The RYOBI 20-inch 40-Volt Brushless Lawn Mower is lightweight and maneuverable, and it is better for the environment than a gas lawn mower that releases harmful emissions. Besides mowing, you most likely need to edge your grass, trim bushes and cut tree branches.

For other models we’ve reviewed, check out our full round up of all the best electric lawn mowers, or if you don’t want an electric model, head to the best gas lawn mowers.

In addition to being compatible with other RYOBI machines, this mower’s lithium-ion battery lasts up to 40 minutes on a full charge. If your lawn is well-maintained, this gives you plenty of time to mow your yard before you need to recharge the battery. The mower can house up to two batteries. This allows you to mow for an extended period, especially handy if you have a larger lawn. You may find the batteries drain more quickly when you mow long or thick grass. Fortunately, RYOBI’s batteries recharge faster than others – you can charge a battery to full capacity in 90 minutes.

RYOBI 40-Volt Brushless RY40180: What you need to know

The RYOBI 40-Volt mower is best for lawns that are half an acre in size or less. The mower has a 20-inch cutting path and seven cutting-height positions, ranging from 1.5 to 3.75 inches. You can easily adjust the height with a lever located on the left side of the mower deck.

When you finish mowing, the handle folds down, which makes the mower easy to store. This is extremely helpful if you have limited space in your garage or shed.

RYOBI 40-Volt Brushless RY40180: Features performance

Unlike gas-powered mowers, the RYOBI 40-Volt starts instantly with the press of a button and runs quietly without disturbing your neighbors or emitting noxious fumes. It isn’t self-propelled though, so you need to put some work into moving it around.

This is a good electric lawn mower if your goal is to be environmentally friendly. It comes with a mulching option that grinds down grass clippings so you can reuse them for gardening instead of throwing them away. It also frees you from the yearly maintenance and fuel and oil that traditional mowers require.

This mower weighs just 55 pounds with the battery installed. Because it’s lightweight, it’s somewhat easier on your back and knees. Still, it may be difficult for some to maneuver on hills or steep grades because it isn’t self-propelled. This RYOBI also does not have a side discharge. It comes with a rear bag that collects grass clippings as you mow.

Ryobi 40V Battery 21″ Lawn Mower Review

Ryobi battery lawn mower review is sponsored by Ryobi Tools. I have been provided with product. All ideas and opinions are my own. This post contains some affiliate links for your convenience. Click here to read my full disclosure policy.

It is finally starting to look like spring around here in Utah. Sometimes we get teased with warm weather, and then a snow storm will hit the next day. Ha ha mother nature keeps us hopping.

As Spring brings in the good weather, it brings lots of yard work with it!

I don’t know about you, but when I do yard work, I just want my equipment to work so I can get it done. I hate messing around with pull strings, carburetors, mixed gas and regular gas. When I was a kid, I would wait until Dad came back for lunch to start the weed eater…I could never start that thing on my own. Oh and the tiller, well that was always a challenge.

As battery powered lawn equipment has evolved, I’ve always been drawn to it. No messing around with engines, just plug in the battery and get to work!

Ryobi 40V battery powered 21″ self propelled Lawn Mower

This lawn mower is awesome. It runs better than all of our previous gas mowers, plus it is so much quieter.

This mower is so easy to use, but first things first…charge the battery.

Once the battery is charged, just open the lid and slide the battery into place. There is also an on-board storage spot for a second battery.

ryobi, 40-volt, brushless, ry40180

To start the mower, pull back the black bar.

ryobi, 40-volt, brushless, ry40180

Then push the center green button on the handle. That’s it, now the engine is purring and the clippings bag fills up with air.

ryobi, 40-volt, brushless, ry40180

You can choose to push the mower, but if you would like assistance (and why wouldn’t you), there are green handles to engage self propelled mode. The self propelled speed is adjusted with a slider in the center of the push handle.

Min is a nice leisurely walking speed, and well Max is for someone with much longer legs than I have ;-).

ryobi, 40-volt, brushless, ry40180

And just like that the lawn mower and I are ready to get to work!

ryobi, 40-volt, brushless, ry40180

Additional Adjustments

The blade height is super convenient to adjust, pull the trigger and lift or lower the handle on the left side of the mower.

ryobi, 40-volt, brushless, ry40180

The height of the lawn mower arm/pushing handle can be adjusted for the operators height. The lower setting is perfect for me, I’m 5’5″ish.


One of my most favorite features about this lawn mower is the fact that it can be stored UP RIGHT!

ryobi, 40-volt, brushless, ry40180

We are always tight on garage space, and the fact that this Ryobi lawn mower can be stored so compactly is amazing!

Testing the Mower

  • As I mentioned before, the Ryobi brushless 40V lawn mower has plenty of power. There was no bogging down of the engine, it really seems to run as well as a gas mower.
  • Battery life – my yard is just under 0.4 acre acre and having the mower blade height on the second lowest setting. I can get over half of my yard done with the 7.5 Ah battery. Having 2 batteries would be perfect for me. If I set the blade higher, I could get a longer run time.
  • I wouldn’t hesitate for a minute to recommend this lawn mower to a friend.
  • It has all the power needed to cut thick grass.
  • The mower has many thoughtful features, easy blade/mower height adjustment, easy start, easy self propel adjustment, ergonomic adjustment of the handle, etc.
  • It is quieter than a gas powered mower.
  • The clippings bag is a generous size and is easily removed and replaced.
  • This mowers icing on the cake is the compact storage, man I love that feature!

Ryobi Mower Long Term Review

ryobi, 40-volt, brushless, ry40180

After three years of use, and extensive research on the competition, I believe the Ryobi 40-volt cordless lawn mower is the best mower for the money, for people with small lawns. My mower is the RY40170 20″ brushless mower. It came included with two 4 amp hour batteries, is capable of mulching and bagging, only weighs 44 lbs (plus battery), and comes with a 5 year warranty. It has seven cutting height adjustments (from 1.25″ – 3.75″) that you can easily adjust with a single lever and the handles fold down flat making it super easy to store. This is especially helpful if you have limited space in your garage or shed. Having two batteries included is a big bonus. Based on the reading I’ve done, with the included batteries, the Ryobi has the longest run time of any cordless mower (over 1hr). With a robust 40 volt ecosystem, its batteries can also be used to power other Ryobi lawn equipment, such as a string trimmer and blower.

ryobi, 40-volt, brushless, ry40180


Three years ago, my Ryobi mower was among the first cordless electric mowers I had seen. Now, however, it seems that the cordless revolution has truly arrived. Battery operated mowers offer everything you like about mowing a lawn without all of the things you hate. No gas, oil, cords, or noise.

They are environmentally friendly and require none of the yearly maintenance that traditional mowers require. They start instantly with the press of a button, run much more quietly and, of course, do not emit exhaust fumes. Everyone I know who has made the switch has said that when they owned a gas mower they weren’t particularly offended by the noise and inconvenience of gas, however after switching, they couldn’t dream of going back.

ryobi, 40-volt, brushless, ry40180

The main advantages of the Ryobi mower are that:

  • It’s very lightweight and maneuverable
  • Its folding design makes it very portable and easy to hang
  • Its runtime is very long, amongs the best on the market
  • Its rechargeable lithium-ion batteries can be used to power your other compatible Ryobi cordless lawn equipment.


  • There is no option of a side discharge
  • It’s not self-propelled. Although it is lightweight, it may be difficult for some to maneuver on hills or steep grades. A self propelled version is now available, which I will hopefully get a chance to test
  • Its charge rate is good, however a ‘quick charge’ option would be good

Over a three year period, I’ve used this mower in wide range of conditions – super thick grass, wet grass, new sod, new seed, mulching leaves, bagging, different cut heights etc, and its power and performance did not disappoint.

It can handle tough grass without any issue, and given how light it is, it did well on newly seeded areas as well. When the mower hits a patch of lawn that is tougher it adds more power. You can hear the motor speed up to compensate. This is done automatically in order to conserve battery usage.

In my experience I get approximately 40 minutes from a full charge of one 4 amp hour battery. My lawn can usually be done in about 30 minutes, so I’m able to do it all with one battery. And that usually leaves enough juice left to do the trimming as well. Not that I need to use one battery for both. The mower and trimmer both came with 2 batteries, so I could easily do my neighbors lawns as well if I needed too. I bought the blower without batteries, when I realized how much extra capacity I had. I believe the current model of this mower now comes with a single 5.0 Ah battery.

ryobi, 40-volt, brushless, ry40180

Ryobi’s batteries charge to full capacity in 90 minutes. So technically, if you had three batteries, you could basically mow indefinitely. The batteries each have 4 led lights on them so you can check their power level and you can see their charge progress as they’re charging. Even though the mower could be used to mow 1/2 acre or larger; in my opinion, it is best suited for lawns that are between 1/3 of an acre to 1/2 an acre. That leaves you plenty of capacity for those days when the grass is super thick, or if you need to cut when it’s wet. And, truthfully, I think most people would want a self-propelled mower for lawns larger than 1/2 an acre.


Over my three years of ownership I only had two things break on the mower. The first item was the plastic battery cover. One of the hinge pins broke when I was opening it. It doesn’t open quite far enough in my opinion. I was able to fix this simply by putting a bent nail in it’s place. The other item that broke, was the rear protective shield. See photo. It basically ripped off. This item receives a lot of wear, so perhaps it should be made from metal instead of plastic and rubber. I called Ryobi about this problem and they mailed me a new one free of charge, so that wasn’t too big of a deal. It was fairly easy to swap out.

ryobi, 40-volt, brushless, ry40180


The starting price of the Ryobi is comparable to gas mowers, while also having comparable power. It cuts just as good as a gas mower. In fact, it is the same style blade. Similarly sized gas push gas mowers, however, weigh between 60 and 70 lbs. So the Ryobi pushes a bit easier than a push gas mower in my opinion. In comparison to other battery powered mowers, it’s main competitor is the more espensive EGO mower. The design of the Ryobi isn’t quite as refined as the EGO, however it offers a more appealing value proposition in my opinion. Other 36V cordless mowers look like reasonably good alternatives, but their power and feature sets just don’t compare.

In conclusion, I highly recommend this mower. Ryobi offers a great combination of features at a reasonable price. It’s perfect for a small to medium-sized lawns, and especially attractive if you plan to buy other tools that can use the 40-volt battery architecture. It’s very light, very portable, does an excellent job cutting, and has ample run time. On top of that, it has all the benefits of a cordless electric mower – ie. quiet, no maintenance, easy storage, easy to start, etc.

Комментарии и мнения владельцев

JC after 3 years…my only problem is that my “circuit” breaker keeps popping. I need to wait about 2 minutes to reset it. Any idea how to get this fixed?

Kevin Not sure. It should still be under warranty. If it can wait until winter you that’s a more convenient time to get repairs done

Joseph J Dear JC, I was also facing similar problem with my old Ryobi lawn mower. After a proper servicing by a local expert fixed the issue. So I suggest you to do the same.

Diane Romanski Hi I brought the newer Ryobi push lawn mower yesterday and after charging the battery to full capacity I mowed my yard. It was 88 degrees and hadn’t rained here in days. I noticed that my passes of cutting had grass that had never been cut. I am not understanding why this is happening. I tried googling it and it talked a lot about sharpening the blade. I just took it out of the box yesterday. Any ideas? Thank you.

Joe Anshien Let me say that there are some very good things about this mower but if you serch YouTube or other sites for problems they are there. Mine kept cutting out and I tried all the DIY solutions and eventually took the thing part. The inside had tons of grass clippings indicating it is sealed very poorly. Eventually I gave up and brought it to Home Depot for service. Even though it has a warranty they charge a 20 evaluation fee. Then they send it to Atlanta for repair. After about 6 weeks I finally got the # for the repair depot in Atlanta and called. They said they had not received it. I could have pushed to mower to Atlanta from Richmond in less than 6 weeks. At the end of this saga I fanally got it back after over 3 months and they tried charging me over 70 for stuff that I did not authorize such as that protective shield. I met a guy on the way out that heard me complain and said his trimmer was MIA for over 6 months. Better have a backup mower if this one ever needs service.

Summer Mowing: RYOBI 40V Brushless Mower

ryobi, 40-volt, brushless, ry40180

When our guests arrived at our house last weekend, they were very impressed. Our house was clean, but even more noticeable was our new, tidy, perfectly cut yard.

Mom does the mowing.

My husband and kids helped me clean the bathrooms, vacuum, get the outside entertaining area picked up, yard work done, pool cleaned, and I did the de-cluttering (a job for mom). Oh, and probably unlike most households, I did the mowing. It’s always been an outside chore that I love. I do the mowing here! There’s something about the satisfaction of how something so ragged, within a few minutes, can look so sharp and clean!

Yeah. This is how we roll when we’re hosting a bigger event or dinner party in our home. Our preparation is intentional, and usually involves a little more detail when a larger group is coming, because we want our guests to feel comfortable and welcomed in our space.

ryobi, 40-volt, brushless, ry40180

The cordless mower.

In steps our new RYOBI 40V Brushless (cordless) Mower. The lightest, powerful mower – ever!

Their new 40V mower has a 20” cutting deck (vs. their current 16”) and a brushless motor, powered by a 40V lithium-ion battery (two are included!)

When it arrived, my husband put it together in no time, putting on the handle, and then charging the batteries. That was it!

It only takes 90 minutes to recharge each battery. So easy to replace, and we can mow the front and back yard with 1 battery when the grass is dry. We have noticed that with wetter grass, we have to use both batteries, which makes sense, but even then it doesn’t drain all the way down.

ryobi, 40-volt, brushless, ry40180

Seriously, friends, mowing has never been easier. The instant-starting—you just hold the start button down for 3 seconds—is the coolest thing ever!

ryobi, 40-volt, brushless, ry40180

Love the easy removable light-weight bag. I dump our grass right into our compost bin. You can choose between two discharge functions, mulch or bag, for your grass trimmings.

It’s so quiet.

Another thing our family noticed is that, with this whisper quiet mower, we can get our yard work done nice and early and no one will hear us! It’s that quiet, that neighbors will not be bothered with the usually obnoxious mowing sound.

One more thing I was impressed by, as the family mower, was how light and airy it felt, and there was no exhaust! We can now store our lawn mower in the garage and not have to worry about any gas smell. For that matter, we don’t have to haul gas, stinking up our car each time we do. This thing saves time, your nose, ears, and takes up little space. It’s so light that it will save your back as well. And my husband no longer has to worry about keeping a mower’s gas engine working. This one is virtually maintenance free and, even better, uses the same battery pack that powers our other Ryobi outdoor tools, such as our trimmer and cultivator.

When you are done with your trimming task, use the quick release handle and collapse the unit for compact storage in your garage or shed.

Summer fun on the lawn.

I like being able to check off our “to do” list that the lawns have been mowed.

ryobi, 40-volt, brushless, ry40180

It doesn’t take much time for the backyard to be ready and our family to be prepared, as our guests arrive. Which, by the way, it’s ready for crochet, bad minton, swimming … all kinds of summer fun!

Who does the mowing in your family? Are you happy with your mower?

By taking advantage of the current cordless battery technology, manufacturers are producing mowers that are powerful and fully capable of maintaining an average sized property. The Ryobi 40V 21 In. Brushless Smart Trek Self-Propelled Mower offering is packed with features as well as impressive power, minus the pull cord, gas and oil.

Ryobi Smart TREK Self-Propelled Mower

The Ryobi 40V 21 In. Brushless Smart Trek Self-Propelled Mower is the latest offering in their Lawn Garden line of outdoor power equipment. This mower features new technology such as their Smart TREK self-propel system which automatically adjusts to the pace of the user.

The unit is powered by a massive 40 Volt 6.0 AH battery that provides what Ryobi describes as “gas like power” and up to a half acre worth of run time. This battery is currently only available with the mower. information and technical specifications on this mower are available at the Ryobi website.

ryobi, 40-volt, brushless, ry40180

21″ Cutting Capacity

This mower is the largest in the Ryobi cordless mower series with the largest cutting capacity at 21”. The steel deck is a stamped/non-fabricated construction and is on par with any similar gas powered mower. The steel deck offers better durability and enhanced safety for the user.

Deck Height Adjustment

Adjusting the height of the blade deck is simple and intuitive using a handle on the top of the deck with a trigger mechanism. Simply pull the trigger and push down or pull up in the direction of the clearly marked height settings. After releasing the trigger the deck will lock into place using one of the 7 factory detent settings.

EASY Tilt and Lift Bag Attachment

The Ryobi also includes a bagger attachment that can be emptied with one hand in a “tilt and lift” motion. If you prefer to mulch your clippings a plug kit is provided for the rear bagger opening. This plug kit is easy to install, but I found that it frequently became packed with grass clippings and had to be cleaned out.

Ryobi 6.0 Ah Battery Powers the Smart TREK Mower

Ryobi had to step up their battery offerings in order to provide constant and uninterrupted power for this new larger mower. Their new 6.0 AH battery is simply a beast! It is about the same size as a Belgian block paver and just as ergonomic. The battery weighs approximately 4 pounds and has a push button green LED charge level gauge.

Ryobi Compact Slide On Charger

Ryobi included a compact slide on style charger that also doubles as a portable power station. The charger clips onto the battery for charging but also has a power port for a USB cable. When used as a power station the charger will produce 2.1 Amps of output. A great option for charging electronic devices during a power outage or camping or other outdoor activities.

The battery compartment for the mower is located on the top of the main drive housing. There is a spring loaded translucent plastic lid that covers the battery compartment. This lid has a waterproof seal as well. Inside is an attachment point for the battery as well as a spare battery holder and a red plastic master safety key.


The best part of this mower is the complete lack of excessive noise, gas and oil. The thing sounds like a warp drive engaging when it starts up! The brushless motor is smooth and powerful and the entire design is compact and less bulky than traditional mowers.

Folds For Storage

I can fold the Ryobi up with the push bar folded down and store the unit upright in my garage to save space. Plus I never have to worry about spilling gas or oil when doing this. The only maintenance requirements for general use are sharpening the blades, charging the battery, and cleaning off the deck.

Smart TREK Self-propel System – Needs Improvement

Smart TREK self-propel system that is advertised as one of the biggest features ended up being an issue for me. The Smart TREK system engages when pushing down on the telescoping control handle during use. The system then speeds up or slows down based upon the downward pressure of the user. This system worked well on flat and even terrain, but seemed to stall out completely for me when used on slightly uneven terrain. I ended up wrestling the mower the same as I would with a traditional push mower.
