Rated 5 out of 5 by from Excellent for small lawns After getting fed up with the high gas mowers and the hassle of using corded mowers, after researching different movers I finally bough this one. So far, it's been fabulous. I had earlier Greenworks blower and I'm able to use the battery for both. The mover is excellent for small Yard. I had a small around 200sqft of Yard and one block of sidewalk. I'm able to finish in one charge. I love it. Easy start, easy moving in small places and no hassle of maintenance. I wish it should come with two batteries. Charging of batteries is reasonable. So far I love it and will recommend this to anyone who is looking for quality products.

Rated 5 out of 5 by from Light and easy to maneuver. I just got it today -11-3-18, and have only used it once so far. I mainly got it for trimming around where my rider won't get and it works great for that. I also have a 40 volt trimmer so the batteries are interchangeable which is a plus. I put the mower battery on the charger and used the trimmer battery for its initial test mow. This first time I didn't just trim but went and mowed most of the yea yard. It handled the mowing and mulching very nice. Then I put it in the garage and went in too warm up. It was only about 38° but I just had to give it a try. I was pleasantly surprised! She's a keeper.

Rated 5 out of 5 by from Amazing Little Machine! Yeehaw! I was highly skeptical about buying a battery-powered lawn mower to work on my 1 acre farm but really wanted one for the environment and ease of operation and this great little machine fits the bill. It's narrow path works in my raised bed garden, I am tired long before the 40 volt battery and the quiet, non-polluting, non-smelly operation is grand. It take a little muscle to push it but I'm ok with that (63 year old tiny woman). Also the start up is flawless. If you have seen Monsters Inc you know why I call it Mike!

Rated 5 out of 5 by from The Little Mower that Could! I bought this mower about a year ago for trimming some of the hard-to-get-to areas of our 1.75 acre yard. I quickly found that it was up to much larger tasks and I started using it, over the rider mower, on many sections of our yard. Then, about 6 months ago we bought a vacation home and I was in need for push mower. Again, the 16” cordless mower was the perfect choice and totally up to mowing the complete front and rear yards with battery power to spare. Quiet, smooth and well-built. Several of my neighbors have taken notice and a number have already purchased their own Greenworks cordless yard tools after witnessing and using my 16” mower. A big plus for me is how easily the mower is colllapsed for storage in the garage, taking up very little space!

Rated 5 out of 5 by from Quiet, Lightweight, and I'm very pleased. Being totally fed-up with a cheap Home Depot gas lawn mower that required annual servicing, and in seeing a neighbors electric mower, I saw a Facebook ad for GreenWorks and went on-line to evaluate. My lot is small so I took a chance thinking the 40 watt 16" would be adequate. I charged the battery for a full 24 hours and took the first mow. Quiet (no ear protection needed) and Light in Weight (didn't even break a sweat maneuvering it). Very pleased.

Rated 5 out of 5 by from Perfect for smaller lots With only a 5,000 square foot lot, with about 2,000 square feet of total lawn, this is the perfect mower. It's small, light, easy to maneuver, and the Gmax line has all the other tools needed with the same battery pack. Just one battery for me is enough for mowing, edging, blowing, and anything else I need to do. No problems after nearly 3 years.

Rated 5 out of 5 by from Great little mower Have actually only used it once so far. Very light compared to my gas mower. I was able to do my entire lawn, which isn't huge, in one charge. So I was happy about that. I also like that it is easy to adjust the height for the grass. It's a little louder than a fan, but quieter than a gas mower. I bought it to replace my gas mower which died.

Rated 4 out of 5 by from Works well for me Does the job with no smell, fuel spills and less noise. 80v, 144 Wh Battery lasts about 40 minutes in constant use. I pow about 1/4 acre of my lawn, and do it about every 10 days to 2 weeks. I charge all Greenworks products, Including 80v battery on Goal Zero solar panels and power stations. REALLY being GREEN.

I recently bought the 40V 16 inch lawnmower, have used it twice with great results!  But with the larger rear wheels extending further out from the chassis than the front wheels, it is very hard to get a close cut next to a wall. Design flaw?

Asked by: Yardman Bob
Hello Bob, Thank you for your question. For areas that mowers are not able to reach we recommend a string trimmer unit. Here are the ones that use the same battery platform as this model: https://www.greenworkstools.com/shop-by-voltage/40v/40v-string-trimmers

I own this lawn mower and I was wondering how it manages on wet grass and/or wet tall grass. Is it strong enough to handle it or would it be better to just wait until the lawn is completely dried?

Asked by: Nosh
Hello Nosh, Thank you for your question. This unit is ideal for small residential lawns. The unit works best on dry grass and when grass is under 4 inches in height.

I just received my 16" 40V Greenworks mower yesterday. It works great. My question is: When you first start the mower, the RPM starts out high for a few seconds, and then settles down to a lower RPM. Is this normal? It mows great with no problem.

Asked by: Alfred1
Hello Alfred1, Yes, this is a normal occurrence.

I have a friend who has model 25322. It has 6 inch wheels on the front but I cant seem to find 6" wheels on the parts link. Do you still carry them or should I replace both with 7 inch wheels?

Asked by: Erik Alejandro
Hello Erik, The part number for the 6 inch wheels is 31102488. This is from the owner's manual and it shows up as available through our third party parts site here: https://greenworks.ordertree.com/

Hi I see there is a 16 in. (model 25322) and 17 in.(model 2508302) 40V lawn mower. They seem to be priced the same and very similar overall, but they do look a bit different. I'm wondering if there is a difference or if one model is newer than the other?

Asked by: MRM87
Hello MRM87, Yes, there are some differences. The newer model 2508302 for example will has an updated look and updated internal electrics to more efficient and reliable. It also has a different height adjustment feature. We hope this information has helped.
