Best Cordless Lawn Mower for 2018

Eco-friendly, battery-based cordless lawn mowers are coming into their own. These mowers, which range from around $200 to $500, provide quieter, non-polluting operation for mid-sized yards with normal grass height. They run on rechargeable lithium-ion batteries, which are located either inside or outside of the lawnmower. Cordless mowers are environmentally friendly like corded mowers and possess the flexibility of a gas-powered mower.

Battery powered lawn mowers first made their appearance in the late 1980s, but it has only been in the last 10 years that battery-powered lawn mowers have really come to the forefront. New lithium-ion batteries are stronger and longer-lasting than any earlier models.

Read on to discover 5 cordless lawn mowers in different price ranges that we consider to be excellent, high-performing models.

HOW WE RATED THE MOWERS

We conducted wide-ranging research with the goal of providing you with reviews of five of the best cordless lawn mowers available today. We read and analyzed hundreds of reviews online, and took into consideration the particular merits of each lawn mower. 

  • What are the advantages and disadvantages of each cordless mower?
  • What type of warranty does each model have?
  • What is their particular cutting performance - do they mulch, bag, and have a side discharge feature?
  • What kind of power do they provide and what is the average runtime of their batteries?
  • What about the ease and use of each model, how should they be stored, and how should they be maintained?
  • What is their environmental impact?
  • Finally, what is the difference between cheaper and more expensive models, what are the top-rated and best selling brands, and how much should you expect to pay for one of these cordless electric mowers?

RELIABILITY (WARRANTY)

A number of different warranties are available for the 5 different models of cordless mowers that are reviewed. The EGO Power+ provides a 3-year battery warranty for kits only, plus a 5-year tool warranty. The Greenworks Twin Force 40V mower offers a 4-year limited warranty. The Black & Decker CM2040 provides a limited 2-year manufacturer warranty, and the WORX 24V offers a robust 3-year warranty. The Snapper XD delivers a five-year tool warranty and a two-year battery warranty.

POWER (VOLTS)

Rechargeable batteries are available in an assortment of voltages. A good rule of thumb in that the higher the voltage, the better the torque is, which results in a better, cleaner cut. The models reviewed batteries come in a variety of voltages. Leading the pack is our most expensive reviewed mower, the Snapper XD SXDWM82K, which features 82 volts and a runtime of 45 minutes using a 2AH battery (more runtime is available if you purchase a separate 4Ah or a 5Ah battery). Our contender for 2nd place in voltage is our number one pick, the EGO Power+, our second most expensive model, with a voltage of 56.

CUTTING PERFORMANCE (MULCHING, SIDE DISCHARGE, BAGGING)

We have examined the particular cutting performances of each model of lawn mower reviewed.  The EGO Power+ mower is widely praised for its superior bagging, mulching, and use of its side-discharge chute. Mulching appears to be this machine's most convenient and most popular option. When the EGO Power+'s mulch plug is inserted, it finely mulches and discharges out of the mower bottom while the mower moves forward. The manufacturers are considering adding a vacuuming function to this first-class mower.

The Greenworks Twin Force mower provides dual blades for a finer quality cut and exceptional bagging and mulching capabilities. The Troy-Bilt TB370 is renowned for its excellent 3-in-1 capabilities to provide an even, clean cut and comes with a separate mulch bag. The Black & Decker Lithium 3-in-1 cordless mower is recommended for mulching thick grass, and feeding the clippings back through the blade finely chopped up. The Worx WG775, the least expensive model we've reviewed today, has been praised for mulching the grass so well that you won't discover any longer pieces or clumps of grass scattered all over your yard.

STORAGE

Some smaller mowers can fold up and can even fit onto a shelf. The WORX WG775 is one of these. The EGO Power+ folds up easily for upright, compact storage by rotating the handle to the locked storage position and rolling it to the desired location. The Greenworks 25302 provides convenient fold-down handles for easy storage. The Snapper XD claims to save owners approximately 70% of regular storage space with their machine's vertical storage capability. These machines can be kept easily in tight spaces in a garage or shed.

RUNTIME

Cordless mowers are available in 24, 36, 40, 56, 60 and 82V battery packs. It should be noted that just having a higher voltage does not always equate to having a better machine. It depends on its combination with Ah (amp-hour), which is the total amount of charge a battery can deliver in one hour. Buyers should also remember that these voltage rate runtimes are all based on having an entirely new battery. The runtimes of these machines are as follows:

  • A 24V battery provides 45 to 75 minutes
  • A 36V battery provides up to 80 minutes
  • A 40V, 56V, 60V, or 82V battery can run up to 90 minutes

EASE OF USE

The mowers reviewed have 3-in-1 functionality, good runtime, are lightweight, and feature easy to use functions like push-button starts, single levers, 4-wheel adjustability, good batteries, and fold-up options for storage.

WHY BUY A CORDLESS MOWER?

Why should you buy a cordless lawn mower? There are many great reasons:

  • Cordless motors need no gas, no fuel, and emit no pollutants.
  • They are super quiet. You'll love it, and so will the neighbors.
  • They're lightweight - Without a battery, they weigh under 50 pounds. With a battery, they usually weigh less than 80 pounds.
  • They need zero maintenance other than caring for the battery and sharpening the blades once a year.
  • They're long-lived. If you keep the blade arrangement and battery in good condition your cordless mower may be the last mower you ever buy.

PROS

  • 1
    You'll never have to purchase any gasoline for this machine (and gas prices are always rising).
  • 2
    Changing the oil, storing gasoline, worrying that old gas might be gumming up your carburetor, and tuning up your lawn mower are things of the past.
  • 3
    It's a green machine and very environmentally friendly.
  • 4
    A cordless mower produces virtually no noise compared to a gas-powered mower - You will be able to mow very early in the A.M. or much later in the P.M. without getting noise complaints from your neighbors.
  • 5
    You won't have to drag an extension cord around - Cordless mowers are more user-friendly. They make the task of mowing both quick and easy.
  • 6
    Cordless mowers are very neighbor friendly since they're so quiet and don't emit fumes.
  • 7
    They are very easy to start - Just press a button, then squeeze the handle, and you're ready to go.
  • 8
    Newer cordless mowers offer gas mowers a run for the money as far as power goes - They'll give your lawn a clean cut and give you enough run time to complete the job.
  • 9
    The majority of cordless motors weigh at least 30 to 50 pounds less than their gas-mower counterparts.
  • 10
    Cordless mowers are compact - Since there's no gas tank, there's no need to be preoccupied about spillage. The majority of cordless motors can be stored folded down, and there are some that can be stored vertically.
  • 11
    Lithium-ion battery technology has advanced in the last few years, allowing cordless mowers to compete with gas mowers in cutting time and power.
  • 12
    Some mowers have removable batteries which allow the user to have multiple batteries. One can be in use with a full charge while the other battery is charging.

CONS

  • 1
    A cordless mower will have less power than a gas mower, and the power output isn't consistent.
  • 2
    Runtime might be an issue if you have a larger property.
  • 3
    Too tall or thick grass will put a great deal of strain on an electric motor and battery. 
  • 4
    It will be harder to find a mechanic with a cordless model.
  • 5
    As the battery loses its charge, bagging, mulching, and cut quality decline.
  • 6
    Unsuitable for rough mowing conditions.
  • 7
    Recharging can take 12 hours.
  • 8
    Cordless mowers cost more than corded mowers (they compare in price with gas-powered mowers).
  • 9
    A cordless battery-powered mower has to be charged every time it is going to be put away. The mower will be out of commission unless there are multiple batteries available.
  • 10
    Most battery-powered mowers on the market today are not self-propelled.

WHAT TO LOOK FOR IN A BATTERY POWERED MOWER

What are the best features of a battery powered mower?

Number one on most buyer's list is the fact that the mower will have a lead-acid or lithium-ion battery to propel it, so you'll never have to drag an unwieldy extension cord around the yard. Typically, the more volts that a battery generates, the longer amount of time a motor can run, increasing the amount of grass you can cut. Newer cordless batteries hold a charge much longer than their predecessors, and many of these batteries can be recharged approximately 500 times.

Second, on the list of your battery powered mower is just that - a battery and not a gas-mower. You will have no gas filters, oil, or spark plugs to change, which translates into zero emissions, very low noise, and no gas to deal with. It is estimated that every summer in the US approximately 17,000,000 gallons of fuel is accidentally spilled while performing lawn care activities!

Third, compared to using a corded lawn mower you will enjoy greater mobility, you'll save time not having to deal with extension cords, and you'll never have to worry about running over a cord!

Find out how much runtime you'll get on a single battery charge. Check out the mower's cutting capacity (battery and deck width). Decide whether you want a push mower or a self-propelled mower. Decide what cut modes you want in a cordless mower - does it have mulching, collecting, and side discharge capabilities?

ENVIRONMENTAL IMPACT

How green is your battery-powered mower? The short answer is - very! Electric mowers generate zero tailpipe emissions, and that means no unburned hydrocarbons and carbon monoxide gets into the air. They use a small amount of electricity each time you mow. Even after taking into account any power plant emissions, electric mowers beat gas motors with an incredible 99% reduction in nitrogen oxides, methane, and carbon monoxide, and they also provide a 38% reduction in carbon-dioxide. The most pollution you will generate is when the battery dies - It is usually crushed, frozen, and then tossed into a landfill, contributing to general landfill waste.

MAINTENANCE REQUIRED

About the only maintenance, you will be required to do is sharpen the blades once each season. Dull blades will decrease the efficiency of the battery. First, remove the battery, Second, take out the blade, clean it, and then sharpen it. You can do this by clamping your blade into a vice - then file both edges using a fine-tooth file at the same angle of the original cutting edge. There are videos available online that will show you exactly how to do it.

Clean it after mowing. Store it in a shed or a garage. Take good care of the battery and charge it according to manufacturer's instructions. Remove the battery if you're not going to be using the mower for a long time. 

DIFFERENCE BETWEEN CHEAP AND EXPENSIVE MODELS

What are the major differences between cheaper cordless mowers and more expensive mowers? We're glad you asked!

CHEAPER MOWERS

  • The parts used in your mower will definitely be of inferior quality.
  • A less expensive mower will have less maneuverability.
  • Cheaper mowers will have shorter cutting widths - say 14" - which means many more passes over your lawn to get the job done.
  • Smaller batteries and voltage will be the norm. If you have a smaller lot - 1/4 acre or less - then the battery runtime of the cheaper cordless mowers (25-45 minutes) will be enough for you to complete on one charge.
  • Cheaper mowers usually will not handle taller grass well. If you use it on tall, thick grass, you will put a strain on both the electric motor and the battery. Lithium-ion batteries are capable of heating up and making the circuitry turn off the battery momentarily to preserve it.
  • Mowers like the 14" Worx Mower makes you adjust each wheel individually.
  • Cheaper mowers are more likely to have lead acid batteries that are 15 to 25 pounds heavier that could take up to 12 hours to discharge. This will be very inconvenient if you have a larger yard, and most people solve this dilemma by purchasing multiple batteries.
  • Our least expensive review mower, the WORX 24V 14" Cordless Lawn Mower with Removable Battery and Easy-Start feature, is currently selling for about $200. It weighs only 33 pounds, has a push-button start switch, and an ergonomic upswept handle. Some reviewers mentioned that the battery only lasts about 15 minutes before dying and stopped holding a charge at all after only 3 months. Another person said that they needed 2 fully charged batteries to mow 1/4 acre of lawn. It also immediately stops cutting when the bag begins to fill up

MORE EXPENSIVE MOWERS

  • A more expensive mower will have a wider cutting width, up to 19" or 20".
  • Higher priced mowers will have a 1-lever height adjustment which will allow you to adjust all 4 wheels at once.
  • More expensive mowers will offer 3-in-1 functionality and include items like grass catchers, mulching plugs that are built-in, and fabric or plastic containers for grass clippings. They may also feature a switch located on top of the steel mowing deck that will flip easily from mulching mode to grass collecting mode.
  • Pricier mowers will usually feature lithium batteries that charge in as little as 30 minutes.
  • Our editor's choice, the EGO Power" 20" 56V Lithium-ion Mower currently runs at about $450. For this amount of money, you will get weather-resistant construction, an advanced arc-lithium battery plus rapid charger, a 30 minute charge time and a 45 minute cut time. It also features LED headlights for 24-hour mowing.

HOW MUCH SHOULD I EXPECT TO PAY?

A good cordless electric lawnmower can cost upwards of $600, which means that they are more expensive than many comparable gas mowers. Electric mowers usually run $50 to $100 more than a similar gas-powered mower. Fortunately, the mowers that are reviewed here today are all great models, and their price range runs between $200 and $500, with a median price tag of $350. You can also get back some of that upfront cost quickly by not needing to pay for oil, gas, or any engine maintenance. The most significant cost you will have in the future will be to replace your battery, which usually costs about $150 to $200.

CONCLUSION

After a very extensive review of cordless electric lawn mowers, we strongly recommend the EGO Power+ 56V 20" Lithium-ion Cordless Lawn Mower with a charger kit and a 4.0Ah battery. This lightweight, quick charging powerhouse is a match for any gas-powered mower. It has a 20" deck, a 5.0Ah battery which can charge up in 1/2 an hour and it's extremely quiet. It comes with headlights, a grass bag, a mulching insert, and a side discharge chute, and is surprisingly easy to navigate. It also has the best warranty around - a 5-year warranty on the mower, and a 3-year warranty on the batteries.
