What Is The Best Way To Sharpen Lawnmower Blades
A bench grinder is the fastest and most efficient means of sharpening your blades, but a handheld angle grinder is inexpensive and a very close second. You can typically find a nice, portable angle grinder for under $60 and it will save you a lot of time filing if you invest in one for sharpening your mower blades and DIY tools at home.
Create A Balance Point
Hammer a 16D or similar nail into a stud in your shed or shop and hang the blade from its center point. In theory, you could simply hold out a nail and do this step by hand if needed. Some blades are harder than others to balance due to the nature of the center hole. The easiest to balance use round holes.
What You Want To Achieve
Ive debated how sharp a mower blade should be many times some will say as sharp as a razor, and others will say as sharp as a butter knife. I like to refer them to what a new blade looks like and ask whether they would sharpen a new blade. In my experience, Ive never seen a razor-sharp new blade.

Position The Mower On Its Side
The first step may seem obvious but weve been around for a whileand weve seen some crazy stuff. In case it isnt already clear, dont sharpen the blade on the mower. For one, it doesnt give you enough room to maneuver the grinder. Secondthe majority of the work needs to take place on the top side of the blade. Third, its dangerous since theres no good way to keep the blade from spinning around on you.
To remove a lawnmower blade, first, get the mower into a safe position. For a gas mower, remove the spark plug wire to ensure the motor cannot fire. Then turn the mower onto its side to expose the blade. Turning it this way helps keep the engine from flooding and oil from leaking.
How Long Should It Take To Sharpen A Blade
The first time you sharpen your blade it will likely take 5 to 10 minutes per edge depending on how bad your blade is. Most of this time will be spent establishing the correct angle. Time will vary depending on the type of grinding wheel you use and how aggressively you grind away material. We suggest small amounts of material removal so as to not overheat the cutting edge. Once you have established the correct angle it should only take a minute or two to sharpen each edge.

How To Sharpen A Lawn Mower Blade With A File
I will start with the simplest method Ive used over the years. Its a technique that never fails with results that have often surprised me with how easy and effective it is. So here are the steps youll need to sharpen a lawn mower blade with a file.
Place the Blade In a Vise
Take your blade and place it in your vise with the edge you intend to sharpen facing upwards and away from you.
Place the Blade on Your Work Surface Using a Clamp
If you dont have a vise, you can alternatively use a clamp. Place the blade flat on the surface again, facing upwards and away from you.
Sharpening the Cutting Edge
Work the file using a long continuous downward motion starting from the blades center. Each pass of the file should extend the blades full length to ensure even metal removal. The angle of the stroke should match the angle of the intended sharpened blade edge this is where you can check your angle with your protractor.
Continue the filing passes until you have achieved the sharpened angle and filed past any chips in the blade. Once complete, remove the blade, rotate it in the vise or clamp, and repeat the sharpening process for the opposite end.

Lawn Mower Blade Sharpening Tool
I generally sharpen the blades for my 60 inch cut mower 5 sets per session. The mower uses 3 blades, so that’s 15 blades. I use a Bench grinder but holding them while sharpening is a tiring, difficult job. I thought, “There must be a better way of doing this.” I made this tool which consists of a pair of Vice Grips welded to an adjustable bracket that slides back and forth on a long rod mounted on the front of the bench, below the grinder. It really works good. Sorry I cannot furnish photos of it’s construction, but I would be glad to take some more detailed photos of it if anyone is interested.
