Well, I go to use my lawn mower (LM2000) this morning.  As soon as I turn it on, it makes a pop noise and smoke shoots out the top.  
Looks like another warranty claim.   This is my 2nd lawn mower.    
Also, nothing was clogging or blocking the blade.  It was being started on the driveway and it is clean underneath the deck.  The blade spins freely when I try to move it by hand.  

It is kept in a garage and never exposed the elements so I dont get why it has problems.  
I still dont get why that little ring also melts the plastic inside the battery compartment.

Odd, for sure. My 20" mower is 3 years old and hasn't skipped a beat. I have a smaller lawn that only takes about 25 min to cut, but that should be lots of time for the electronics to get up to temperature.

No idea why you are having an issue other than to say melted plastic may have been a warning of the pending pop and smoke.  No part of your mower should be melting at any time.
Depending on your local weather and construction and house orientation, it can get pretty hot in a garage, so that my be something to consider.


I would say a call to customer service is needed.  They are open on Sunday.

The 1st lawn mower had the ring of melted plastic in the battery compartment. It was replaced under warranty. This second mower immediately had the melted ring last year, but it still works.  After a year it just made a pop noise and shot smoke out about a hour ago.  
I have seen another post on here about the melted plastic issue, so I know I am not the only one and it is clear the melted ring is part of their design.  
Regardless, this time the lawnmower popped and failed on startup. It actually shot a stream of smoke out the side like a squirt gun.  

So far I have been on hold for 44min and 37sec.

Sounds like you had a problem as you said you called them before.    
At this point I tell people to stay away from Ego as I dont think they perfected their products yet.    

Those with small yards may not see the issues, but it takes me two full batteries to cut my yard.  One obvious solution I see is they need a cooling fan in the battery compartment as it gets way too hot and melts the plastic.   
I get the batteries are vented, but that does no good if the battery compartment is not vented.

Actually, I was just checking CS response after reading several "long" wait stories.  I have not had any problems with my mower, blower, nor hedge trimmer.  Everything has been working great. 

I think if it took me 2 hours to mow my grass I would be looking for a wider deck and/or riding option.  But, all a matter of user preference.

Good luck with number 3 Ryan

Also dont forget how the grass shoot constantly clogs as it is poorly designed with a curve.  
I had to cut the bottom out of the grass catcher to use that as a grass shoot to prevent clogging.  That worked well, but I should not have had to do that.

That was definitely an after thought.  It is a bagger/mulcher only.

Interesting solution, however.

I say a track record of poor design.  
You will have a hard time trying to tell someone that they did not know a lawnmower needs a grass shoot.  Unless the designer grew up in a sandy desert.       
If they also wanted it to be a dedicated mulching lawn mower then they would have increased the torque of the motor. 

Anywyays, since I got a 2nd grass catcher with the 1st replacement, I cut the bottom out of one to use as a grass shoot.  You only cut a strip out across the bottom right next to the mower so that way it still prevents any debris from flying at you, but all the grass falls right out.

They are going to send me another replacement lawnmower and a return label to mail back the broken one.  
They said I should get a new lawnmower in 7 to 10 business days.     
This seems like the warranty is good for 5 years and I will get 5 new lawnmowers in that time, they need to get their act together.

At least you don't have to wait 4+ weeks for HD to repair your mower...

Screw that. I would be a complaining squeaky wheel with them until they did something faster or paid for a lawn care service.  They must not realize that for people who live in an HOA that waiting that long to cut your grass is not acceptable.

Ryan, as this is a recurring issue for you, it appears your unique yard and ambient conditions are over heating the motor controller located on the top of the motor.  There are two main heat sources in the mower: a) the motor, and b) the battery.  While you cannot do anything to the motor heat source without voiding the warranty, you can do passive cooling for the battery by propping the battery cover open, like so:



I have noticed reduced operating temperature of the battery by using this simple method.  And while dried grass does get in there, since the mower does not have active cooling of the battery like the charge does (e.g. fan to draw air through the battery), then there is no concern that the grass or dirt will be ingested into the battery internals.

IIRC, the melted area is just rear of the battery release, so this method might actually assist in releasing, or not allowing excess heat to build up in the entire upper enclosed air cavity of the mower where the motor and controller are.

Ryan, I read your old post, and did find any more details; can you elaborate on your lawn details, and what area you live in, and the ambient temperatures?  How long do you typically mow for?  What size battery are you using?  Do you bag, mulch or side-discharge?  Something unique to your situation is overloading the mower and causing that ring to melt.

I am in the Houston area, so it is hot.  If this cant handle Houston temps then they should not sell it in Home Depot next to me.  
I have a normal Texas yard for a neighborhood, nothing special. Nothing unique about my yard at all.   It takes like an hour to mow both the front and back.  1st charge cuts my front yard, works my trimmer, blower, and cuts part of the back.  Then the 2nd battery finishes my back yard.      
I originally mulched, but that would cause overheating. Then I used the grass shoot, but the side shoot kept clogging. I then cut out the bottom of the grass catcher so it works as a grass shoot which does not clog.  Id cut with a 4 or 3 setting.    
1st mower I had melted the plastic from the ring but damaged the battery.  The replacement I got melted it on the first mow, but kept working for a year.    With this replacement mower I have only used my custom grass shoot which prevents clogging.  

I think the first batteries were 4.0ah, but the replacements I got a year ago were 5.0ah.

What kind of grass?

Shitty Texas grass. I think it is St. Augustine.   I guess that is the standard in the South.    
It is thick bladed.

The melted plastic is a coil that delivers the power to the motor. Don't know why yours always get so hot without overloading. Seems very odd to me. It's not the heat of the battery compartment. It's inside the mower on top of the motor.
