Looking for a reliable lawn mower to quickly tidy up your garden? Let the DeWalt 20V MAX do all the legwork for you.

Coming from a tried and tested brand that manufactures high-quality gardening tools, you won’t regret getting this machine.

To find out if it fits your needs, we prepared this DeWalt lawn mower review to cover all your bases.

In fact, you’ll find plenty of reasons to love this cordless lawn mower.

DeWalt Lawn Mower Review

The DeWalt lawn mower is a cordless, battery-powered machine with a wide cutting width, perfect for use in trimming medium gardens and small yards.

It’s also very versatile, considering its mulching option and six unique cutting heights.

All in all, it is built with exceptional quality and is quite frankly the perfect option for battery-powered mowers.

Who Is This Product For?

The DeWalt lawn mower is designed for homeowners with small to medium yards to tend.

Although its 40-minute battery charge allows you to use it in larger yards, it is still best for small to medium yards.

If you are a new gardener not used to operating gas engines, this model could be what you’re looking for.

One advantage of this lawn mower is that it needs little to no maintenance.

Compared to gas-powered units that need frequent oil changes, fuel filter replacements, and carburetor cleaning, it is a breeze to maintain.

If your neighborhood has noise restrictions that prohibit you from mowing using a gas-powered mower, we highly recommend the DeWalt 20V MAX.

Although not entirely silent, it is quieter than gas-powered units.

That said, this model does not work well with moisture.

You might be better off investing in a more powerful gas-powered unit if it frequently rains in your area.

The same can be said if you only have time to mow your lawn early in the morning when dew is still on the grass.

What’s Included?

The package comes with one DeWalt 3-in-1 cordless lawn mower and two 20V MAX lithium-ion batteries.

There is also a standard charger, a collection bag, a mulching plug, and a mulching plug safety key.

All these add-ons ensure easy but powerful and efficient use of the machine.

For maximum performance and extended runtime, you can pair the DeWalt lawn mower with any of DeWalt’s 20V MAX batteries.

These high-capacity batteries are already included in the package, so you won’t have to purchase them separately.

Overview of the Features

The DeWalt lawn mower is in a league of its own when it comes to electric lawn mowers. Here’s why:

  • Decent Cut Quality

This unit’s cut quality is beyond expectation, especially compared to other electric mowers.

Bagging, mulching, and side discharge are all highly effective, thanks to the 20V MAX’s three-in-one feature.

The cut evenness also leaves no complaints; you can even adjust the cutting height.

Depending on your preferences, you can choose from six cutting heights from 1 1/2 inches to 3 1/2 inches.

  • Outstanding Runtime

Most electric lawn mowers fall short on the run time department, but that is not true for this DeWalt lawn mower.

The machine runs on two 20V batteries, providing an impressive run time of 40 to 45 minutes.

This is more than enough to cover a quarter-acre lawn for most average cutting.

  • Great Build Quality

The DeWalt 20V MAX has a 21 1/2-inch steel deck known for its excellent durability.

However, if you prefer a mower with a horizontal bar, you might need time to get used to its handle’s angular design.

The mower has two handle heights that add to its flexibility. Moreover, this design choice is great for tall and short users.

  • Neat Safety Features

Aside from the On/Off button, this DeWalt lawn mower boasts a safety feature in its secondary lever that prevents unexpected start-ups.

You will also get a safety key to keep accidents at bay. This safety key needs to be inserted into the console to start the lawn mower.

With this, you’d be confident there will be no accidents involving children or during storage.

Try not to lose the safety key to avoid any inconvenience.


  • Reliable performance
  • Runs on batteries
  • Has a superb runtime
  • Moderate noise level
  • Has durable rubber tires
  • Great compatibility with other DeWalt products
  • Made with quality materials
  • Easy to store


  • Preferential angled handle
  • Extensive wheelbase
  • Unconventional drive system

How To Use the DeWalt Lawn Mower

One of the best things about the DeWalt 20V MAX Lawn Mower is its vertical storage design.

To start up the machine, position it horizontally on its wheels and turn the side knobs to turn the handle.

Next, adjust the handle either in a low or high position and turn the knobs to secure the handle position.

Now, you can open the plastic lid and insert two fully charged 20V batteries.

Pull the back flap upwards and put the clipping bags in place. After that, take the safety key and insert it into the console.

Press the center button on the console and pull the lever backward. Finally, start mowing.


The DeWalt 20V MAX lawn mower is top-notch in its class when it comes to durability, power, and quality.

However, one downside of the machine is its ergonomics, more specifically, the handle.

Although it has great ergonomic qualities, such as the adjustable handle, others are more focused on reducing discomfort and increasing efficiency.

If this is your case, we recommend the Greenworks Pro 80V Lawn Mower.

This lawn mower includes handle-adjustment features. It is also effortless to fold and unfold, saving extra energy for the actual mowing.

The build of the mower control makes it one of the best quality lawn mowers from Greenworks.

Is the DeWalt 20V MAX Any Good?

This DeWalt cordless lawn mower is levels ahead of the competition.

It is more than just your regular cordless lawn mower, as it boasts the capacity of something more powerful.

In fact, you’ll find that not only does it excel in power but also flexibility.

With its six cutting heights, adjustable handles, and vertical storage, you will appreciate both the comfort and power it gives you.

We hope this DeWalt lawn mower review gave you enough information to let you confidently decide which model to invest your money in.
