    • My 60 year old mom loves it.
Bought for my mother. She loves it and uses it every week for her yard. Can do her decent sized yard in one charge. And it's fast. She zooms it around. Easy to use. Performs as expected

    • Awesome addition to my collection of M18 Milwaukee Cordless Tools
Review Image by Ed Duran
Already an owner of other Milwaukee M18 cordless tools (drill, multi-tool, circular saw, sawzall, hedger, 6" and 16" chainsaws, leaf blower and weed eater) .. this lawnmower seems a natural addition. Yes, it is pricy, and Yes I love it. I'm able to mow my entire yard (about 8,000sf) using only half of the provided 12.0Ah batteries. I put them on the charger the night before mowing. And, of course, those batteries all fit the other tools (except the 6" chainsaw which uses the M12 battery). Side note: I've purchased "knock-off" M18 batteries which both failed just over the 1 year warranty; never doing that again. This mower provides 3 ways of handling the grass clippings: Bagger, Side Discharge and Mulch. Self propelled with variable speeds which allows me to decide how much exercise I need. Simple all-wheel height adjustment with a single lever. Headlight (4 of them), though I prefer to be a day-mower LOL. Height adjustable handle, which also folds flat and designed to store upright and take up much less space. Remember, no gas or oil to leak out, and none of that smell in my garage. It's also very quiet, and so easy to "start" and stop. The mower deck is made of metal and there are handles front and back which makes it so easy to move and store. I have read cautionary tales about not hitting sticks or ROCKS and the potential of damaging the motor housing, to which that end I am extra careful. Did I mention, No More Gas to Buy and Store? ;) ... show more

    • Kicks butt
Honestly this thing kicks butt, I got to say it. I didn't read the instructions or directions prior to use but just use my mechanic knowledge and I used it for a couple hours and the blade fell off mid-use. It was kind of scary but I'm sure somewhere in there it says torque the motor blading up before use. Other than that I would buy again. I'm a Milwaukee fan till I die. ... show more

    • Don’t think just buy it!
I mowed 13in of neglected green lawn. Wow! Besides for emptying the bag 30 times it ate the grass like a champ! By the way I set it at 3in instead of the highest setting. I am very impressed. Better than any gas rig I have ever had.

    • I like Milwaukee tools, but this one is a flop
Much more expensive than most others, so you would expect better build. But it degraded the mowing power in a couple of months…

    • Got it on sale for $899
Works fantastic. The batteries are nice to have if you are on the Milwaukee M18 bandwagon. Shipping was a little rough on the box, but the product arrived in perfect condition. The battery charger is fantastic and the giant 18.0 high output batteries are awesome. I mow my 1/3 acre lot weekly, I typically finish with 1/2 charged batteries. I usually unload about 5 bags total from the mowing. The side discharge and mulching plug fit great, but I always bag. The adjustable self-propel walking speed is fine-tuned enough to nail the exact speed you're looking for. The adjustable blade speed is interestering, where it will run the blade at a mild speed, but kick it up to full-power if the grass is thick. I'll often disable it with a press of the button, but its probably good if you're trying to extend your battery life. Yes, there are headlights, but I never have needed them. The mower is still loud from the blade spinning, but certainly no where near as loud as a gas mower! I was hoping this was light enough for my younger kids to mow, but its still heavy like a regular mower. I'd say weight is 80% of a gas mower, and 65% the amount of noise of a gas mower. If I can get this to last 3 years, it'll be better than any gas mower I've bought. Amazon has a sale on this for only $899 in the middle of winter. If you can get it on sale, its a big savings given the two giant batteries, and charger come with it. ... show more

    • Expensive but worth it
If you're a Milwaukee cordless guy (or girl) and have been considering buying this lawn mower I'd suggest spending the money. I will say that I actually have not mowed with it yet (middle of the winter in Maine) but so far I am impressed with the design, the quality, and the features of this lawn mower. I tried it out in my shop and couldn't believe how fast the self propelled speed can go! I feel like turning this into a ride on lawn mower! Lol! ... show more
