As a home owner with limited mechanical abilities I’ve always just bought new blades, but now I’m going to try sharpening my own with this method. I have all the tools I just needed the knowledge, thanks !
72 yr old female here...I'm going to sharpen a blade before I mow this year. Thanks for teaching me how. I already have everything I need in the workshop.
Hi Johnny! Have used everything from grinding wheels to files and after watching this picked up a 40g disc and sharpened up my mulching blades. Flexibility was great, put a great edge on and am having great results. Thanks for the tips and tricks👍🏼
The lower side is heavier. It's heavier for a reason... I'm sure it was an honest mistake. It happens to me all the time. On a side note. I learned a trick about sharpening blades that are already being used. You can take a marker and mark the side you're sharpening. That will let you know how much of the blade and the angle you're approaching the blade at.
I love the flap wheel like this. Does a great job sharpening. I usually make a pass or two on a new blade. As far as balancing goes. I find once I have balanced it, if I make equal passes on both side it is very close for the remaining life of the blade.
Thank you mr Jonny for teaching us how to save time and money, I asked you about sharpening blades and hedge trimmers a couple weeks ago and you got it covered in no time I really do appreciate it and will put it to work right away!
A home owner here. I recently put 2 new blades on my lawn tractor for the first time and 1 on my lawn mower. Did not pre-sharpen them, but I got to thinking if I should or not which brought me to this video. I am going to pull the blades off and sharpen/balance them before the grass gets to cutting height. Thanks
Following up on this video-2 months later checking the blades and hit 'em again though they didn't show much wear at all. This method works and keeps a good edge!
Cool Video, as a turf teacher that's how we sharpen and balance our blades, but.... Golf Course Super intendents, and some other guys like to use fancy grinders and balancers that I honestly feel is overkill. for Regular lawn care, residential or just your own yard, this way is plenty sufficient enough. Now I use reel mowers on our putting green and driving range, but on our regular centipede/st. aug/ bahia, even most bermuda and zoysia, I have never had a problem with shredding, or discoloration from sharpening the way you do it Mr. Johnny. Thank you, Zach from Mobile Alabama
Thank you sir, as someone in the business I’m looking for ways to properly sharpen blades. Using a bench grinder is difficult to keep the factory edge. Found out from our exmark mechanic I’ve been doing them wrong just sharpening the edge 😬
I sharpen my blades the same way. I did buy an All American Sharpener. It basically holds the blade at the perfect angle and it’s made to use with your angle grinder.
I generally just slap new blades right on the mower. And I use a bench grinder I have at home to sharpen blades. Bad me, I do not balance. I do like the idea of having the portable grinder to sharpen blades out on the job though. Good video! Middle of February, and here in central FL we are getting into the low and mid 80's some days.
@lloydhlavac6807 my dad seans lawns grew up in Longwood and went to lake Brantley and UCF and worked for the Orlando Magic and I’m pretty sure you might know where that is because you are living there and he says he misses it yes byeeeee
I love all of your instructional videos! You are very clear and concise in what you are saying! Thanks for doing that for us who don't know as much as you do.
Lol I thought the same as you guys, I asked myself “have I been doing it the wrong way for years now”? Lol 😂. It would only make since to shave off material on the heavy side to equal the balance but then I though maybe I have been overthinking this 🤪
Man I’m telling you I’m really liking the use watching you use these battery operated equipment. I’ve always said so way it’ll never last. After watching all your videos I’m definitely going to try the battery concept and see how it goes. No gas and less noise and less weight.
I have all the fancy stuff and also have the flap discs. Use them more then the fancy stuff. Just a observation. I also sharpen scissors and shears as a business including mower blades. On the first side you did notice the way you sharpened it with the sparks going toward the edge. On the second side you reversed it so the sparks are going toward the top/thick of the blade and that is correct. Here is why. In your first side you are creating a burr on the bottom edge of the blade so if you dont remove it its not as sharp as it could be but the goal is not to touch the wrong side. On the second side your making the burr go toward the top/thick portion so the edge is sharp no need for removing a burr and that would be correct. You knew you would get a guy like me right haha. Just sharing no worries it all still cuts grass just not hair.
I have the same Milwaukee angle grinder and I believe I have an 80 grit flap disc. I get my blades so sharp you can pretty much shave with them. I love it. So fast and easy. Great video boss!
what model milwaukee is it and also if someone could send me the link to that type of disk in the video that would be great. Also what type of table was that as far as what was being used to sharpen blades on
I use the same thing. Electric Grinder with 40 grit flap disc or Tigers Paw. 🐅🐾 I take off just enough to remove the paint on new blades as well and use a 5 gallon bucket in the field when needed. 👍 Good video, I'm getting antsy. 😄
Check out the all American Sharpener. It’s made to use with the grinder and allows you to get super fast and accurate angles. Can bolt it to your workbench or use in the vise. Couldn’t be happier with it!
I know this is from 2020... the flap disk is the way to go. Take your time and try to maintain the 30 degree angle, which is what most, (but not all), blades call for. Balancing the blades is also important as well as sharpening a new blade. In my experience, they are dull when sold .
Ya, I've been using cutting blades(you call them stones) in my grinders and have always thought they're eating away too much metal. This is a great tip. Goodonya.
Great video, going to try the flap wheel as you suggest. Should extend blade life significantly. I don't sharpen new blades if the balance is good, and put few cuts on first. I mark and mate blades to left, center and spindles and keep track of blade weights as they wear. I also stick to OEM or Oregon blades.
Great video Johnny 👊 I started doing my blades the same exact way last year. I used a stone disk too at first but, like you said it will eat up your blades. I don't sharpen new blades just, throw 'em on 😉 I need to do a better video on sharpening blades . I don't like the one I did a couple years ago 😒
I dont sharpen new blades, but the big reason to use a flap disk instead of a hard grinding wheel is heat, as with light pressure the flap disk will not get the blade too hot, this will not alter the strength of the blade edge. I also touch the bottom edge just a tiny bit to remove any burr. For blades with a star centre, use a piece of round bar to balance on.
I know this is off topic, but i just saw on your shelve the oil filters facing up with the opening up. Maybe put them in bags or face them down on a flat surface that way nothing can fall inside. Mike Detailed Lawn Care Service LLC Wisconsin
I like to get mine razor sharp with the stone wheel then clean up with the flap disk. Always been told I’m doing it wrong when I get it that sharp because it’s easier to chip but I don’t see how else you’d do it and I like the cut quality
Would the 40 grit take too much metal off ? Great video and has encouraged me to sharpen my own thank you . I have 120 grit disc but haven’t been confident. Will have a go 👍🏼
I sharpen my brand new blades - ever since I bought a new blade and the grass heads looked like I mowed with the old one. For some reason new blades need to be sharpened or they don’t cut as clean. 10 minutes you spend grinding will be worth the clean cut every time.
I use the 40 grit, then switch to a 100 or 120 grit. It only takes a few seconds to change to a different grit. I really doubt it makes a difference, but the 120 grit makes the blade look nice.😊
I don't sharpen new blades. I do use the same method. It is good to do it out of the shop. The dust will cause metal to rust that it lands on. Another safety tip is to make sure flammable stuff is out of the way of the sparks. Good video Johnny !

So if time is money by using this machine you going to save time which in return will make you more money.
I bought a 40 grit disc for my grinder and the nut that screws down and holds it does it have enough threads to tighten it because the disc is thinner than the regular grinding wheels. I can't find one with the thickness I need for some reason. Have you ever ran into that?
On another one of your videos you showed a tool to raise up the mower to access beneath the mower deck. Will that tool work on a lawn tractor type mower, or only zero turn type mowers? Thanks.
Hi Johnny, how many strokes would you say you have to do normally to each side of the blade with the hand grinder? Thanks in advance. Love your videos.
Like the video but you miss spoke on which end needed more taken off it was just opposite side the lower side being heavier is the side to take more off of a simple mistake love your videos
After sharpening the one side do you go back to do the back side as well, knowing that it doesn’t have to be like the first side (just a couple of strokes) wouldn’t that add to the edges sharpness?
11$ for vice? It looks like it gets work done. Whats the name of it? Workbench I already found - 100€ for it, yet 45€ for delivery seems to be a bit too much expensive. But thanks for showing the methods. Basically this is one of the reasons why I bought grinder, now it should be a time to make my blades sharp.

Good video. I think he took the balance the wrong way??? It looked like the left side was “heavier” but he took it off the right side. Is that correct? I have never tried to sharpen my mower blades but it looked simple enough not to spend $25 for a new set of quad cut blades.
Hey on those laser edge blades do you have to be in a sandy area? I live in Jacksonville,NC and was not sure if they would work or not. Do you think in your spare time you could research that out for me?

BEST BLADE SHARPENING VIDEO THAT WE’VE SEEN SO FAR...👍
I appreciate it, thanks!
I have watched many videos on mower blade sharpening, and yours is the best! You are a good teacher. Thank you
You are very welcome
I sharpen my blades the same way. I did buy an All American Sharpener. It basically holds the blade at the perfect angle and it’s made to use with your angle grinder.
Jim B just ordered one myself
Mays lawn care you will love it. Just make sure you get the right model for your needs.
I have the RBG and American and flaps. Flaps are fast. All American is perfect with the flaps. RBG takes off way to much its like a grinding wheel
Dandy Lawn and Maintenance and from what I understand RBG cost like $600. The All American I got was I think $160.
I'll check them out, thanks 👍

I thought the lower side of the blade when balancing was the heavy side not the high side
I looked down here to find this comment specifically lol
You are correct.

i give the blade a thumb nail test if it scrapes the nail its sharp if it do not scape the nail i sharpen it .the blades come blunt for some reason

Question what dealer do you usually go from 5 year’s ago?
I would suggest a few light passes on the opposite side to knock off any burrs that may have kicked up.

Hi Johnny, how many strokes would you say you have to do normally to each side of the blade with the hand grinder? Thanks in advance. Love your videos.
It really depends on the dullness of the blade, thanks!
How often should I be sharpening my blades. And how long until I would have to replace the blade after sharpening it too much
It depends on the type of turf, the amount of properties, and the frequency of service visits
