Greenworks 21-Inch 40v Brushless Cordless Mower Review

The Greenworks 40V Mower is a 21 inch, self-propelled electric lawnmower. According to the manufacturer, it is ideal for plots up to half an acre in size. As long as you are a residential property owner, you’ll notice that the performance of this mower is, in many ways, comparable to that of a gas mower. In fact, the Greenworks actually has a couple of unique tricks up its sleeve to make life even easier.

There are two configurations that you can opt for:

In this review, we will talk about the 6AH battery version. Please note that the charger is also included in the box.

A few years back, electric mowers used to be just an inferior version of their gas-powered cousins.

However, they have evolved into very competent machines and today, they trump gas-powered mowers on many fronts. First of all, they are more environmentally friendly. The motor has a longer life since it undergoes less wear and tear.

They generate instantaneous torque and reach maximum power in just 3-4 seconds. You do not have to worry about topping them up with fuel and yes, no more trips to the station if you run out of gas while mowing your lawn!

In a bid to control air pollution levels, many urban areas are considering restrictions on the use of gas-powered mowers (they might get classified as farming equipment). This makes electric mowers even more relevant for residential property owners.

The Greenworks 40V is a cordless mower and hence, it does not need to be connected to a power source all the time.

You can mow the far end of the lawn without worrying about extension cords and stuff! We really like this mower for small to medium-sized plots. Let’s check out some its features in further detail.

Greenworks 40V Mower Features:

40 Minutes of Mowing Time:

The mower delivers 40 minutes of mowing time on a single charge. Depending upon the size of your yard, you could mow it more than once before having to charge it again.

If you opt for a second, auxiliary battery, you can use one while the other is being charged. This totally depends on your requirements.

Greenworks has a number of other cool and useful tools that run on the same battery, so it might be worth considering.

21 Inch Steel Deck:

The steel deck is hardy and reliable. We don’t think it will be easily damaged unless you plan to use it on uneven land covered with large rocks and such.

Since this is a purely residential mower, a steel deck is more than sufficient. Almost all mowers have steel decks.

Only some heavy-duty commercial-grade mowers have Nexite decks (those come with a lifetime warranty).

Push Button Start:

The Greenworks 40V starts in a couple of seconds thanks to a convenient push start button. No more yanking on cords for a dozen times to get the damn mower started (some older gas powered models have that kind of a starter mechanism).

This is such a hassle-free mower in so many ways. It does not produce any sort of loud unpleasant noises. Even if you’re a petrol-head, there’s no way you enjoy the sound and fumes of a gas powered mower on a pleasant Sunday morning!

Vertical Storage:

As we said, this is a very convenient machine. It can be stored vertically and hence it requires way less, up to 70% less, storage space.

Now, residential properties usually do not feature oversized barns – they have smallish sheds and hence, vertical storage is a real blessing as in the city, space comes at a very high premium!

SmartCut Technology:

The power is adjusted automatically depending upon the length of the grass. If the grass is long and thick, then the machine draws more power but if it’s short, then it uses only as much power as is required and conserves the rest.

This results in a clean cut without compromising on battery life.

Brushless Motor:

Conventional motors have a brush mechanism that puts the energy into motion. Electric motors have a magnetic field for the same purpose.

The brush undergoes a lot of wear and tear and is prone to damage. Electric motors have no such weakness. Yes, the circuit board is probably a weak link but it usually has better longevity compared to the brush.

Hence, brushless motors require less maintenance and can last for a really long time.

Also, they are less noisy compared to a gas-powered motor. Hence, you can mow the lawn without creating a ruckus and waking up the kids and the neighbors. Your shoulders and arms will love the fewer vibrations of a brushless motor. Go about your job without experience fatigue.

Lithium-Ion Battery:

The batteries deliver a formidable amount of power on a single charge. There’s a battery life indicator on board and most importantly, the battery comes with a very thoughtful USB port for charging devices such as a mobile phone etc.

The same battery can be used for over 50 tools from the Greenworks range.

3-in-1:

The Greenworks 40 V gives you the option to mulch, bag or side-discharge. Some plot owners prefer to mulch once in a while to prevent the soil from drying and to ensure that it gets enough nutrients.

Side discharge is a very useful addition too. We’ve noticed that this option is unavailable even on some premium models. We have to laud Greenworks for the versatility of this mower.

Greenworks 40V Mower Review Final Verdict:

The Greenworks 40 V is a very good lawnmower for small to medium plots. If you’re looking for longer runtime, we recommend that you consider the Greenworks 80V, which is suitable for plots up to 1 acre.

Assembly was an ease, charged battery full before first mowing. I have a small lawn, 0.2 Acre plot w house. Can mow entire lawn w 1/4 charge. 2nd Greenworks product. 1st was the 16” chainsaw. Both products work great. Like the mower w metal mower body vs plastic. 3 mowing sessions and still impressed. Looking forward to expanding w more greenworks products that fit the 40V 4Ah battery.

Most helpful negative review

I have used this lawn mower 3 times now. The battery only last about 20 minutes or so. The cut quality is poor. It misses allot of blades of grass even if I go over it twice. I don’t reccommend this mower. Sorry. I wanted to give it a good review but I have to be honest. I would like to send it back for a refund.

This is the best mower I’ve ever owned. It is lightweight. It cuts beautifully. 7 different cutting levels. The bag is easy to empty. I was able to mow for an hour and still had battery life.

Extremely disappointed. i bought this last year. only used a couple of times (not mùch grass). Put away for winter. Just pulled it out and it isnt working at all. This is the 2nd big item I bought from Walmart that was defective. Battery charges but nothing happens. Really getting fed up with Walmart. Either they’re out of stock or broken or defective. Been a loyal customer for 30 years. Company has really gone down hill.

Like the mower. Solid, well-made. Cuts well. Small grass catcher, but don’t plan to use it every time. Only downside is the battery cut out 1/2 way thru the backyard (after finishing the front). NOT a big yard, run time was about 25-30 minutes tops. Bought a second battery, will try switching out and see if that solves anything.

Grass bag, side discharge or mulching. 1 lever to adjust cut height. Easy start. Easy assembly. Haven’t used it yet because you need green, growing grass.- too early in Montana. But started up and sounded good in garage. Seems to be a solid, well-built machine. Looking forward to putting it to use. Have a Greenworks snowblower and been using it for 3 or 4 seasons now. If the mower works as well, will be very satisfied.

Was delivered on day expected. Just love the product mows better than expected. very easy to use. No more trips for gas or pull cords for me. I’m 72 and more independent now i can mow my own yard. Love it.

Ok, I came from having a plug in sun joe so its amazing. 7 different cutting heights, so easy. Charged for two hours and it used half the battery approximately.

Mower arrived yesterday. Fast shipping. Read the enclosed booklet. Attached handle as instructed. Plugged in charger and attached battery and the diagnostic charger glowed a solid red (for the battery charging). Reviewed instructions-that solid red is not listed. Repeated several times and same result so charger is obviously not diagnosing as advertised. Put battery in mower and it started ?! Left off charger then as it was obviously charged to some degree but that was never indicated by the light colors. Mowed a few minutes today and battery has obviously run down so is on charger again. If this is how this is gonna’ work, it’s more than a little frustrating. On low blade height which is what I bought it for to eliminate thatch from building in my lawn, it won’t cut but cuts off. Frustrating there too. Would I purchase again? Not sure.

Stopped working after the 7th time. Comes with warranty but minimum you get charged for repair is 50. Don’t buy Greenworks.

Worx 40V Cordless Mower vs. Greenworks 40V Cordless Mower: Which One Wins?

A manicured lawn is key to increasing your property’s curb appeal. While there are many ways to cut grass, a cordless lawnmower is your best bet. This tool is quieter than its gas-powered counterpart and comes with no strings – aka a power cord – attached. Not to mention that battery-powered tools are also eco-friendly, so you won’t contribute to carb emissions and the greenhouse effect.

As you’d expect, numerous brands propose their own versions of cordless mowers. Some are simple, while others come with all the bells and whistles, but if you want a capable mower that won’t break the bank, your choices often come down to Worx and Greenworks.

If you don’t know which to pick, this comparison between the Worx 40V cordless mower and the Greenworks 40V cordless mower might help you decide.

Worx 40V Cordless Mower vs. Greenworks 40V Cordless Mower: What’s the Difference?

Greenworks and Worx’s 40V mower lineups include a range of push-behind and self-propelled mowers. Tools in both lines are designed for lawns of about the same size. Plus, they have similar and performance capabilities. However, subtle differences do exist, and they could make you prefer a specific model over the others.

Let’s see how these two mowers compare.

Performance

Cordless lawnmowers have been frowned upon for a long time due to their poor performance, but that’s no longer the case. Today, even residential-grade battery-powered tools can deliver gas-like power, but you must still consider things like cutting height, cutting height adjustments, and cutting swath when choosing the right mower for you.

Worx offers its 40V cordless mower in four sizes, from 14 to 21 inches. However, keep in mind that the specified size refers to the actual size of the cutting deck, not the cutting swath.

In fact, the cutting swath is one inch smaller, which basically translates to more passes to mow the entire surface. Likewise, the Greenworks 40V mowers come in six sizes between 14 and 21 inches, but the actual cutting swath can be up to 1.25 inches smaller than the specified deck size.

In the Worx 40V mowers, the cutting heights vary from 1.16 to 4 inches, depending on the model. This generous range makes these cordless mowers ideal for all kinds of turfs, including warm and cool-season varieties. Greenworks offers a cutting range from 1.375 to 3.75 inches, which is still great for most grasses, but less ideal for some ornamental turfs such as Zoysia, Creeping Bentgrass, or Colonial Bentgrass, which should be cut shorter than 1.375 inches during the growing season.

Both brands offer their mower with five to seven cutting height adjustments, depending on the model. Smaller, push-behind models typically have fewer settings than the larger or self-propelled variants.

As far as cutting performance is concerned, some Greenworks models feature a dual-blade deck designed to improve efficiency. Worx boasts Auto-IntelliCut™ technology that adjusts power based on turf conditions. Basically, this function helps prevent ripping the grass blades and saves energy on patches that don’t require a high cutting power.

Battery and Runtime

While the 40V mowers from both Worx and Greenworks have the same nominal voltage, a difference in the battery pack wins Worx a victory. This brand equips its 40V mowers with two 20V batteries. The mowers can’t run on one battery alone, but each battery brings up to 35 minutes of runtime. Combined, you can get up to 70 minutes of uninterrupted mowing per charge.

The Greenworks 40V mowers use a single 40V battery. This battery delivers a maximum runtime of 45 minutes, depending on the actual amount of energy charged or amp hours (Ah).

Greenworks offers a range of batteries for its 40V mowers, from 2.0 Ah to 5.0 Ah. Worx’s 20V batteries feature the same capacities, but most of its 40V cordless mowers use 4.0 Ah or 5.0 Ah batteries. Since higher amp hours mean a longer runtime, the use of higher-capacity batteries gives Worx an advantage.

However, the high amp hours also come with a drawback — these batteries take longer to charge. Regardless of the actual capacity, Greenworks wins this round with its fast-charging systems. The brand’s 2.0Ah batteries are the fastest to charge, in about half an hour. A 4.0 Ah battery can be fully charged in around 60 minutes, which is a lot faster compared to Worx. In fact, the Worx 4.0 Ah batteries require about 125 minutes to be fully charged with a fast charger. With a standard charger, the time goes up to around four hours.

On the bright side, both brands equip their mowers with interchangeable batteries within their respective ecosystems. Hence, you can use batteries from compatible tools to extend the runtime.

Waste Management

Dealing with grass clippings can be a hassle, but most cordless mowers allow you to choose between mulching, bagging, or side discharging. The same is true for the Worx 40V and the Greenworks 40V mowers, even though the entry-level models from both brands only offer mulching and rear bagging. Side discharging is available on the higher-end options, including the self-propelled models.

Maneuverability

Both Worx and Greenworks offer their 40V mowers in push-behind and self-propelled models. As you can imagine, the push-behind mowers rely on your pushing power for propulsion, and the tool’s overall weight plays a direct role in maneuverability.

Lighter mowers are obviously easier to push across the lawn and turn around obstacles. However, heavier decks cut grass better. So, when choosing a push mower, it’s all about finding the right balance between weight and maneuverability.

Worx manages to find a better balance than Greenworks. For instance, the Worx 40V 14-inch mower weighs 29.1 pounds (without batteries). That’s light enough to push across the lawn but heavy enough to deliver great cuts. The Greenworks 40V 14-inch mower weighs 33 pounds. It is obviously heavy enough to ensure clean cuts but somewhat more challenging to push around.

Price

Worx and Greenworks manufacture similarly priced mowers, but there are some slight differences. The former is cheaper if you want a capable entry-level model, which you can get for around 180 from Worx. A similar mower from Greenworks can set you back around 230.

Things change for the high-end options. You can expect to spend about 530 on a self-propelled 21-inch mower from Greenworks, but a Worx 40V 21-inch self-propelled mower costs around 550. These price differences are not excessive, so it’s up to you to decide whether the Auto-IntelliCut™ technology is worth the extra premium.
