Our Verdict

The Greenworks 48V 20-inch mower is perfect for smaller yards, and will fit in nicely if you use the Powerall battery system of tools. Those with larger yards should look elsewhere, though.


  • Small, light, and easy to handle
  • The Powerall system is excellent
  • Relatively quiet cutting


  • Limited range
  • Limited cutting power

The cordless Greenworks 48V 20-inch 1313802 is a battery powered mower intended for smaller yards. It forms part of Greenworks’ larger 24 Volt Powerall battery platform of household products, with numerous other gadgets running off the same type of power source - very handy if you’re already invested in this ecosystem. This particular mower is designed to be lightweight, portable and easy to use, not to mention quiet.

That swappable Powerall battery also makes the Greenworks 1313802 a very different proposition from many of the best electric lawn mowers. In our Greenworks 48V 20-inch Brushless Lawn Mower 1313802 review, we break down the various features of this mower, its overall design, and how it could benefit your garden this summer. 

We also compare it on all those points to other top-rated mowers of a similar price range, so you can see if it’s good value for you. Some users rate it as a good supplemental mower for very large gardens with spaces that even the best riding lawn mowers can’t quite reach, so it’s more versatile than it first appears.  

Greenworks 48V 20-inch Brushless Lawn Mower: Overview

Type: Electric

The Greenworks 20-inch Mower aims to make mowing smaller yards as easy as possible. With a lightweight body and easy assembly, the device can be up and mowing incredibly quickly. 

Adjustable handles and 8-inch rear wheels make for a smooth pushing experience, which is coupled with a battery life ideal for smaller lawns. If you want a mower with an extended battery life, we’d recommend reading our Greenworks 21-inch 60V MO60L410 review - that one is more capable of covering larger yards.

The batteries are a particular draw for this product. Greenworks’ 24-Volt lithium-ion power sources are used in a wide variety of its products, and two batteries are used here to provide 48V power to this mower. Interestingly, the batteries can also function as portable chargers while you mow, making the mower even more multipurpose.

Greenworks 48V 20-inch Brushless Lawn Mower: Design

The Greenworks 20-inch mower is designed around easy storage and portability to help you maneuver small gardens. When working with a less sizable lawn space, maneuverability is key. As such, mowers that are easy to move around and compact are ideal for this type of lawn. 

Greenworks’ mower perfectly fits this brief. The light frame makes it easy to move, as do the fully collapsible handlebars. Further to that, the mower has a vertical storage option, which both makes it easier to store and also move. The LED lights that frame the outside of the mower are also useful, particularly on dim days, and are similar to those we talk about in our EGO Power+ 21-inch LM2102 review.

By designing the mower around Greenworks’ battery concept, the company makes it particularly convenient for customers already invested in its battery-based appliance platform. This design does not make it inconvenient, however, for users who only have the mower - in fact, battery charging and storage is much easier with this mower than many other competitors. 

Greenworks 48V 20-inch Brushless Lawn Mower: Features

Battery power has many benefits compared to gas power - yep, even the very best gas lawn mowers pose environmental issues. For the Greenworks 20-inch, battery power makes startup much easier. 

Another huge benefit is that the batteries make the mower extremely quiet. When you have a smaller garden, keeping noise pollution to a minimum is essential - especially if you’re looking to keep the neighbors on side! 

Each of the two Powerall batteries have USB slots to allow for mobile device charging. When used like this, the 24V batteries each become a 30,000 mAh power bank. Moreover, the mower comes with a free drill, also powered by the same battery. 

Putting this mower above other competitors like the Craftsman 105 is the 4-in-1 bagging/mulching function. The extra setting is a ‘turbo’ mode that speeds up leaf pickup. The seven position single lever height adjustment allows for an impressive range of cutting height. All of these features are backed up by a three year limited tool and battery warranty.

Greenworks 48V 20-inch Brushless Lawn Mower: How could it benefit you?

There are numerous benefits to a smaller mower using a replaceable battery rather than a gas or standard electric motor. It solves a lot of problems with other types of mower, especially if you have a smaller garden. 

The Greenworks Powerall battery solution is one that works particularly well for this. It even adds some extra features not usually seen together in other electric mowers, including:

  • A 4-in-1 bagging/mulching system, with a ‘turbo’ function speeding up mulching.
  • The two 24V batteries are quieter than regular mower engines.
  • These batteries also have USB slots each, allowing for portable charging.
  • Collapsible handles and small frame allow for easy storage and maneuverability.

For another mower with mulching capabilities, take a look at the EGO Power 21-inch mower instead - this machine offers gas-level muscle but is actually battery powered instead.

Greenworks 48V 20-inch Brushless Lawn Mower: User reviews

This particular version of the Greenworks 24V mower, the 1313802 model, has fewer reviews than other Greenworks products, but it follows the same trend of mostly positive ratings. Across the company’s own website, it has a rating of 4.8 out of 5 stars, with 4.7 out of 5 stars on Amazon and a 100% recommendation rate on Home Depot’s website. 

In general, customers who leave reviews praise the efficiency and ease granted by not having a cord. According to these reviewers, battery operation makes it much easier to set up initially. For this price range, being easy to assemble and start is a huge boon for a mower. The reviews for this product imply that the Greenworks mower is exactly that. 

An interesting use case for the mower is also brought up by several reviews. Many mention that the Greenworks 20-inch works as a great supplemental mower for larger gardens. 

Some larger gardens have odd areas that are difficult for most mowers to cover. One of the reviewers that mentioned this use also remarked that the mower had no problem dealing with 10-inch grass. 

Should you buy the Greenworks 48V 20-inch Brushless Lawn Mower 1313802?

If the lawn you’re planning to mow is on the smaller side, the Greenworks 20-inch is a solid investment. The combination of incredible maneuverability and dedication to simplicity at all times makes it a perfect no-fuss buy. If you have a larger lawn that tends to require over an hour of mowing, then this product does not have the power to do so. 

However, if you are looking after a smaller yard, and fancy a free brushless drill thrown in (with a battery that works for both), it is hard to go wrong with Greenworks’ entry. This battery has multiple uses across different Greenworks appliances, and also functions as a portable charger. For a handy, multipurpose mower, the Greenworks 20-inch 24V mower is the way to go.
