Alright, time for my final review of the Milwaukee M18 mower. tl;dr: it did not live up to the hype for me, it was more difficult to operate than it should have been, it has several design flaws, and I was disappointed in Milwaukee's handling and it damaged my trust in them as a brand. All of this especially given due to the price point, just under $1,200.

Image


I want to preface this by saying I like to do a lot of research, especially on big buys like this one. I am coming from a Honda HRR from 2016. I literally spent weeks researching this one... I compared several different models (both gas and electric) from Toro, Honda, and Milwaukee. I watched lots of YouTube videos. I scoured forums like reddit and The Lawn Forum, searched in Facebook groups focused Milwaukee tools or lawn care, and on occasion even reached out to users to see how they liked their M18 mowers now.

The YouTube reviews on the M18 mower were overwhelmingly positive. The only critical flaw a YouTuber I could find that was pointed out was about the thumb lever for the self-propel being awkward and not adjustable. The forums didn't have much to say about the M18 mower. And the users I reached out to on Facebook to get an update either didn't respond, or gave a generally positive review.

Over the past two years, I've been slowly moving from the DeWalt platform to Milwaukee just because they had more tools and attachments for outdoor power equipment. I wouldn't say I'm a fanboy or a loyalist for either brand, I just like stuff that works. I had pretty good experiences with Milwaukee so far though, so I was excited to bring the M18 mower home from Home Depot. With this and the reviews I read, I expected to maintain ownership of this mower so I immediately unboxed it, took the blades to Ace Hardware (my preferred Milwaukee/Toro dealer) for sharpening, and chucked the cardboard boxes after assembly.

Image


My first impressions were positive with how light the machine was and how quiet it was. But I quickly identified some items that I considered to be design flaws:
  1. The mulch plug. It's literally held in by the friction of the rear door. On the first mow it wiggled and let clippings pour out and collect on the rubber flap. After about the third mow it finally "sealed up" with wet grass clippings collecting in the deck. That's the only way it was resolved. If I cleaned the deck out, it's the same issue again since that maintenance task would have broken the "seal".

  2. When I decide to bag instead of mulch, grass clippings then come out of the TOP of the bag and collect on top of the bag. Most of them still collect in the bag but it's still just a dumb problem to have. No good way to fix this.
  3. I was excited to have one lever to select the deck height on all 4 wheels, but good lord that lever is unnecessarily and obnoxiously large. I don't think many of us use this lever often enough to make it so, uh, accessible. It sticks out so far and it was always getting caught on things like chain link fences or retaining walls. I had to change the way I mowed and be more cognizant around the edges and both of these things slowed me down.
    Image
  4. There is no variability of the speed when using the paddles on the handlebar for self-propel. You're either going 0 or the speed that's on the speed selector and there's no in between, like if you're negotiating a curve or a corner. The speed is either too slow or you feel like you're chasing the machine to catch up with it. It also makes the mower "jump" when you start the self-propel.
  5. Especially when trying to navigate and maneuver in corners, the self-propel makes me feel like I'm negotiating with a terrorist. The M18 mower does not like to perform in short bursts like these small areas. I engage the self-propel but it doesn't want to go anywhere. And 75% of the time when I need to back up, for some reason the rear wheels lock up and I'm dragging the wheels through the grass, trying to maneuver the space. I have to stop, move it forward manually a little bit, stop and wait, and then pull it back. It makes corners unnecessarily difficult and becomes a time suck in areas where there's lots of objects to navigate around. It slowed me down tremendously and in these corners it was a little tough on the turf.
  6. By far, my biggest and most consistent complaint has been the cut quality. On day one, I took the blade that came with the M18 mower to a local Ace Hardware to have the blades sharpened since they were not already sharp from the factory. Still, there are plenty of "stragglers" -- blades of grass that don't get cut by the M18 mower and stand tall and proud. To mitigate this, I overlap the passes more than I should, which ends up taking more time. And on about half the mows I end up doing two passes -- one at a higher height and the other at a lower height to try to cut everything. The M18 mower still doesn't cut everything consistently. This is using high lift mode and standard mode, it still doesn't make a difference. It looks like garbage and has become a huge time suck to get it looking decent.
I ended up using their turbo or "high lift" mode on every single mow and still had cut quality issues. Sometimes it was so bad I just double-cut but of course that doubled my time and effort to mow the lawn.

Image


Battery life was ok, if I used the standard mode I could easily get both the front and back mowed on one charge (about 5k sq ft). On turbo/"high lift" mode I could get MOST of the front and back mowed in one charge. I could just go and get one of my lower-capacity batteries to finish up that mow. If I had to double-cut either the front or back, then no way -- I'd have to finish the next day.

So I tried figuring out ways around it for a few weeks but I just couldn't make it work and kept getting disappointed. So I e-mailed Milwaukee via their website with the same exact points as above (some of the items I actually copied-and-pasted from the e-mail into this post!). I didn't hear anything.

Image


One day, Milwaukee made a post on their Instagram about their M18 mower. I just made a short comment under it about how I was disappointed in the mower. A random user -- looked like an electrician -- asked me for more details. I brought up the points above briefly and they were pretty bummed about that since they were interested in the mower as well. I even admitted that some of my feedback might be nitpicky because I am into lawn care and what's important to me might not be important to anyone else that isn't into lawn care.

The next day, Milwaukee's social media team DMed me for my contact information to reach out to me after seeing my comments. I sent them all of my info and said someone would be in touch with me the next day.

That same day, someone replied to my comment on the Instagram post and asked what my issues were. I responded that I posted my grievances in the comments up above since I didn't want to re-type it all on my phone. That user said no you didn't and said either I deleted it or Milwaukee hid my complaints. I viewed the comments on that post with a different account, and sure enough my first comment was visible but the comment with my actual feedback was not visible.

I was pretty disappointed it happened that way. I understand that a company doesn't want negative feedback on a post where they're trying to sell something but from my standpoint that is really dishonest of them and demonstrates a lack of integrity. It has permanently damaged my trust in Milwaukee as a company. Now I understood one of the reasons why I found very little critical feedback of the M18 mower.

As promised, a Milwaukee CX Technical Support Advisor got in touch with me the next day. I answered her questions and provided more detail. These exchanges went on for a few days.

The representative thought the issue with the self-propel locking up might have been a safety mechanism. While she admitted "it will not fix 2/3rds of the pain points" I had experienced, she could provide a prepaid shipping label to send it to a Milwaukee service center to check the mower's self-propel issue. She also considered sending me a new set of blades to try to fix the cut quality issue, but since I took the blades to a Milwaukee dealer for sharpening on day one, she admitted she wasn't confident that this would fix it. I asked how long the turnaround would be since I don't have another mower, and she stated they try to make a two-week turnaround. I asked if I could just send it to Milwaukee for a refund, and she said "Milwaukee Tool is unable to cut a check or refund to end-users."

Image


Look, I hate returning things. It's wasteful and it usually hurts someone in the transaction. To me, it's a last resort. But I was really disappointed with the mower in general, the representative was completely honest that these are issues that will likely persist, and the way Milwaukee hid my honest but polite feedback had just really soured me on the brand and I didn't want to deal with this $1,200 problem anymore.

I went to my Home Depot to talk about returning it to them, even though it's been used and I don't have the boxes anymore. I explained my issues. The associate said they would take it back and they'll return it to Milwaukee since it's still in the return window (90 days for electric tools, 45 days for gas). Even though it's a giant corporation, I felt bad that my store might lose money on the return. She said they'll probably still receive a credit from Milwaukee for the sale. I said I'll clean up the mower and bring it in a few days later.

So I brought the mower in a few days later and someone else helped me with the return. The guy was convinced this mower was a special order and that the store doesn't sell these. I guess they don't sell very many of them? I showed them my receipt in the Home Depot app and they popped my receipt number into their register to process the return and as soon as he saw the receipt total on my original purchase the guy literally said "oh my god" because he couldn't believe this mower cost $1,200. I think he agreed at that point that my complaints were valid for a mower at that price point.

Image


So they took it back, no other questions asked, and I feel lucky to have been able to return that mower for a full refund and wash my hands of that problem entirely. I've since switched to a TimeMaster, which, yeah... I'm cracking nuts with a sledgehammer for a TimeMaster on a 5k sq ft lawn. But I know what I'm getting. It's a reliable machine with a good quality cut with a machine design that's been refined and proven over several iterations.

Image


As for Milwaukee, I'll continue to buy tools from whichever manufacturer makes the most sense to me, and I'm still straddling Milwaukee and DeWalt platforms. But it's hard for me to deny that Milwaukee supresses critical feedback on social media and a lot of "reviews" of Milwaukee equipment are from influencers who are bought and paid for and have since noticed that many of these influencers no longer mow with the M18 mower. I wonder now if those forum and Facebook users I reached out to that didn't respond for an update ended up dumping their mowers.

Awesome review bro, detailed and comprehensive in true TLF fashion. I likewise have been trying out battery mowers and am currently playing with the M18. The issues you bring up are EXACTLY ones that i've noticed as well, and I've contacted their customer support dept regarding the cut quality specifically. They sent me a high-lift blade which may or may not have helped (can't tell much but so far so good). The obnoxiously big adjusting lever LOL has likewise caught my eye but only because the slots that are supposed to hold the position are more like indentations and i've had it slip out of position once. But I do love the one-lever adjustments! I mow my TTTF on max height, and sometimes in the same day I mow bermuda at the lowest setting. That in itself is of great value to me. In comparisons to the Toro 60v Milwaukee does a super job when it comes to adjustments! Just never realized how big the lever was until this post of yours. :)

As for the mulch plug.. what a weird concept this is! If my head wasn't attached to my body I'd probably misplace it... how do they think something so important is going to remain accounted for when the decision to mow vs bag changes from season to season? Make a built-in mulch flap like everybody else and call it good, but no, they put a removable plug instead. Sheesh. You were likewise spot on about the self-propelled issue.. i find myself playing with the speed selector knob while mowing, trying to find a perfect speed so it doesn't run away from me when I first engage. I try to feather it in most times but it's very touchy. One push and you're doing 60mph in 3.5s!

Some of the pros ... I love the weight of this mower (not too light & flimsy that it floats on your turf, but not excessively heavy either). The power is by far the best of any battery mower i've tried! Love the lights on it as I've been known to mow late into the evenings. And I especially love the 1-4" height adjustment and one-lever control. Still not sure it has the suction power to replace my HRX217 though, but this is the closest it gets.

$1,200 for a mower wouldn't raise an eyebrow on this forum, but I agree, for the money, you should be over the moon ecstatic with it. And their marketing was pitching this unit to commercial lawn service operators. That's a hard sell given the battery life and performance you describe.

Just to satisfy my curiosity, why did you go with a TimeMaster vs a Super Recycler? 30" stripes?

Yep, that's pretty much it! We're hoping to sell my girlfriend's house this year after her tenants move out but it's a semi-rural lot with long yards and I don't know how long I'll be responsible for mowing it in the meantime so I used that as justification too. I also put a Check Mate striper on it.

Great detailed review @kds.

I’ve been looking at the M18 mower and EGO’s LM2156SP. This will definitely help my decision making process.

I have Milwaukee hand tools and have used their Quik-lock equipment in the past, but moved off due to M18 multi-head melting my batteries. I’ve since moved onto EGO for my battery OPE and haven’t looked back.

With this being Milwaukee’s first generation mower I was a little hesitant on jumping in for such a pricey piece of equipment and glad I have waited. Maybe in future iterations they’ll get a solid product available.

I’ve read numerous users complaining about the mulch plug, extremely dull blade installed and poor quality of cut. Thank you again for your detail review of the mower and experience with Milwaukee’ social media.

While a bit off topic I'm curious about the "melting my batteries" . I have noticed a weird issue with my Qui-lock head and batteries. Intermittently it just quits until I release the trigger and squeeze again. Then, awhile later, it will do it again. And so on. I've marked my batteries thinking I might have a failing one but I've noticed it will happen with a few of the batteries. I'm kinda suspecting the head. Is there info, threads or something that go into more detail or just what has happened to you?

Just a couple thoughts, since I have experience with an electric Toro Recycler.
I could be seeing the photo wrong, but it looks like you were mowing some pretty high grass.
Even with my Recycler, if i'm cutting high grass, removing more than 2.5in or, I also get a few stragglers that the air currents don't pick up.
In one photo, it looks like the grass was very damp (or juicy?) and caused a ton of buildup on the deck underside.
That could also cause cutting quality issues if it's damp.

That's what I would think too, but it wasn't anything out of the ordinary. Remember I'm using my Honda as the benchmark. I keep my TTTF pretty tall especially in this part of the season and it's pretty thick and healthy in some areas (mostly in areas I have been giving a lot of TLC to over the years and has better grass varieties than the older parts of the yard), but I do cut it regularly. I even gave the M18 the benefit of the doubt and cut it twice just to make sure that wasn't an issue, but the issues were persistent. I don't cut wet grass, so any moisture in the grass is just a byproduct of being thick.

LM2156SP owner here and I’ve been pretty impressed with the mower. I’m coming from a Honda HRX217 and expected to be let down by the EGO mower.

I’ve had this mower for about six weeks now and starting to get accommodated to it. It’s very different than the previous mowers I’ve used in the past with its weight, self-propel mechanism and the fact that it’s a battery mower.

I mostly bag my TTTF/KBG/Rye mix a 3” height and this mower has been great. I’ve mulched a few times and it’s performed great as well.

I've owned the Milwaukee 18v mower for 16 months. My experiences are similar to yours. Coming from a Toro Super recycler I was shocked with the poor cut quality and cheesy attachments. I've learned to live with with those shortcomings but the real problem is the batteries. After a year they refuse to charge more than 3 bars (75%). When I first got the mower I could mow my entire back yard on one charge. Now it takes 3. Replacement batteries are $$$$ 250.00 apiece. An expense of nearly half the price of the mower every 1.5 to 2 years! They have to be kidding!

Ummm... if you registered your product and batteries with Milwaukee that shouldn't be an issue... they warranty their batteries for two years, not just one... I had one battery not last the two years, it was only a month before time was up. I contacted them and quickly received a replacement. So if you are only getting 3 bars after a year, I would contact them. FYI, I would also not store batteries in an unheated garage, the cold does damage all batteries. But I went with Milwaukee for the fact they stand behind their products, I had a circular saw, almost 5 years old.. its trigger stopped engaging... sent it back on their dime, they repaired it and sent it right back. I used to be big on Makita until I had an issue with a table saw... they acted like whatever was wrong with the saw was my fault, like I did something wrong... I had only used it twice.. the second time I could smell something electrical burning when I started it, before even starting to cut, I immediately turned it off and unplugged it. After them acting like it was my fault, I was told by one of the old guys down at the commercial tool rental place, Makita had several fires break out with their table saw model I had due to an electrical issue that they were well aware about. I get sometimes issues come up in the real world and need to be fixed, but they sent me around and around, tried to get me to pay for return on a six month old table saw that had only been used once and turned on a second time and had electric stuff melting down inside. Customer service goes a long way for me, if I deal with a company that gives me the run around, I am done. So far the two experience's I have had with Milwaukee have been great and completely easy... they didn't act like I broke it and they didn't try to get me to pay for it either or the return, so even with some of the weird things about the mower, I would rather deal with them than some of the other companies.

So I would have to agree with another responder on here... the first thing I thought, the lawn looks pretty damp. I don't care how good a mower you have, a damp or wet lawn won't cut evenly. Then I looked at the picture that is focusing on the underside of the mower, showing all the grass stuck in the mower... I thought again, that looks pretty damp, but then I noticed, the wet wheels! Grass doesn't stick to wheels unless you ran over dog poop (LOL) or the lawn was wet. There are some other clues in these pics that clues me in that it was a wet lawn, the grass stuck in the backside of the wheels, grass stuck to other parts of the mover like that rear flap and the front pin... grass doesn't normally stick to these parts unless it was wet.

Toro is a great mower.. heck, I live about 30 miles from their factory here in Wisconsin... but I am guessing if you tried to mow the same lawn side by side, the Toro would be just as gummed up. I don't think I have ever waited to mow my lawn until it was that long... heck, my neighbors would be complaining away if it was half that length.

I can pretty much echo the original posters feelings about the Milwaukee M18 electric mower. It replaced a John Deere JX 75 mower I had owned for over 2 decades. I purchased the Milwaukee mower in May of 2022. I was Immediately disappointed in the cut. It was very uneven. I ordered the "High Lift" blade, had it sharpen per online recommendation. The cut was still very uneven.
When fall arrived I used the mower it get leaves on the lawn up as I have always done. The results were TERRIBLE! The mower has very little suction which I assume is why its lawn cuts are so uneven. I have had to borrow my neighbor's gas powered Toro to get leaves up in the fall.
The first summer I owned the mower I would mow my 5000 foot lawn and the charge level would be 50% when I was done. By the middle of the 2nd summer I owned the mower I could no longer do my whole yard without the batteries dying. The M18 batteries cost $250/each to replace. So, $500 or half the original purchase price to replace the batteries!
I like many of you have owned many Milwaukee tools over rte years and love em. However, Milwaukee's electric mower is a major disappointment and a black eye for the company .
