Can I Sharpen My Own Lawn Mower Blade

I actually enjoy sharpening my mower blades. But I find the most mundane part of the process to be removing the blades from the mower. If you have a push mower, you will want to drain its gas, turn it on its side, secure the blade from spinning, and use a socket and ratchet to remove the nut holding your mower blade in place.
If you have a riding mower, you will need to jack it up to access the bottom of your mower deck and remove your blades. The Home Depot recommends you fix your blade in place by wedging a 2×4 between your blade and deck, then clamping the board to the deck.
I have seen some mower mechanics slip a length of wide-diameter pipe over the end of the mower blade, then hold the pipe in place with one hand while using the other hand to spin the ratchet loosening the nut holding the blade in one place. But I feel that clamping each blade in place is safer mower maintenance for an amateur like me.
Finally, you may need some penetrating oil and even a breaker bar to remove your blades if they have been rusted in place for a while.
Attach The Star Hole Blade Balancer Adapter:
To attach the star hole lawn mower blade balancer adapter, first find the right side of the blade. This is typically the edge with the sharpest point. Then, line up the holes on the adapter with the holes on the lawn mower blade.
Once the mower blade holes are aligned to the adapter holes, insert the adapter through the holes to secure the adapter to the blade. After the adapter is attached, your mower blade is now ready to be balanced.

Remove And Clean The Blade
Once youve determined that you need to sharpen the blade, its time to remove the blade from the lawn mower.
Before you begin, disconnect the power source from an electric mower, whether battery or corded. Disconnect the spark plug wire from a gas mower. This protects you from any surprise hiccups of power. Follow these steps to remove the lawn mower blade.
- Put on work gloves and protective eyewear for safety.
- Drain the gas tank to avoid fuel spills.
- Carefully turn the mower on its side. Be sure that the air filter and the carburetor are facing up.
- Find the nut that holds the mower blade to the drive shaft. Use a ratchet and socket or a wrench to loosen the nut until the mower blade releases.
- If its tough to grip the nut, get more leverage. Brace the blade with a piece of scrap wood and clamp the blade still. You should be able to remove the nut now.
- If the nut and threaded shaft are rusted or stuck together, apply penetrating oil and allow to sit for a few hours.
- Clean the blade with a dry rag or microfiber cloth before sharpening it.
- Sometimes the blade is unusually dirty or caked with grass clippings. When thats the case, spray it with some penetrating oil. Let it sit as directed, then scrub the debris away with a stiff brush.
Check The Blade Balance
The next step is to check the blade balance. When you do this, you essentially need to figure out which side is the heaviest.
If you notice that one side appears to dip then this tells you that it needs to be altered which will balance the blade. In some cases, you might notice that the blade doesnt dip to either side which tells you that its already balanced.

Why You Should Balance Lawn Mower Blades

If youre serious about ensuring your mower operates properly, learning how to balance blades can be done in no time.
To balance your blade, first turn it upside down. Hold the blade in the up position with the sharpened end pointed up. If youre using a larger, step on each corner of the bagger, making sure that the teeth are touching the ground. If youre using a riding mower, step on both sides of the rear wheels, making sure the teeth are parallel to the ground. This step may seem redundant, but it can save you time and frustration if you can ensure your blades are perfectly balanced before you start sharpening.
The second step in how to balance lawn mower blades is to hold the tool vertically. Check your mower to see how far it swings back before you start pulling the string tight. If you find yourself pulling on the string too hard, you should ease off the force. Otherwise, youll damage the mower.
The final step involves the use of a blade holder. If youve been keeping your mower for a while, you probably have a single blade holder thats located on the heavier side of the engine. If not, you should try replacing the blade holder with a new one.

Know When A Blade Replacement Is Necessary
There is a difference between dull, slightly chipped blades that need sharpening and ones that need to be replaced. Every time you go to sharpen your blades, you need to assess your blades to see if they are ready to be trashed.
- Large Nicks: A nick here and there is okay, as long as it can be easily smoothed out during the sharpening process. On the other hand, once there is a nick or dent large enough that regular sharpening will not smooth away, the blade is damaged and should be replaced. With a nick or dent, this can cause the blade to become imbalanced. As stated earlier, an imbalanced blade can ruin your lawnmower. Also, nicks that cannot be smoothed out can increase in size as you mow.
- Worn Blades: Once a blade has become so worn that you no longer can get a sharp edge with a grinder or file, the blade has become too old and needs to be replaced, which may not be recognized with mere looking at the blade, but may become evident as you try to sharpen it.
Making sure your mower blades are in excellent condition is crucial to having a great-looking lawn. By doing this annually, your lawn will be greener, and your lawnmower will last many more seasons as a result!

The reason you sharpen the heavy side is because sharpening it takes off pieces of the blade, making it lighter. You want it to weigh the same amount as the other half of the blade.
Once youve sharpened the blade, hang it back up. You might have taken off too much, or not enough. Repeat the process until it hangs evenly.
