Mower not cutting well. I bought the self propelled model and it leaves streaks of uncut grass everywhere. I have tried sharpening the blade mulching bagging nothing works. Still have streaks. I really want this mower to work for me. But I am having majors issues. I do plenty of overlap on passes and am cutting my tall fescue grass at 4. About every 5 days.

Is that 4 inches or at notch 4?  I find that above a notch setting of 3 result is a poor cut on fine fescue.  I am waiting for the new blade that will pick up the fine grasses for a better cut.

Are you always cutting in the same direction, for example north and south? Regardless of what kind of mower I've owned I've always changed directions at each subsequent mow. Always seemed to make for a more even mow each time. So, north/south one time and then the next time east/west.

This has been an ongoing well documented problem with this 21" model. The only thing that seems to help is to reduce the amount of the blade of grass being cut off. Since it doesn't mulch well the less you cut the less it will show. There's no better solution. Alternatively, you might want to bag the clippings​ when having to cut more than an inch of the grass blade.
The original 20" mower mulches beautifully. l dont know about the new 20" steel deck version. Need to see some reviews..

Rob, I miss understood your problem...(I thought you were referring to rows of cut grass left on the left side of the mower path) rows of uncut grass is usually caused because the wheels or other means have tamped down the grass before cutting and it isn't springing back up. This happens more if the grass is damp or too long or both. We will have to hold our breath to see if the high lift blade can help resolve this type of issue.

I don't really know how much of each blade of grass I'm cutting off, but I use the #2 setting on my 21" mower and all the grass gets cut very evenly. I don't use the mulching feature so maybe that's part of the problem, but just for straight up mowing, I get nice even mows every time.

If you are going to buy a random blade why not just buy a 20" mulching blade and save yourself the need to cut it down to size ?

I think Terry’s comment about a longer blade that is closer to the inside edge may be worth pursuing so want to try something closer to 21”

But, if he cut 1/4” off each end he is only 1/8” closer to the housing. I think EGO needs to look at the aerodynamics of their blade.

Also, know using non-EGO blades voids your warranty and if you are using tiny spacers that sound like they are not trapped by the motor shaft be careful at speed the blade has high potential energy!

( these unsafe posts are the ones EGO should edit! )

I am having somewhat of a similar problem in that my first cut was last Tuesday around my garden with my new EGO 21" Self Propelled mower. It was set at #4 Height Setting. The Grass was about 2 Feet Wide around the Garden for this test run. Four days later the grass (which was slightly wet) is as high as it was on Tuesday!! Going to take the new blade off to sharpen it & try again.  Also when trying out the Self Propelled Mode the Mower jumps then takes off like a bullet - is this normal?

Thanks for the link, szwoop!

Dave, now that I think of it, that poster's issue was a complete lack of operation. It may not have anything to do with your issue isolated to the SP function.
I am having the same problem. If I go over it twice it cuts beautifully. I did notice that if I do not engage the self propel function I get a much better cut. It looks like the deck raises slightly when self propelled is engaged. My yard is hilly and I need the power.

Try applying some upward pressure on the handle while mowing thus keeping the front end on the ground.

21" SP Mower now working Well:
Well this is quite remarkable - from reading other suggestions on the Forum here -  today I lowered the my EGO 21" SP Mower from setting #4 to setting #3 (2.5") and now all is well!!  The mower cut the partially wet grass in Mulch Mode around the Garden well, and the Self Propelled function no longer Jump Starts when I select it. Only my 2nd time cutting with the 21" SP mower but I can easily live with this. Also cleaning the mower was a breeze, first I wiped the under deck down with a dry cloth to clear the grass cuttings, then I dipped one corner of the cloth in a bit of water in a margarine container squeezed it out and wiped the under deck again to a clean finish, great.  Thanks a lot for the helpful suggestions, guys and girls.

You can add an additional .25" to the cutting height in each setting, the blade is recessed .25".

My ego 21" SP mower is leaving streaks of uncut grass on the higher blade settings.  Using the original blade that came with the mower and a 4.0amp battery.  These are light cuts, cutting the lawn about every 4 to 5 days.  The streaks are inconsistent but seems to be primarily in the more lush areas of the lawn and at the edge of the cutting radius.  From the comments here, it sounds like a lower setting might have better results but in the warm summer days, need to stay at the higher deck height to help the grass maintain moisture.  Mower is one notch off the top deck height.  Any better results at the higher heights with the newer blade?  Would a stronger battery have better torque/results?

When I talked with customer support in grand rapids Michigan she suggested this was normal and going over the affected areas multiple times would help!  The other suggestion was to leave the unit at Home Depot for repair....

Also having strips of uncut grass. Mower was purchased September 2016 so not a great deal of use. It is the 21inch SP 56V model. I have Bermuda grass. Also noting diminished battery life. Down to 30min now. That is not acceptable. I have called customer service and am waiting for a call back.

Anne, the most common cause of diminishing performance is a dull blade. Have you tried sharpening it? Also, what height setting are you using?

I have had the same experience with thicker Kentucky bluegrass. The mower just doesn't mulch well and leaves streaks mainly on the left side. Like the mower, but after a couple of months I am giving up and selling it. Takes too long to double mow areas and I'm tight on battery time. I have sharpened the blade, change mowing directions, etc and no luck. Confusing to me why everyone loves this mower so much for mulching.

Blue Angel - THANK YOU!  I looked at the Home Depot return policy again and we returned to ask again if we could return it.  This time the person checked the code on the receipt and said yes.  So we were able to return it and I bought a different mower that works great for my situation.

For anyone that reads this thread, please do not take my comments to mean I do not like this mower.  I like EGO and the people on this forum.  It is a good product but just didn't work for me. I wish EGO continued success and hope I can look at one of their models in the future.

I previously reviewed this mower on homedepot.com and gave it 4 out of 5 starts.  I stand by that and still recommend people give this mower a hard look.  Only issue I had was thick grass and my new gas mower has no issue with it at all.

Any time, David!  Maybe an Ego string trimmer or blower would suit your needs?  The 15" trimmer is a real sweetheart! :-)

David... what mower did you get after you returned your Ego? I have thick KBG & I am so frustrated with the horrible cut quality of my Ego on cutting height setting # 5. About to give up on Ego.

This is my first year with the 21" SP and now that my Bermuda is in its thick summer mode, I am now having issues with tons of grass collecting along the left side in mulching mode. Typically a second pass takes care of it, but that really adds to my cut time.

This is on setting 2 while cutting twice a week, dry grass. I did notice that my blade was already pretty dull so I did a quick sharpening before my last cut and it seemed to help a bit. Next cut I'm going to make the blade razor sharp to see where that gets me.

I purchased on the HD card so I'm not in a huge hurry to make a decision, but this summer will be my trial period. I want to love and keep this mower, but if I can't get past this grass collecting, I don't know if I will.

Cutting in a counter clockwise pattern allows you overlap the left side portion of the previous pass.  Thus you do not need a full second pass only partial.

I've been adopting this method and it does help as it just keeps moving the clipping line towards the center. That said, while it's a help, I am finding I still need to make some additional passes to really clean things up.

I've also tried letting some of the clumping go and following up with a quick blow from the EGO blower. It's quick and works well, and fairly efficient since I already have the blower out for the hard surfaces.

I'm going to give it a real effort to make this work because I want it to suffice for me.

Brad, is it possible to mow at one notch higher than you're doing now during the high growth rate season?

I don't have Bermuda grass so it may act differently, but with my northern lawn I notice a dramatic reduction in the load on the mower as well as far less clippings collected when cutting at a higher height, same mowing frequency of twice per week (I'm bagging clippings right now).

Might be worth a shot?

  • 2,250 Points 2k badge 2x thumb
It's not recommended to go any higher but I suppose the reality of another 0.5" might not be a big deal. It's worth a shot during this period where I'm trying to make this work for me. I think I'll try my "razor blade" cut next to see what that does for me, then I'll try level 3.

I want to hear more about the HL blade as some reviews state that it helps with this problem. I need some of you all to get your hands on this blade and report back ;)

My razor blade cut wasn't really any better. I had grass all over the cut path, so bad that I needed three passes to completely clear the lawn of clippings. Three!

I've since done a cut with position 3 (from 2) and that didn't leave any clippings....however there wasn't that much growth needing to be mowed. I'll be curious how it goes over the next couple of weeks as 2.5" becomes the new base and things thicken up somewhat at that height. I definitely don't want to go any higher as it's already starting to be higher than I like.

I received the 20 in. brushless model mower two weeks ago and have cut three times so far.  Pretty disappointed with the amount of uncut grass left behind.  Have tried the highest setting and down up to two settings and no discernable difference.  I called EGO customer support and after waiting a while was forced to leave a message.  Never got a call back.  I really want this mower to work out as I like the idea of electric for my smaller yard but quite frustrated.  The mower does not seem to bog at all while cutting so I'm thinking the blade rotational speed is just fast enough.  I have tried walking slower and such and does not help much at all.

Thanks for question.  It's Kentucky Blue and no, but the blade is new and only has about 20 min of cutting on it.

I have blue and fescue and get a pretty good cut. So, that should not be the issue unless your lawn is extremely thick - there have been a few complaints on that front.

Although the blade is new, they don't seem to come very sharp from the factory.  You might want to sharpen the blade and see if things improve.  Others have reported great improvement from doing so.

Also an overlap of the wheel marks seems to help.  If your grass tend to be on the left side, then a counter clockwise cutting pattern with an overlap of the wheel tracks can also be a big help in getting improved results.

21 inch self propelled mower set at #3. Very poor cutting and leaves a ridge on right side following wheel rut. Tried sharpening though mower is new. What I did do was put another blade on from an old mower. Wow my lawn was beautiful. Worked so well BUT cut 7.5amp battery run time to 20 minutes and I don't use self propelled feature. So I imagine designers had to sacrifice a good blade for battery and motor life. Very disappointed.

Mike, I  can't tell you. I don't know. I have owned many lawnmowers and I don't throw anything away. It's mute however because its extra weight and resistance puts to much load on the Battery (motor). As I said I suspect Ego knows about this but cannot provide a blade that works without ruining the motor.

I have tried really, really hard to love this mower (21" SP), and I do love everything about it except for the mulching capability.  Midwest KBG / Fescue mix, always cut at 3.5" this time of year with Honda twin blade mower and no problems with clumping or noticeable clippings.  I've tried a new blade (sharpened to the extreme), and also experimented with a twin blade setup on the EGO, but gave up trying to get a mulch cut similar to my Honda gas mower.  So back to Home Depot it goes - I have the EGO string trimmer and blower, and absolutely love them both, and am contemplating purchasing the snow blower.  Unfortunately I can't go 100% electric as the mower just doesn't perform like I need it to.

I purchased the 21SP mower 2 months ago.. I love except for the streaks it's leaving. My gas mower used to cut so evenly that I do not want to deal with this uneven cutting. Does anyone have experience with a better battery self propelled mower other than this EGO??

A month ago I purchased the electric selfpropelled kobalt mower. It ALWAYS leaves rows of uncut grass. I've tried cutting it on all different settings. It doesn't matter if the grass is 5 inches or 2 inches long, it always misses some. I've tried to sharpen the blade and it doesn't help. The people at Lowe's told me I need to cut tall grass on the lowest setting or else I would miss some. Lowe's told me the battery would last about 45min. I can't use my mower for more than 30min without the fully charged battery beeping at me and dying. AND I even quit using the selfpropelled feature to try to get an extra 5 minutes out of the battery! I love how easy the mower is to start and how light weight it is, but I keep having to resort back to my craftsmen gas powered mower to get the job done. Lowe's won't let me return it now. Huge waste of money and time! Email me if this can be fixed lit.tal.ma1@gmail.com.

I have had this same problem for 2 years. Used different blades, different cutting heights, nothing helps.  I had an unrelated problem, wouldn't start and had to send in for repairs.  After 8 weeks they sent it back and said there was nothing wrong.  Went to pick up at Home Depot and it wouldn't start.  Manager gave me a new machine. Starts fine but it also cuts terrible.  Must be poor deck design and EGO offers no resolution.  I purchased a Greenworks machine to use while the Ego was in for repairs and it cuts great. I have other Ego machines, weedeater and blower, and they work great. Really disappointed they Ego won't admit there is a problem let alone offer a fix.

My Ego 21" self-propelled does not seem to do a very good job with the grass catcher on.  Just does not seem like there is enough power to really throw the cut grass into the catcher?  Solutions or just wasted $850 for an electric mower because I am concerned about the environment?

Pull up the back shoot and there should be a handle, you just pull it out. After that should fill up your bag no problem, and if you want to mulch just put the plug back in.
