Easy & Quick Way To Sharpen Mower Blades (CONTROVERSIAL)
ฝัง
- เผยแพร่เมื่อ 16 ม.ค. 2024
- This is how I sharpen mower blades. Apparently, since I use a shortcut to mark the blades, some Boomers think I should not even be trying. I also get lawn pros telling me I'm wrong for sharpening to razor sharp instead of butter knife sharp, which literally makes 0 sense to me as a DIYer who only cuts one lawn, the same lawn, weekly.

Check out the pinned comment on this video for the reaction that came the last time I did this th-cam.com/users/shortsb0h_70Avzd8
I could be wrong, but different mowers either do or don't prevent the blade being upside down. My Ryobi electric, at least, prevents improper install by using a crescent-shaped and a round lug on opposing sides of blade hub. Can only go on one way.
I think the only people that pick holes in what you are doing a “lounge chair” lawn mowing people. Everything you said and did was spot on👍
Nothing controversial about a flap disk and angle grinder. I used to hand file, then got a grinder with a regular wheel, then got a flap disk after one of your videos. Much more control on material removal than a grinding wheel and you get razor sharp every time. I put mine in my vice though.
A vise does make you look more professional than a pair of gloves
One problem with angle grinders, specifically with flap wheels is that it rounds over your blade edge, which isn’t ideal but if you have a unsharp blade to begin with that’s better than nothing
@@KDlGG It will give you more of a convex grind instead of a flat or hollow grind. Though for the purpose of cutting grass, it does just fine. I do take a flat file to the underside of the blade to shave off the bur when I'm done. That makes a huge difference.
I been sharpening my mower blades with an angle grinder for years, the only difference is I put my blades in a bench vise while sharpening them. I have a couple of sets for my zero turn and my push mower, swap them out every couple of weeks during the summer.
Great video, keep ;them coming.
Thanks bro!
I appreciate your down to earth explanation and honesty. Even saying that sometimes you get careless. 😊 Who doesn't? Thanks !
Thanks from a fellow who was afraid to do it himself, these videos help a ton. I sharpen using your method, and it's been working out amazingly. Typically, I wouldn't comment on a video, but I've taken on sharpening mower blades, fixing simple sprinkler issues, and laying down products without fear of killing my yard. Even took a shot at Christmas lights this year. Very grateful and appreciative of your videos, and really hope you continue to make them and ignore the negative comments.
that's awesome Alex! I hope you are enjoying the journey along the way too! enjoy the mow, bro!
I love how you presented this in a user friendly, don’t be afraid way. I’ve never thought about it before but you’re right, most homeowners probably never sharpen their blades and buy a new mower or take it to a shop because there’s is cutting like crap after 3 years of running the same blades that have chips or divets.
Great tips Allyn 👍 The EGO mowers have that small hole that was at about one o'clock position on your mower that you can put a rod or screw driver in to stop the blades from spinning when loosening or tightening - so you don't have to hold the blades with your hand.
I learned this method from you a few years back in an older video. Great method…Works great and it’s super simple.
No criticism from me you’re awesome in my book and we need more people like you
I finally bit the bullet and bought the All American Blade Sharpener and was the best investment I could have made. Quick and easy and the sharpness and angle is spot on.
Great choice, this will ensure you keep the correct angle, while you are it get a proper balancer (they are pretty cheap), lot of variation with the nail. There are videos out there showing how far off the nail method is.
I don’t have a grinder. What’s about the stone you attach to a drill?
@@user-ue8ce8vu8s You use grinder flap discs.
@@user-ue8ce8vu8s crap. Go buy an angle grinder.
“Some people call it a Kaiser blade, I call it a sling blade…. Mmmhmmm
I found this method earlier this year and now so much easier to keep them sharp. Previously it was a metal file and slow process to get the same result with the sanding disc on the grinder.
Awesome video, as per usual Allyn! I was among those that was intimidated by it at first, love doing it now! I do tighten to torque specifications, but that’s just me to avoid stripping the bolts.
I like that high tech blade balancer, you'll never miss place it,
Always learning from The Lawncare Nut. Stay warm, Allyn!
Thanks for the detailed video. I had shied away from sharpening my blades and just bought new ones when I needed to, mainly because a lot of other TH-camrs break out their vice on their fancy work bench and I don’t have room for all of that in my garage. Good to know I can use cinder blocks to accomplish the same thing.
I’m of the opinion that new blades at the store are DULL. They barely look sharp enough to cut butter. They do that for liability issues. Take them home and get them razor sharp. Your grass is healthier without the fray, and its this fray that gives the lawn that brownish tint in mid summer, even if the grass is green.
Great video as always! I’ve found the flap discs are excellent at sharpening mower blades. They make the job fast, simple and effective. If I may, I’d like to offer two suggestions for your next blade sharpening video, regarding safety, which may prevent someone from losing fingers. For battery powered mowers, it’s important to remove the battery pack before tilting the mower over. For gas powered (petrol) mowers, it’s important to disconnect the spark plug cable before tilting the mower over, and always tip it over with the carburettor facing upwards. Cheers!
Carb up is a must.
You go and enjoy the mow, and I'll go and enjoy the snow. Just got 5 inches. I'll enjoy it while i can. 8 more weeks til spring!
Very sharp! Love it. You are dressed better for winter than I am in NH!
haha! I only have 2 sweatshirts and this is one of them. 😃
Very well explained always a great show brother
Al- I have the same mower with older (not green) blades and the writing on them IS hard to read, so I’ve taken a picture each time I sharpen so I don’t screw up the reinstall. I’ll mark from now on. Thanks!
Great video as always. People being judgmental... You've always shared options so we could do things our way. I appreciate you and your channel more than you could know. Cheers my friend!
thanks bro!!
lol: “I’m not too stupid, I’m actually careless sometimes!”
Picked up the All American Sharpener and loving it. Also picked up a high quality blade balancer that also checks warp. My grass is loving it.
my neighbor has one of those blade balancers too - pretty cool
To those who criticize about marking the blades I would say this: orthopedic surgeons mark the arm / leg shoulder / etc that they’re going to operate on before they put you to sleep. It’s just the smart thing to do.
love controversies. bring it boss. awsome as usual
good advice on this chilly day...
Bro you might could use a bench vise to hold your work instead of working on the ground. I do some commercial mowing and I like my blades razor-sharp and use the same tools you do. Love the flap wheels. Learned about them in welding school. Good job man!
That's great information thanks Allen 👍
Thanks for the Video, I will start to sharpen my blades from now on, keep up the great work,, from your newest subscriber 👍👍💯
Blades normally will get dull while hitting rocks tree roots or other debris that might be on the lawn. But like you said as a homeowner who walks my lawn daily none of that is on there. So what I do for both my rotary and my reel mowers is use 80 grit sand paper and go over the blade before each mow while the blades are still on. Takes a few minutes and my blades stay sharp. For my reel mower even with 10 blades takes a few minutes and paper test before mowing. When finished I hose it off and then use blower to dry it. Blades unless damaged or nicked usually hold up well.
Yep,I sharpen my blade. Easy peasy lemon squeezy. Another Good video,Al👍🏽
That's the cut I get with my scythe. The peening scythe is always kept razor sharp. The edge is hammed thin against an anvil and is then honed with a specially shaped honing stone that leaves a single, upward facing bevel on the thin edge.
The slicing of grass with a newly honed blade is extremely satisfying. No plastic parts, no fuel, no batteries, no loud noises.
I use a digital torque meter and tighten to the reading in the mower manual to make sure it’s not too loose or too tight. Also gives peace of mind that it won’t go flying off when the engine starts.
lowes has a $6 blade sharpener attachment for regular impacts. it works great for me.
I should go down to Florida and hang out with you guys an mow some grass. We have 1.5’ of snow and it’s been -15 here in northern IL.
I've been a fan of your work for quite some time now, and have learnt a LOT. Just a question... what do you think about cutting your lawn (albeit skillfully / carefully, and with many hours of practice) with a petrol brush cutter (using replacable nylon "sticks" - not a metal blade?). This method (where I live) is super popular and I myself use this method. Thanks for the informative video (as usual!)
I use the 60 grit flapper also. I just hand hold the blade and run the disc on each cutting blade 3 or 4 times and then a fast pass on the back side. Get's em sharp and fast...
Thanks Allyn! I have been watching you for years and went from a complete shithole of a yard, to yard domination, to neighborhood domination, to town domination, to helping others do all of the things that I do now to make their own yards look great. It truly can be a very positive an infectious passion instead of being a burdensome chore. I am one of the weirdos that really ENJOYS THE MOW. While I certainly don't have the biggest lawn in town, I have (arguably) the best one. My kids never have and never will mow the lawn until I am disabled or dead. lol
It is nice to help others to not be intimidated by the process and task of making their own lawns/yards look great and it doesn't always have to start out as an expensive process, it just takes some effort. Having resources such as yourself and others out there, make it easy and enjoyable to gain the knowledge to be confident in the process, and it is invaluable and appreciated.
I can't wait until spring to throw er' down! Salute and thank you! I hope the videos keep coming!
I enjoy the mow, too. My siblings and I used to argue over who would get to mow.
I use a Dremel tool in place of an angle grinder, but I sharpen mine as well. Good video 💪
If you want grass to stop clinging to the bottom of the mower treat it with a special oil and the grass will repel off the metal and it won't stick that worked for my mowers its a mixture of different oils and it won't stick to it at all
I use a file on the back side just to have a little more control on the material I remove.
I highly recommend getting a proper magnetic blade balancer if you haven't already? You are the Lawn care nut after all 👍
4” of snow here and possibly more to come this Friday. It’s going to be a while before we get to mowing. LoL. I don’t blame you for marking. It really is hard to read stuff like that. Idont understand the etching for recycle symbol on those clear plastic containers, especially when the symbolis so freaking small!
It’s not a bad idea to double check the tightness of the bolts after the first use from sharpening.
I didn’t do this and further into summer my blade came out from under my mower spinning like a top in front of the path of the mower. Lucky for me it came out the front side.
“Click” love it! I do it the same way.
We need you to partner with a mower company and co-develop a robot, lawnmower, specifically made for tall, thick grasses, such as Saint Augustine and Bahia grass. This will be the next best thing for you and the Yard Mastery company.
I've looked into it extensively and right now, I don;t have the funds to bring OPE to the market. It's a long ramp and very expensive. Maybe someday I'll find someone who has perfected it already and I can partner with them. Right now, Kress is the best robot on the market IMO but I have not tested one on St Aug. Coming later this year.
Great video. I had one question about your mower. So I have the same model but mine from being out in the weather seems like the bar is stuck and won't let me fold the mower up. My question is do you know how I can fix this? Thanks in advanced.
Good video, only thing it you do it in your driveway you will get rust stains from the metal particles that you are grinding from the blades
Love to see how you do the blades on the ego rider.
I love using the flap disc. Perfect finish ever time.
agreed!
@@Thelawncarenut60 or 80 grit?
@@bigal1419 80 works great
Thats the way I do it same disc and I use a vice for some more precision .
What's a good grinder to get and what kind of pad?
Clicked on this thumbnail thinking it was Matt from The Smoking Tire, and wondering if he’s getting into lawn care now. Same face / hat combo.
Actually got a super cheap mower before because it wouldnt cut for the person anymore even though he got them sharpened. Turns out he just put the blade on upside down 😂.
Flap Disc was my nickname in college
😂❤
I would recommend using a vise to hold the blade while you're sharpening. Otherwise, this is exactly how I sharpen. Very fast and effective.
Allyn, you should do a garage organization project! This begs for a multi-part series like the Xmas light vids.
and certainly needed ha ha!
No toro gear anymore?
I sharpen razor sharp for my zoysia and have to sharpen after 3 mows at the most. I have 3 blades that I sharpen all at the same time on a grinder and then rotate them out as necessary.
I use a flap disc as well and swear by it, but I always worry that going against the blade edge will cut into the flap disc and cause the grinder to fly out of my hands. I go the opposite direction, shooting the debris downward towards me.
Do you know if you can put a second blade on the basic model? My ego mower struggles to cut the grass! It's annoying. If I had known it would be this bad I would have gotten the select cut version.
Toro* I’ve been holding off as much as I can cause they’re so pricey and I want to make the best choice. I saw your older videos you used Toro, and now Ego, but bc your sponsored I wonder what your choice is. I also live in Florida. I hope to hear from you before I end up going with my gut feeling of Ego.
Too cold and too much snow on the ground to worry about my mower in the Kansas City area.
I've said for years when your blades are sharp you can hear them they sound different , ride-on push mower doesn't matter you can hear it.
I’m not even thinking of the mower. More like the snow blower. 😂
Rochester NY.
I do sharpen my blades throughout the season. Same way you do except I clamp them down
I need to try clamping mine - many others do it that way too.
This may be a dumb question but can you do a video on the ego edger? I’ve also got one and have it set for as high as possible but the blade/disc still goes pretty deep into the dirt. Haven’t had one time I haven’t left a trail of dirt behind me. I don’t t know if it’s me, the tool or my height because of the angle it ends up being held (6’ 3”).
Interesting, not something I've had an issue with, but I can for sure do a video because I'm sure there are others who would like to know the advantages of the bladed edger in the first place. I'll include that in one of my upcoming weekend vlogs.
My blades are razer sharp. If I ding something I’ll swap them out on the spot if I notice the cut quality. Very rarely will that happen or ever be noticeable as they are swapped out daily.
I worry about doing this because we have such sandy soil and it eats through the blades. Don’t have to hit rocks and my blade is still dull after a couple months.
Thanks! I like the technique, but mine always seem to go dull pretty fast, like 3 cuts or so, is it blade material?
I'm not sure on that - if you have a lot of sand in your soil, that can contribute to it.
I’ve been using the yard mastery products and just can’t seem to have green grass always playing catchup from bug damage or disease, just going to have to pay professional to treat it.
@thelawncarenut I am a homeowner I sharpen my blade every 6 cuts and use a Dremel, grinding it like you have with an angle grinder it quite aggressive. I do wish you would have mentioned, if you ( the watcher ) have a gas propelled.... you disconnect the spark plug. *** Always remember you have first time homeowners / viewers. If I remember correctly, you have a video with un-plugging the spark plug you could cut to it for 10 seconds. Great informative channel, thank you.
I unplug the spark plug on my gas mowers when I work with the blades. And every time I will forget to put the wire back on. It usually takes more than a couple pulls to 'remind' me. Arrgh! 😮
@@pcolapaddler I do that almost every time. It's a hoot. I am like you ( me ) are an idiot. hahahahaha
But at least we sharpen them.
Wow, I guess I've been doing it wrong for years. I've only been sharpening my mower blade at the beginning of the season, once every year. I do a new plug, air filter, oil change & blade sharpening. I've been doing this for about 4 decades now. Is my lawn suffering from this lack of sharpening?
True Patriot, for sure.
It's 16 degrees above 0 in my yard. I think I'll pass on the lawn cutting. Oh, I forgot about the wind chill...
Make that 2 degrees above 0... LOL!
Wait..whuuut? You mow every 3 days in the summer? Wow..quite the difference from up here in New England. We mow about 1x per week up here.
I thought grass didn't grow as fast during the summer months in FL?
What size grit do you use for the flap disc?
60
OMG, the first thing is about marking the bottom of the blade.... You only need to look at the blade to know which side faces the grass..... Marking the bottom? Ha ! :D
The fact Ryobi uses 2 different size bolts to remove the blades shows the enginerds have never worked on anything in their lives.
I have a ryobi, and yes it’s absolutely dogshit for other reasons but I only have one bolt to remove the blades, what one do you have?
@@KDlGG scag 48 walk behind
@@Ball_drips I meant the ryobi that had 2 different bolt sizes
It's an EGO mower, but I wouldn't expect much in the awareness department given your username.
Allen, any idea why my st Augustine lawn (which is predominantly very lush and green), now has a random section or two of lime green? It’s not due to iron or nitrogen as I regularly apply both…? Any idea given you’re the st Augustine Guru? Haha. Thanks
it happens often, especially after lots of rains in sandy soil. It's also winter so right now it's not happy at all. It will recover once things warm back up - I also have some lighter spots in mine
Do you prefer Ego over Toto ev?
Great Video, "I'm not stupid, I'm Careless!" LOL! There's a difference! Get you a vise bro, you can bolt it down to your work bench.
Nice! Good enough for government work.
Can you do a similar discussion video on gas powered mowers, the issue of oil draining into the carb can be addressed.
Can’t wait for that EGO aluminum deck mower.
me too! hopefully next month it will arrive
Just buy a Chinese knock off of the blade sharpening jig. Works great and you don’t have to worry about the ting the wrong angle.
New LCN t-shirt please: "Not stupid, just careless".
😂
It’s definitely time for a bigger home workspace
Razor sharp baby!
I have a gas mower. Can I sharpen my blades the same way?
Should the blades be torqued a certain level?
yes there is a torque spec listed in the manual but I don;t have the proper wrench
I just bought an ego 765 blower. Never been impressed by a hand held blower.
Now we need to see how it's done on the zero turn...🤔
Allyn you are why I use an angle grinder but Now I have to get a flap disc.....I always feel like if I go back and forth like that The sand paper will fold the wrong way on the flap disc.
Spray some WD-40 on the deck after cleaning. It will help with grass build up.
My only comments - butter-knife sharp and industrial tooling sharp are similar but different - tooling sharp is a squared-edge but is still very sharp. That squared edge will remain sharp a lot longer than a thin/tapered edge. To achieve that squared edge in home tool environment doesn't make a lot of sense... especially when going tapered sharp is so easy.
Also - Nitrile gloves are good for chemical resistance, but not cut/puncture protection... leather is a good idea for handling sharp things like razor sharp mower blades. :)
good stuff thank you Joe!
@Thelawncarenut only reason I mentioned leather gloves is because last year I had to get 4 stitches in my thumb... after my wrench slipped off the bolt and I unintentially manhandled (my nickname in college) my mower blade's newly sharpened razor sharp edge.
As a guy who ran a maintenance division for years, i can say with certainty the worst thing that will happen from a razor sharp blade is that it will reach the point of butter knife sharp. There is no sensible argument against it other than liability in a litigation nation.
How do I sharpen my riding lawn mower blades?
same way, you just have to take the deck off or purchase a lift such as MowJack
Have you ever thought of balancing your mower blades, to prevent vibration. Kiwi
