Is this normal wear and tear on the mower blade?

I went to go and sharpen my mower blade, and it looks pretty beat up. I only use it to cut my grass so am surprised to see so many dings and dents. Is this typical? Should I just buy a new blade or should I bother trying to sharpen this thing?

Im a big fan of my mower/blower but was a bit surprised to see how bad the blade looks already. Thanks!

How often do you sharpen it? looks like it has been awhile.

This would have been the first time sharpening it.

after how many uses? (time spent cutting would be a better variable to measure if you can figure about how long)

Shrug, maybe 10 hours? It has not been performing as well so I read about sharpening and figured I would give it a try, have not really looked at the blade until today. 

How often should I be sharpening?

I like to sharpen mine every 3-5 hours which roughly equates to once a month. Its much quicker to do quick 'touch up' sharpening sessions vs letting it go too long and getting dinged like yours is. Another tip would be to make sure your lawn is perfectly clear of any debris that can get sucked up into the blade.

My blade has a couple of dings like that, but in my case I know I hit a chunk of concrete with it. Outside of that one ding, the rest of the blade looks fine. Methinks you're hitting debris of some sort and not realizing it.

I have definitely gone over some sticks, did not think it would be a problem. Definitely no concrete. I guess I will have to be more careful!

Do we think this blade is salvageable or should I just start fresh?

Paul, if you've hit sicks and/or other small debris I would think that's pretty normal wear.  I get the odd ding in my blade and I live in a townhouse subdivision with few trees or other obstacles.  In fact, the only thing I can specifically remember hitting is mulch (bark chunks) that my wife dresses the gardens with.

I would think that blade is serviceable.  Since the mower blade is so quick to change, but sharpening can take a good 15 minutes or so, I went and bought a second blade.  I figure I'll have this mower for long enough that I'll eventually wear at least one blade out anyway, so I'll keep the second one sharpened at my convenience and switch them out once a month or so before a cut.

I sharpen at most every other time I cut. I have a second blade to swap out so I don't have to sharpen when I'm ready to mow. I think the ego blade is a bit softer than others I've used, and really wish they offered a premium version.

The photo of the blade makes me think the blade is perfectly fine once sharpened.

I agree that the blade appears to be softer that previous blades that I've used on gas mowers. I noticed this the first time that I cut with the 21" SP mower. I sharpen the blade every 2-3 cuttings. The softness and the lack of "suction" are major negative points for an otherwise great product.

Hey David HD, I realize your question was directed to Dave, but I'll offer my unsolicited opinion as well. :-)

The hedge trimmer was my first Ego tool after the lawnmower, and I was very impressed with how well it handled some very overgrown bushes with thick branches. I probably SHOULD have done some maintenance on it by now—but I haven't—and 2.5 years later, it still works perfectly for my needs. Granted I use it around every 2-3 weeks so I'm not dealing with huge overgrowth, and it might perform better on a heavy duty job if the blades were sharpened. But honestly I haven't taken the time to figure out how to do that yet because I simply haven't needed to.

Thanks David.  I have been wanting to buy this hedge trimmer, because I am tired of dragging my power cord around the house - when using my Black & Decker electric hedge trimmer.  I already cut my 25' power cord and had to get a new power cord from HD.  What size battery comes with your EGO hedge trimmer?  I have an extra 2.0 Ah battery when I bought my 15" trimmer, and was planning on using it.

My hedge trimmer dates back to when there were just 2ah batteries in all the handheld tool kits or a 4ah battery with the mower. I haven't ever used an entire 2.0ah battery in the hedge trimmer, as it seems to use the least power of all the Ego tools.

That is good to hear, as most of my trimming will be in Spring & late Fall.  The wife's Hibiscus flowers are fast growing flowers, so I have to trim these flowers more often - otherwise, they tower over the roof : (

Just verified with HD website on the EGO hedge trimmer, and they are selling it with a 2.0 Ah battery.  So I guess this battery is more than sufficient for what we need.

David, there was so much wear on the blades within the first 30 minutes of usage that I photographed them and uploaded them to this forum.  If you find my post w/ pics you'll see what I mean.  Judge for yourself.  They still cut decently but man oh man is there a lot of material gone from the edges!

I found the link to my photos:  https://community.egopowerplus.com/ego/topics/bought-hedge-trimmer-today-and-discovered-more-than-15...

there are several pictures in the thread.  As noted by me, my old trimmer NEVER had to have it's blade sharpened, in over 10 years of use.

Thanks Dave.  A picture is worth a "thousand" words, so clearly, the "soft blade" in this hedge trimmer is not withstanding.  I have to rethink the EGO hedge trimmer for now, and will stay with my current B&D electric trimmer.  I need a tool that will last a long time, like my last Sears Craftsman 22" SP lawn mower.  I used that mower every year for 18 years, and did not do maintenance on it like I should - yet it worked fine every time.  I will wait to see the next generation of EGO hedge trimmer, whenever that will be ...

FWIW, here are pics of my hedge trimmer that I have been using for 2.5 years now since I got it in February 2014 with no cleaning, sharpening, or maintenance.





Not sure how this compares to other trimmers, but it still works great—and cuts infinitely cleaner than my obscenely expensive manual Fiskars Quantum hedge shears without either having been sharpened.

first of all the trimmer I purchased may have softer steel than the one you got two and a half years ago and secondly you did not take close-up pictures of the blade so it's hard to see what condition it's really in

Hey!  Calm down.   No one is asking you to retake photos!!  You seem to have a heck of a chip on your shoulder.  All I said is that it's hard to see the condition of the blade.   Jeez, dude!  No need for your snide comments.

As the EGO products are made in China, or so I was told by CSR, it appears that they are using a cheap, substandard, untempered steel for blades on at least the mowers and trimmers. Guess that I'm done buying EGO until they address these blade problems. For my 21" SP mower, guess that I'll have to buy a new blade every year or so. Mower is great, blade sucks. Glad that I held onto my gas mower for serious cutting and lawn cleanup.

Too bad. Good product that they elected to cut corners on a cheap-o part that reflects poorly on the brand.

I'm in the same boat as David Cline. My hedge trimmer works great, and although I haven't used mine as much as some people have the first use I put it to was rather abusive; cutting back a half dead tree. I force fed it branches right up to the maximum thickness, both healthy branches and dead woody ones, over and over, and it sawed through them just fine.

The second use was loaning it to a buddy who needed to trim back an acre of cedar scrub that was encroaching on the trails on his back lot. When I asked how it worked he told me he showed it no mercy for about two hours, and that he was so impressed he'd already ordered his own (he already had the Ego mower).

Since then I've only used it for light duty trimming around our small lot with only one medium sized tree and about 30 ft of "hedge-like" bushes to maintain. It still cuts great. I haven't inspected the blades for damage, but I guess that's because it still cuts well and I haven't felt the need.

Oh, forgot to mention I bought it used on EBay, so not sure what it went through before I got it, but it appeared to be in good condition and worked fine.

Harry, if you need a hedge trimmer why don't you try the Ego out for yourself and if it doesn't perform to your liking just return it?

I doubt the steel is untempered (try test drilling it) but probably not to a level needed to keep an edge longer. Maybe a QA issue.

My blade after a few months of use is still pristine. I don't mow rocks, concrete slaps or large sticks. My wife picks up all the sticks before I can mow them. :) The blade photo above looks to have had its fair share of non grass items. LOL

LOL!  Nope, it's expensive enough giving them water.  My bill for the last 2 months was the highest ever--$300.  I don't have a huge yard, either.  I just live in a stupid-expensive area.

I sharpen my blade ever 2 hours or less. So 3x per mowing session. I go through about 3 blades per year. And that isn't too bad for wear. Keep your blade sharp. Those ridges would not be there if ya had sharpened the blade more often. I got some wear on some blades, i toss them, but ill take a pic of my next dead blade.

If i had to sharpen a mower blade after every 2 hours of use, I'd switch mowers.  or blades.  that's WAY too much maintenance for me and I'm all about preventative maintenance.  I don't like tools that need to be babied.  My honda was lucky if I sharpened the blade more than once a year, and it cut just fine.  the Ego blade is rather soft, IMO, given how the edge became dull over the last few months.  But it hasn't dulled so much that I would feel the need to sharpen it every 2 hours.   Having said that, I don't have debris in my yards other than an occasional twig  or leaf from our bushes.

I have been doing this for 3 years now. Pretty sure i know how to get the most efficiency out of my battery charges. Also, know that a dull blade on any mower tears your grass, it doesnt cut it. So tear your debris free lawn. Ill cut mine with a sharp blade. It takes me 2 minutes to reset the blade edge, saves me over an hour mowing each time.

I just bought that exact same one last week and sharpened both of my 21" blades with it. It is much more substantial than my old one (which someone here had recommended a year or two ago), and did a great job sharpening my blades to a near-razor sharpness. I just finished them off with a few passes of the top and bottom on a fine whetstone.

I dunno Ken, my vision of low tech blade sharpening starts with beer and ends with bandaids, hopefully resulting in a mower that can turn one long blade of grass into two shorter ones without tearing it out at the root first.

Anyone with a dedicated mower blade sharpening device is pretty much George Jetson in my book!

Hi, Dave. One of the best things about the EGO online community is that members maintain a positive, respectful and helpful attitude, even when they disagree with each other. People like Jacob and Blue Angel hang out here to help others. Disagree and question, but please know that this is not a place where insults will be appreciated. We look forward to your continued participation.

I use my angle grinder with a 220 grit flapper wheel. Hold in hand and graze the surface. Then clean the bottom surface. It takes me 1 minute

I just sharpened my 21" SP's blade after only 3 months of use.  I'm guessing I had about 15-20 hours of runtime on it.  I wish I had taken a before shot, but forgot.  It wasn't in terrible shape, just slightly dull with some notches at the ends - likely from the water main shut off I accidentally hit one day..  :D  

I used the Argo sharpener with a cheap Ryobi drill - worked great.  You don't need a vice; I just held the blade down, overhanging my porch, with one hand and sharpened with the other.  Simples.

@Wrog - I was definitely able to mulch much better and cut more length off of the grass blades than I was able to prior to sharpening.  I guess my mower blade was duller than I thought!

Wrog, I sharpened my blade after every two cuts and it does a very nice job with my grass. The EGO blade is made of softer material so sharpening it does not take long. Secondly, the mower is so easy to stand upright so taking the blade off is very easy to do. Your grass will appreciate a clean cut ... : )

That does a nice job for such a inexpensive tool. How does it handle the curve of the blade would be my next question.

@Exrace - handles the curve just fine, because you are the one controlling the grind. Works brilliant!

I just purchased the 21" mower so no actual experience to report. Id say that even yards we would consider very clean might still have some rocks or pebbles that may make small indentations in the blade. I've noticed the blade does seem thinner and softer than previous mowers I've owned. In my view this is a good thing. Should I actually hit something the blade is more likely to bent which might absorb some of the impact and not damage the motor.

Paul, people have reported mower failures of the electronics, following an impact with a heavy object.  The weight of the blade is not a factor in this issue.  Search the forum to see what I'm talking about, if you like.

Since EGO has 'German connections' - it would be great for the company to offer Premium Wusthof or Henkels steel blades.   German steel - not Chinese steel.   

If not German steel - then US Pittsburgh tempered steel.

I'd also like to see EGO offer an Anniversary or Jubilee model mower with a brushed stainless steel deck.   

EGO mowers really are a boutique item for yard tool cognoscenti.   So - they should offer upgrades for discriminating buyers.  :-)
