Ego 21″ mower (LM2100SP) 2nd self propel motor failure & repair report

No, this post isn’t an accidental duplicate of this post from last year. Yes, the self propel unit on my 21″ SP Ego lawn mower failed a second time. (This is 9 months after it was replaced under warranty from the first failure, which occurred around month 4 of ownership, so this failed self propel motor lasted twice as long as the first one.)

However,  I’m quite pleased with Ego’s warranty service compared to the last time when I had to take the mower to Home Depot’s service department (who kept it for 5 weeks).

This time when I called Ego’s customer support number, I only had a seven minute hold time before talking to a person, and the customer support representative said that they would send me out a new replacement mower, arriving in 5-10 business days. [I was instructed to remove the serial number sticker and take the defective mower back to home depot “for recycling”.]

I have read many accounts on Ego’s customer web forums of other self propel units failing, so they may have had a bad batch of mowers go out and are now being more pro-active about replacing them. Alternatively, maybe I’m getting a replacement mower shipped out quickly because this is the second issue I’ve had. Regardless, receiving a working replacement in 5-10 days is much better than taking 5 weeks for a repair.   I’m still going to have to push my mower to mow the lawn (and it’s a big lawn, so this is more exercise than I am looking for….) but at least I could use the defective mower as a push mower until the replacement arrived and didn’t have to hire a lawn service while it’s in the shop.

The new mower arrived 11 business days after my phone call (it would have been 10, except UPS had a delivery exception and delayed it over a weekend, which meant I had to push the old mower around one more time.

After using the new mower with its super quiet and silky smooth self propel, I can say that the self propel unit that home depot repaired/replaced had many signs of problems before it finally gave up the ghost. First, it was louder than the mower itself. Second, it didn’t have enough power to fully propel the mower up a slight incline. Third, every time the mower went into overdrive due to thick grass, the self propel would slow down. These issues were either there from the time I got the mower back from Home Depot, or they started and got worse so gradually that I hadn’t taken note of them, but after using the new mower, it became obvious that I should have known my self propel unit was not working the way it was supposed to. On the new mower the self propel has plenty of power to move up a grade at the same speed it moves on flat ground, it makes less noise than the blade mower, and it doesn’t slow down when the blade mower goes into “overdrive” cutting thick grass.


Update: Ego has started to produce updated 21″ SP models that have an updated self propel unit that matches that found in their dual battery (premium) mowers. Look for a picture of a phone on the box (see this video for details: )

2nd Update: My self propel unit failed a 3rd time, but this time Ego replaced the mower with one that has a different looking SP unit, so I’m hopefully I got the improved version!

  3. Have 21″ self propelled mower bought from HD 2 years ago. Last year the self propelled feature failed and I was sent new mower. This year the mower completely died (nothing worked yet battery was full). Brought in to HD per EGO”s direction for warranty repair, that was over 6 weeks ago. Yesterday, HD finally said they looked at mower and it needs a part but doesn’t know when it will arrive or if/when it can be repaired when it does arrive. Called Ego CS and all they did was call HD repair and tell me a manager will contact me when part gets in and of course stated it’s the peak season for repair which I find unacceptable for a mowers to remain broken for almost 2 months. HD is a large national company and EGO’s contract with HD should provide better than a 2 month turnaround REGARDLESS of the time of year. Had I known the unreliable experience I’ve had this past 2 years for this $600 mower coupled with outrageous warranty wait times, I would NEVER have bought this mower period.

    • I agree. My EGO self propelled mower is totally dead. Battery fully charged, back up batteries as well. Nothing works on the mower, not even in self propelled mode without cutting, not even the lights.

  4. I also am on my second Eco, got sent this replacement from warranty, doesn’t self propel , lasted a few months when it stopped completely.. very annoying since I had purchased an extra battery, cost over $400.00.. I appreciated your written documentation dealing with Eco battery operated lawnmowers… hopefully I find a mower that lasts longer than a year

  5. My EGO self propelled mower has stopped functioning. I have had the mower for 2 years. It functions like a manual mower.

    • It sounds like your self propel unit has failed. If you bought it from an authorized retailer and are the original owner, the Ego 5 year warranty will cover you, give them a call to start the warranty repair/replacement procedure.

  6. Got my mom’s ego 1 year old propel motor dead! Cannot find receipt as she now has Alzheimer’s so I call to set up warranty and they tell me without receipt and since the product has been ” transferred ” to new owner they won’t cover. Most bush league company i have ever dealt with. Pitiful arrogant customer service and do not stand behind a poorly designed product. Buyers beware! This is a flawed product!! 300\year to cut your own lawn is no deal. Going back to my reliable honda!!

  7. Only had my self propelled mower for 1 year and maybe used it 8 times. Self propel stopped working. I would not recommend EGO products. It is May and my grass is growing like crazy. It has been in a repair shop, given to me by the Customer Service person because I refused to wait the length of time Home Depot warns about. The repairman has asked for a replacement for me since EGO has never got back to him on parts and timing. So far it has been 1 week.

  9. My self propel mechanism has failed as well. Fairly certain that I have a old version circa 2017. Does anyone know if EGO is replacing old mechanisms with the same part or if they are upgrading old mechanisms to the new mechanisms? Or does the new mechanism only fit on the new version of the mower? (And how do I get one of those instead of a replacement part ?). Thanks!
