If you have to mark which way the blade goes you have no business removing or sharpening one.
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!
The most DAD video I’ve seen all week
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!”
I spent 2 years at a saw shop. You can sharpen a lawnmower blade pretty fast with nothing but a flat file
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.
My Dad told me to do most of what you did, but when it came to the angle grinder he just said "grind the shit out of it and when it looks like it's sharp, it's sharp"
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 😂
I’m a dad and this vid is right up my alley 😂😂
Hi dad
Hi Dad
Hi dad
Whats good papi
He did it wrong . U want it square not sharp.
Flap discs are one of my all time favorite tools. They make so many types of jobs go so much faster.
Next video idea: How to balance your mower blade after sharpening it
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
Man people in the comments don’t like him marking it. It’s his own mower, he can do as he pleases. I typically sharpen a few blades all at once for neighbours etc so mine are all labelled up cuz we’ve all got different blades… and I’m looking to avoid messing it up. Even if there’s only one way to put it on I like knowing it’s right when putting it on rather than fumbling around.
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 TH-cam 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.
The last part about balancing seemed really important and was really brushed over
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.
Including more information about the nail and how to balance the blade maybe helpful information as well.. so for those who are unfamiliar, here is my quick two cents. Once on the nail the blade should sit at or near level. If not, remove small amounts of material from the blade on the low side (the side that is lowest) until it is at or near leave. If you skip this step you will have a vibration. If the balance if way off it's possible to damage your mower.
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.
As a former municipal mechanic I would use nothing more than a bench grinder followed up with a double bastard file. The Parks department loved me so that they would line up and wait for my service.
Not bragging~ just showing you proper tool selection is where the success lies...
Yeah. An old saying. Have the right tools for the job.
Love your advice and content on ALL of your past DIY yard care vids. I'm in Tampa, and have rehabbed my yard based upon your info. My neighbors are amazed at the transformation. Still battling torpedo grass. Don't forget to correctly torque the blade mounting bolt. Thanks again!!!
Glad you mentioned balancing the blade -- if you're not going to do that step, just buy extra blades and have the neighborhood shop sharpen and balance the blades.
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
I like to leave my blades on a nail for 5-7 months to season properly before I use them
What are you talking about?
Yes add a little steak rub on and they will be seasoned to perfection
I've always sharpened to slightly sharper than a butter knife. Razor or even cutting knife sharp chips much easier if you happen to pick up any debris and that's plenty sharp enough to cut and not tear.
I sharpened the blades on my mower for the first time since owning it (2 years). Such a satisfying cut now.
I don't even have a lawn. But I am so ready for this in the future.
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.
I just did mine Friday. Agreed, it was easy.
You are sharpening it wrong way, the grinding wheal that you are using will kick back when rotating against the blade, it has to rotate away from the blade, when sparks are flying away from the blade you know that the direction is right and you will not destroy the grinding wheal. Bless you
the best way to sharpen a blade is by hand and use a file. this allows you to feel as well as see any of the deformities that are needed to be dressed. every firefighter is taught this throughout their career on every hand tool.
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
I used Lincore 55 hard facing weldwire and put super hard edge on mine then resharpened it. Never needed to resharpen after that.
Not a good thing to do, if you hit a rock or a hard object that hardened edge could shatter
File the blade sharp rather than grind with power tools.
Keep the steel cool rather than generating heat, destroying the temper.
Filed blades will maintain the edge longer.
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.
Flap wheels are kind of amazing. Great tool for many uses
If you color the edge with the marker, you make sure you have the correct angle.
Perfect timing for this vid for me as I am noticing the same problem! Gonna grab one of these discs for my grinder! ✌️
This might be some “dad” content. But being 20 years old and a first time home buyer I have to dominate the neighborhood! 😎
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! 🤣
All I think about is lawn care.,.

Are you in love with your lawn?
You really do not want your mower blades razor sharp then your at risk of chipping the blade 👍 hope this helps
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.
If the sparks are flying away from you, your days are numbered my boy
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.
My knee hurts just seeing yours on the concrete 😅
Get a sponge kneeler.
Always disconnect the spark before beginning any lawn mower maintenance.
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.
Hey! It's Alan from Cleetus' videos! I knew you had a channel but it's neat to find your shorts!
I don't think he had them on today.
That balancing step really got breezed over
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😭
I seriously wish I could get my yard looking nice enough for this to be an issue.
me 2 😂😂😂
Some use a balancing spindle or pyramid shaped balancer, but I use a nail or screwdriver, & those have worked out well for me as long as they are evenly parallel with the ground.
Spin it slowly a few times, then when the blade stops level, it is balanced close enough.
I've sharpened my blades like this for years, but only recently realized the importance of the cutting angle. My blades gradually worked themselves to a 45 degree cutting edge and didn't cut well at all anymore. I reworked the edges to 35 degrees and wow! A cheap digital angle finder is the way to go
Dads love grass more than their own kids
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
If your wife wants to have a talk after you're done a hand file and whetstone is the preferred method.
And if she's waiting still tell her you gotta resurface the whet stone and just hide with a beer.
Thank you!! I really appreciate this education and detailed instructions! It does look simple and I don’t think there is any harm in identifying the direction of the blade; that’s a good thing!🥰
I have that makita grinder. Use it in a truck shop and it has done a great job for me, I love it! Good advise thanks!

I personally use my hand metal file as I enjoy the motion and find it more forgiving if I hiccup on a stroke as my kids and pets have taught me I'm never alone in my shop
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.
Best way I’ve found.
I am so glad to know that my family and i do not sharpen our mower blade only because a while ago my younger brother was mowing on an elevation and he slipped and slid foot first into the mower blade and thankfully it was just a scary big cut on the side of his bigtoe and not even a break or fracture, if that blade was sharpened i couldn't imagine what would have happen that day if that blade was sharp.
OH MY GAWD MY GRASS ISNT PRISTINE WWAAHHH
Never sharpen to a razor edge. If you don't leave a landing on cutting edge you will chip your blade making it harder to sharpen next time and the easiest way to unbalance your blade is to sharpen it with a grinder. A file works just fine, and doesn't aneal your blade
Annealing of steel takes place at 600-700 degrees Celsius. Using a flap wheel will never make the blade rise to this temperature.
Just did this today! Used a Makita grinder, too! Grass cut and looks great!
My grandfather used to own a True Value hardware store. He taught me how to sharpen lawnmower blades and I got so good at it his customers would request that I do it for them. It was fun too. I used a bench grinder with two different wheels though
I used to be a technician at a landscaping repair company I was basically a mechanic for landscaping equipment one of my favorite jobs was sharpening lawn mower blades and my boss always wanted me to do it as quick as possible and just get it done it doesn't matter if it's actually good and sharp or not but I found that if I polished the blades and actually spend a decent amount of time going through the grits the blades would last significantly longer and give him much better cut so if you ever have the time and want to see an increased life on your blades and much better-looking long go through the grits and finish on a buffing wheel with some compound and get the blade really shining and make sure to do both sides the beveled side and the convex I'd just to make sure you get rid of the bar and give the blade proper cutting angle and you won't be disappointed it takes like an extra five minutes at most and it's worth the time
Glad to see that you made it through the hurricane. I hope that you’re doing OK.
Got mine sharpened today! Thank you for the motivation!
Glad he said balance the blade
Super helpful, I have the same Grinder and flat disc. Will try your method. Thanks!
That might be the fastest way but nothing beats the satisfaction you feel using a good old file
Great stuff I’m sure you helped many!!!
That moment when you haven’t sharpened your mower since you got it 15 years ago
13 years ago actually...
Your poor yard...
Might be the one man who sharpens his mower blade I've ever seen. My dad has been using the same blade in his mower for over a decade. Then again we've never felt the need to inspect the grass with a caliper and shit
Unfortunately im dangerously clumsy so angle grinders are not compatible with me, but the video still makes sense thanks!
If you change your mind, sanding wheels as an attachment are relatively harmless and do accelerate work, and I recommend getting a grinder with a momentary switch (which stops as soon as you stop applying pressure to it) as those are a lot safer in the event you lose grip or drop it.
There’s no need to mark the blade, because the fin will always go up towards the mower
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.
#1 Rule of sharpening tools with abrasives, never, never ever sharpen towards a sharp edge, always away. Otherwise you will eventually launch the tool across the shop.
This is hands-down the best way to sharpen a mower blade... Do this twice a season for most lawn sizes.
I use this method as well. It creates less heat than a grinding wheel. Once you heat up a blade too much, it looses its temper and won't keep sharp very long. Good diy tip.
Mower blades don't stay sharp long anyway, so overheating a little won't matter.
"today I'm going to teach you how to cook the heat treatment out of your mower blade and leave a bit on it, so it's also a rough edge that will catch. I hope you enjoy having to sharpen more often."
Marking the blade is correct. It might be unnecessary but costs similar to taking a sip of water or coffee and the pay off is not having to think. Whenever you remove conscious thought as a portion of a chain of physical or logistical events then you strengthen that chain. If you think you're too good for a move like this you're worse than useless for building or fixing things.
Well said. This is what is taught in the military, which is where I learned to look for these types of efficiencies.
Thanks a lot for this video, I have both of those items will let you know how it goes.
There’s gotta be someone who will fab up some super awesome hardened steel blade or something that will stay sharp for long time if you’re this much of an enthusiast
Finally, somebody else that uses a grinder to sharpen things... obviously not knives but all my garden equipment is either flap wheel or grind wheel sharpened
This is the most dad content on youtube
this helped. i started a mowing business.
in the middle of grinding the blades, a man came up and told me I was doing it wrong. he did it the same way you did and I did. 😂
wtf did I do wrong?
anyways, thanks for your videos. learning as I go.
Always tip the mower so the spark plug is in the air. If you tip it any other way, the oil can find its way up there and foul the plug. Also, no need to sharpen past the first 3 inches of the blade. It spins at about 3000 rpm, so grass never touches past that point. If it doess, address the poor running motor. (small engine mechanic with 30 years experience)
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.
Get MagnaMatic to sponsor you. Now we are talking sharp and balanced blades. Check ‘‘em out. Precision equipment.
Exactly how i do it 👍
And yes i know how to sharpen tools and blades on stones, but i would never take something that crude to my sharpening stones. It takes forever just to hit some pebbles in my lawn after 5 minutes og mowing
Anyone that told you to use a stone on your blade is a moron. A good sharp file is great though.
First Aussie 😁. Lawn Care Service Announcement. 🤠
Wife: he’s probably out cheating. Him
That was smart of you to pull the spark plug boot off so the mower couldn’t fire up by accident
How do you switch off a mower ... what does it do ?
@@DreStyle it doesn’t allow the spark plug to fire so it won’t start up
i sharpen a lot of blades with angle grinder. Such a classic.
never sharpen it to a razor sharp edge. Sharpen it until it's butter knife sharp. That's how it should be done.
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.
How do you balance it take material off or add weights like a wheel🤔🤘👍🎥
Remove material.
Hit the heavy side with the grinder again, balance and repeat until it’s level
No. For any newcomers that might see this video, the answer is no. It was never meant to be razor sharp. Its a 45° angle against the edge for a standard blade & 35° for a mulching blade.
You bring it to an edge but it will NOT be razor sharp and if you temper it you done F'd up A A Ron.
Love the K&P reference! 🤣👌🏻
Oh yeah. I need to sharpen mine for the last cuts of the season. The last mow is the most important. It determines what your lawn looks like for 4 months or so.
4 months?! Is that because it snows for that long ? 😮
How do you balance the blade?
Hang it on a nail and just remove material from the heavy side till it stays horizontal
Be extremely careful with a grinder if you've never used one!
Hell yeah i was about to pay someone to sharpen the blade. Didn't think it'd be this easy
Oh, thank you. Now I can do this myself.
pro tip: replace your lawn with a garden.
you spend time with plants they might as well feed you
There’s nothing worse in this world…. than tattered grass tips.
Just be very careful when disassembling the blade and assembling it as you can torque it to the point of it starting or if u move just a little bit of it and the engine is hot it could start up as it is not likely I know people who have and almost caught themselves In it
This is why he removed the spark plug cap granted he didnt mention it aloud, I'm used to removing the plugs entirely having worked around aircraft as it's generally safer since a hot engine can fire up even without the leads attached while the plugs are in. But it ain't gonna run without any compression whatsoever.
Is there a mower made in the last 50 years without a dead man's switch. Y'all sound like the women saying there's someone hiding under your car with a knife everytime you come out the store. Everything's not out to get you.
We call that a "Tiger paw" or "tiger disc".
Use it often at work.
A flapper wheel would be the equivalent but for an end grinder. (at least what I'm accustomed to).
Welder here. Tiger paw is a completely different style of disc. Flap discs are used to bring work pads and couplings down to a very fine and smooth finish and they are little rectangle peices of sandpaper. A tiger paw looks similar except it is not sand paper but a very sharp saw like abrasive. A tiger paw digs and cuts where as a flapper wheel scratches and removes
one day ima need these videos when im a dad 😂
I'm lazy and just buy new blades at HD
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?
Well done, thanks!
As i live in Hawaii mowing my acre of lawn once a week all year round for 4 yrs with the same mower not caring about the blade. Cuts my lawn beautifully. If it aint broke dont fix it.
remember, you only sharpen the top side of the blade, the other side stays flat to meet it at a point.
also, the outer 2.5cm matters most because it does most of the cutting
If you think mower blades are supposed to be razor sharp, you don't know what you're doing.
You don't have to get it razor sharp. Once the blade hits a rock, that Edge is gone. I just usually sharpen mine to the point where it can shave my nail. I can see why you wanted to get razor sharp but when you get that sharp and it hits a rock. You run the risk of it actually chipping the blade. Thought i might give you some helpful advice from experience. Keep on mowing man
The “balance on a nail” got you sooooo many extra views here.
NEVER sharpen your blade "razor sharp" this will cause the blade to wear significantly faster. You want it sharper, not razor
This is completely wrong. Cutting geometry and proper clearance will last the longest. A properly sharpened razor edge is the best.
@@bobalmendinger4930 been doing this for 30 years I believe you sir, are wrong. Stay humble and learn
@@SzymczykProductions why is he wrong
@@rival0823 A razor sharp edge is great for a knife, but with a mower these blades are swinging at very high rpms. Sticks, rocks, or anything hard will chip away a razor edge on the mower blades. You want it sharp, but nothing close to razor sharp. Having a subtle dull edge allows the blades to take more impact and won't wear down your blades as fast but still sharp enough for a clean cut. I hope this helps.
@@bobalmendinger4930 wrong
Thanks for the tip of those blades.
Recognize you from cleetus’s channel. Keep up the good work!
Incredible video never knew about the nail trick! That's going to get me some money someday a long ways away.
