    Great mower for the money. Wear hearing protection even though it's relatively quiet.

    Quick review. Arrived in mftr's box ONLY. Shame on Amazon. But luckily, nothing was damaged. I opened the box, assembled it w/o too much effort (all but one thing was just common sense). It looks great, is fairly light weight and pushing it w/o self-propulsion is easy thanks to said light weight AND large wheels.It works great. Battery actually lasted long enough to cut a large backyard with some to spare. Didn't have to charge it but I pushed most of it instead of self-propelled mode. It cuts fine. auto adjusts when the grass gets thicker and you can adj the speed of pulling and there's a tur

    This is a great mower!

    I never expected to write a 5 star review for this mower, but alas here it is! My old Toro gas mower died 2 weeks ago and I ordered this 80v Greenworks model because it appeared to have more power than the (2) 40v. to go up hills, and yes indeed it does! It came overnight, so I was able to finish the mowing from the day before. Setup was a breeze with only a few parts to assemble, it was ready to go in about 20 minutes. The self propel on full power (yes, it's adjustable if you want to go slower or on flat land) worked just as good as my old Toro, you can see the steep backyard in the photo. I

    Worth the money

    Great mower! The cut is clean and the mower is easy to push. I have 1/3 of an acre and get most of it cut with one battery charge. Turbo fetched is great too!

    Not bad

    There's a bit of a learning curve, lol. Don't wait til you have to turn to practice that. To back up, you have to release self-propel levers, give a slight push forward, then go backward. I don't like that. Battery didn't last as long as advertised, but maybe that's my grass. Battery charges FAST, which is great. Self-propel feature works great, and is adjustable. It's not fast or slow, that's nice. It seems to have some power. I have a 0.66 acre double lot on a corner, so big yard. This is easier on me than the 60V push mower, but my shoulders and biceps are pretty sore after cutting about a

    Great mower with lots of power.

    Assembly was super easy. A couple of references to the instructions and it was ready to mow. The self-propelled option is worth every penny. This is a quality product and worth the price.

    This lawn mower power exceeded my expectations!

    I am surprised and delighted by the power, efficiency, and ease of use. I purchased the Greenworks 80V 21” Self-Propelled Cordless Lawn Mower when my old gas powered mower recently seized up and stopped working. I’ve always been very skeptical about electric mowers having comparable power and ability to cut through thick Saint Augustine grass. To my surprise and after about 8-10 lawn cuts, I’ve been totally convinced and happy with this mower. I have about 1/4 acres of Saint Augustine grass - and the battery lasts for at least 3 mowings and cuts through thick wet grass like butter. Because it’

    Great Mower, Horrible Batteries

    Great mower, but plan on spending hundreds of dollars on batteries, as I need 2-1/2 batteries to mow a little over a quarter acre of yard. I figured it out: the price for my three batteries, I could have purchased 10 years of gas, so if value and not switching out batteries is what you are looking for, this is probably not the mower for you.On the flip side, if you want a quiet mower with a good cut that you don't have to change oil and air filters, this is a great pick.
