Title: Wow. One of the most impressive tools I own.
Review: I rarely write reviews, but this product is so awesome in every way I just have to. I already own lots of battery powered tools and even have a very high-end all electric boat with Lithium batteries for tournament bass fishing so I’m no stranger to battery power. Despite this, I was slightly hesitant to order the 40v model vs. 80 vs. the Lowes exclusive 60. I was only worried about it having enough power and not bogging down in my very thick/dense yard. Worry not.We have a 2+ acre yard so I really got this to mow inside a small fenced pool area vs. using a riding mower and also to trim around some trees. A testimonial to the power of this mower - because I had put down seed with straw blankets on top in spots, i let the entire about 3k sq/ft area grow for several weeks. Most of the area was about 8-12” high. I thought for sure the mower would choke even on the highest (7) height setting. It had no issues at all even at the fastest self propelled speed and only 2 or 3 times even kicked into the auto sensing high power cutting speed. I mowed the area once at height 7 then moved it to 4 and redid it just to get it even shorter. I also used self propelled for a 40 yard walk to/from area including it pulling up a decent hill for half of that as a test.Pros (all super great)-easy 5-10 minute assembly out of box-everything very solidly built, like a “real mower”-powerful multi speed self propelled. Also, this works without starting mower, unlike gas mowers. So you can use it to get to/from job area limiting battery use..... or push it if u want.-very quiet compared to gas. 1/4 - 1/2(max) the noise-battery life? I used 5ah battery to mow that area 2x for about 20 min. Of mowing and use of self propelled. It took 1.5 hours to charge battery so I’d estimate I used at most 50% of battery (they say 4 hrs to fully charge). Calculate that out to estimate of let’s be conservative and just say 40 min. Of run time. With 2 batteries I would think you can mow a 1/8th to 1/4 acre area.-7 easy mowing height adjustments-easy everything ... start, self propelled, instructions, assembly-no gas, oil, dirt, setup time, maintenance.. just walk out get mower, push button, mow-winterize - e.g. gas treatment, run gas out, etc.... nada-grass bagger/bagging great, clean cut-batteries: easy in and out and even are to hold spare. Please ignore all the complaints I see within of people saying the battery is hard to remove once inserted (I.e. that it’s hard to press the release and u need a tool to help with that). Absurd comments unless you have zero wrist strength and your fingers are so big your hand doesn’t fit in a mailbox.-battery can be used in the other green works tools. ( I also,bought the equally awesome blower and trimmer. Trimmer tested with using all my existing Ryobi attachments which is nice if desired.)Con-with thick real thick yard, I would say height adjustment below 3 will drag mower deck in front. (Too low)

Title: What an absolute unit! I love everything about this mower.
Review: I have several Greenworks electric tools that use a 40V battery, so I was able to use the same batteries in this mower, which saved me some money. It takes two batteries to mow my lawn, so having the storage slot for a spare battery has been so helpful! Much easier than having to stop mowing, remove the battery, go inside (wiping off the grass from your legs and shoes first), put the battery on the charger, and grab a fresh one. I have been having chronic pain issues that make more intensive chores difficult, and I really needed to upgrade to a self-propelled mower if I wanted to continue mowing my own lawn. Even on my thick uneven lawn, this mower performs beautifully. It was easy to set up on my own and I love the variable speeds.The quietness is one of my favorite features of an electric mower. I can mow my lawn and easily talk to someone on a headset without having to yell, or listen to podcasts without having to crank up the volume. It also means I can mow in the early morning or late evening without disturbing others. My neighbor even asked me when the heck I am mowing my lawn, because she never hears me mowing it but it's always short and tidy! Her riding gas mower, however, you can hear all up and down the block! And there's something especially annoying about going outside the enjoy a picnic lunch with your spouse or to relax in the hammock with your cat, and a neighbor decides that right then is a perfect time to haul out their noisy gas mower!I've read reviews stating the battery is impossible to remove from this mower. Being familiar with Greenworks tools it was not an issue for me. However, if you are having trouble with it being a little more difficult than it feels like it should be, try tipping the mower onto its side so that gravity isn't working against you.

Title: It is easy to control, quiet, green, lightweight, and the lawn looks good afterward.
Review: We like it this mower. I gave this lawnmower to my daughter to mow her medium-sized urban lot.PROS and general comments: It's easy to control the speed. The variable speed control and its effect are user-friendly. Starting is easy ... if you read the instruction cartoon on the handle. This mower is NOT going to accidentally start. One battery will not do the entire lawn, but maybe that's a good signal to take a rest when the mower stops. We get full power until the very instant the battery gives up the ghost. I will buy a second battery. I'd rather have a brushless motor, but those cost more, as well. It's almost fun to mow using this mower. The mower is quiet. You can probably mow when neighbors are sleeping. The mower can be stored vertically, but we've not needed this feature. I like not having to stress over gas stabilizer or getting Ethanol-free gasoline. I like the feeling of emitting our greenhouse gases in a power plant elsewhere instead of my daughter's yard (hoping that the power plant will someday be green, as well).CON 1: The rear wheels lock when I pull the mower toward me. I've found that those wheels will unlock if I start the pull in an 'S' pattern. I'm not sure if this is a feature, a defect, or a safety thing. Every other power mower I've used allows me to pull it toward me when needed.CON 2: The battery is difficult to unlock and extract, especially if you have sweaty fingers. Others have mentioned putting a fishline loop around the battery before inserting it. I will try that, but I still would have to unlock the battery with a free (large) thumb / finger pinch within a tiny space. This, while pulling the heavy battery upward.

Title:
Review: La altura de corte no es intermedia, o queda largo o muy corto, debería tener un nivel adicional, en cuanto a la batería debería durar un poco más para el costoBuena calidad y buena en estética, sí tiene impulso propio suficiente
