    • Works Great and Good Battery Time.
Style: 20" 40V Mower w/(2) 4.0Ah Batteries
I wasn’t sure what to expect from this mower as I honestly never thought I’d buy an electric one. However our Craftsman died earlier this year so I decide to give this one a shot since we’d had great success with other Worx products (their weed eater and blowers impressed me over the last few years). The set up was super simple and took just a few minutes. The batteries also did not take long to charge, so I’m assuming they were already partially charge. Start up is super simple (though it does feel a little backwards as you have to push the key over and then hold down the bar, instead of the normal bar first process). The biggest surprise was how quiet the unit is. It’s definitely quieter than the Worx weed eater and a huge difference over a traditional mower. Battery time, which was my biggest concern, turned out to be fine. At about 30 minutes the battery bar dropped to 1 light and you could feel the mower drop a little in terms of power, but it still cut fine and was still going 20 minutes later when I finished, so I don’t have much concern there for the future. Plus it also runs fine on my other Worx batteries, which I already have multiples of. I decided to try the smaller 20v Share batteries we have just to see and it worked with zero issue. The mower was very easy to maneuver and being lighter than a normal mower glides much easier. So far I’ve only used the mulching mode, but it cut very good and on the same level as a gas mower. My only complaint is once you turn the mower off, it does drop debris so I’m not sure the mulching was as good as our old mower. If weather stays nice (it’s currently above average temps in November here in Kentucky) I’ll try it out with the shoot attached as well. I also want to note that I bought this unit from Amazon Resale (formerly Amazon Warehouse). It was listed in “acceptable” condition. I was more than surprised when I opened up the plain, brown box and found what looked to be a good as new mower. I was expecting some type of damage like scratched or blemishes, but outside of some green grass coloring on the underside with the blade, it looked like I’d just taken it out of a Worx box from the store. ... show more

Style: 16" 40V Mower w/(2) 4.0Ah Batteries
This is a really nice little electric mower. I was pleasantly surprised at how much I like this. It seems to last around an hour under normal conditions. Maybe a bit more. I like that it has an auto turbo feature that automatically increases motor speed in taller grass and then backs off once in shorter grass saving battery life. The instructions are horrible. Only pictures and guess work. PROs: Lightweight, runs off ANY Worx batteries regardless of size. Height adjustment handle shifts super smooth. Batteries last a good amount of time. Comes with a wall mount charger. Cuts clean and even. Very quiet, a little louder than some but much less noise than a gas mower. Durable materials that seem like they will last. Easy push button/handle operation. Push button LED power gauge light shows how much battery life is left. CONs: Instructions are just pictures, no words. No option for side discharge. Only options are mulch or bagger. Handle can be a bit tall for shorter folks. Overall, I highly recommend this mower for your light duty, small yard projects. ... show more

    • 2 Mows in and So Far So Good
Style: 20" 40V Mower w/(2) 4.0Ah Batteries
Mower arrived 95% assembled, which was nice. Only had to unfold the handle, screw it down and then attach the cable clips. Super easy. Two 20v 4ah batteries came about half charged. I am impatient, so I put them in the mower and went to see what she could do. I don't have a large yard by any means...probably a 1/4 acre at best. I don't let the grass get too long but there are a couple of areas that are thicker and healthier than others. Mower started right up and is super quiet. It's lightweight so you don't need any kind of self-propulsion. A nice feature is the automatic 'turbo' that kicks in when the mower senses thicker grass or that it needs to work a little harder to get through a particular section...then turns back off when the easier/thinner material is recognized. I was satisfied after the first pass. However, I stopped because I knew I couldn't accurately gauge the battery life with two half charged batteries. So I charged them (took about 6 hours to fully charge from empty), plugged them back into the mower and attacked the lawn as I normally would. I'd say that these 4ah batteries got me 90% through. Lasted about a half hour+ and had a decent cut. It did die with a patch left over but luckily I have a Worx leaf blower and edger/weedeater combo for which I also have batteries. So I just plugged in a couple of 2ah's and I was done in 30 seconds. I would recommend getting at least a 5ah or even 6ah set of batteries if you have anything larger than 1/4 acre or thicker grass that'll require some more of the 'turbo' feature to be in effect. I'll start with the Cons since most people only remember the last thing they read in a review and I don't want to sour anyone's opinion of this Worx 21" cordless mower. Cons: Battery life isn't 'awesome' but is better than other cordless battery powered mowers I've seen/used in the past. I would just suggest investing in a 5ah or 6ah 20v set. Just be sure to measure the actual height of the battery versus the cavity of the mower because you are limited in the space. Some brands make thicker batteries in the same #ah. Another thing I noticed is that you 'should' make your passes slower than you typically would with a more powerful gas mower. It's not super powerful, but it is 'sufficient' and powerful enough. At first I made my initial passes as I normally would with my gas push mower. I noticed that it didn't hit every blade and even left some of the thicker stuff untouched. So the second go round, I went slower and it seemed to pay attention to everything at that point. Negative number 3 is the metal mower deck that extends past the wheels. I have some decorative brick edging around some flower beds and I noticed that the deck scrapes along them where my older mowers all had plastic wheels that would rub on them, thus protecting the deck. This will inevitably lead to the paint wearing away and rusting eventually. I'll have to keep an eye on it and maybe paint if it gets to that point. Last potential negative...DON'T LOSE THE SAFETY KEY. I've heard horror stories of people who break or lose the safety key that you need in order to start the mower. The proprietary shape isn't all that complicated to duplicate, but good luck finding one online or even getting one quickly from the manufacturer. Pros: Easy to use. It's super lightweight, the batteries are easy to install and remove and it took 20 seconds to fully assemble out of the box. Maneuverability is simple and you don't need any self propulsion on this one. Go slow and it'll do the job as long as you don't have any sort of super thick grass. This is definitely a mower for folks who have a smaller yard with regular grass that doesn't grow too tall/thick. It's also a more affordable option when compared to other electric/battery powered push mowers. I did my research and they're quite comparable to the competition in both price and performance. I went this route because I already had a couple of other Worx battery powered products that have served me well. No more oil changes and I just tossed out my gas can because the push mower was my last gas powered tool. I'm not pushing 'green' by any means, but this is nice now with fuel prices skyrocketing. You won't see me in a Tesla any time soon but knowing I don't have to go to the gas station because I'm out of fuel halfway through a mow on a Sunday afternoon is a good thing. I'll likely update this in a year to let you know how the batteries hold up and whether or not the blade needs sharpened. Thanks for reading and good luck! I do recommend! (UPDATE): As of 10/12/24, or about two months of use, the mower and batteries are still in good shape. However, the handle bar cushion wrap is ripping apart and the vinyl grass sweep I tearing away from one side. I have a small flat yard and don’t do any aggressive turns. This is all very simple movement here. So those two items are the only complaints I have so far. Luckily these are not necessary components and the grass is still being cut nicely. I would still recommend. ... show more
