By Corrie Pelc

If there’s one outdoor chore that universally everyone complains about, it’s mowing the lawn. Usually, the grievances stem from using a lawn mower that is loud, dirty, hard to push, and—especially back-in-the-day—hard to start and unreliable.

The good news is that lawn mowers have come a long way from your summers as a teen. Now lawn mowers are quieter and easier to both use and maintain, helping to make lawn mowing less of a complaint and more of a delight.

With so many lawn mower options available today, how do you know which is the right one for your lawn? We’ve put together what we hope will be a very informative and helpful guide in helping you pick a lawn mower for your needs.

How Do Lawn Mowers Work?

The main mechanism of any lawn mower is the blade—that's what cuts the grass. In today's modern lawn mowers, the blade is housed in a casing called the mower deck, which is normally made of steel or some other super-tough material. As the blade—or blades—spins and cuts the grass, the deck keeps the grass and anything else on the lawn from flying around and hitting the person using the lawn mower or anything else in the general vicinity.

On top of the mower deck and blade is the body of the lawn mower, which will either need to be pushed or guided by using a handle or steered if it's a ride-on lawn mower. Additionally, each lawn mower will have a way to get rid of grass clippings, either by depositing them into an attached bag or by gently dispersing them back onto the lawn, creating a convenient mulch cover.

Generally, lawn mowers are powered in one of two ways—gas or electric. For gas lawn mowers, you'll need to take into account the oil consumption as well as the gas usage. Electric mowers can either be corded or cordless, meaning they're powered by a rechargeable battery. 

Lawn Mower Types

Brand aside, there are plenty of types of mowers to choose from, and which one you choose will depend on a few factors of your lawn, like size and terrain.

Lawn mower engines are measured in "cc", or cubic centimeters, and can range from 140 cc to 190 cc. This is the measurement of the capacity of the cylinder in the mower's engine. Larger engines are better for tougher cutting conditions, like tall, wet grass and weed mowing. The average recommended range for an at-home lawn mower is around 160 cc.

Push Mower Types

A push or walk-behind mower is commonly recommended for yards smaller than one quarter-acre.

If your lawn is bigger than 2,500 square feet (about the size of a regulated tennis court), we recommend self-propelled lawn mowers, which work on a self-driving system and rely on you only having to steer it in the right direction. A self-propelled lawn mower typically has a bar that the user engages to start the propeller, and releasing the bar will turn the engine off or stop the blade, depending on the mower. Self-propelled mowers will save time and energy, because you won't have to expend extra effort in pushing the mower through challenging areas in your yard, like thick grass.

Self-propelled mowers will come with either front-wheel drive or rear-wheel drive, each one with unique benefits. Generally speaking, mowers with front-wheel drive are easy to turn and are best suited for flat-terrain lawns that might have obstacles like trees, corners, and lawn ornaments. Meanwhile, rear-wheel-drive lawn mowers can tackle bumpier terrain like hills and slopes and are ideal for wide-open spaces with fewer obstacles to mow around.

Riding Lawn Mower Types

Riding lawn mowers allow you to sit while mowing, take up more space, and cover ground faster, so they work best in yards bigger than a quarter-acre. There are two main types of riding lawn mowers: zero-turn mowers and tractor mowers.

Pro Tip: One acre of land is approximately 43,560 square feet. For reference, a football field is 48,000 square feet.

Zero-turn mowers are sit-down mowers equipped with two levers that control motors attached to their respective wheels on each side. Pushing the levers forward causes the mower to propel forward, while pulling backward will reverse the machine. To turn right, the user will push the left handle forward and vice versa to turn left. Once you get the hang of the steering mechanisms, zero-turn mowers are easy to maneuver and can quickly make 180-degree turns to mow patches you may have missed in a previous turn.

On the other hand, tractor mowers are a great option if your yard is over one acre big and is filled with slopes and hills. Tractor mowers are comfortable, and since they have bigger wheels and a stronger center of gravity, they can tackle slopes that zero-turn mowers can't. Like a car, a tractor mower has a gas pedal, brake pedal, and steering wheel. Keep in mind that lawn tractors have a wide turn radius, which will leave a patch of unmowed grass around each turn, so you will need to circle back to be sure that every blade is cut.

How to Select a Lawn Mower

Here are some factors we considered in deciding on our list of the best lawn mowers:

Choose Your Fuel: Overall, there are two main types of fuel when it comes to lawn mowers—the traditional gas-powered and the more recent electric-powered. For electric lawn mowers, you can choose between having a battery that needs to be recharged every time you mow or use a corded electric lawn mower, which can go for longer but is more restricted in terms of distance and mobility.

Know Your Lawn Size: Another major factor to consider is the size of your lawn. For example, battery-powered and electric corded lawn mowers are a better option for smaller yards, as they have some restrictions in either needing a recharge or being plugged in to operate. Also how large your yard is will determine if you need a walk-behind lawn mower — either a push or self-propelled model, depending on your needs — or a ride-on, tractor-style lawn mower. 

How Do You Like Your Clippings: Most of today’s lawn mowers will offer both bagging and mulching options for clippings. With bagging, the lawn mower will collect the grass clippings and place them in the attached bag. And with mulching, the mower will cut the clippings more finely and then disperse them as you continue to mow. In time, the mulched clippings will break down and return to the soil of your lawn, helping to provide nourishment. A third option a lot of the best lawn mowers offer is a side discharging option for the mulched clippings, so instead of dropping them behind the lawn mower they shoot them to the side. 

What Are the Best Lawn Mowers for 2021? 

To help you figure out the best lawn mower for your particular lawn, each lawn mower on our list has been evaluated and ranked for these main factors: 

  • Price: Thankfully there are great lawn mowers out there for all budgets. Keep in mind, some of the pricier mowers are known to withstand more usage, so consider that when determining your investment.
  • Mower Type: Is the lawn mower a walk-behind—push or self-propelled—or ride-on? If you have a lot of lawn to mow, or you're not as spry as you once were, this factor will be very relevant in your decision-making.
  • Power Type: Is the lawn mower powered by gas, corded electric or cordless batteries? This will determine for how long and how far your mower can go.
  • Engine Power: The more powerful the engine, the faster and more efficient the lawn mower.
  • Mower Start: How the lawn mower starts—is it a pull-start, push button or something else? It may seem like a small factor to consider, but it will play into how convenient it is to start and stop the job, as well as how easy it is to pause or take breaks.
  • Weight: How much the lawn mower weighs is important when you’re pushing it around your lawn. 
  • Mower Deck Size: The size of your lawn will help you determine the size cutting deck you need—generally the larger the lawn you have to mow, the larger the cutting deck you'll want. And the size of the blade inside the lawn mower will normally be the same size as the cutting deck, so a mower with a 48-inch cutting deck will have a 48-inch long blade.
  • Lawn Cutting Heights: Most of the lawn mowers on our list offer various heights the mower deck can be set to, allowing for different heights of grass.
  • Cutting Dispersal: As mentioned before, almost all of today’s lawn mowers offer at least two options for collecting grass clippings—bagging them or mulching them and dispersing them behind or to the side of the mower.
  • Adjustable Handle: Does the lawn mower’s handle adjust for different heights? This will play into how comfortable your mower is to handle.
  • Oil Change System: Does the lawn mower require oil changes, and if so, how easy are they to do? Mower upkeep can become more challenging if you have to weigh this factor into your workload.

The History of the Lawn Mower

Lawn mowers have come a long way since the very first lawn mower was invented back in 1830 by an English mechanic named Edwin Beard Budding, which was based on the same cross-cutting machinery he worked on and repaired in textile mills at the time. This prototype of a reel lawn mower—which uses blades that spin vertically to cut the grass in a "scissoring action"—was followed by the first US patent for a reel lawn mower in 1868 by Amariah Hills of Connecticut. 

In 1919, the world saw the first gas-powered lawn mower thanks to Colonel Edwin George of the United States. And although electric lawn mowers were first developed in the 1930s, consumers did not really take to them until much later.

How to Get the Most Out of Your Lawn Mower

Lawn mowers can be an investment, but the good news is that with a little know-how and some proper maintenance, they can last for many years. Here are a few tips on how to get the most out of your lawn mower:

  • Read the Manual. As with any new piece of equipment, first and foremost always take the time to read the instruction manual accompanying your new mower so you can learn about all of its features to get the most out of it.
  • Know Your Maintenance. Whether it's making sure the oil is topped off, the batteries are charged, or the mower is gassed up to go, make sure you know the proper maintenance procedures for your particular lawn mower and follow them. 
  • Stay Sharp. The blades are the most important part of the lawn mower, so keeping them sharp is vital as dull blades will not keep your lawn looking its best. Follow the manufacturer's instructions for sharpening the blades, and when in doubt, go to a professional.
  • Keep it Clean. Clean your lawn mower after every use to remove any clippings that may clog the mower, and to keep it from developing any rust on any of its metal parts. The instruction manual should include proper cleaning procedures for your particular model.
  • Store it Properly. When you're done with your mower, store it in an area that will protect it from the elements, such as a shed or the garage. You may even want to consider a lawn mower cover if you'll be storing it for a long time during the winter season.
