Mower missing patches of grass

I just bought the 21 inch LM2102SP.  I tried mowing my grass this morning and it seems the mower is leaving patches of grass uncut.  I tried going both directions and I overlap the last pass by 1/3-1/2 the mower.  The cut height is on a level 2.  

Has anyone had this problem or have any suggestions?  

Thanks

Not sure how fast you are walking when mowing, but you might try mowing at a slower walking pace. I have the 21" push model and I walk at a pretty leisurely pace and I might get a missed blade or 2 during the entire mow. Usually the next pass back I just make sure to get that one rogue blade.
Other things to consider. The underside of the mower is kept clean. That helps too. Also, as the bag fills can be another contributor. Make sure the grass is dry when you mow.

Hi Jill. You might want to make sure your blade is aligned correctly. I had a new tractor delivered with mulching blades installed incorrectly and my cut was terrible. After the blades were correctly installed everything worked perfectly. Worth a shot. Can you post some pictures. Steve

Yes, purchased our mower (same model) last June and we have had the same issue only ours also leaves a nice fine row of grass clippings  as well the lines of uncut grass.  I refer to this mower as the "triple your labor mower".  It literally takes 3 passes (the original pass, the pass to go back and catch the row of uncut grass (the mohawk) and the pass to pick up the row of grass clippings).  Last summer when I was reading reviews I found a large number of the same complaints.  I finally got through to EGO Customer Service yesterday (855-346-5656).  Although the customer rep I spoke to tried to convince me this was not a design flaw and I could purchase the Hi Lift blade and this should help, I was persistent enough to convince her that it is an issue and I shouldn't have to pay for the  solution.  EGO is sending me out the blade at no cost to me (as they should).  I can hardly wait to et it and see if it fixes the design flaw.  I surely hope so as my husband and I truly love the concept of this mower and how quiet it is and easy to start.

I have the same issue with my 20" mower. I bought the high lift blade for the 21" and cut it down to fit the 20". It helped a little but the issue you mention is still there.

I recently bought the 21" self propelled mower and experienced the same results, leaving quite a bit of patches of grass here and there. I now overlap more than I used to and it helps, but I have a fairly big lot and it increases the time needed to complete the job as I have to make more passes. I left a Toro 22" mower for the EGO and it's almost if I now have a 18" mower to work with...

Thanks for all the replys. I did try slowing down a bit and it helped a little but there were still some spots that were missed. I ended up returning the mower. I love the idea of electric and I really wanted it to work but I have a wedding in my yard in a week and I need something that looks good right now. Maybe down the road I'll be able to try electric again.

This is a reoccurring issue with a number of customers, but not all.  We have all tried the normal remedies: slower, more overlap, alternate direction, raise/lower cutting height, etc.  To no real solution.  It may be partially due to the type of grass.  In my case, its St Augustine.  Not sure about others.  I never seen a corrective recommendation or response from eGO.  Usually after a number of complaints the thread has been closed.

Two is really low, unless your grass is only 3 inches tall to begin with, at which point the question is why are you mowing so short? that can be bad for the crowns and leads to scorching in warm weather. if your grass is long enough to mow, then having the mower deck set so low on the first pass will just push the grass over so you are slicing the sides of the blades on top, and everything folded underneath doesn't get cut, so it just pops up again. You want a height that allows the grass to be mostly standing up to get a nice even cut. We find 3 is the sweet spot for our northern tier blue grass/fescue mix lawn. If it gets too long we will do a pass on 4 and then go back on 3. We just did this on 3 last night. The wheel marks fade in a day or so. (forgive the brown patches in the foreground, we had a really harsh winter this year and the area near the drive really suffered. )

Re: lines of clippings on the surface:

If I mow frequently enough, the blade is sharp and balanced (very important!) and the grass is dry, I get a lovely cut with my LM2101 Ego mower and no pile of clippings left on the surface.   

If I wait to mow until the grass is long or if it's still damp, I get a bit of a line of clippings sitting on top of the edge of the cut.   Usually, I just overlap the clippings on the next pass and that works fine.

Re: Cutting height:

The height of the cut depends on the type of grass and time of the cutting season.  

Most grass doesn't like to be cut drastically anyway, so if you've been out of town, and the grass has grown a lot, it might be best to mow it twice - start high and then move the blade down for the second mowing.

The centipede in most of my yard doesn't like to be cut low in the hot weather, and scalping will damage it and recovery is slow and may require sprigging or plugs and top soil applications.

At the beginning of the year I can cut low on 2 and that gets the weeds, but later on, as the turf regrows from the winter, I have to cut it on 3.  

The St. Augustine, a wide bladed grass on the shady side of the house, needs to be cut on 3 or 4.

In my case it’s not clippings, but uncut grass. Blade is sharp, grass is dry and lonely curing at 4 or 5 taking off about one inch.

Sure, its known problem approx. 1/3 from the left persistently leaves line of uncut grass. Get 20" universal blade from the store with 3 holes mounting pattern and forget about sharpening or any other problems. That supposedly 21" deck barely measures only 20 and 5/8 so ...

I have yet to find a blade other than Ego’s that fits these mowers properly.

Same issue here I have just mowed the yard twice each time for 2 seasons now.  I keep reading a lot of people having the same issue I just do not think the mower has enough suction to cut some types of grass.  Mine is a mix of all kinds of different grass and its a big yard mowing it 2.5 times to make it look nice sucks.  I spent time sharpening blade, walking slower, keeping the deck squeaky clean; then i am just more annoyed when I look back and see misses when im overlapping by half on each pass.  Very disappointing to blow that kind of money on a mower and the only thing that has kept me going is I can listen to music easily bc it is so quiet.  Real disappointing and I don't think there will ever be an answer.  I Just opened a ticket with Ego I don't expect it to help much.

Have you tried the high lift blade.

I was going to try it but I have read it has mixed results and I thought I read somewhere it is not meant for mulching.  its worth a shot if anyone has had success with it.  I have never had a mower that won't even blow the grass off the sidewalk - I am willing to give the blade a shot before I buy a gas mower.

It is designed for bagging but some users on this forum say it works great for them when they mulch and they won’t mow without it.

it is worth a shot. I will give it a go.
