The GreenWorks Twin Force lawn mower, is powerful, quiet, and works really well. The GreenWorks mower is very nicely made. It’s constructed primarily of plastic, but it feels very robust and well screwed together. All of the components feel of high quality in the hand. Assembling the GreenWorks is easy; you just take it out of the box and attach the handle. The process involves no tools and takes only minutes. It’s an amazingly simple lawnmower to use. Once the batteries are charged you pop them into the two slots on the top of the mower. Then set the cut height using the sliding lever on the top – no need to set each wheel individually! Lastly, press the button on the handle and pull back on the safety bar. Once that’s done… boom… the GreenWorks comes to life. In use the GreenWorks is a revelation, especially if you’ve only used gasoline mowers. All of my previous mower experience was with manual-push gas-powered Craftsman mowers. They were powerful, but they were also heavy and loud. The GreenWorks packs all of the power of those machines, but it’s very light, easy to maneuver, and so quiet. My neighbor also has a cordless electric mower (an older Black & Decker) and even he commented on how quiet the GreenWorks is. It sounds no louder than a powerful fan on low speed, and even high speed is very subdued. Lastly, it’s such a joy to not have to get and store gas. Moving performance was quite good. First about my lawn, I have a .30 acre lawn that is basically flat and has a few patchy/bald spots underneath large trees. I never let my lawn get too long and mow it every weekend. In my case, 99% of the time the GreenWorks operates on its low speed, but when it hits a thick patch of lawn, or some twigs, it ramps up to high speed. It does this only until it clears the obstacle, and then lowers down again instantly. The switch between high and low speeds is automatic and not user controlled. I found my lawn to be cut very evenly and I did not have to do multiple passes to get an effective cut. I used the GreenWorks’ mulching feature and the clippings that were left behind were small and inconspicuous. I have yet to use the included bag, and have no plans to. Battery life is quite good. I’m able to mow my whole yard without having to stop and recharge. Once one battery dies the second battery automatically kicks in. One thing to bear in mind is that the GreenWorks will always draw power from the battery on the left hand side compartment first, and then switch to the other. I find it best to place the small battery on the left. This way after the small battery dies, and the GreenWorks switches to the large battery, I can pop the small battery in the charger just in case I need some extra juice. The charger is quite quick and even just a half hour of charging will yield a decent amount of run time. Thoughtfully both batteries have external charge indicator lights. If you’re using the mulching feature, you’ll want to remove the mulching plug in the back of the mower after each use, as it gets quite full of grass clippings. Be prepared for a bit of a mess when you remove it. I also like to clean the underside and body of the mower with a brush to keep everything clean. I store the GreenWorks in my one car garage. It fits between the wall and my car, and I fold down the handle to make it as compact as possible. All in all… a great mover, that’s also tremendously convenient.

The media could not be loaded. I ordered this lawn mower in mid-April and wanted to make sure we thoroughly tested it prior to leaving a review. We ordered the twin force 20" deck and the weed eater, but not in the package offered by Amazon. Unfortunately the weed eater uses a different battery and charger. Our previous gas mower ended up hitting a chunk of metal and warping the blade so bad that it couldn't be used. When all the local repair shops wanted $200-300 just to replace the blade, we decided it was time to get a new mower. I did a lot of research online prior to ordering this lawn mower. There are a lot of considerations when purchasing a lawn mower. What cost range am I looking at? What size is my yard? Do I want self-propelled or push? Do I want gas or electric? If I get electric, do I want corded or "wireless" aka battery operated. There are enough options for lawn mowers it makes me feel like I am car shopping instead of looking for lawn equipment. However, after a lot of research I logged into Amazon and saw this was a prime member deal of the day, which made it a better price and it is listed as the #1 best seller in "walk-behind lawn mowers", and with almost 1500 reviews with an average of 4.5 stars it warranted a look and some additional research. Initially, my husband was a little concerned about moving from a more traditional gas mower to an electric based mower (corded or battery operated). There were concerns about the power of the mower, if it would be able to "muscle" through any tough spots or weeds as we have a patch of clover and weeds that keeps coming back despite mowing, weed eating and chemicals. After watching several videos from real users and reading about the use of dual blades instead of a single blade we were intrigued. Another few hours of information about models from this manufacturer and we decided to order and try this mower. It comes with two different "strength" of batteries, however that has not been a concern as our yard size didn't require us to order another extended use battery. The current set up which is default upon ordering works just fine for our lawn and gives us 60-75 minutes of mow time when it's kept up. The time goes down just slightly if the lawn has had excessive growth. The lawn mower has been here and used about once per week minimum since mid-April and we absolutely love it! The batteries charge fairly quick. NOTES: You have to hold down the bar, keep it held down and then push the start or it will not start. The lawn mower will use one battery (light on by that "bay") and once it depletes then it will switch to the other battery, this is normal. There are two smaller 10 inch blades instead of a single blade. The lawn mower is NOT self-propelled, however it is light enough that's not necessary. My husband can push it and mow with one hand. The batteries show how much charge they have left. There are two options for the grass you mow, you can either put on the mulcher and mulch it back into the ground or put on the bag and empty it elsewhere. The mower will use two of the 4AH batteries, which gives a longer mow time up to two hours according to some reviewers, but it works fine with 1 4AH & 1 2 AH. Our batteries usually have charge left and we have a half acre here. The batteries are lithium ion and do not have a "zero point". So you don't have to charge full, let it die, etc. You just charge and go. The height adjustment is really easy to use. The lawn mower weighs about 40 pounds, the site states 42.5 pounds, but it doesn't feel like it at all. The best part? It's SUPER QUIET! I have a lot of 3rd shift workers near and as a previous 3rd shift worker I know that a lawn mower in the middle of my sleep schedule can be horrible. This is VERY quiet operation! I can carry on a conversation in a normal tone without raising my voice while mowing. I've attached a very short video just to show how quiet it really is. The weed eater is actually louder than the lawn mower is. OVERVIEW: This is a quality built lawn mower, which is light weight. It requires a small amount of assembly (no tools) and offers a reliable alternative to gas. The neighbors can barely hear the lawn mower and it gives about an hour or so of charge the way it comes. It's definitely correctly labeled as a best seller. It's a VERY good lawn mower! It has surpassed my expectations for a cordless/battery operated mower, especially for the current price.

Overall, a great mower. Lightweight, quiet, and powerful enough for most lawns. Easy to start, easy to maneuver, good cutting height options. Battery life is good— could be longer, but I bought two 6.5 amp batteries and with the provided 4 and 2.5 amp ones, I have enough to do an entire acre. Good value products.
