Brief Overview
Removing a blade from your Husqvarna lawn mower is a relatively simple procedure once you understand the steps. The process primarily involves disconnecting the spark plug, using a wrench to loosen the blade bolt, and carefully removing the blade. This article will provide detailed instructions and safety tips to ensure a smooth and safe blade removal process.
Getting Ready for the Task: What You’ll Need
Before you start, gather the following tools and materials:
- A wrench – The size required will depend on your specific model. Consult your mower’s manual or look at the bolt holding the blade in place to determine the appropriate wrench size.
- Work gloves – These will protect your hands from sharp edges and potentially rusty parts.
- Safety glasses – Protecting your eyes from debris and potential blade fragments is crucial.
- A flathead screwdriver – This is necessary for disconnecting the spark plug wire.

- A torque wrench (optional) – This is recommended for tightening the blade bolt to the correct specifications, ensuring optimal performance and safety.
Step-by-Step Guide to Removing a Husqvarna Mower Blade
Now, let’s break down the removal process into manageable steps. Remember to prioritize safety throughout the entire procedure.
1. Prepare the Mower for Blade Removal
- Turn off the mower and ensure it is completely shut down.
- Disconnect the spark plug wire by pulling it off the spark plug. This prevents accidental ignition while you work.
- Turn the mower on its side to provide better access to the blade. This should be done on a flat surface to prevent the mower from rolling.
2. Accessing the Blade
- Locate the blade bolt underneath the mower deck. It is typically a large, hexagonal nut.
- Clean the area around the blade bolt using a rag or cloth to remove any debris or grass clippings. This will make it easier to see the bolt and ensure a clean working space.
3. Loosening the Blade Bolt
- Place the wrench onto the blade bolt and start turning it counterclockwise. This will loosen the bolt, but you might need to apply significant force depending on the blade’s age and tightness.
- Use a breaker bar or leverage if necessary to break the bolt free.
- Do not use excessive force. If the bolt resists loosening, it’s better to investigate further. It might be stuck, or there could be a problem with the mower’s assembly.
4. Removing the Blade
- Once the bolt is loosened, carefully lift the blade away from the mower deck. Be mindful of the blade’s sharp edge and wear gloves for protection.
- Hold the blade securely while you remove the bolt completely.
- Clean the blade thoroughly, removing any accumulated grass, dirt, or debris.
5. Inspecting the Blade
- Examine the blade for damage like cracks, bends, or excessive wear.
- Inspect the blade mounting hole. If there are any signs of damage or wear, consider replacing the blade.
- Sharpen the blade if necessary. A dull blade will result in uneven cuts and increase strain on the mower’s engine.
Installing a New Blade
Once you have removed the old blade and cleaned the area, installing a new blade is a straightforward process:
- Align the new blade with the blade bolt hole on the mower deck.
- Slide the new blade onto the spindle and ensure it’s securely positioned.
- Replace the bolt and hand-tighten it.
- Use a torque wrench (if you have one) to tighten the blade bolt to the correct specification. This ensures that the blade is properly secured without being overtightened. Consult your mower’s manual for the recommended torque setting.
- Reconnecting the spark plug wire.
Tips for Maintaining Your Husqvarna Lawn Mower Blade
- Regularly inspect the blade for damage and sharpen it as needed. This ensures optimal performance and safety.
- Use a blade sharpening guide for even and accurate sharpening.
- Replace the blade if it shows significant wear or damage.
- Store the blade in a safe place, away from children and pets.
Troubleshooting Blade Removal Problems
While removing a Husqvarna blade is usually straightforward, sometimes you might encounter challenges:
- Stuck bolt: If the bolt is very tight or rusted, apply a penetrating oil to loosen it. Give it some time to soak in before attempting to remove it.
- Stripped bolt: If the bolt is stripped, you may need to use a bolt extractor or drill it out. This is a more advanced task, so it’s best to seek professional help if you’re not comfortable performing it.
Safety Precautions: Remember These Tips
- Always wear safety glasses and gloves when working on your mower.
- Disconnect the spark plug wire before performing any maintenance on the mower.
- Never work on the mower while it is running.
- Use proper tools and techniques.
- Inspect the blade for damage before and after each use.
