    • Wow. One of the most impressive tools I own.
Size: 21" SP Mower (Tool Only)
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) ... show more

    • I love mine
Size: 21" SP Mower (Tool Only)
I'm not sure I would be so happy with this mower if I didn't already have a Greenworks suite of tools - chain saw, pole saw, weed trimmer, leaf blower, hedge trimmer. And two chargers and four batteries. If I'm mulching and using the self propelled feature I have to replace the battery a couple times to finish my yard. But since I have so many and they charge so fast it is no problem at all. With that caveat, this is a fantastic mower. It runs well, mulches well, is easy to handle and super low maintenance. Very important, as I am a 60+ single woman, it is easy to start. Just press the button! I've had it for three seasons now and it just keeps going like a champ. The batteries can be a little hard to get out, but I find if I use both hands to do it they aren't too difficult to remove. I saw the zip tie battery hack in another review but even though my thumbs are getting a little stiff in my old age, it doesn't seem worth the trouble. ... show more

    • excellent mulching mower, decent battery life, can't charge batteries when hot
Size: 21" SP Mower (Tool Only)
This is a remarkable mower. Honestly, I'm shocked that some reviewers had such negative experiences. I have nothing but praise for the ease of use, maneuverability, effectiveness of mulching, and evenness of cut. It is difficult to compare battery usage, but here is our experience. We have a medium-large size yard, roughly 50' x 75', with rough grass and uneven terrain, and lots of planters that require time to mow around. Doing the whole yard on mulching setting, using almost no self-power, used the equivalent of 3.5 2Ah batteries over just under an hour. Using the self-drive feature would use more power. Maybe people have an unrealistic expectation of how much power they should get out of these lithium batteries. Only one of the two batteries drives the mower; the other one stays in the front compartment until needed, and then the operator has to switch them--easier than going to the garage for another battery. In summary, this is SO much better than a gas-powered walk-behind mower--so quiet, smooth running, virtually no maintenance, and no fumes to breathe. Yes, the batteries require charging, depending on how many batteries you have. The whole line of GreenWorks products for yard maintenance is the best, in my opinion. Note added May 27, 2019: After 2 months of use, a flaw in the battery system revealed itself. When a battery is depleted and placed on the charger, the green light on the charger lights up as if it were fully charged. Apparently, the battery has to cool down before it will take a charge. Some reviewer said to put the battery in the freezer for 10 minutes before charging; this seems to work for the 2 Ah battery, but the 4 Ah battery requires longer to cool off. Battery life: a 2 Ah battery lasts about 10 minutes; a 4 Ah battery will last about twice as long. Have reasonable expectations: the more you use the Self-Propelled feature, the shorter the battery charge; the taller the grass, the shorter the battery charge; using the mulching feature rather than side discharge will shorten the battery charge. Be grateful that you never have to worry about gas, oil, spark plug, carburetor, tune-ups, yanking on the cord to start it. The electric mower is not perfect but it beats gas for normal mowing situations. ... show more
