge facing the correct direction.
- Blade Not Spinning: Ensure the blade bolt is not overtightened, which can bind the blade. Check for any obstructions under the deck.
