Understanding the Importance of Blade Removal
Replacing a dull or damaged blade is crucial for optimal lawnmower performance. A sharp blade ensures a clean, even cut, promoting healthy lawn growth. Conversely, a dull blade can tear grass, leaving behind an unsightly, uneven cut and potentially damaging your lawn. Additionally, a damaged blade poses a safety risk, potentially throwing debris or even breaking during operation. Therefore, understanding how to remove and replace the blade is essential for both efficient mowing and personal safety.
Safety First: Essential Precautions
Before attempting to remove the blade, it’s essential to prioritize safety:
Disconnect the Spark Plug
This step is paramount to preventing accidental engine starts during the blade removal process. Locate the spark plug, typically positioned on the engine’s side, and use a spark plug wrench to unscrew it. You can then place the wire terminal securely away from the spark plug to avoid any risk of accidental ignition.
Wear Protective Gear
Always wear sturdy gloves to protect your hands from sharp edges and debris. Safety glasses are essential to shield your eyes from flying objects or debris during the blade removal process.
Allow the Engine to Cool
Before attempting any work on the lawnmower, ensure the engine has completely cooled down to avoid burns. This is especially important after prolonged use.
Tools and Materials Needed
To successfully remove your Honda lawnmower blade, you’ll need these basic tools:
- Socket Wrench Set: A socket wrench set with a 13mm or 17mm socket (depending on your mower model) is essential for loosening and removing the blade nut.
- Wrench: A wrench is used for loosening and tightening the blade nut, especially if you lack a socket wrench set.
- Gloves: Sturdy gloves protect your hands from sharp edges.
- Safety Glasses: Always wear safety glasses to protect your eyes from debris.
- Blade Removal Tool: This optional tool, available from most lawnmower retailers, can help you safely remove the blade.

1. Secure the Mower and Disconnect the Spark Plug
- Place the lawnmower on a level surface.
- Engage the parking brake to prevent accidental movement.
- Disconnect the spark plug to ensure the engine cannot start accidentally.
2. Locate the Blade and Blade Nut
- The blade is typically located on the underside of the mower deck, directly attached to the engine crankshaft.
- Identify the blade nut, a large nut securing the blade to the crankshaft.
3. Loosen and Remove the Blade Nut
- Use a socket wrench with the appropriate size socket to loosen the blade nut.

4. Remove the Blade
- Using a blade removal tool, if available, gently tap on the top of the blade, carefully prizing it away from the crankshaft.
- If you don’t have a blade removal tool, you can use a wooden block or piece of wood to hold the blade in place while you loosen it with a wrench.
- Carefully remove the blade, paying attention to the direction of the blade’s rotation to ensure you re-install it correctly.
5. Inspect the Blade and Replace if Necessary
- Examine the blade for damage or excessive wear. Look for cracks, dents, or uneven wear patterns.
- Replace the blade if it shows signs of damage or is beyond sharpening.
Proper Blade Disposal
Once the blade is removed, it’s important to dispose of it properly:
- Sharpen or Recycle: If the blade is still in good condition, consider sharpening it instead of replacing it.
- Dispose Safely: If you are replacing the blade, ensure it is disposed of properly. Many local recycling centers accept metal blades for recycling.
