A Guide to Buying A Walk-Behind Lawn Mower 2018

Types of lawn mowers

A lawn mower is a term that describes a broad category of machines that use revolving blades to cut grass. The most primitive lawn mowers have fixed grass cut height and are not adjustable. The majority of lawn mowers available on the market today have master levers that let you adjust the height of the cut. Today we will talk about walk behind lawn mower reviews and compare some top rated walk behind lawn mowers.

Lawn mowers can be manual, with blades powered by muscle, or automatic. Automatic lawn mowers are usually powered by an electric motor or by an internal combustion engine that uses gasoline just like a car would.

What type of lawn mower is right for me?

Manual Mowers

If you have a very small lawn or a garden, the simplest unpowered walk behind mower with a fixed grass cut height may be right for you. Such mowers usually cost between $50 and $100.

Prices for riding mowers start at about $1,000 and go up to about $3,500 for professional-grade mowers with engines of 20+ horsepower, multi-bladed systems, parking brakes and other advanced features.

For most people reading this walk behind lawn mower review guide, a walk behind mower will be an excellent choice because of its versatility, ease of use and efficiency.

What to pay attention to when choosing a best walk behind lawn mower

Here are the most important factors you need to consider when deciding on what walk behind lawn mower you want to buy.

Width of the mower

The larger the width of the mower, the more grass you will be able to cut in one pass. For walk behind mowers, width usually varies between 14 inches for the small inexpensive models and 21 inches for high-end models.

Type of power

There are three types of power that you will find in top rated walk behind lawn mowers.

They are

  1. Corded electric engines

Corded electric mowers are the most inconvenient as you always need to be close to a source of electric power and you need to pay attention to the cord when cutting grass.

  1. Cordless (battery-powered) electric engines

When looking at battery-powered mowers, pay attention to how long the mower will last on a single charge. If you have several large lawns that you prefer to cut at once, a battery-powered mower may not be a good choice for you as you may need to recharge it several times to complete the job. The advantage of battery-powered walk-behind lawn mowers is that you do not need to deal with gasoline, which means no smell, no risk of leakage and higher overall safety. Such mowers are also much quieter compared to gasoline-powered mowers.

  1. Gas engines

Gas engines typically have more power than electric engines, which comes very handy if you have a large yard or a tough terrain. If you run out of gas, you can quickly refill the mower and continue working immediately.

The limitation of a gas engine is that it requires regular maintenance. You will need to keep the tank filled and check oil levels and filters on a regular basis. Gas mowers are also much louder compared to electric mowers.

The size of the engine

Find out the size of the engine. Engine sizes in walk behind mowers typically range from 140 cubic centimeters (cc) to 190 cubic centimeters. The bigger the engine, the easier it is to use the mower in tough conditions such as when cutting weeds, cutting tall and wet grass or mulching leaves.

How long does the mower last on one charge or fill-up?

If a mower has an internal combustion engine, find out the size of its fuel capacity tank. The size of the tank in a walk behind lawn mower is important for the same reason the size of the fuel tank is important in your car: the bigger the tank, the less often you have to refuel.

If a mower is powered by a battery, find out for how long it will last on a single charge. Next, think about the size of your property and decide if the mower with this battery size is going to be right for you.

Self-propelled versus walk behind (or push, or reel) mowers

walk behind lawn mower reviews, ratings

A self-propelled mower actually pushes itself to reduce the amount of work you’ll have to do compared to a push mower. With a self-propelled mower, you simply walk behind it to control its path, but you don’t have to push it.

There are three kinds of self-propelled mowers: front-wheel drive, rear-wheel drive and all-wheel drive.

Front-wheel drive mowers are a great solution for flat terrains. Rear-wheel drive mowers have more traction at the center of the device, which is helpful if you have to mow grass on uneven lawns. All-wheel drive units have power delivered to all four wheels and are suitable for both flat and hilly lawns.

Basic Functionality

Walk behind lawn mowers typically treat clipped grass in one of three ways:

  1. Mulch it, which means repeatedly cutting it until the particles become small and then discharge them
  2. Discharge clippings right away without cutting them
  3. Collect clippings and save them in a bag attached to the mower

There are mowers on the market that have all three of these functions.

Some mowers only have two. Mowers with two functions either a) store the clippings and mulch them or b) mulch them and discharge the clippings the way they are.

It goes without saying that if you want maximum versatility, you want a top rated walk-behind lawn mower that can perform all three of these functions.

Additional functionality and things to pay attention to

The location of gas and oil tanks in mowers with gas engines

You want a best rated walk behind lawn mower that’s easy to fill up, not the one where you have to perform an aerobic exercise every time you need to add gas to the tank. This is why you want to make sure that both gas tank and oil-fill are conveniently located.

Air filter

If you decide to get a walk-behind lawn mower with an internal combustion engine, it will have an air filter just like the one in a car. Make sure that the filter is easy to remove and replace. If you have to do a lot of work in dusty and dirty conditions, choose a top rated walk behind lawn mower with a large filter and a dirt-trapping surface area.

Blade brake

If a mower has a blade brake clutch, you will be able to stop the blade without stopping the engine. Walk-behind mowers that have this function are usually $75 to $100 more expensive than their counterparts, but this function is very useful and will extend the life of your mower if you spend a lot of time removing debris or toys from the lawns when using the mower.

Wash-out capability

If a mower has a wash-out nozzle, you’ll be able to connect the nozzle to the deck of the mower and use water to wash out grass clippings and debris from under the deck.

Big wheels

The bigger the wheels of the mower, the easier it will be for you to move your mower through rough terrains.

How they get you: how to make sure you are not overpaying when buying a walk-behind lawn mower


When you are buying a car, you will often see the MSRP for a stripped-down version without any features that you really want. Once you add all the features and options that you are really interested in, the price of the car will go up significantly and may even double.

When buying an inkjet printer, you will often pay very little for the printer, but a lot for the ink later. A cheap printer will also often come without the cords and without other basic accessories that you will have to purchase separately.

Some lawn mower manufacturers use similar strategies when selling their mowers. This is why you want to carefully inspect what is included in the price of the best walk-behind lawn mower. Here are some examples:

If it’s a plug-in electric mower, is the cord included?

If it’s a battery-powered mower, is the battery included? Is the battery charger included?

How many years does the battery last and what is the replacement cost?

Is the grass catcher detachable? Is it included? If it’s not detachable, how long does it last, is it easy to replace and how much does it cost?
