Best Electric Corded and Cordless Walk-Behind Lawn Mowers

Electric walk-behind lawn mowers are the most common type of lawn mowers found in backyard gardens.

They are easy to use, safe to operate when used properly, relatively cheap, and can last for a long time with minimum maintenance and care, etc. However, when buying one, there are a few things to consider.

The main advantages of electric lawn mowers, when compared with gas-operated units are lower noise, easier maintenance, no smelly gases, zero CO2 emission, and similar. More than enough reasons to choose an electric lawn mower over a gas lawn mower for your backyard garden.

Corded vs. Cordless Electric Lawn Mowers

Electric lawn mowers can be corded or cordless. Corded electric lawn movers use mains power as a power source and require a long electric power cord to be pulled behind.

Cordless electric lawn mowers use the energy stored in the onboard batteries. Their main advantage is that there are no cords to pull around, and they don't depend on the availability of an electric grid and mains power.

However, operating time is limited by the capacity of the battery, and it ranges from 20 to 60 minutes or even more on a single battery charge.

The main advantages and disadvantages of corded electric mowers vs. cordless lawn mowers are:

- price: corded electric lawn mowers are cheaper than cordless lawn mowers. Cordless lawn mowers usually operate using expensive but light and powerful lithium-ion batteries.

Such batteries require dedicated chargers, have very low discharge rate, "fade-free" power output, can be charged quickly (30 or so minutes, sometimes even faster than that), store huge amounts of energy per weight of battery, when treated properly, can be charged and discharged 500+ times, etc.

But again, they are expensive. The good thing about these batteries is that they are often standardized - each manufacturer has "standard" types of batteries for power tools, including cordless lawn mowers.

So, if you have power tools from one manufacturer, including a set of lithium batteries, and you need a cordless lawn mower, consider such a unit from that manufacturer first. Savings can be quite large - sometimes even hundreds of dollars/euros.

- covered area - cordless lawn mowers can cover a limited area, depending on the battery capacity, the number of batteries, and similar.

Corded lawn mowers' area depends on the length of the extension cord - a long extension cord is much cheaper than a set of new batteries. However, if you do need a lawn mower for your garden and patio only, and a cordless unit can cover it, consider cordless units, too.

Having a pack of two high-capacity lithium batteries can be very helpful since one battery can be used in lawn mower, while the second battery is being charged.

Depending on the capacity and type of terrain and grass, such batteries can provide zero lawn mower "downtime".

Nonetheless, if you do operate two batteries that way, it is highly recommended to let the batteries cool down a little bit after being fully charged - after all, before using them, read the manual thoroughly.

Batteries are often replaced quickly and easily, within seconds. If they are operated on heavy terrain, be careful, they can be quite warm, even hot. Although lithium batteries come with all sorts of safety features (over-current protection, over-charge or over-discharge protection, high-temperature protection, and similar), treat them carefully and, if required, let them cool down - they will last longer.

To extend the operating time, cordless lawn mowers are often equipped with 'smart' motor controllers - they adjust the strength and hence the power drawn from the batteries according to the terrain and grass, prolonging the operating time on a single charge without sacrificing performance.

extension cord- ease of use - corded units pull extension cords behind or aside from lawn mowers. One must be aware of the cord position all the time, or a high-speed rotating steel blade can catch the cable, make a short-circuit and slice the cable.

Note: Trust me, it is not fun when something like that happens - 110V (US) or 220V (EU) can be dangerous, even if you have fast, automatic circuit breakers.

When choosing an extension cord for your corded lawn mower, be sure that it is not green (yellow, orange, and similar bright colors are highly recommended) and that cable is thick enough - if you have 12 Amps lawn mower, go for a 16A or thicker extension cord, especially if it is longer than 50-75 feet (15 - 23m).

Note that most of the corded lawn mowers don't come with an extension cord, and it has to be purchased separately.

When using a cordless lawn mower, forget the extension cord and enjoy your work :)

- control systems - most corded units just have a power handle to turn the lawn mower on and off, while cordless units usually have a power handle and indicator lights (or even small speakers) for battery charge status, battery temperature, and similar.

- maintenance - maintenance of corded and cordless lawn mowers is very similar. The differences are the extension cord (when worn out, buy another cable, cheap) and the batteries (when capacity decreases, buy another battery - it can be quite costly).

Other maintenance jobs like keeping the blade(s) sharp or lubricating the moving parts are essentially the same - just be sure to check the manual before using your lawn mower.

Electric lawn mower, cordless or corded? Well, I like my corded lawn mower, and I hope it will last for years to come. I am used to corded units, so it will take some time before I consider cordless units.

However, my kids are growing up, and I will rather let them use a cordless unit due to the absence of the cord. So, at the moment - corded electric lawn mowers, but in the long run, cordless ones.

Other Electric Lawn Mower Features

Number and width of the blades - one of the most common specifications is the cutting/mowing width, which is given in inches (US) or centimeters (EU).

Lawn mowers usually have one single blade, and it's length defines the width of the mowing. Common blade size for small gardens is between 14 inches (~36 cm) and 21 inches (~53 cm).

A larger blade cuts more grass in one single pass, but it also increases the size, weight, and footprint of the lawn mower, decreasing maneuverability and requiring a stronger motor and more area for storage.

To achieve larger mowing width, some models have two motors and two blades positioned side-by-side and slightly behind one another. This way, mowing width is increased without increasing the size of the mower, at the expense of having two blades and two motors.

corded lawn mower 1Height adjustment system - in order to mow the grass at the desired height, lawn mowers have some sort of "height adjustment system."

The simplest one is in the form of 3-4 holes for wheels' axles - in order to change the height, one has to unscrew the wheel axle first from the current position and then screw the axle in the required hole to achieve desired mowing height.

This is a very simple and very durable system - just set the desired height once you buy your mower and forget about it :)

More expensive models of lawn mowers have a special handle for quick and simple mowing height adjustment - such a system increases the price and mechanical complexity, but if you have to change mowing height often, it is simply a must-have feature.

A grass catcher is a plastic or rubber, rigid, semi-rigid, or fully flexible bag at the end of the mower's body. As the blades spin, they cut the grass and create the airflow that carries it into the bag for easy disposal.

Such grass is an excellent material for mulching or for making homemade compost. Some lawn mowers even come with an additional impeller, which creates even stronger airflow for better grass removal and for additional slicing of the grass blades - important for keeping the lawn clean and for mulching and composting but adds to mechanical complexity and price.

cordless lawn mower 3 storageUnit storage - in order to occupy as less storage space as possible, most lawn mowers can be folded and stored upwards. Such a position requires very little space and can come in very handy when storage space is limited.

Personally, I don't like storing heavy objects vertically because they can easily fall over - people with little kids and pets know what I am talking about.

Lawn mowers can come with several safety systems, but one of the most important is an automatic shut-off system when the power handle is released. When the power handle is released, the motor is turned off, and the automatic brake quickly slows down and stops the spinning blade.

If your blade continues to spin for more than 1-2 seconds after the handle is released, check the manual and, if required, take the lawn mower to the service center.

Other safety systems include, if present: motor and battery temperature check (switch the motor off to prevent overheating), motor speed and Amps check (to detect jammed axles and blades), and similar.

All those systems add to the complexity and the price of the unit, so don't expect them in cheaper models.

Most Popular Corded Electric Lawn Mowers

Here is our list of the best, most popular corded electric lawn mowers:

Greenworks 25142 16-Inch 10 Amp Corded Electric Lawn Mower

Greenworks 25142 16-Inch 10 Amp Corded Electric Lawn Mower is a very popular, compact walk-behind, corded lawn mower.

It is a well balanced 2-in-1 lawn mower, designed for small yards, combining a plastic but tough 16" cutting deck with 10 Amps motor.

greenworks 25142 1

Assembled Greenworks 25142 weighs only 39 pounds (~17.7 kg), with the weight distributed over 6-inch (~15.2 cm) front and 7-inch (17.8 cm) rear wheels.

Unit is designed with 2-in-1 functionality in mind - it may be used for mulching or for collecting the grass clipping.

Many similar units feature the third option - side mulching - but Greenworks 25142 doesn't.

This means that the 16-inch (~41 cm) cutting deck is more robust and durable, leading to a longer warranty period. Greenworks 25142 comes with a 4-year limited warranty, which is a very good warranty for the unit in its class.

greenworks 25142 height lever

Cutting height is changed using a single height adjustment lever on the left side of the mower - there is a total of 5 positions, ranging from 5/8" to 2 5/8" (1.7 - 6.7 cm).

Greenworks 25142 is rated at 10 Amps, which is more than enough for a 16" sharp blade to make clean cuts even in tough grass.

No load speed of the blade is ~3800 rpm.

Greenworks 25142 comes with a short pig-tail power cord and safety bail switch, which instantly turns off the unit when released.

For outdoor use, brightly colored extension cords are recommended in a suitable size.

Since Greenworks 25142 is rated at 10 Amps, just to be sure, consider getting 12 Amps extensions cord intended for outdoor use, labeled as Type SW–A, SOW–A, STW–A, STOW–A, SJW–A, SJOW–A, SJTW–A, SJTOW–A, or similar.

Note: although there are brightly colored green extension cords, green color is not recommended for lawns. IMHO, of course. Brightly colored yellow, red, orange, or even light blue should be preferred colors for lawn mower extension cords.

Depending on the cable length, it is recommended to use the following:

- 50 feet (~15 m): 16 AWG,

- 100 feet (~30m): 14 AWG,

- 150 feet (~45m): 12 AWG.

Thin cords cause a loss of power and may overheat, while thicker cords may be hard to work with.

greenworks 25142 2

In order to help with the storage, the handle may be folded, saving storage space.

Note: Greenworks 25142 is easy to use and maintain lawn mower, but when it arrives, just in case, be sure to read the manual thoroughly to get accustomed to your new lawn mower.

Long Story Short: If you are looking for a lightweight, compact, but strong, and durable lawn mower designed for smaller yards, consider Greenworks 25142.

It is a very maneuverable lawn mower, being able to mow near the walls, around the trees, at slopes, and similar.

Note: when mowing the slopes, never mow up and down, but along the slopes - recommendations about mowing the slopes are given in the manual in great detail, so please, be sure to read it.

sun joe mj401e pro 1

When assembled and ready for use, Sun Joe MJ401E-PRO corded lawn mower features physical dimensions of (L x W x H) 48.4 x 16.1 x 40.6 inches (~123 x 41 x 103 cm), and it weighs only 30 pounds (~13.6 kg), ensuring good maneuverability even in tight places.

Unit is rated at 13 Amps, which in combination with a 14-inch (~35.6 cm) wide blade, ensures clean and even cuts.

The no-load speed of the blade is 3500 RPM.

Note: Sun Joe MJ401E-PRO features a plastic cutting deck and in order to make the deck as rigid and durable as possible, it has only a rear opening for grass clippings, which is used for collecting the grass clippings in the grass bag or for side discharge via a side discharge chute. This makes also Sun Joe MJ401E-PRO a compact, lightweight, and affordable unit that comes with a 2-year warranty, which is excellent in this price class.

side discharge

Thanks to its weight, Sun Joe MJ401E-PRO also features a carrying handle allowing the user to easily carry it when required. In combination with a collapsible handle, Sun Joe MJ401E-PRO doesn't require much space for storage, when not in use.

Note: Sun Joe MJ401E-PRO is a very simple-to-use and maintain corded, walk-behind lawn mower. Nonetheless, when it arrives, be sure to thoroughly read the Owner's Guide/manual in order to get accustomed to your new lawn mower.

Sun Joe MJ401E-PRO lawn mower comes with a 1-ft (~0.3 m) pigtail power cord, requiring the user to have one of the required length and thickness.

Since Sun Joe MJ401E-PRO is rated at 13 Amps, the extension cord should be rated at least for 15 Amps. Also, the extension cord should not be longer than 100 feet (~30.5 m).

Thicker extension cords can be used, of course, in order to decrease the energy losses in the cord, but thicker cables are more difficult to work with.

Also, since the extension cord will be used for mowing the lawn, it should have bright yellow, orange, red or similar colors - in any case, it should not be dark green in color, because such an extension cord may be difficult to spot in the grass.

And no, running the lawn mower with a fast-spinning blade over the power cord is not the smartest thing to do ...

Long Story Short: If You are looking for a simple, affordable, but also reliable and reasonable, sturdy and durable corded, walk-behind lawn mower suitable for smaller and medium lawns, consider Sun Joe MJ401E-PRO lawn mower.

It is rated at 13 Amps and powers 14 inches blade, provides clean and even cuts, is simple to use and maintain, etc. Also, its height adjustment system requires users to flip up the lawn mower and adjust the height of each wheel, but that is the price of simplicity, which is often the key to durability.

American Lawn Mower Company 50514 Corded Electric Lawn Mower

Walk-behind lawn mower Model 50514, manufactured by American Lawn Mower Company, is a compact and lightweight corded electric lawn mower.

It features a 14-inch cutting width, combined with an 11-Amps electric motor in a durable and reliable, very popular lawn mower.

American Lawn Mower Company 50514 Corded Electric Lawn Mower is designed for small to medium size yards, featuring 2 common functions - rear discharge and mulching.

amrican lmc 50514 1

Model 50514 features 14 inches (~35.6 cm) cutting path and is powered with a very efficient 11 Amps electric motor, providing plenty of strength for a relatively narrow cutting path.

The unit is rather compact, allowing it to mow the grass where larger mowers can't reach or have access issues in general.

The physical dimensions of the Model 50514 are (L x W x H) 52 x 15 x 39 inches (~132 x 38.1 x 99 cm), and it weighs just 21 pounds (~9.5 kg).

The handle is adjustable, allowing the user to set the handle to the most comfortable position. The handle is made of steel, but the deck is made of plastic.

Many people consider plastic lawn mower decks to be weaker and not as durable as steel decks, but the Model 50514 deck is made of durable ABS plastic, and considering the size, weight, blade length, motor power, etc., it is the proper material for such lawn mower.

After all, this is one of the most popular lawn mowers for small and medium yards, tested in countless situations by many users, and the lawn mower performed and still performs very well!

amrican lmc 50514 2

When it arrives, American Lawn Mower Company Model 50514 must be assembled, which can be done rather quickly.

Note: Model 50514 is simple to use and maintain electric lawn mower, but when it arrives, just in case, read the manual thoroughly.

The unit features a "standard" start button, combined with a blade control lever as a safety feature.

Wheels are made of plastic and are large and wide enough to allow the user to maneuver easily with the mower and to leave no marks on the lawn.

Front wheels are 6 inches (~15.2 cm), and rear wheels are 8 inches (~20.3 cm) in diameter.

amrican lmc 50514 3Height is adjustable using a single lever - there are 5 cutting heights between 1 inch (~2.5 cm) and 2.5 inches (~6.4 cm). As one can see, Model 50515 is designed for shorter grass that must/should be kept neat and clean-cut.

However, many users reported that Model 50514 did an excellent job cutting tall, tough grass - users just had to mow slowly in a push-pull pattern.

Note: if you have to cut really tall grass with this or any similar lawn mower, set the cutting height to maximum, mow the lawn, and if possible, let the grass rest a few days (a week would be nice) and only then mow to the desired final height.

After that, cut whenever you please and in the period of the grass' strongest growth, that means, on average, once a week.

American Lawn Mower Company Model 50514 lawn mower features a large, 16 gal grass catcher bag. The top of the bag is hard plastic with a carrying handle, making it easy to attach, detach and carry a full or empty grass bag.

Also, the grass bag features a grass level indicator to let the user know the amount of grass clippings in the bag.

American Lawn Mower Company Model 50514 lawn mower, like many other similar electric lawn mowers, doesn't come with the extension cord by default, and it is up to the end user to have/get one.

When looking for a proper extension cord, remember a few notes:

- Model 50514 draws 11-Amps max during operation, and recommended extension cord should support at least 15 Amps. Personally, extension cords designed for currents up to 12 Amps (which is more than 11 Amps, of course), are too close to the unit's 11 Amps.

- go for the brightly colored extension cord that is easily visible in the grass.

- cord should be long enough to allow the user to mow the entire yard but not too long to make it hard to work with.

- last but not least, the extension cord should be in good condition.

The good outdoor extension cord must be labeled SW-A, SOW-A, STW-A, STOW-A, SJW-A, SJTW-A, or SJTOWA. If you don't own a proper extension cord, order one from online shops (or get one from a local hardware store), having these tips on your mind!

American Lawn Mower Company Model 50514 comes with a 2-year limited warranty, which is a very good warranty for the unit in this class.

Long Story Short: Model 50514 electric, a walk-behind lawn mower is a very popular and affordable tool that will help you keep your small and medium size yard in perfect condition.

The compact and lightweight design enables Model 50514 to reach and mow slopes and surfaces that are pretty much unreachable to larger mowers.

Nonetheless, when mowing, always be aware of your environment and be careful - a 14-inch blade spins fast, and cuts the grass evenly, but it can also cause damage and cause injuries.

Of course, there are many other corded electric lawn mowers on the market that are very popular for many reasons.

Ego Power+ 21" 56V LM2100SP Self-Propelled Cordless Lawn Mower

Ego Power+ LM2100SP is a cordless lawn mower powered by 56 volts Ego Power+ lithium-ion batteries, providing high-torque and long operating time on a single battery charge. 21-inch wide cutting deck and self-propelled feature help the user to cover more ground quickly, saving time and effort.

Although Ego Power+ LM2100SP may be powered by any Ego Power+ 56 volts battery, a large 7.5 Ah battery is highly recommended in combination with the rapid charger. Also, all other Ego Power+ tools may be powered by this or any other Ego Power+ batteries, providing great operational flexibility and decreasing costs in the long run.

ego lm2100sp 1

Ego Power+ LM2100SP is designed as a 3-in-1, walk-behind lawn mower and is powered by an onboard lithium-ion battery.

Recommended battery size is a 7.5 Ah battery, which is able to store an impressive 420 Wh of energy and is able to power Ego Power+ LM2100SP for a long time - operating time on the single battery charge depends on many things, more on that later.

Also, Ego Power+ BA4200 is a 56V 7.5 Ah lithium-ion battery that features a battery management system that protects the battery from damage due to heat, overcharging, over-discharging and similar. Best of all, even such a high-capacity battery may be fully charged in 60 minutes using Ego Power+ rapid charger or in 145 minutes using Ego Power+ standard battery charger.

ba4200 battery

Ego Power+ BA4200 weighs 6.31 pounds (2.86 kg) and comes with a 3-year limited warranty, while Ego Power+ LM2100SP lawn mower comes with a 5-year limited warranty.

When being powered by a 7.5 Ah battery, the operating time of the Ego Power+ LM2100SP on the single battery charge is:

- light load: 60+ minutes,

- medium load: 45 minutes,

- heavy load: 30 minutes.

Actual operating time depends on many conditions like the density of the grass, species, moisture if the self-propelled drive system is engaged or not, etc.

As a 3-in-1 lawn mower, Ego Power+ LM2100SP features side discharge of grass clippings, can be used for mulching, or it can store grass clippings in the large grass collector bag, which features a capacity of 70 liters.

Despite having 21 inches (~53.3 cm) cutting deck, Ego Power+ LM2100SP is a relatively lightweight unit weighing 62.61 pounds (28.4 kg) without a battery pack and ~69 pounds (~31.2 kg) with a 7.5 Ah battery.

ego lm2100sp controls

Controls of the unit are rather simple and easily accessible by the user.

The self-propelled feature drain the unit faster, but it may be very helpful during mowing, especially on uneven terrain (be very careful when mowing on such terrain or on the slopes!) and when mowing is done by elderly people.

The self-propelled feature is not mandatory, and many users operate Ego Power+ LM2100SP like an ordinary lawn mower and use the self-propelled feature before and after actually moving when it is time to store the unit.

When the self-propelled feature is used, speed varies between 1.8 and 3.6 mph (~2.9 and 5.8 km/h).

Note: Engaging a lawn mower blade does not automatically start the self-propelled feature, and vice versa, starting the self-propelled feature does not automatically start the mowing blade - these are two independent systems! Ego Power+ LM2100SP is a relatively simple unit to assemble, use and maintain, just be sure to thoroughly read the manual that comes with the unit.

The front wheels of the Ego Power+ LM2100SP are 7 inches (~17.8 cm) in diameter, and the rear wheels are 9 inches (~22.9 cm) in diameter, ensuring good maneuverability on flat terrain. Self-propelled drive engages only the rear wheels - it is not 4x4 drive (most of the self-propelled walk-behind lawn mowers feature drive on the rear axle only).

Note: Ego manufactures two very similar cordless lawn mowers, Ego Power+ LM2100SP (reviewed in this article) and Ego Power+ LM2100 - the main difference between these models is that Ego Power+ LM2100SP is a self-propelled lawn mower while Ego Power+ LM2100 is not self-propelled.

ego lm2100sp heigth adjustment

For operations in low-light conditions, Ego Power+ LM2100SP comes with a pair of strong LED headlights, helping the user to see what is ahead of the unit - just be very careful when mowing in such conditions due to the low visibility in general.

LED headlights are a questionable feature on home lawn mowers since mowing in low light conditions is not the safest thing to do.

However, during the summer heat, it is perhaps safer to mow the lawn early in the morning or late in the evening - safer for both the user and the cut grass/lawn!

The maximum, no-load blade speed is 2800 rpm, ensuring clean cuts with the sharp blade.

Cutting height is adjustable using a single lever, featuring 6 positions: 1 1/2" (41 mm), 2" (51 mm), 2 1/2" (65 mm), 3" (77 mm), 3 1/2" (93 mm) and 4" (107") - be sure to adjust the cutting height to the grass, season, heat, moisture, etc.

Ego Power+ LM2100SP features foldable handles, allowing the user to store the mower either horizontally or vertically, saving storage space.

Note: Although vertically stored Ego Power+ LM2100SP is rather stable, don't let pets and kids play around it - if pushed with enough force, it can fall down and hurt somebody or damage something. Safety first!

Long Story Short: If you are looking for a cordless lawn mower that features power, almost like a gas unit, but emit no fumes and is rather quiet during mowing, consider Ego Power+ LM2100SP.

If you don't already have a 56V 7.5Ah battery and the required battery charger, the initial investment is perhaps a little bit larger, but in the long run, it allows the user to purchase other Ego garden tools without the battery at very affordable prices, saving the money in the long run.

Of course, other batteries may be used as well, but the smaller the battery, the shorter the running time on a single battery charge. And here is where 2 or more batteries and a rapid charger may come in very handy.

Greenworks GLM801602 PRO 21-Inch 80V Cordless Lawn Mower

Greenworks GLM801602 PRO is a cordless lawn mower, featuring a serious 80V operating voltage, a steel 21-inch deck, a high-torque brushless motor, large wheels, vertical storage, etc.

Greenworks GLM801602 PRO is designed for both commercial and domestic use, differing only in warranty. It can be purchased as a 'bare-tool', with 2 Ah and 4 Ah batteries, with 4 Ah batteries being recommended.

Greenworks GLM801602 PRO is a large and sturdy cordless lawn mower. It weighs 79.5 pounds (~36 kg) and features a wide, 21-inch (~53.3 cm) deck.

Since the unit is made for both commercial and domestic use, most parts are made of steel, leading to a slightly larger weight but increasing the durability of the lawn mower.

To increase the maneuverability and decrease the stress on the lawn, Greenworks GLM801602 PRO features 7-inch (17.8 cm) front and 10-inch (25.4 cm) rear wheels.

The unit also features a 7-position single lever cutting height adjustment, ranging from 1-3/8 inch to 3-3/4 inch (3.5 - 9.5 cm) cut.

Greenworks GLM801602 PRO comes with a 3-in-1 design for mulch, side discharge, or rear bag operation.

Conversion from one mode of operation to another can be done quickly and easily.

Note: Greenworks GLM801602 PRO is easy to use and maintain lawn mower, but in order to use it fully and safely, when the unit arrives, read the manual first.

greenworks pro 21 inch 80v lawn mower glm801602 2To help with the storage, Greenworks GLM801602 PRO can be stored vertically, greatly saving storage footprint area - although the unit is stable in a vertical position, don't let kids or pets play around it since if it is pushed strong enough, it can tip over and cause some damage, or worse, injuries.

To improve performance and efficiency, Greenworks GLM801602 PRO features the so-called 'DigiPro', a digitally controlled brushless motor, and 'SmartCut Technology', which improves performance and extends the run-time by automatically adjusting the power based on the grass height and toughness.

Since it is powered by an onboard battery, Greenworks GLM801602 PRO features several more improvements over corded or gas-powered lawn mowers:

- very quiet during operation,

- no smelly fumes,

- no fuel/oil mixing,

- no spark plug/easy to start,

- no power cord to pull around,

- easy and simple maintenance, etc.

 Of course, the biggest drawback of cordless lawn mowers, in general, is the amount of energy stored in the onboard battery. Greenworks GLM801602 PRO features 80V(!) electric system and can operate using 2.0 Ah and 4.0 Ah lithium-ion, power fade-free batteries.

2.0 Ah battery stores enough energy for up to 20 minutes of operation, and 4.0 Ah battery stores enough energy for 40-45 minutes of operation - in real life. According to the manufacturer, 4.0 Ah battery can provide energy for up to 60 minutes, but that is in ideal conditions.

Note: when mowing high or tough grass, even a 4.0 Ah battery's operating time is shortened to 25-30 minutes.

greenworks gba 80400

Since Greenworks GBA80200 and GBA80400 are lithium-ion batteries, a standard Greenworks GCH8040 charger can charge a 2.0 Ah battery (GBA80200) in 30 minutes and a 4.0 Ah battery (GBA80400) in 60 minutes, ensuring almost no downtime with just two batteries.

Note: lithium-ion batteries controlled via onboard electronics are safe batteries, but in order to prolong their operating life, don't charge them right after use and don't use them right after charging - let them cool first for at least 10-15 minutes.

When charging lithium-ion batteries, be sure to always use battery chargers recommended by the battery manufacturers, in this case, that is Greenworks GCH8040 rapid charger.

Few other brands manufacture batteries that are very similar in appearance to Greenworks GBA80200 and GBA80400 but can fit only after modifying these batteries - this is not only not recommended but can be dangerous and can void the warranty.

For domestic use, Greenworks GLM801602 PRO comes with a 4-year limited warranty on the lawn mower and a 2-year limited warranty on the batteries. Nice warranty conditions for such a unit.

Greenworks also manufactures a whole range of other cordless tools and accessories (40+ models) that can be powered via GBA80200 and GBA 80400 batteries, making future purchases much cheaper since the user is buying only the 'bare-tool'.

Even if you are not interested in future purchases of Greenworks tools, having a cordless lawn mower like Greenworks GLM801602 PRO can save time and effort when keeping your lawn properly mowed.

Of course, there are many other cordless lawn mowers on the market, offering great performances at acceptable prices.


All-in-one Electric Mower Units

A special type of lawn mower is an all-in-one unit. Such units combine the electric lawn mower, lawn edger, and trimmer in one unit.

They can be corded or cordless and are easy to use.

On the other hand, they often lack some of the features that 'specialized' units have, for example, the grass catcher bag is often missing.

Since the price of the "full size" lawn mowers is quite acceptable, if you have any larger area of grass in your garden, go for a lawn mower with a grass catcher bag - it will save you time and work.

On the other hand, if you don't have a need for a bigger unit, these all-in-one units are perhaps just what you need.

BLACK+DECKER BESTA512CM 12" 3-in-1 Compact Electric Lawn Mower

BLACK+DECKER BESTA512CM is a lightweight and very compact, 3-in-1 yard tool designed to be used as a corded walk-behind lawn mower, edger, and trimmer.

BLACK+DECKER BESTA512CM is best suited for yards up to 1200 square feet (~112 square meters) or as a second lawn mower for larger yards that have slopes and hard-to-reach surfaces.

BLACK+DECKER BESTA512CM is designed for small yards and for areas where larger mowers have issues with doing their job. Also, it is designed for both edging and trimming.

BLACK+DECKER BESTA512CM is an electric, corded unit, being powered with 6.5 Amps motor. The cutting path is 12 inches (~30.5 cm), allowing the user to easily mow a smaller yard.

af 100Unlike most lawn mowers that use blades to cut grass, BLACK+DECKER BESTA512CM is a string trimmer/edger/mower.

It uses a single standard 0.065-inch (~1.65 mm) line via an Automatic Feed Spool (AFS), allowing the user to focus on the task ahead. The model number for the Auto-Feed Trimmer Line Spools is AF-100 and can be ordered online when required.

Maximum string speed is 8000 rpm, allowing it to easily cut tough grass and weed.

When mowing the grass, the unit cuts grass rather evenly, especially when the height difference between new and old grass is not large.

Also, the unit doesn't feature a collector bag, so grass clippings are left on the lawn.

BLACK+DECKER BESTA512CM weighs 9.9 pounds (~4.5 kg), with the most weight, in lawn mower configuration, resting on four wheels.

As an electric lawn mower, BLACK+DECKER BESTA512CM features two cutting heights: 1.6 inches (~4 cm) and 2.4 inches (~6 cm). Unit physical dimensions are 37.63 x 15.31 x 7.38 inches (~95.6 x 38.9 x 18.7 cm).

Note that the handle is adjustable, allowing the user to set its length to the most comfortable position.

One of the important accessories for corded lawn mowers is an extension cord.

BLACK+DECKER BESTA512CM draws 6.5 Amps at 120 volts, requiring the extension cord to be dimensioned accordingly - the extension cord doesn't come by default!

When choosing the proper extension cord, go for a brightly colored extension cord designed for outdoor use, which is thick enough to avoid unnecessary voltage drop and energy loss.

Cable length depends on the yard size, but for example, 50 feet (~15 m) long 16/3 cord (16-gauge, 3-wire extension cord) is rated ~13 Amps, while the similar 100 feet (~30.5 m) long 16/3 cord is rated at 10 Amps.

6.5 Amps max of BLACK+DECKER BESTA512CM is not an issue for such a cord.

Of course, the cord must be in good condition.

Note: although BLACK+DECKER BESTA512CM uses 0.065 line for cutting grass and weed, and NOT blade, don't run it over extension cord during operation. Better safe than sorry!

Long Story Short: If you are looking for an affordable and versatile 3-in-1 mower/edger/trimmer tool, consider BLACK+DECKER BESTA512CM.

It can reach and mow areas that are problematic to larger lawn mowers and can replace a few more tools as well, saving time, effort, and in the end - money.
