greenworks 25112 lawn mower
Used twice nice but louder then I expected
had to slow down when entering tall weeds
July 19, 2017
works great!
We are going into a dry time now so I am cutting the grass higher than usual without the bag, leaving the cuttings mulched in the lawn. The lawn mower does a great job, cuts cleanly and is extremely easy to maneuver. I have three Greenworks implements and they all work well and their customer service has been super.

The deck does NOT raise high enough 8>{
I just purchased the 21 inch 13 amp corded electric push mower. (25112)
My major disappointment is the deck height & the need for more power.

I would like to see LARGER front & rear wheels, or, whatever it takes
to RAISE the deck height another INCH.

I tested it on a very small path of grass that I had cut only 4 days ago & I had to slow down, at times, because the motor was slowing down, even with the deck set at MAXIMUM height.

I was using the mulching plug.
Perhaps using the side discharge or rear bag might? lighten the load on the motor.

I don't like my grass cut short, especially in the hot summer weather.
I live in a semi-arid region that does not get sufficient rain, during the summer.

I certainly hope that Greenworks looks at these reviews, or at the very least they get passed along.

Everything I wanted in a mower and more
I have a large yard. People said I needed a riding mower. I ordered the greenworks mower because it fit my budget and my needs. I thought I would mow small portions on different days. I cut lawn for first time with my new greenworks and it was so easy to use, I found I finished the whole yard in one session. I am a 69 year old female and this mower is perfect for me. Neighbors so impressed with the even cut of my yard, they asked for the yard service I use!

Overall, the mower is very good
Having only used it for a few weeks, so far I think it is a pretty good mower. I have only ever used electric mowers so have bought and gone through several over the years. My previous electric mower just suddenly died this spring after about 10 years. I shopped around and focused in on this one as it was more powerful then my previous mower (13 Amp vs. 12) and a 21" cut vs. 19". And by contrast with my previous mower, which had a moulded plastic deck and housing which was thick, the metal base this mower actually has a smaller footprint then my previous mower, allowing cutting closer to trees and other things. So so far the mower has worked well.

On the negative side, I think the cord management systems is very weak. It is essentially just the plug hanging off the mower. I know they suggest clipping the cord in that rubber thing, but I found that to be almost useless. So I have just stopped using that piece altogether and manage the cord the way I always have over 35+ years. (usually over my shoulder) Being an experienced electric mower user I've gotten fairly good at dealing with the cord, but other mowers have got better systems then this model. Another issues is that because of the way the deck is designed, grass clippings and dirt gets into hard to clean out places. That was the only advantage of my previous mowers plastic deck in that it had less cavities and places for grass clippings to build up.

Another issue is the adjustable grass height. I started out with it right in the middle of the ranges of positions. I found that to be too low and raised it up. I'm now at the highest possible setting and while it is OK, there are situations when I would have liked it to go even higher (Like when mowing in the fall over lots of leaves) So I would recommend that the mower height adjustment be modified to allow for higher cut height option.

Great electric lawn mower
Great buy, should have changed from gas mower to electric a long time ago as I have a small lawn. No more winterizing mower ritual every year and no more running out of gas nor having to pull start the mower. The extension cord is a matter of starting on one side of the lawn and it will not get in the way.

Greenworks Electric Mower
Do not like the gap were grass bag rests on mower body. Cuttings are discharged through this opening and in to the mower motor area.
Handle does not easily fold for transport in the trunk of a car.
In using the lower settings, the blade cut the rubber guard when backing up.
Mower is light weight and the large back wheels make pushing easier.

Overall I did like the mower and would probably buy it again if I find it is a durable machine, which my other electric mowers have not been.

great service from CPO
I love this mower; only reason not 5 stars is that 1st one failed on the 4th use. When I tried to get warranty service, the 2 closest places were both quoting 3-4 week waits. Greenworks said if I can't wait, return to seller for replacement. CPO Outlets made the exchange quick and painless.

Great mower!
the last mower I got, a Grass Hog, I had to put it almost completely together myself...the wheels, the blade, the handle...this mower...I literally just opened the box, took it out, straightened the handle, tightened it (by hand no tools needed), and started mowing!!! Wow!! It cuts great, I ALWAYS mulch my grass, I do not collect it, and it works great! Tip for other "natural" lawn owners out there, if you mulch your lawn with it's own clippings, not only are you feeding it, but you are helping it to be more drought resistant!! It has worked for me for years, and my lawn is the thickest, healthiest looking lawn in the neighborhood!! Plus, I never need to fertilize...the clippings do that for me! It's a great mower...I hope it lasts a long time!

WOW...I'm impressed.
I ordered this on Wednesday, it said free shipping 3-5 days...I JUST got it and it's FRIDAY! Wow...and all I had to do, literally, is take it out of the box, straighten and tighten the handle, and I started to mow my lawn!! My last mower was a Grasshog, and I had to put the wheels on, the blade, the handle, everything...this one, no assembly!! It cuts great, I'm happy with it. My GrassHog lasted about 10 years before it died...we will see how this one wears. So far, I'm REALLY happy with it!

I'm not sure if this is cordless when you advertise 120V., and 24V. Does this operate on both or either 24V. and or 120V.. Is the 120V. used only to charge the 24V. battery? Or if the battery is low, can the machine be operated on 120VAC only?
John on Jun 12, 2013
BEST ANSWER: This is NOT a 'cordless' mower, it only works with ~120V current using an extension cord. This mower does not contain a battery. See short cord and female plug at the end in the pictures, this is where you connect your extension cord to in the mower.

Do I need a special electrical cord and how much would it cost
Paul on Sep 21, 2015
BEST ANSWER: In order to prevent electric shock, use this mower only with a CSA/CUL listed extension cord
that is approved for outdoor use, such as Type SW–A, SOW–A, STW–A, STOW–A, SJW–A,

Extension Cord: Verify that the extension cord is in good condition, is heavy enough to carry
the current that your mower will draw, and is polarized (one blade of the plug is wider than the
other). A 50' (15 m) extension cord should be of 16 AWG, a 100' (30 m) extension cord should
be 14 AWG, and a 150' (45 m) extension cord should be 12 AWG. Undersized cords cause a
drop in the line voltage, which leads to a loss of power and overheating
Have had mower for for two years now, mower started to slow down then stopped within five minutes. Cord, outlet and undercarriage have all been checked. Any advice before returning to store?
Walt on Jun 22, 2015
BEST ANSWER: CPO is an internet retailer, if you purchased the mower from another retailer you will need to contact them for assistance. Or, you can reach Greenworks directly at 888-909-6757
