Bottom line up front: This mower is phenomenal. Even though I've only had it a few weeks, but I've already abused the bejeesus out of it... I'd gladly buy another one tomorrow. Look at the photos I've attached. I also purchased the attachment capable weedeater. It's great too, but the mower is the best mower I've ever used.
I have a 3/4 acre lot. The 1/2 acre of my property that is grass was no problem at all. Using a 4Ah and a 2Ah battery, I only have had to pause to charge once - and that is only because I let the grass get really high. It was knee high in some places.
That being said, over the years I have let about 1/4 of my lot has been go wild. I've called it my "suburban nature preserve." It was to the point where I was considering hiring a professional to clear the land. It consisted of raspberry bushes, greenbriar vines, english ivy, and hundreds of magnolia, oak, and pine saplings. Some of these saplings were 6' tall.
The other day, I took a pass through a section that was mostly ivy and greenbriar with no issues. Gradually, I worked up the nerve to take it through the really thick stuff. This mower did not disappoint. The only time it stopped was when I hit some hidden plastic sheeting and when the battery died.
It mulched literally dozens of saplings 3/4" thick and 6 feet tall while making light work of the brush surrounding them. I've never seen a mower be able to handle this type of stuff and I'm absolutely amazed.
I just used this mower for the first time and I am very happy with it. It worked very well and left my lawn looking so even compared to my last gas mower. It takes about an hour to mow and the battery still had some charge left. I do not regret the purchase.
Purchased the 21" self-propelled model. Honest review in my opinion. Assembly directions were a little lacking, but able to complete using youtube video. Mower is fantastic for cutting and noise level. Only downside, the self propelled rate is a moderate walk on highest level and snails pace on lowest level compared to a self-paced mower. Love how compactly mower folds up to store. Also, saw online it is recommended to spray cutting deck with silicon spray to ease cleanup. No water cleanup.
I have only had the chance to use this twice since i purchased it. I was able to get an hour of operation out of my 1 year old 2A battery and was very happy that they runtime was as advertised. I was also impressed with how quiet the mower is. I was wearing some bluetooth ear buds and could barely hear it over my music which was not up very loud. Seemed to have plenty of power for cutting and the self propelled mode. One of my favorite features is the way that it stores. Being able to fold the handle down and store the mower upright is a huge space saver. I'd give it 5 stars but i need to use it over at least a season to see how it holds up. Great job Greenworks. (i also have the 18 in chainsaw and the handheld leaf blow and those work great too!)
I used 80 V self propelled lawn mower past 2 springs to whack 3' tall weeds with up to 1" stalks. While it won't do that and climb uphill at the same time, there's no problem munching huge weeds while going downslope. And height adjustment allows passing over rocks up to ~3" rocks. Great tool!
I replaced my well used gas powered mower with the 80 v self propelled GreenWorks mower. I mow about 1/3 acre, and need the self propel feature less than 1/4 of the time. With the 4 amph battery purchased separately, I can finish with a battery needing a recharge. The mower is light and easy to push. With my GreenWorks blower, string trimmer, and an edger attachment, all my lawn care needs are satisfied. I would recommend this mower even if you think you don't want a battery powered mower.
