What keeps grass, moisture, debris from entering the motor from underside of the mower above the blade? There is open area with exposed copper wire visible.  See this link for reference. http://homedepot.ugc.bazaarvoice.com/1999m/463293/photo.jpg

The design of the deck and the action of the blade push clippings and debris out and away from the blade
spindle. What you are seeing through the small opening for the blade spindle
are the copper windings for the motor. Copper windings are an essential part of
every electric motor. We have extensively tested the EGO mower and can assure
you that the windings and their location will pose no problems. In the event
that any debris is deposited on the insulated windings, the performance of your
mower will not be affected.

 

You also have the assurance of our 5 year warranty. We stand behind our products!

The most important part of the question is what happens if & when the windings get wet. It is bound to happen. Also, will that void the warranty? Would seem like some kind of cover would eliminate any possibility of winding getting wet.

Thanks, liked the reply that didn't get posted
Your mower will be covered by our 5-year warranty unless it is subject to misuse or abuse, such as mowing through standing water or leaving it out in the rain or under a sprinkler. Our design takes the normal moisture from cutting damp grass into account and our testing confirms this.

Hey Jennifer

I agree with Big Jim, as a mater of fact I was going to ask those same concerns of moisture and debris. 
Upon contemplating what mower I am going to get to replace old Dyno lawn mower, the features I am looking for are: electric start,  fold-able at the handle (or easy to take apart via a couple of screws) to allow for compact storage for the off season, self propelled, reasonable price, preferably as much as possible American made and energy efficient. I was big on trying to find a good battery operated one, but after much research on the internet with many reviews and specs, going to "big box stores" and implement dealers, I concluded it was not possible to get all those features.  

A couple of weeks ago, my wife and I went to the Home Depot to check out lawn mowers after deciding that the new Toro smart stow model was the way to go, it had everything I wanted except electric start; it ran on gas instead of battery power. Pluses include: it's American-made( including the engine), it folded up when not in use and was reasonably priced. While talking to the sales person and telling him the features was looking for, he led us to the Ego mower, explained its benefits, noted the price was high compared to the Toro ($349 vs. $499) and that it was 100% made in China (not a total deal killer, because we have a global economy). I was very interested until I turned it over and saw the open windings. I immediately stated “what a terrible design.” I realize that the windings need to get air for cooling, however, a tight mesh screen over it would still provide cooling while minimizing moisture and debris from getting in there; all you would have to do is scrape off the grass/mush clippings after each mowing. Let it be known that small sticks pose a hazard of damaging the windings too, it is very unlikely that the lawn would be totally void of sticks, even after a careful picking-over. I would highly doubt that your 5-year warranty would cover sticks or lawn shavings caking up on the armature that cause damage to it, thus shortening the life of the motor.

Now lets look at the moisture issue in more detail, you stated on another post “Avoid dangerous environments. Don't use lawn mowers in damp or wet locations. Do not use the mower in the rain.” With my dyno mower sometimes I would start mowing with no rain present, the forecast is calling for rain for the next few days or possibly the whole week and my grass needs mowing. I am nearly done and it starts to rain, with a dyno mower I can finish up mowing so long as there no lighting present. Given possible future circumstances as these, I have grave concerns about the open armature port on your mower in both wet and dry conditions.

In summary, the Ego appears to be a great idea if you have an immaculate clean lawn and no moisture present, including dew and if money is not an issue. There are way to many minuses: the open armature issue, very expensive, and yet 100% Chinese made. Quite honestly my wife and I really wanted to buy this mower, by far the biggest issue is the stick and wet issues. If you can clarify that there is no issue with the windings getting wet, or sticks and mush causing damage to the motor when it comes to the warranty, we may be open to reconsideration.
