Quickest Way To Sharpen Mower Blades - Easiest too 

OK Boomer.

So if I marked my blade then I shouldn't be doing it? Even though I've worked in a welding shop, sharpened batwing tractor mower blades, and worked on heavy equipment?

Sounds like your wife changes your engine oil

@@tjmakings there is a distinct right and wrong way to put on a lawnmower blade so yes if you can’t figure it out with your experience then you should probably get checked for memory loss.

I came here to say exactly that!

It’s great

It's called doing things

It’s called having hair on your balls

On god

Its easy to make fun but when you go to the hardware store and see what they charge for a new blade, you go “thanks daddy-o for the video!”

Thats what i always do

That's what I've always used

Not the way I treat my blades 😂

True, but a blade that is extremely dull or badly nicked takes much more time.

I needed a real grinding disc last time i sharpened mine, first attempt destroyed the flap wheel in short order/ Well the blade was chewed and beat to hell since it hadn't been sharpened in 10 years.... I have a new one on order anyway.

Right! 🤣🤣🤣 You literally can't mess it up.

Want it square not sharp he did it wrong

​@@justinburcaw1426 I wouldnt say literally so much as hard to mess it up because it can be. Jus saying 🤷‍♂️

@@GetEmGotUm True! (Uses a rock wheel to give it teeth for Halloween.) 😬

@@justinburcaw1426 -From someone who's messed it up before. Forgot to add that 😂

Hi dad

Hi Dad

Hi dad

Whats good papi

He did it wrong . U want it square not sharp.

should be pretty simple. one side too heavy. then grind that down a tad more

he said it at the end. balance it on a nail.

@@lucasbrum5643 hanging it on a nail isn’t going to magically balance it

@@Dank the nail is only an axis to balance on in the center of the blade, too much weight on one side, lower it, balanced

@@kevinmerchan7669 too complicated

My problem is with the comment about an angle grinder being the best as someone who has used a bench grinder since I was a kid to do the same thing I find that remarkably stupid. It is never better to be holding an object and a tool at the same time rather than just holding the object you are trying to sharpen…

@@SuperSpeederCarl put the blade in a bench vice? Then you just have to hold the grinder. I understand where you’re coming from, and personally use a belt sander as well. But everyone likes to do things their way and thinks it’s the best. If it work, it works!

@@SuperSpeederCarl I wear boots and step on the blade elevated up on a block or bucket to use both hands on the tool like I do daily building red iron buildings. I've seen more numbers and more horrific accidents from bench grinders than angle grinders but I guess the less intuitive the person the more likely to harm oneself with an angle grinder where a bench grinder is harder to have a bad technique

@@SuperSpeederCarl exactly

That’s not even a costly, big deal. Marking the blade you can do with out a sharpie. The bigger issue is showing the world on a RU-vid video how to sharpen a lawn mower blade against the rotation of the angle grinder. It’s not the end of the world, people make comments, I personally don’t even remove the blade while sharpening, I can sharpen it good enough with it still attached to the lawnmower.

Agree. What I've learned in the comments is that men abuse us if we don't know anything, to inflate their ego. I get the 'stick it on a nail' part. What's missing is keep filing the side of the blade that tips it down. File to where each sharpened edge has equal weight & it's balanced horizontally without tilt.

He had to get the blade back on before he forgot which side went toward the lawn

At least he mentioned it. Many videos skip this altogether.

Everybody is now promoting some sort of $100 magnetic balancing aid. Really? A nail works just fine.

I can't be bothered with that. I have only one lawn. It cuts good enough. I don't inspect the cuts to see if the blade is balanced.

Yeah. An old saying. Have the right tools for the job.

What are you talking about?

Yes add a little steak rub on and they will be seasoned to perfection

2030 is the year

Hope you enjoy your lawn when you get it Zora. Nice to be able to go out and work in the garden especially if you have to sit in an office all day.

thanks man, was curious about that part

eis above says he leaves his blades on a nail for 5-7 months to season properly before he uses them.

How do you fix it if it doesn't balance. Do you just grind more off the heavy end?

@@ryan370 yes.

He balanced it incorrectly

I guess there are ppl that really need that balancing test. I can't imagine it would be a few grams off to throw it out of balance unless you really don't know what you're doing.

Balancing isn't required.. you can literally cut a huge chunk off one side and it will be fine. I did it to prove a point on all three of my deck's blades.. been 17 years using the same blades and never an issue

Not a good thing to do, if you hit a rock or a hard object that hardened edge could shatter

I don't think he had them on today.

Good to know but for cutting grass it’s probably negligible

Mower blades are rather soft steel or lightly hardened, as in case of hitting a rock, hardened steel would mean exploding blades and shrapnels flying around, penetrating the shit out of plastic covers etc.

But as a rule of thumb, I agree that using a file/a stone for sharpening any blades is way safer than power tools generating lots of heat.

A few passes with an angle grinder won't heat up the blade.

It probably comes down to what we're mowing. Someone with a push mower and a manicured lawn may be able to get away with filing their blade (singular) by hand. I mow three acres and my mower deck has three blades. I hit rocks and other stuff and my blades end up having an edge that is nowhere near straight. I have to grind quite a bit to get some semblance of an edge back. No way am i going to spend hours filing each blade by hand. But i can see how some people could do that.

Get a sponge kneeler.

A mower blade is a bit different than a knife. My blades look like they've gone to war, but I mow several acres and hit rocks and sticks and whatever else I can.

​@@snorman1911 finally someone with commonsense in that comment section 😂 All that people is talking like they sharpen the mower blade like a chef knife. I think most of that people does not even have a garden to mow.

Firefighters have lawnmower blades in their equipment?

@@lorenzogazzola328 no. Lawn mower blades are similar to the tools utilize by wildland firefighters....depending on the specific tool and usage, are cut at a 15 to 45 degree angle. These hand tools are used to cut line in the brush and grass to create a control line during a wildland fire. Each tool including shovels have specific specs on how and where they are sharpened for max cutting and longevity. Ff handcrews even carry files to sharpen their tools in the field...... Whether it's a pulowski, McCloud, or a shovel, each tool has specific sharpening specs that include such as for shovels..how far up the sides will be sharpened.....this is to protect the ff feet if when digging the boot slips off the shovel..... And yes shovels are used for scraping grass areas and are sharp enough to cut small branches like an axe....if absolutely necessary..... although there are more effective tools that are typically used. These specific techniques taught at the academies including USFS

@@lorenzogazzola328 I don’t mow my garden, I grow veggies in them

me 2 😂😂😂

I edge the nextdoor neighbor's sidewalk that is contiguous with mine, because he's lazy and doesn't do it. That line has to be straight, so I will DOMINATE! 🤣

Are you in love with your lawn?

Annealing of steel takes place at 600-700 degrees Celsius. Using a flap wheel will never make the blade rise to this temperature.

Ahhhh to have the time you have. One could only wish

@@justinberry3991 doesn't take all that long with firm pressure in fact I just had to do this took about an hour and a half. It's not as fast as a gender will be but also not nearly as unforgiven if you stall on your sweep or a kid screams from the door.

@ericswenson7504 i just did both my Oregon G5's. I used a cordless angle grinder with 80 grit wheel. Took 30 minutes. Mared them up pretty good but balanced out. Bought them in October 2021 and just now needed to sharpen them. Got another pair coming in the mail tomorrow. They're the G3's. I heard they might be better with the closed chute, not as heavy and not as wide. Probably wont last as long but I'll give them a try.

Slip the blade onto a pin and balance the halves laterally. If one side falls down it’s heavier than the other side so remove more material from the heavier side by sharpening it again. Do this until you can balance both sides. This prevents the mower from vibrating due to spinning around unbalanced weight (the same way that vibration motors in controllers work).

@@disgustedluigi I understand the process myself aswell as it's importance. I just didn't want some random guys unbalanced mower blade flying off. Got to remember that common sense ain't that common

@@MITUK k. I thought you were asking.

Also try to do everything even. Ten grinder passes on the left side and then ten on the right side

@@MITUK Fr tho, I’m worried for the guy who grinds 5 minutes on one side and 2 minutes on the other😭

Sounded like your dad loved grass more than you, wanna talk about that?

@@LasagnaSupreme couldn't even kick a ball around in the yard

@@GreasyReecey shit man, I was just kidding around, I don't how that feels but that's disheartening to hear

Kids stress you out. Grass relieves stress and makes you to where you can deal with your kids

Why?

@@king-su5uc He’s sharpening INTO the edge. One slip and it will catch that blade violently. If you think of the spinning flap disc as a clock face, sharpen around the 1 to 2 o’clock position. Then it’s pulling the metal off not pushing.

He doesn't know he's still sharpening his blades

@@adamtucker117 bruh 😂😭

@@xx_gam3ing_xx 😂

Who gives a shit

Yeah I had been told “butter knife sharp”

This is false , a properly supported razor edge is the best.

Yeah it can also curl the edge a little when the blade hits the grass.

You don't really. If it's a common problem for you, look where you're mowing.

This a joke

Absolutely.

@@dzl6848 Not at ALL. The blade is directly connected to the crankshaft. If the engine is hot, i.e. you just used it, turning the blade ONCE can easily fire up the engine. LOTS of people have lost fingers because something jammed the blade, they turn the mower on its side, pull the blade to free it, and it fires up instantly.

@@uncletiggermclaren7592 how do they start if you don't have the site bar down on the handle and I have old one and I've never had one start by spinning the blade but why would you take the blade off after when it's hot.

@@dzl6848 Look. YES, you can turn the start handle down, and that makes it less likely it can fire up. Do you know how the start buttons work on mowers?. Have you ever dismantled a mower that has been used a lot, and not serviced? Inside their components, they are heavily clogged up with oil, dust, grass . . . they are perfectly capable of carrying a current even though you think you have closed off the switch. And for the mowers that rely on shifting the choke system right out of run-state, this can EASILY get clogged up so that, while it will suffice to STOP the mower cycling, enough fuel/air mix is present to fire the mower back up if the piston works through a compression cycle. And it isn't worth the risk of relying on the off switch, the damage isn't some little slice on the surface of your hand or foot. A mower will tear your hand to pieces. Put "Motor mower injuries into google. The sparkplugs have a very easily removed and replaced connection, and it is for this very reason. If you are going to work on it, it costs you just a tiny effort and you are SURE it can not fire up.

And if she's waiting still tell her you gotta resurface the whet stone and just hide with a beer.

In the beginning you can see his blades supposed to turn counter clockwise, but if he flip it and the blades face the wrong way (clockwise/to the right) he won’t be cutting any grass, but giving them a spanking 🤷‍♂️

@@UrFavDudeOnUtube I have been a professional garden, machinery mechanic for four years there’s no need to mark the blade because you can just tell by looking at it and the fin always goes up towards the mower.

Remove material.

Hit the heavy side with the grinder again, balance and repeat until it’s level

Hang it on a nail and just remove material from the heavy side till it stays horizontal

13 years ago actually...

Your poor yard...

Thank you so much!! I'd been looking through comments, for just this tip. I'd made the mistake of tipping incorrectly and that has been an issue. Thank you again!

@@kklampsia8332 Happy to help! I ran a small engine shop for years and I still enjoy working on them.

Well said. This is what is taught in the military, which is where I learned to look for these types of efficiencies.

Get it as sharp as possible with the correct angle. The sharper, the better. That's the whole point. If the angle is too shallow on the blade, then yes it will dull quickly.

@@danthompson5797 welll but too sharp and it’ll roll much easier

@@The_Justice_Pack rolling just happens from too shallow of a blade angle.

Yeah. I tried that and the blade kept knocking the side. I just buy new ones

What do you when it's time to change the oil?
