Here are the five best self-propelled lawn mowers that have risen to the top of our list, based on the criteria beyond.

1. Greenworks PRO 21-inch 80V Self-Propelled Lawn Mower

Greenworks PRO 21-inch self-propelled lawn mower stands at the top of the best-seller lists, so we had to lay our hands on it and give it a try.

Did it leave up to the apparent expectations?

We are happy to say “yes,” and let’s see why.

This is a cordless self-propelled lawn mower, which means you won’t deal with any cables, and you can cover a large area without any interruptions.

The battery and the charger were not included in our purchase, but you can choose to buy it with a 4Ah battery or two 2Ah batteries. If you go for this, we suggest getting the former. It is worth the extra cost, as you’ll get up to 50 minutes of runtime on a single charge.

It has a brushless DC motor that delivers exquisite performance, and equals the power of a 160cc gas engine. It comes with a rear grass bag that has a volume of 50 liters and a single lever for height adjustment.

But it’s more than the hardware that makes this device perfect for your lawn maintenance.

Greenwork’s breakthrough is their Smart Cut Load sensing technology, which accounts for incredibly easy operation of this lawn mower (along with the fact that it is self-propelled). 

All of these enhancements can be seen on three levels of operation: mulching, bagging, and discharging grass clippings. So, it is exceptionally versatile, as well!


  • Great value for the price
  • Brushless motors are more reliable and less prone to damage
  • High-quality steel deck
  • Optimal wheel size (10 inches)
  • Smart Cut technology
  • Fast charging time
  • 4-year warranty (2 for the battery)


  • None!

Our second pick features an extraordinary quality of the cuts and immense productivity.

The chief attributes of Lawn-Boy 17734 are its powerful Gross Torque Kohler OHV engine and the Rear Wheel Drive System that provides smooth traction and control on any type of terrain.

Besides, this engine is approved by the CARB (California Air Resources Board), meaning that you’re going full-on environmentally friendly! As for the size of the wheels, the front ones are 7 inches in diameter, whereas rear are 8 inches.

The feature that enhances the efficiency of this lawn mower is the 2-point Height-of-Cut System that allows you to switch the cutting height while working (from 1.25 to 3.75 inches). This versatility and range are appropriate for any size of your lawn!

A large bag capacity and the fact that you get a bottle of oil with the purchase added to this mower’s grade.

All of these characteristics automatically balance the performance and design of this lawn-boy, so that it is as handsome as it is powerful!

Finally, the manufacturers offer a 3-year “Try-Start Commitment” plus a 2-year standard warranty. What does the former mean? 

Well, it means that you get a guarantee that the engine will start on one or two pulls for that period! This is a testimony to its quality and durability.

  • 3-in-1 cut system (mulching, bagging, side discharging)
  • 4-stroke engine
  • Easy to use
  • Heavy-duty machine
  • Efficient speed control

Equipped with a 159cc OHV gas engine that features recoil and auto choke, Craftsman’s self-propelled lawn mower found its way to our list.

While it has a slightly robust heavy-duty design, its brushed stainless steel red finish adds to its modern and sleek look.

Thanks to the front-wheel-drive (meaning that the front wheels are significantly smaller in diameter than the rear ones), it is easy to control this device on any sort of terrain, even steep hills. The dimensions are 7 inches for the front-wheels and 11 for the rear.

Not only can this lawn mower deal with any kind of terrain, but it allows you to cut any kind of grass. There are as many as six heights settings, covering the range of around 5 inches, which earned this device the title “the most versatile self-propelled lawn mower”.

Oh, and you can also control its speed! The harder you pull this machine, the faster it goes.

As you can see, this lawn mower can basically do anything.

What is more, it comes with a large bag and a starter bottle of oil.


  • Efficient pull-to-start
  • Versatile (front-wheel push, adjustable cutting height & speed)
  • 3-in-1
  • Efficient engine
  • Strong and durable wheels
  • 2-year warranty


  • No detachable fuel filter
  • More difficult to maintain than some other models

Powerwork’s highest-end self-propelled lawn mower deserved a place on our list because it combines precision and power.

Once you start up this lawn mower, it basically runs itself, picking up 99% of all kinds of grass, thanks to its powerful 60V brushless electric motor. Generally, this kind of lawn mowers showed to be a bit more durable than the gas ones.

It did great on both short and long grass, and it is good at maneuvering around the obstacles that can get in the way. Apart from its quality construction, the 3-in-1 feature (mulching, rear bagging, side discharging) accounts for this.

It has many extra features, such as the ability to adjust the height via a single lever to one of the seven positions, and variable speed control. Also, you can store it vertically so that it takes up less space!

Another one of its beneficial characteristics is the rear-wheel-drive system, meaning that the front wheels are smaller than the rear, which makes it easier to operate on all kinds of terrain.

Our model came without the battery, but for a few extra bucks, you can order it with a 5Ah Lithium-Ion battery, which allows you to work for around 45 minutes without interruption. If this is not enough for your needs, you can always buy an additional one and switch them between the charges.

Its price for this category is the only factor that kept it from receiving a higher rating. If the price was lower, it might have also been our number one pick.


  • Very quiet operating
  • High-quality cuts
  • Sturdy steel cutting deck
  • Compact, vertical storage
  • Low-maintenance, especially compared to gas mowers


  • A bit pricey

As mentioned, electric mowers are better for the environment, and Snapper HD is no exception. It’s nice knowing that you’re reducing the emission of toxic fumes!

More importantly, it comes with a 5Ah battery that offers up to 60 minutes of runtime, so a little bit slower performance should not scare you – 60 minutes is more than enough!

We also like its easy height adjustment, with seven levels of cuts, and the 3-in-1 mulching/bagging/side discharge decks that easily adapt to your style.

All in all, this self-propelled lawn mower is ideal for city-sized yards,  is durable and built to last, and it offers thorough noiseless operation.

Key Factors To Consider When Buying A Self-Propelled Lawn Mower

best self-propelled lawn mower

As with everything nowadays, you need to conduct a thorough investigation before you buy or invest in something. With so many products practically swamping the market, it’s tough to deduce which ones are worth your time and money.

Once it comes to committing yourself to an investment that could better your life significantly as buying a reliable and durable lawn mower can, you need to be safe and secure on all fronts.

This is why we handpicked some key features that you need to pay more attention to when shopping for the best self-propelled lawn mower!

1. Machine Maintenance

All your gears and gadgets need proper maintenance to function fully and without obstructions.

  • So, of course, maintenance is a crucial factor to consider when it comes to buying a machine such as a lawn mower.
  • Some models require less attention, but once they do, it is of vital importance that they are adequately serviced, whereas some of them need frequent check-ups that are minuscule but should not be ignored.
  • It is, therefore, essential to know what kind of approach you need to take with your new lawn-mower and what sort of preference do you have when it comes to maintenance. 

Do you prefer a hands-on approach to cleaning and taking care of your machines, or are you more of a once-a-year type of a person?

  • All in all, you need to make sure that the mower’s blades are in check and that they are sharp since they will be doing the majority of the work. See Also: The Best Mulching Blade
  • Maybe your model of choice will need regular servicing in terms of oil changes. That’s why electric mowers require less maintenance than gas-powered ones in the long run.

Make sure that you get to know what kind of demands you will have from your machine before making the purchase.

2. Speed

There are self-propelled lawn mower models on the market that possess only one speed variable, as well as models that are better equipped and covered in this area with various speed controls.

  • Depending on the size and the sort of your lawn, you might need more speed variables so as to take proper care of it.
  • Smaller lawns are, of course, better suited for the single-speed lawn mowers, while larger ones necessitate a variety of controls to be properly maintained.

However, if you have a fixed speed on your mower, you might have difficulties with changing the pace of your lawn mowing. So, it is better to have a variety at your disposal, whether you intend to use it or not.

3. Engine Start

When it comes to starting your engine on self-propelled lawn mowers, there are two choices that you need to consider – an electric start key or a pull cord (also known as rope, or recoil start).

  • While the former is generally more desirable nowadays, and easier to use – pushing the button is quicker than pulling a cord, and it requires less force – pull cord-start can be equally convenient.
  • It is good because you don’t have to worry about plugging-in or the battery, but simply pull the rope. What is important here is that you get a good model that will start up on one or two pulls.
  • The crucial thing is that the engine starts up immediately and without any problems, whether you decide to push or pull.

As always, we’ve got your back! All of our picks have a prompt and swift engine start.
