New EGO owner deciding to give electric a go

I have 10,000 SF of actual grass to cut out of a 1/3 acre lot.  About two years ago, I replaced my 2 cycle Lawn Boy of 18 years, with a used 30" Toro Timemaster.  The extra width has been very nice, but the mower is fairly heavy and I have a couple of repairs over the past two years which has lead me to consider electric.  In addition to a possible power change, I hope I do not regret going from 30" to 20" cut!

Home Depot recently had a sale:
EGO 20" Brushless with 7.5 Ah LM2022SP for $674
EGO Power+ String Trimmer + Edger w/5.0 Ah for $289

I should receive the mower this week and I look forward to trying it out this fall, after the lawn thickens back up after a hot summer we have had in St. Louis.  I have a section of Zoysia which I planted two years ago, with the majority of lawn Fescue / Blue Grass combination.  

I went with the LM2022SP mostly due to the side discharge.  I used the side discharge on my Timemaster at times when I would go a little long between cuts and my grass height got away from me due to lengthy rains etc.  I am sure I will have questions in the near future but I look forward to going electric.

Calculate how much time it will take you...:)
As an old man...I'd be riding a mower for 10,000 square feet...:)

We mow about 1.5 acres, both lawns and trails, and we love our ego! Don't listen to Paul, it is nice meditative work, gets you outside and enjoying the weather. Our back yard is about your size and we can do it on one charge in about 1/2 an hour if we keep up with the growth. Long grass took about 45 mins the other night. I will confess we did buy 2 so we can double team the whole property. I am a smaller, older woman, and what I love is with the SP I can now help with the mowing. We have hills and I was never comfortable with the noisy smelly rider or our push mower, and all the maintance was just a heck of a hassle. btw, we just mulch and have never used the side discharge or bagger. But we are out in the country where the day or so for the mulch to work down is not a big deal. We have thick heavy blue grass/fescue here in Mn, and the key to a good cut, if the grass got too long, is to just raise the height, slow down, and let the mower do its work! Also, in that situation, making partial passes really helps. You can zip over it again to shorten things up. Full disclosure, we aren't lawn snobs so we think the lawn looks fine after a mow. Any stripes from the wheels or odd spots aren't noticeable after a day. Some folks complain their lawns don't look like a putting green immediately. (often it was too long to start with) So if you are used to a perfect manicured look, cutting more frequently or taking two passes on different heights in different directions will ensure happy results. It's so pleasant to use, you won't mind.

LOL.  Yes, I have done that calculation on mow times and it is obviously a little longer, but not more than 15 minutes or so.  I actually had a JD 48" front mower deck model for about year, but it was overkill and I didn't like the mammoth machine taking up garage space nor messing around with small repairs all of time.   I am 53 but not really ready to go the riding route just yet.  

Prairiedog, thanks for the feedback, it sounds like you cut a lot of grass with push mowers.  I am hoping however that I do not have to mow twice for a qualify cut or mow more often, as that would probably put me over the top.  I guess I would state that my expectations for the $$ is that the mower does the same quality of work and that it can handle the size and type of lawn in a similar manner.

grin. Didn't mean to make you uncertain. I was only throwing out without knowing your expectations, that with any mower, putting green smooth lawns take more tending, the power source is really irrelevant. The folks that complain the ego is lacking often end up admitting they didn't mow for 3 weeks during monsoons, their grass was 12 inches long, and they tried to cut on 1 at high speed the first pass and they whine it doesn't look like Augusta when they were done. For us, if the lawn looks respectable, neat, and tidy, we do have other more pressing things to obsess over than precision maintenance of that much grass, grin.

I am curious why you didn't purchase the 21" dual battery brushless lawn mower for about the same price.

I think because Ken wants the more traditional side discharge that the steel deck mower offers.

Yep, the side discharge was the main issue, just in case it doesn't mulch well and I also did not like the sound of have 4” nose before getting to the cut area. I actually wanted the plastic deck vs metal but those two items were on my mind, plus this one came up on sale :)

Like I always say, "different strokes for different folks.  When Home Depot had their sale on, both of those lawn mowers were on sale for around $670.  Just to let you know that my dual battery lawn mower does a good job mulching and it also has a side discharge attachment.  Since I am the only one on this site that owns one, you wouldn't know that, unless you saw the youtube video Workshopaddict.com.  You also can't go wrong with the lawn mower you bought, especially with the steel deck.  Happy mowing!!!

William, how do you like that rear discharge to a side discharge chute setup? I read a lot of clogging is happening in that setup. I hope EGO will be able to change the plastic decked mowers to a more traditional side discharge arrangement like on the steel deck mowers.

Because the dual battery lawn mower has more power and what is more important, more torque, the side chute attachment works pretty well.  It did not work that well on my single battery self-propelled lawn mower.  I rather mulch, because it turns into nitrogen and feeds my lawn.  It is very thick Kentucky blue grass and I cut it once a week at 31/2 inches.  The longer the roots the healthier the lawn, plus weeds can't get enough water and room to grow.  I don't know why they don't put the discharge arrangement on the plastic deck like the steel deck.  They could always make a dual battery steel deck mower, which would be great, except for the price.

Just so I understand, is the dual battery mower running on both battles (Serial) at one time, or using one battery and then switching to the other?  I would assume they are running in Parallel, thus doubling the capacity of amp hours of the battery while maintaining the voltage?

If it is running on both at the same time, how is it not overheating the motor?  I was under the impression that the motors were all 2000W motors on the mowers at 56V?.  

I am by no means an EE so any clarity would help

Ego power management system prevents overheating.  Power is being drawn from both batteries.  The system balances the draw form the batteries.  Basically utilized as one large power source made up of multiple cells.  Same system as the snow blower which has more info available about how it works.

Featuring Peak PowerTM technology, it combines any two ARC LithiumTM batteries for the power to clear heavy, wet snow. Built with a high-efficiency brushless motor and a 21-inch wide intake, this snow blower can handle what the city snow plow leaves behind.

I also have 10,000 sq ft to mow and it took me around 4-5 hours. Charged battery 2 times and then had to recharge a battery for my blower to blow the so called mulched grass off the lawn. We've had rain and I was only 2 days off schedule because of rain. Grass was thick and taller than usual. Many factors affect battery time. I have thick bermuda and have to cut at the 4th level when I want to cut at the third. I also have so called mohawks (missed cuts) on the slopes. Even ground is alright. What I sincerely suggest is for you to try the daylights out of your new mower comparing it to previous cuts by gas powered mower within the 90 day return policy of HD. After that the Ego is yours no matter what.

Huh. We have hills, it was 95 the last time we mowed, and as I mentioned we do 1.5.acres, including rough paths.

I hope my experience is closer to Prairiedog vs Jack375.  If it cannot cut a thick fall lawn on one charge with the 7.5 Ah battery, it will be going back!

I hope so too, and with your 5 amp as a back up, it shouldn't be a problem. Just make sure both batts are charged when you start. They swap out in an instant, way faster and easier than filling a gas tank. Put the depleted battery back on the charger while you are finishing up, and by the time you are done, it should be charged or nearly done to do the edging. I guess everyone has their own tolerance, but even before we had the spares on hand, and we had to stop and recharge to get it all done, it really wasn't a big deal. It's not like you are tied to watching the charger after all. We'd just do other chores, or relax and have a lemonade on the porch.

Yep.  I think my only issue would be wishing that I would of purchased the model with (2) 5Ah batteries instead.  I went with the metal deck because of it's side discharge and front of deck only have a 4" area outside of deck vs 7" on the plastic model, but I may have to rethink that if I cannot get it all cut on one charge.  It probably would be nice as well to also have an extra battery as I add other tools  :).

Most find the best deal is buying whole kits so you get another batt and charger., especially with the specials and sales. I have yet to complain I have too many batteries, lol.
