Great products
I bought my mower about 2 years ago and it has been great. I especially like the cutting height adjustment. I couldn't ask for a better mower.

Great corded mower.
I purchased this mower to replace another electric corded mower. I had problems with the previous mower burning out the power switches. I bought this mower and have been using it for the past two years without a single problem. This mower is much better than any of the previous mowers I've owned.

Great mower!!!
I bought this mower 5 years ago. It hasn’t changed at all. It has been a great mower with no problems. It bags great and can handle even thick grass very well. All i have ever done to it is clean the underside with a putty knife after each cut and sharpen the blade once a year.

Does it's job with ease
Have had for about 60 days. Mows grass of any height. Mulches cuttings, if desired, or bags them with ease. Easy to maneuver and height settings are solid and easy to set. Recommend to anyone!

Best Mower I ever purchased
This mower is designed and built most excellently. It has plenty of power, and all it's features (collapse for storage, height adjustment, bag attach/remove, back/side/mulch setting and performance. Have had it for nearly four years with no degradation of parts or performance.. Kudos to the designer and the manufacturer.

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.

Easy To Use
Lack of Power
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!

I was using my( 21 in 13 Amp mower 25112 ) mower and mowed as far as my power cord could go. So I went and rerouted the cord and went back to the mower plugged in the same power cord. Started to mow again and 2 minutes later the it slowly lost power. It will not start now. We troubleshot the push button switch and checked cord(c h anged cords) of course but still it will not even try to start. Any ideas folks?

A shopper on Jul 16, 2017
BEST ANSWER: No, this is not self propelled.
I lost my manual. How do I put this mower together?
Maggy A on May 25, 2017
BEST ANSWER: it is mostly done for you. The upper handle merely has to be raised up, take the bolts out to connect both parts of the handle frame and tighten. You'll be happy with the results...the mower is quieter than the gas ones and so light you can cut with one hand. Always be conscientious to keep the cord clear though, they cut pretty easily
the grass collecting bag is frayed, where can I buy another one
Peter on Jul 5, 2016
BEST ANSWER: Unfortunately, Cpo does not have a replacement collection bag. Please contact Greenworks direct for more options. 888-909-6757

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
