I just discovered this brand of lawn tools from the internet. So far, this brand has worked out for me. Also, it was on the lower end of cost compared with other recommended brands.
[This review was collected as part of a promotion.] Outstanding !!!!!!!!! I had a 16" 40V push Greenworks mower, now with the new 21" 40V self propelled mower, life is wonderful !!!!!!!!
[This review was collected as part of a promotion.] The mower arrived almost completely assembled. After taking it out of the box, it only took a few minutes to get it running. It is easy to use, lightweight, and does a great job cutting. I definitely recommend.
works great!! Very easy to assemble and easy to use. this brand makes great products that last along time. To me the price is a tad bit high, but the product cuts very well and lasts , so in the long run its well worth it to not have to deal with the problems that other brands have. Thanks
[This review was collected as part of a promotion.] Power is good, nice and quiet, the self propelled start and stop lags some.
The battery loses power very quick. Also, I purchased 4 yr protection plan, but never received the promised email that was supposed to send to me for the details of the policy. I called a couple of times, was told it will be sent to me in 24 hours, but they never sent me the policy details about the 4 yr protection plan I bought.
[This review was collected as part of a promotion.] This machine cuts the grass well and with the dual battery port I had no trouble completing my yard. I found that the kill bar was very sensitive and when I relaxed my grip, I often inadvertently killed the engine. Also, I had trouble when I needed to back up instead of going in circles. Likely the irregular shape of my lawn and somewhat rough terrain contributed to my troubles and I am sure I will get better as I use the machine more. If you have a flat lawn where you can mow in a in a neat pattern, then this machine would be wonderful
I have always had greenworks products and love them. However, this mower didnt live up to my expectations. The battery life is horrible . So far the longest it has lasted was about 15 minutes. i have 1/3 of an acre and it took me almost 3 days to mow it. i would mow for 15 minutes then have to charge the battery for 3 hours. mow another 15 minutes or so and charge for 3 hours. got really annoyed at not being able to finish my yard in one day.
The mower kept cutting off and Ihad to keep restarting. The battery lasted an overall 34 minutes, then it would restart anymore. Soooooo, half of my lawn is left for tomorrow.
I just bought this lawn mower, and when I used it for the first time, it stopped working after a short while. After some time, it could run again, but it keeps starting and stopping intermittently, which makes it very difficult to use. In addition, the battery runs out very quickly.
