A well-maintained lawn mower is a gardener’s best friend, and sharp blades are crucial to achieving that perfect cut. If you own a Honda lawn mower, you might have noticed your lawn becoming uneven or your grass being ripped instead of cut. It’s a sign that your blades need replacing. But don’t fret! Changing blades on a Honda lawn mower is a simple task that anyone can do with a few tools and a bit of guidance. This comprehensive guide will walk you through the entire process, from preparing your mower to sharpening or replacing the blades, ensuring you’re equipped to tackle this DIY project with confidence.
A Quick Overview
Changing the blades on your Honda lawn mower is a straightforward procedure that involves removing the old blades, installing new ones, and ensuring they are properly tightened. This guide will provide detailed instructions on each step, including safety precautions and essential tools.
Preparing Your Honda Lawn Mower
Before you start tinkering with your mower, it’s crucial to ensure safety and have the right tools on hand.
1. Safety First!
- Disconnect the Spark Plug: This is the most important safety step. Locate the spark plug (usually near the engine) and remove the wire cap.
- Wear Protective Gear: Goggles, work gloves, and closed-toe shoes are essential for protecting yourself from potential debris or cuts.
- Choose a Safe Work Area: Find a flat, well-lit space where you can comfortably work on your mower.
2. Gathering Your Tools
You’ll need the following tools:
* A Wrench: The size of the wrench you need will depend on your mower model, so check your owner’s manual.
* A Phillips Screwdriver: This is needed to remove the blade bolt cover.
* New Blades: It’s a good idea to have a spare set of blades on hand.
Removing the Old Blades
Now that your mower is prepped and you’ve gathered your tools, you’re ready to remove the old blades.
1. Locate the Blade Bolts
With the spark plug wire disconnected, carefully flip the mower over. You’ll see the blade(s) attached to the mower deck. Look for the bolts holding the blades in place.
2. Loosen the Blade Bolts
Using the wrench, gently loosen the blade bolts. It’s a good idea to hold the blade from spinning while loosening the bolts.
3. Remove the Blade Bolt Cover (If Present)
Some Honda lawn mower models have a blade bolt cover that needs to be removed before you can fully access the bolts. Use a Phillips screwdriver to remove the cover.
4. Remove the Blades
Once the bolts are loosened, carefully remove the blades. Be mindful of the sharp edges!
Installing New Blades
With the old blades removed, you’re ready to install the new ones.
1. Positioning the Blades
Make sure the blades are correctly positioned on the mower deck. The blade’s cutting edge should face the direction of rotation indicated on the blade itself (usually a small arrow).
2. Inserting the Blades
Slide the new blades onto the spindle shaft and align the holes with the bolts.
3. Tightening the Blades
Thread the bolts back through the holes and tighten them using the wrench. Don’t overtighten, as this can damage the blades or spindle shaft.
4. Reinstall the Bolt Cover (If Present)
If your model has a blade bolt cover, reattach it using the Phillips screwdriver.
Final Check and Maintenance
You’ve successfully replaced the blades, but there are a few final steps to ensure everything is in order.
1. Test the Rotation
With the spark plug wire reconnected, start the engine and check that the blades are rotating smoothly in the correct direction.
2. Check for Tightness
After a few minutes of running, stop the engine and re-check the blade bolts for tightness.
3. Sharpen or Replace Blades Regularly
It’s essential to sharpen or replace your blades regularly to ensure a clean, even cut. A dull blade will tear the grass instead of cutting it cleanly, leading to brown patches and a less healthy lawn.
Beyond Replacing the Blades
While changing the blades is a crucial maintenance task, there are other things you can do to keep your Honda lawn mower in top shape.
1. Regularly Clean the Deck
Over time, grass clippings and debris can build up under the mower deck. Cleaning this debris regularly helps maintain optimal airflow and performance.
2. Replace Air Filter
A clogged air filter restricts airflow to the engine, impacting performance and fuel efficiency. Change the air filter as recommended in your owner’s manual.
3. Change the Oil
Changing the engine oil regularly helps prevent wear and tear and ensures optimal engine performance. Check your owner’s manual for recommended oil change intervals.
4. Sharpening the Blades
While replacing blades is the best option for restoring optimal performance, sharpening existing blades is a cost-effective way to extend their lifespan. You can sharpen blades using a sharpening stone or take them to a professional for sharpening.
Final Thoughts
Changing the blades on your Honda lawn mower is a simple yet essential maintenance task that will improve your mowing experience and result in a healthier, more attractive lawn. By following the steps outlined in this guide, you can confidently handle this DIY project and keep your mower performing at its best. Remember, regular maintenance is key to maximizing the lifespan of your lawn mower and achieving a beautiful lawn you can be proud of.
FAQ
Q1: When should I change the blades on my Honda lawnmower?
A: You should change your lawnmower blades every 1-2 years, or sooner if you notice any damage or wear. This is because the blades will dull over time, leading to a less efficient cut and potentially even damaging your lawn. If you notice the blades are chipped, cracked, or bent, it is also time to replace them. Additionally, if your lawnmower is struggling to cut through the grass, it’s a good sign that the blades may need to be replaced.
Q2: What type of blades should I use?
A: You should use blades specifically designed for your model of Honda lawnmower. These blades are designed to fit perfectly and provide the optimal cutting performance. You can find the correct blades at your local Honda dealer or online retailers.
Q3: What tools do I need to change the blades?
A: You will need a wrench that fits the blade bolts on your lawnmower. You may also need a pair of gloves and a tarp to protect your work area. Some models may require a special tool to hold the blade in place while you loosen the bolts. If you are unsure what tools are needed for your specific model, consult your owner’s manual.
Q4: How do I safely remove the old blades?
A: Before attempting to remove the blades, disconnect the spark plug to prevent accidental starts. Then, you can remove the blades by loosening the bolts with your wrench. Be careful not to drop the blades or allow them to come into contact with any sharp objects. It’s a good idea to wear gloves for protection. Once the blades are removed, store them safely away from children and pets.
Q5: How do I install the new blades?
A: Line up the new blades with the holes on the blade shaft. Align the blades so that the cutting edge is facing the correct direction (typically downwards). Then, tighten the bolts using your wrench. You will need to tighten the bolts firmly but avoid overtightening them. Consult your owner’s manual for the proper torque specifications for your specific model.
Q6: How do I dispose of the old blades?
A: It is important to dispose of old blades properly to prevent accidental injuries. Do not throw them in the trash, as they could injure someone handling the trash. Instead, you can take them to a local recycling center or hardware store that accepts metal for recycling.
Q7: What should I do after changing the blades?
A: After changing the blades, you should reconnect the spark plug and start your lawnmower. Run the engine for a few minutes to ensure that the blades are properly installed and the engine is running smoothly. You may also need to adjust the height of the cut to match your desired lawn length.
