Only if it can do dishes and I can cuddle to it at night. And actually appear to enjoy it. Lol. That's a lot of power.

I would love a rider as well.  The problem would be run time.  

At one point I seriously looked into converting my old John Deere into an electric mower.  There are a couple of videos on Youtube of guys who have done it, and Amp draws seem to run somewhere around 120 to 150 amps.  That's for cutting (lets assume a 42" deck) and propelling about 500 lbs of man and machine.  

If you do the math, that comes out to around 15 to 20 minutes of run time for a 40ah battery pack.  Not really enough :(

In order to get an hour run time, which I would consider a bare minimum for a riding mower, you're looking at 12  batteries not 4 (maybe even more than that).  That gets expensive quickly, and isn't really practical.  

It wouldn't surprise me at all if Ego was already working on it though. I think there are lots of well-off people who would spend a bunch of money for an electric mower that doesn't make so much darn noise, and requires no maintenance.

It is not current draw alone that you need to look at, it is power, the current multiplied by the voltage, the watts.  I do not know the battery voltage used by the people who you are aware of having done it, but if a riding mower with a 42 inch deck requires about 17,000 watts (note that it does not necessarily, it depends on the rotational velocity of the blades (the revolutions per minute) and the speed that the mower will move at, then from a 50.4 volt battery (nominal voltage of EGO battery pack), it would draw about 340 amps. Note that that would be at full power, and I draw that based on what the Husqvarna Z242F does, and I do not know how many inefficiencies can be removed from that, I do not know how much torque spins those blades, there are a lot of variables to account for with such a device. A 340Ah pack would be needed to run it at full power for an hour given no difference in efficiency between our hypothetical electric zero-turn mower and the Husqvarna Z242F.

A 50+" deck using three Ego mowers stacked together would take about 3000W based on the 1000W rating of the 21" SP mower.

You're correct, wattage is more important.  I believe the video I saw (which I can't seem to find now) was a 48v setup...close enough to the 56V ego packs I just neglected the difference.  

Regardless of how many batteries you'd actually need, I think it's safe to say it's alot.  Of all the electric vehicle conversions I've seen done, the batteries are always the #1 expense.

Aye, but I'd like to go faster than 3.6mph. I want to go at least 10mph, and the power needed to carriage me at that speed I am not sure of, it depends on the friction and the slope of the terrain. It needs to cut grass that quickly as well, and that will require more power per unit deck width.  Also, the Greenworks 80V 21 inch mower is rated 1200W if it is the same as its Victa counterpart in Australia and New Zealand, and I think it mulches better than the EGO. With that said, the power needed also depends on the type of blades used.

Just a guess, but based on my experience with power wheels, user weight is going to be the biggest factor affecting either speed or power draw. My 260 lbs would take a lot more power to move around than someone half my size.

That presents a specification problem... in this day and age of sensitive people you can't even begin to comment on someone's weight. :-)

Lol... "YOUR mileage may vary." :-D

Thanks for the suggestion Lee. We're considering a riding mower for the future but we don't have any plans for it in the immediate future.

That makes me sad :(

No market for it?  Maybe I underestimated the cost.  If a rider is $10,000, there may not be many takers.  I would expect a $3000 mower would sell though.  But I'm not in marketing.

Hey Tim. If our great leader said they are considering it, then it's probably something we will see in the future. Cost of the batteries are the biggest obstacle from what I see. A riding mower is a lot of weight to move around. Like a small car.

Let's see what Greenworks  does. I know that they have been designing a 32 inch zero-turn mower for their 82V Commercial lineup.

32" is awfully small for a riding mower...

it's a start. Even then, to me, it depends on how fast it can go... Small fast ones are a lot of fun.

Given the current Honda/Ego partnership, I do believe we already have a suitable platform... as long as you need REALLY fast:


"109 hp, zero to 60 in under 4 seconds, and it cuts the grass."

The mean mower... yep. that's a winner... There was a guy that modified a Viking T6 lawn mower and made it able to reach speeds over 133mph. "The team said the rebuilt mower features 408 horsepower with a V8 engine and has the wheels of a Formula 3 car. "

Just spend the 4k and get a cub cadet zero turn zero electric mower. Then you can quietly creep on the neighbors while pretending to mow the lawn. Problem Solved.

My style is more like taking one of the above two mowers and mowing their lawns and be done and gone before they have the chance to get mad at the noise. I'd just use a slow motion camera on the mower if I wanted to creep on them.

Have you reconsidered this. Your competition just stepped up the game and is Home Depot exclusive. https://www.ryobitools.com/electric-r...

48V, 75Ah... 3.6 kWh and the word "lithium" is nowhere to be found. Based on the picture that shows four large batteries, methinks this is a good old lead acid battery X 4.

"Convenient overnight charging" also lends itself to lead acid.

Ego, do this, but with the world's largest Arc Lithium battery pack! :-)

Agree.   But hurry up.   I want one....EGO style.  This should be the new push for EGO.

I am sure Elon Musk has some "left over" li-ion batteries he can spare to EGO, for a new 42" riding lawn mower - in a fashionable EGO green !!!!!

You guys are killing me.  I don't feel like spending my home equity on a riding mower.

I am considering the new Ryobi Electric Riding mower but would prefer to purcahse a cordless ridding mower from Ego since I have your mower, blower, trimmer, hedge trimmer and snow blower.  I know you said you considering it but not in immediate future.  If I hold off an wait until next year would I be likely to see the riding mower then?

With that garage full of Ego equipment, you should have a hot line to corporate HQ.

If it is as good of quality ryobi is normally, that thing will will last about a year. Sorry but I seriously dislike ryobi. Junk.

They are lead acid batteries.
