What to Consider When Choosing the Best Lawn Mower

When shopping for a lawn mower, it’s vital to consider several factors, including type, deck size, and fuel type. Ahead, learn more about these and other important characteristics of lawn mowers.

Types of Lawn Mowers

The first step to selecting the right mower is to first decide which of the three types of mowers best suits the yard.

Walk-Behind 

Walk-behind mowers consist of two different kinds of mower: push and self-propelled. Self-propelled mowers have power wheels that pull the mower forward. The operator controls the mower using a pressure-sensitive bar on the mower handle. Manual mowers have no power-assisted wheels and must be pushed manually by the user.

Riding

Riding mowers include zero-turn mowers, lawn tractors, and rear-engine mowers. Zero-turn mowers, the most expensive lawn mowers on the market, have a motor that sits behind the operator and are controlled using two levers. The mowers get their name from their ability to pivot 360 degrees in place. Zero-turn mowers also have very broad mowing decks. Their size and maneuverability make them ideal for cutting large lawns with obstacles the user must drive around.

Lawn tractors look similar to a farm tractor with a motor in the front of the mower. The user operates the tractor from a driver’s seat using a steering wheel. Lawn tractors have broad mowing decks but do not have the small turning radius of a zero-turn tractor. Rear-engine lawn mowers are similar to lawn tractors but have their engines in the rear. Rear-engine lawn tractors typically have smaller decks, though they allow for more visibility and nimbler handling for the operator.

Robotic

The newest type of lawn mower, robotic mowers look similar to robotic vacuum cleaners, only they are larger and have bigger wheels that enable them to move through grass. Robotic lawn mowers can mow a yard automatically while being operated via a smart device. These lawn mowers are powered by a rechargeable battery and can be programmed to mow the lawn at programmed times and intervals. These mowers require the user to set up wires in the yard that create boundaries for the mower so it doesn’t wander away. They also use laser-eye technology that spots obstacles in the yard so the mower can evade them.

Drive

Self-propelled mowers come in different drive wheel options including front-wheel, rear-wheel, and all-wheel drive. Front-wheel drive mowers are easier to turn by allowing the operator to raise the front wheels and use the back wheels to pivot. Rear-wheel drive mowers place the bulk of the mower’s weight over the drive wheels, creating better traction for climbing inclines and slopes. All-wheel drive mowers are well suited for homeowners with more extreme slopes and rougher terrain.

Cutting Width and Yard Size

A mower’s deck size determines the width of the swath of grass it can cut with each pass and hence how quickly it can mow the lawn. A wider deck also makes a mower less nimble, which can make it awkward to mow small lawns with flower beds, trees, and gardens to navigate. A walk-behind mower with a 20-inch deck is a good size for a smaller yard of up to about ½ acre. Larger yards of up to ¾ of an acre require a mower with a 22-inch deck. Riding mowers, which have decks that range between 28 and 46 inches, are a good choice for lawns of 1 acre or more.

Fuel Type

Lawn mowers can use three types of fuel sources: electricity, gas, and rechargeable lithium-ion batteries. Electric mowers supply a constant source of power; however, they are limited by a cord that connects to a standard wall outlet. This makes corded lawn mowers awkward to use, especially for larger yards.

Gas-powered lawn mowers provide the most amount of power and can run for hours on a single tank. However, gas mowers require more maintenance to keep in top condition and can produce exhaust fumes.

Battery-powered mowers run off large lithium-ion batteries. They are easier to start than gas-powered lawn mowers and create no exhaust fumes; however, they don’t produce as much power and are limited to about 45 minutes of runtime per charge. Battery-powered mowers are also significantly more expensive than gas mowers.

Blade Type

Mowers come in two blade types: the more common rotary and the up-and-coming cylinder. Rotary mowers are the type of blade found on most residential lawn mowers. They consist of a blade or blades that spin on a horizontal plane, cross-cutting the tops of grass blades to trim them to the desired height.

Cylinder blades, which can cut grass to a very low height without damaging it, have historically been confined to use on sports fields and golf courses. They consist of a rotating cylinder that is equipped with blades that wrap around the cylinder in a spiral pattern. The blades cut the grass using a shearing action that creates a cleaner cut than rotary blades, which can tear grass and leave a ragged edge.

While cylinder mowers make more precise cuts, they are not capable of cutting through taller grass. In fact, their cutting ability ranges from a height of about 2 millimeters to 35 millimeters. This limits this type of mower to varieties of grass that can survive being cut to a low height, such as Bermuda grass.

Disposal Options 

Mowers offer different grass-disposal options including side discharge, mulching, and bagging. Side discharge ejects the grass clippings out of the side of the mower. Mulching keeps the grass clippings under the deck, allowing the blade to cut them multiple times to produce a mulch that can nourish the lawn. Mowers that support baggers collect the clippings in a bag at the rear of the mower.

Additional Features 

Mowers come with additional features that make them easier to operate and maintain. These useful add-ons include mowing decks with hose attachments that make them easier to clean, switches that make it easy to change between cutting options, and easy-to-operate variable speed controls for self-propelled mowers.

Many riding mowers have LED headlights for nighttime mowing, cupholders for holding water bottles, and plush ergonomic seating for comfort. Mowers also feature different cutting heights, with higher-end models offering more options than lower-end models.

The list below includes some of the best mowers in the market by class.

Pushing the edge of lawn mower technology further is this robotic lawn mower from Worx. It functions similarly to a robot vacuum cleaner by mowing a preset area of up to a ½-acre on its own.

The Worx WR155 can also connect to a smart device, through which the user can program daily schedules or direct the mower to stop or start. It runs off the same Worx battery that powers the company’s other yard tools and will automatically return to its charging station when the battery gets low.

  • Deck size: 18 inches
  • Type: Robotic

  • Can mow up to ½-acre

Our Verdict

For its reliability, excellent cut, and user-friendly controls, the Honda 21 in. 3-in-1 Gas Self Propelled Lawn Mower is a worthy choice for those who can afford its higher price. Those in the market for a more affordable option who don’t mind pushing the mower themselves should consider the Craftsman M105 Gas Powered Push Mower.

How We Chose the Best Lawn Mowers

In reviewing dozens of lawn mowers, we considered several important features including power, reliability, deck size, and clipping-disposal options. Since mowers come in a variety of types, we limited our evaluation to mowers of the same type to get an apples-to-apples comparison. Riding mowers were compared to riding mowers, and self-propelled walk-behind mowers were compared with other self-propelled walk-behind mowers.

In terms of power, we only chose mowers with gas or electric motors that could capably power the mower’s deck size and wheels (if the mower was self-propelled or a riding mower). For battery-powered mowers, battery life was crucial in the selection process. Since lawn mowers tend to sit for long periods in the off-season, mowers with high marks for reliability ranked high. We also leaned toward models that offered more versatility with numerous cutting heights and multiple grass-clipping options.
