Buyers Guide

Shopping for a lawn mower can be confusing for a new homeowner who’s never had to think about lawn care tools before. There are so many different types of mowers, all with different features. Even when we’re only talking about gas lawn mowers, there’s a lot of information to unpack. 

Here, we’ll cover the basics to help you understand what we’ve been talking about throughout this guide. 

Push mower vs. riding mower

The difference between a push lawn mower and a riding lawn mower is fairly obvious. 

Push lawn mowers (sometimes called walk-behind lawn mowers) are the small ones that you walk behind and push around your lawn. For most suburban homes, a push mower should handle all your lawn’s needs. These mowers are best for lawns of an acre or less. (See our Best Push Lawn Mowers article for our top picks.)

When you have a larger property, pushing a 50-pound (or heavier) gas lawn mower can get exhausting.

Riding lawn mowers are the huge ones that you sit on and drive around the lawn like a vehicle, maybe with a cupholder so you can sip cold tea while you mow your grass in the heat. (Ride on over to our Best Riding Mowers article to check out our top picks.)

There are two main types of riding lawn mowers:

  • Lawn tractor
  • Zero-turn mower

Lawn tractors are the more traditional riding lawn mowers that you’re probably used to seeing. You control these with a steering wheel, just like a car or golf cart. Lawn tractors are more stable than zero-turns, so they’re the best choice for sloped or uneven lawns.

Zero-turn mowers can turn 360 degrees, and you operate them using one or two lap bars depending on the model. Zero-turns are faster and much more maneuverable than lawn tractors.

If you have a lawn of several acres to mow, a zero-turn mower will make your life easier. Beware that zero-turn mowers usually come with a higher price tag than lawn tractors.

What to look for in a gas lawn mower

Now, we’ll go over the factors we considered when choosing the best gas lawn mowers. These are the specifications you should look at to help you decide which mower will most likely be best for your needs.

Power: More power is the biggest advantage gas lawn mowers have over their electric counterparts. If you’re shopping for a gas mower, power is likely important to you. 

In a gas push mower, we determine power based on the size of the engine, measured in cubic centimeters (cc). Those with larger engines (higher cc) will have a higher potential power output. Most push lawn mowers have engines ranging from 140 cc to 200 cc. 

For riding mowers, we measure the power of the engine with horsepower (HP), as you do for a car. The more HP an engine has, the higher its power output. Most riding lawn mowers have anywhere from 14 to 24 horsepower. Those closer to the high end of that range are best for properties of several acres. 

Cutting width: A mower’s cutting width is determined by the size of the mowing deck. The wider the deck, the more ground the mower will be able to cover at once, and the fewer passes you’ll have to make to mow the lawn.

Keep in mind that wider mowing decks also mean worse maneuverability and more difficult storage. Smaller cutting widths may be better for homes with smaller yards and limited storage space. 

Weight: Weight is only important in push lawn mowers. Think about it: The heavier the mower, the sooner you’ll wear yourself out when pushing it. Unfortunately, gas mowers are usually the heaviest options. If weight is a big concern for you, you’re probably better off with a lightweight electric mower. 

Fuel capacity: The size of the fuel tank in a push mower doesn’t usually vary much, so you don’t have to pay that much attention to it.

If you’re shopping for a  riding lawn mower, however, keep in mind that a larger fuel tank means a longer run time. When you’re mowing several acres of land, you may not be able to stop mid-mow and refuel. That’s where thinking about fuel capacity becomes important. 

Maximum speed: Some riding lawn mowers can go several miles per hour faster than others. When you have a lot of ground to cover, a faster mower could shave a significant amount of time off how long it takes you to mow the lawn.

Bear in mind that a mower’s maximum speed is the fastest it can go, and it may not reach that speed on sloped land or uneven terrain. Zero-turn mowers tend to be faster than lawn tractors. 

Price range: Your hard-earned money is important to you, so it’s important to us. We take affordability into account during our ranking process. If a mower is too expensive for the average homeowner to realistically afford, it doesn’t matter how well it works.

Some push lawn mowers can cost close to $1,000, while riding mowers can sometimes reach $10,000. Our top picks strike a good balance between high quality and low budget. 

FAQ About Gas Lawn Mowers

1. Are gas lawn mowers better than electric?

Whether a gas or electric lawn mower is better for you and your yard depends on your needs. Gas lawn mowers are more powerful, but electric lawn mowers are easier to start, lower maintenance, and way better for the environment.

You have to decide what’s most important to you in a lawn mower, then you can decide whether gas or electric is better. 

2. How do you maintain a gas lawn mower?

Just like with a car, your lawn mower’s gas engine will need an oil change every so often. You should change the oil whenever it becomes contaminated or goes cold.

As a general rule of thumb, you need at least one oil change per mowing season. You should also change the air filter and spark plug annually. 

Aside from engine maintenance, it’s smart to clean the undercarriage of your mower throughout the mowing season so it doesn’t get caked in grass and eventually rust.

Sharpening the blade regularly is another must for a long-lasting mower that doesn’t decline in performance over the years. 

3. What happens if you leave gas in a lawn mower over winter?

Leaving old gas in your lawn mower can clog the carburetor and cause the inside of the fuel tank to rust. In many cases, lawn mowers won’t start after sitting with unused gas in the tank for a long period of time.

4. Are gas lawn mowers dangerous?

Any time you’re using and storing a flammable liquid like gas, there’s a certain level of fire hazard. Be careful about how you store your fuel. 

The weight of gas lawn mowers and the high velocity of their blades also can make them more dangerous than electric mowers if you aren’t careful while mowing. 

As with anything else, gas lawn mowers can be dangerous if you don’t take the necessary precautions to prevent mishaps. There’s more potential for danger with gas lawn mowers than electric mowers, but injuries are usually avoidable as long as you stay smart. 

What to do now that you’ve found your perfect gas mower

Finding the perfect gas lawn mower is only the first step to having a perfect lawn. Now that the easy part is over, it’s time to roll up your sleeves and use your new mower once a week throughout spring and summer. 

If you don’t care about having a pristine lawn, you can mow the lawn every two weeks instead. But you shouldn’t go any longer than that during the grass’s growing season. 

Sounds like a lot of work, doesn’t it? It doesn’t have to be. Instead of buying yourself a new lawn mower, put that money toward a professional lawn mowing service that can take care of the lawn for you.

Then you won’t have to worry about which lawn mower to buy or how often to cut the grass. You can leave it all behind and relax while the pros do all the hard work.
