Review Summary

Greenworks PRO 80V Lawn Mower

Electric Lawn Mower

Overall Rating:  



Includes all the features needed for a high performance electric lawn mower! 


The build quality, as well as the battery quality, put this mower on par with any on the market today. 


Coming in with about the average price for an electric lawn mower, you get much more for your money than most mowers!

Take Away:

This mower is a great purchase for anyone looking for a cordless electric lawn mower. We recommend the Greenworks 21 inch 80V mower based on features, build quality, and value!

You will not find many mowers that can compete with this one, and for the price, we don't think you can find any better. The only con we have is the weight, but that comes due to the steel deck...and we like that trade off.


  • High Quality Steel Deck
  • Smart Cut Technology
  • Ball Bearing Wheels
  • Battery and Charger Included


  • Slightly Heavier Than Some Electric Mowers Due to Steel Deck

Key Features

Smart Cut Technology

The smart cut technology helps the mower adjust power depending on the thickness and length of the grass. This feature extends the amount of time your mower can run if cutting light grass, and helps to ensure a quality cut on thicker grass.

3-in-1 Discharge

Allowing for three forms of grass discharge allows you flexibility when it comes to how you mow your yard. You can choose between:

  1. Side discharge to throw the cut grass out to the side of the mower
  2. Rear discharge to allow for collecting the grass in the rear bag (included)
  3. Mulching

21" Steel Deck

The 21 inch deck allows for more grass to be cut on each pass, giving you a shorter mowing time. The steel construction gives much more durability to the mower, but does add a small amount of weight.

Ball Bearing Wheels

You don't know how helpful ball bearing wheels can be until you have mowed with other kinds of wheels. The wheels on this mower are amazing and help make your yard-work much more enjoyable.

This is one of our favorite features!

7 Position Cutting Heights

There are seven different blade heights to choose from on this Greenworks lawn mower. Not only do you have a ton of options for height, but you can adjust in one simple motion with the single lever height adjustment system.

Power Supply

  • Battery Stats: 80 volts/4Ah
  • Time to Fully Charge: 60 minutes (30 minutes for the 2Ah version)
  • Mowing Time Per Charge: 60 minutes

The quality of the battery is one feature that makes this mower shine. The short charge time and long run time make this a 5 star battery as far as mowers go.

By using the led power indicator you should be ready to mow knowing you have a hold of your power situation. As always, we recommend having two batteries for your electric mower. Keeping one backup ready, just in case, is always nice.

Another great feature is that you can use your Greenworks battery on other Greenworks battery powered tools!

You can also view the owners manual if you have further questions about what is included.

Mower Quality

This is one of the biggest reasons this mower is a five star mower. The steel deck adds great durability, and puts it on par with any gas mower. The all around craftsmanship makes this mower shine.

The 21" steel blade is also very high quality, and you can order a replacement/spare blade from the manufacturer. There are some on Amazon, but be careful not to order the wrong one as there are different 21 inch blades for different mowers.

What Comes with the Greenworks PRO 21-Inch 80V Cordless Lawn Mower

This depends on the options you choose. However, you typically get the mower, grass catcher, battery, and charger. You can also choose to only purchase the mower body itself if you already own other Greenworks products that allow you to interchange the battery.

There are also options that include self propelled function, side chute, more/different batteries, and chargers.

Replacement Parts

You can order replacement blades from Greenworks or other retailers. Just make sure you get the correct 21 inch blade that works with your mower. You can also purchase additional batteries, chargers, and other accessories.

Greenworks also sells batteries on Amazon that can be used as spares or replacement options. The price depends on the size of battery you choose to use.

Value Summary

While there are other mowers on the market that have similar features, and some with similar quality, you will be hard pressed to find one that combines both, along with the price of this one.

All of this makes this Greenworks cordless electric mower one of our most recommended options for your yard. It is a 5 star mower!

  1. Cleaning up the dead organic matter helps leave the grass open to the sunlight it needs. Many people believe the dead grass helps their yard and in some cases it does, but excessive dead grass lying around can do more harm than good, so be sure to rake up the dead grass to increase the livelihood of your lawn.

  2. All lawnmower batteries are rechargeable, however, they do not have unlimited life, they will have to be replaced occasionally. If you find that the mower is running strangely, or have troubles starting it up, it may be time to replace look for lawnmower batteries. There are two different types of batteries used in a lawn mower, 12-volt, and 6-volt. To find which type of battery you need for your lawnmower, the best thing to do is refer to your owner’s manual.
