The best gas lawn mowers are designed to make cutting your grass much easier, quicker and more enjoyable. They are ideal garden tools for creating a neat and tidy backyard, not to mention filling the air with the invigorating scent of freshly cut grass. Good gas lawn mowers are easy to use and offer handy features beyond just cutting the grass, while a poor-quality mower will make the entire process more tiresome than needed. 

From our experience, the best gas lawn mowers handle bagging, mulching and discharging with ease, with most designed with a twin blade system to ensure a crisp and precise cut. Unlike the best electric lawn mowers, gas powered mowers use fuel. Generally speaking, they have more powerful engines that are kick-started by pulling a cord or turning an electric key start. It’s this sheer power that makes them popular with people cutting the grass in large gardens. 

In addition, the best gas lawn mowers are easy to maneuver, which is important regardless of whether you have a very large backyard requiring a wide deck, or a slimmer yard best served with a narrow deck. Self-propelled models can be started with the tap of your finger, and enable you to cruise along your lawn thanks to comfy and steady hydrostatic control. These models sometimes have a habit of running away from you though (true story), so we’ve also included self-propelled gas lawn mowers with the option to personalize your walking speed. 

Alternatively, more traditional push models come in a variety of different weights and sizes, often with blade stop technology and adjustable speeds, all to give you greater control over the machine. Although these gas models are powerful and fast, if you have acres of grass ahead of you, consider using one of the best rider lawn mowers instead, as these are built for large green expanses.

Honda HRX217HZA

A self-propelled drive, a powerful 200cc engine and 21-inch twin blades mean this lawnmower will make you the envy of your friends.

SPECIFICATIONS

Depth: 65.6-inches | Height: 42.2-inches | Width: 23.1-inches: | Blade Length: 21-inches | Engine displacement: 200cc **Weight:** 106lbs | Max cutting height: 4-inches | Min cutting height : .75-inches | Drive type: Rear wheel | Mower type: Self propelled | Start type: Electric | Warranty: 5 years residential/lifetime deck

Reasons to Buy

Powerful engine
Electric key start

Reasons to Avoid

Heavy

We've chosen the Honda HRX217HZA as our best overall gas-powered mower because it's got all the features you'll ever need in a mower coupled with that fantastic Honda engine and build quality. 

Let's start with the engine size. At 200cc it's the most powerful engine in our buying guide, matching the Honda HRX217VKA and just a whisper ahead of the Weibang WB537SCV-3IN1. You get twin blades with the Honda HRX217HZA too, and a 4-in-1 Versamow System, which means you can easily switch between mulching, bagging, discharging and leaf-shredding.

The difference between this model and the similarly named Honda HRX217VKA, also in our buying guide, is the addition of Roto Stop technology, which means you can stop the blades without stopping the engine, and Hydrostatic Cruise control for simple, precise control of the mower's speed.

You also get one of our favorite features, which is the electric key start, so there's no cord to pull. Just turn a key and the mower springs into life. In fact, it's hard to think of a feature of a lawnmower that you'd want and that you can't find here. The Honda HRX217HZA might be expensive, but if you pay a little more you get a mower that will last you a lifetime. 


2. Honda HRX217VKA: Best self-propelled gas lawn mower

Honda HRX217VKA

With an impressive feature set and a powerful engine the Honda HRX217VKA lawnmower is one to own.

SPECIFICATIONS

Depth: 63.4-inches | Height: 42.2-inches | Width: 23.1-inches: | Blade Length: 21-inches | Engine displacement: 200cc | Weight: 89lbs | Max cutting height: 4-inches | Min cutting height : .75-inches | Drive type: Rear wheel | Mower type: Self propelled | Start type: pull cord | Warranty: 5 years residential/3 month commercial/lifetime deck

Reasons to Buy

4-in-1 grass cutting features
Self-propelled for easy use

Reasons to Avoid

No electric start
No blade-stop technology

Honda lawnmowers are known for their great engines, and the HRX217VKA features a really powerful 200cc Honda engine. 

The Honda HRX217VKA is self-propelled too, so it's easy to operate and moves forward with just the press of a single finger. There's also an auto choke, so you can be guaranteed a start on the first attempt even if you have to pull a cord. 

The Honda HRX217VKA has twin blades, so you can ensure an amazing cut, and of course, it's got the Honda 4-in-1 Versamow feature set that enables bagging, mulching, discharging and leaf cutting. The twin blades ensure especially fine cuts for mulching.

What we really like with these Honda mowers is that you get a generous 5-year warranty. Not that you'll need it as the user reviews rarely mention mechanical failure.

The HRX217VKA is a great choice for you if you want the majority of the features of the more expensive Honda HRX21HZA, but you want it for over $250 less and you can live without its blade stop technology, electric start, and hydrostatic cruise control.


3. Weibang WB537SCV- 3IN1: Best gas lawn mower for reliability

Weibang WB537SCV- 3IN1

If you're after durability and reliability then the Weibang WB537SCV- 3IN1is a beast of a mower made from quality parts.

SPECIFICATIONS

Depth: 60.4-inches | Height: 39.9-inches | Width: 22.9-inches: | Blade Length: 21-inches | Engine displacement: 196cc | Weight: 120lbs | Max cutting height: 4-inches | Min cutting height : .5-inches | Drive type: Rear wheel | Mower type: Self propelled | Start type: pull cord | Warranty: 5 years residential/1 year commercial

Reasons to Buy

Powerful shaft engine
Blade stop technology

Reasons to Avoid

Heavy
Choke and pull-cord start

You might not be aware of lawnmowers made in other countries, so let us introduce you to the Weibang WB537SCV- 3IN1. As you can see from the pictures, it's a serious professional mower, and if ruggedness and durability are top of your list when choosing a mower, you might want to consider it.

Let's start with the engine. The Weibang has a 196cc shaft-driven engine, which is some serious power under the hood. Belt drives occasionally get twigs stuck in them or suffer from other problems like slippage when wet. In contrast, this shaft-driven engine has a 3-speed gearbox that was specially created for this mower. Everything fits tight in the engine and forget hunting around for the gasoline cap because it is right on top and easy to access. 

There are two separate speed (3 settings) and throttle controls, so you can turn the engine down when you're not really cutting, or to enable you to idle the engine at lower RPS before you shut it off. 

The build quality is outstanding. The deck is made of steel, so it's tough and rugged. The wheels have double ball bearings. There's one lever wheel adjustment, which is really easy to use. But most of all the handle just feels solid when you use it and you hardly feel any vibration at all as you mow.

Quick-release handles mean the main mower handle folds fully down, making it easy to turn the machine upside down to clean or store in your garage. 

The Weibang WB537SCV- 3IN1 ships without oil so you have to provide that yourself. Starting requires a pull cord, and you also need to use a choke. All things considered, the Weibang WB537SCV- 3IN1 is best suited for somebody who is experienced in using garden mowers, and is comfortable with different fuel types and appreciates the beauty of the solid build and high-quality engine. If that sounds like you, then you'll love this mower.


4. Troy-Bilt TB160: Best mid-range gas lawn mower

Troy-Bilt TB160

Here's a mid-range lawnmower that still has a lot power under the hood. The Troy-Bilt TB160 has some great features, too.

SPECIFICATIONS

Depth: 60-inches | Height: 38-inches | Width: 22-inches: | Blade Length: 21-inches | Engine displacement: 160cc | Weight: 69.5lbs | Max cutting height: 3.75-inches | Min cutting height : 1.25-inches | Drive type: Push mower | Mower type: Manual push | Start type: pull cord | Warranty: 2 years

Reasons to Buy

Affordable price
Lightweight

Reasons to Avoid

Manual push
No blade stop system

If you're looking for an affordable gas-powered lawnmower then has all the basic function then the Troy-Bilt 160 is a great mower to consider. Of course, at a price like this you can't expect all the high-end features of something like the Honda HRX217HZA, so it's not self-propelled, and it certainly doesn't have an electric starter, but you do get a really solid 160cc Honda engine.

As well as the reliable engine the Troy-Bilt 160 comes with an Auto-Choke system which means that starting won't be a problem, even if you need to pull a cord. 

The Troy-Bilt 160 does more than just basic grass cutting too. It has a 3 in 1 action, so you get a 1.9-bushel rear bag for normal grass cuttings, but also a mulch kit, and side discharge options with this mower. A specialized cutting blade ensures that mulched grass is finely cut and you'll get a great freshly-cut look for your lawn.

While it's not self-propelled Troy-Bilt has done as much as it can to make it easier to cut with this mower. For instance, the rear wheels are large, at 11-inches, so they'll help you over rough spots in your grass or hills, too. 

Finally, adjusting the height of the cutting blade is easy, thanks to duel levers which give you 6 different height positions. 

The Troy-Bilt TB160 has a number of really good features for its price point, and as one of the cheapest here, it's great value. 


5. Toro 20333: Best gas lawn mower for large yards

Toro 20333

With its extra-wide 22-inch blade, the Toro 20333 is a great choice if you have a large area of grass to mow.

SPECIFICATIONS

Depth: 59-inches | Height: 44-inches | Width: 23-inches: | Blade Length: 22-inches | Engine displacement: 163cc | Weight: 88lbs | Max cutting height: 4-inches | Min cutting height : 1-inch | Drive type: Rear wheel | Mower type: Self propelled | Start type: pull cord | Warranty: 2 years full/3 years to start

Reasons to Buy

Blade stop system
Adjustable speed

Reasons to Avoid

Pull cord start
Single blade

The Toro 2033 is a great choice if you've got a particularly large back yard. The super-wide 22-inch blade means less time mowing and more grass collected as you do so. It's also got a blade stop system, so the blades can be stopped separately to the engine. This means you can keep the engine running, say if you need to move a branch out of the way of your cut, without having to pull the cord again to start it.

Unlike the twin-bladed Honda's in this group test, there's only one blade on the Toro, which means it can't cut the grass as finely for mulching, but it does offer a mulching feature and comes with a bag for collecting clippings.

Another nice addition is what Toro calls "Personal pace", for adjusting the speed of the mower to a pace that suits you. Some self-propelled mowers can go too fast to be comfortable to walk with, so it's a handy feature if you like to walk at your own speed. Or alternatively, you can up the speed and get a little work out while mowing your back yard.

Overall, this mower represents really good value for money, especially if you have a large area to cover. There are some seriously high-end features on offer here for a mid-range price tag.


6. Craftsman M105: Best lightweight gas mower 

best gas lawn mowers: Craftsman M105 mower

(Image credit: Amazon)

Craftsman M105

Made in the US, this lightweight gas mower designed for ease with a 21 inch deck is the perfect solution for medium gardens.

SPECIFICATIONS

Depth: 34.75-inches | Height: 17.75-inches | Width: 23.88-inches | Blade Length: 21-inches | Engine displacement: 140cc | Weight: 65lbs | Max cutting height: 3.75-inches | Min cutting height: 1.25-inches | Drive type: Push mower | Mower type: Manual push | Start type: Pull cord | Warranty: 2-years limited

Reasons to Buy

Lightweight
 Easily adjustable six-position cutting height 

Reasons to Avoid

Engine slightly under-powered 
Some product faults reported online  

If you're searching for a lightweight push lawn mower, then the Craftsman M105 is a brilliant choice. The 21-inch blade means it works best for gardens under a quarter acre, and a six-height adjustable deck and three different clipping disposal options ensures a thorough trim.

Like many of the mid range offerings on this list, the Craftsman doesn't offer two blades in its cutting deck for fine mulching, it still has a three-in-one clipping disposal system. This includes a “mulching” functionality. An extra inclusion with the mower is a “mulch kit”, which improves the nutritional quality of any caught lawn clippings used later for composting. 

The M105 weighs in far less than a lot of its competitors, making it a great option for anyone who does not want to move a 100 lb machine around their garden. Sometimes less is more, especially with a push mower that has none of its own power. While it is easy to move, being a push mower the Craftsman is less suited to hilly gardens than self-powered machines. 

The Craftsman M105 has an auto-choke pull cord engine to minimize any hassle. The dual lever used to operate the cutting deck is also easy to use, making the M105 a fantastic option for medium-sized gardens with a medium-sized price tag.

Although not the cheapest option for a mid-range mower, the Craftsman is a good value proposition regardless. It works especially well for users who want a simple and light lawn care solution.   


7. Toro TimeMaster 21199 mower: Best gas lawn mower for quick cutting

Toro TimeMaster 21199

Save time and effort with the Toro TimeMaster 21199 self-propelling lawn mower that powers through your lawn and mulches too.

SPECIFICATIONS

Weight: 140lb | Dimensions: 65.7in (d) x 32.2in (w) x 44.3in (h) | Max cutting height: 4.25 inch | Min cutting height: 1.25 inch | Cutting width: 30 inches | Mower type: Self-propelled | Start type: Pull-cord | Warranty: three-year full warranty, three-year guaranteed to start

Reasons to Buy

 Powerful engine 
 Wide deck 

Reasons to Avoid

 Fairly expensive 

The Toro TimeMaster 21199 has all the features you need to mow larger yards efficiently, while quickly cutting grass with its wide 30-inch deck. As one of the best self-propelled lawn mowers, it’s also simple to operate with a Personal Pace and Traction Assist feature that ensures the machine operates at a speed that suits you.

Other great features include a Dual-Force Cutting System and Atomic blades, which also slice grass into mulch, plus there’s the option to control your mowing height. The Toro TimeMaster 21199 is practical too with a quick-stow storage handle, and a washout port to easily clean under the deck of the mower. 

As the name suggests, the Toro TimeMaster can significantly reduce the time you spend mowing the lawn, and the 1.2-quart tank averages 45-60 minutes of runtime that will suit most residential lawns of up to an acre.

With its Torque Briggs and Stratton 223cc OHV engine, this best mower is designed to cope with larger residential lawns, but at over $1,000 in price, it might be a little too pricey for smaller backyards. However, if you want plenty of power to cut your mowing time in half with ease then the Toro TimeMaster 21199 is a reliable choice.


8. Cub Cadet SC100HW: Best gas lawn mower for mulching

Cub Cadet SC100HW

If mulching is important to you, consider the fine-cutting blade of the Cub Cadet SC100HW

SPECIFICATIONS

Depth: 60-inches | Height: 38-inches | Width: 22-inches: | Blade Length: 21-inches | Engine displacement: 159cc | Weight: 76lbs | Max cutting height: 3.75-inches | Min cutting height : 1.25-inches | Drive type: Push mower | Mower type: Manual push | Start type: pull cord | Warranty: 3 years

Reasons to Buy

Deck wash system built-in
Tripple cut blade system

Reasons to Avoid

Manual push
No blade-stop system

Like the Troy-Bilt TB160, the Cub Cadet SC100HW is a classic walk-behind mower, but in the distinctive Cub Cadet yellow color, and with some really nice features hidden under the bonnet.

Cub Cadet makes a range of different mowers all the way up to more expensive models with an electric starter button, but this cheaper SC100HW is a pull-start model that has a Sure Start system that guarantees the mower will start in the first or second attempt every time. So, there's no priming or choke operation required when you start the mower, just one pull and you're done. All the user reviews we're read prove that it's a well-supported claim, and there's a healthy 3-year warranty to back it up too. 

The key feature of the Cub Cadet SC100HW is that it has a blade that triple cuts your grass cuttings, making the perfect mulching mower. You get really fine cuttings that will replenish your lawn. So, if mulching is important to you then consider the Cub Cadet SC100HW as a nicely-priced option.

The SC100HW is also a model that's easy to keep clean thanks to a deck wash system that enables you to attach a hose to the mower and run it to keep the underside clean. That sure beats washing the underside manually.

Some customers report that the bag can be a bit messy, letting about 15% of the cuttings fall to the floor when you remove it, but that's a small niggle on what is otherwise a great lawnmower that's a strong contender in the sub-$300 space.


9. Toro 21378 Recycler Lawn Mower: Best gas lawn mower for cutting heights

Toro 21378 Recycler Mower

The Toro 21378 Recycler Lawn Mower is an affordable choice if you want a self-propelling mower that’s flexible too.

SPECIFICATIONS

Weight: 74lb | Dimensions: 40in (d) x 22in (w) x 16in (h) | Max cutting height: 4 inch | Min cutting height: 1 inch | Cutting width: 22in | Mower type: Self-propelled | Start type: Pull-cord | Warranty: two-year full warranty, three-year guaranteed to start

This affordable machine is packed with features too and includes a mulching system that finely shreds grass and puts it back onto your lawn to nourish it. If you wanted to bag the grass instead, then the Toro 21378 also has a quick-connect bagging system that allows you to easily switch from mulching.

The 150cc engine and 22-inch steel deck can take on yards of up to half an acre, with the adjustable handle and lightweight 11-inch rear wheels making it super-easy to control over most lawns. There is also flexibility for precision cutting, and this self-propelling lawn mower has nine positions that will trim between one to four inches.

10. Troy-Bilt TB100: Best budget gas lawn mower

best gas lawn mowers: Troy-Bilt TB100

(Image credit: Troy-Bilt )

Troy-Bilt TB100

You don't need to sacrifice quality if you're shopping on the budget, as this plucky little mower proves.

SPECIFICATIONS

Depth: 60-inches | Height: 38-inches | Width: 22-inches: | Blade Length: 21-inches | Engine displacement: 140cc | Weight: 60 lbs | Max cutting height: 3.75-inches | Min cutting height : 1.25-inches | Drive type: push mower | Mower type: Manual push | Start type: pull cord | Warranty: 2 years

Reasons to Buy

Lightweight
Different cutting heights

Reasons to Avoid

Pull cord start
No bagging option

Mowing your yard can be an important part of your weekly exercise regimen, and if you feel like you need the exercise then it's probably best to stay away from self-propelled mowers. Push mowers are also much cheaper, and if you're shopping on a budget then the price-friendly Troy-Bilt TB100 could be all you need.

Visually it looks very similar to the TB160, which is also in this buying guide, but it has a less-powerful 140cc Briggs & Stratton engine. 

Another difference between the TB160 and this model though is that there's no bagging option with this mower. You only get mulch and side discharge. So, your cuttings are going to stay on your lawn, which might not be good if you want that clean look to your garden. 

As you'd expect for a lightweight mower like this, most of the parts are plastic, so durability may be an issue, but that also means it's easy to transport, which is handy if you need to lift it into a truck. There are lots of positive user reviews and people note that assembly is easy and requires no tools. 

Also on the positive side, there are 6 cutting positions to choose from, with a lever to help you manually adjust between them. You've also got the large rear wheels to help you over the rough spots.

As a rough guide, if you're considering getting a smaller lawnmower like the Troy-Bilt TB100 you're looking at a yard size of under a 1/4 of an acre.


What to look for when buying a gas lawn mower

Engine power: For regular gas-powered mowers the engine size determines the cutting power, but for self-propelled mowers, it almost goes without saying that the more powerful the engine the smoother your mow will be, especially if you need to go up and down bumps or hills. You should consider anything over 160cc engine as very powerful for a lawnmower.

Self-propulsion: the best gas lawnmowers come equipped with self-propulsion technology, which means the mower’s engine can turn the wheels, taking some of the strain off you. It won’t eliminate pushing, but it will make it more tolerable, especially if you need to go uphill.

Mulching: more expensive lawnmowers give you the option to mulch or bag your grass cuttings as well as release them out of the side. Sometimes the condition of your lawn means it would benefit from mulching, so it’s nice to have the option.

Blade width: the width of the cutting blade determines how many passes it takes to mow your yard. A wider blade, like 22-inches, for example, means you spend less time pushing your lawnmower. It's a case of the bigger the better.

Noise level: all internal combustion engines make a lot of noise, but larger engines tend to be louder, so if that's going to be an issue for you then consider a mower with a smaller engine that produces less noise. For context, a quiet model would produce something like 85 decibels of sound.

Cutting height and positions: the best gas lawn mowers allow you to adjust the blade height using levers located on each wheel. Cheaper models tend to require manual adjustment with a screwdriver.

How to maintain a gas lawn mower

With a big purchase like a lawnmower you want something that’s going to last you a good few seasons, so a little bit of maintenance might be required over its lifetime. If you’re in this for the long haul then make sure you follow all the maintenance tips in the owners manual; things like cleaning the air filter, making sure it contains the right mix of fuels, changing the oil regularly, etc, but you might also want to think about how accessible the engine is when making your buying decision. Carburettor issues are the number one cause of a malfunction in a gas-powered lawnmower, or a spark plug may need changing, so how accessible the engine is can make a real difference. 

Starting a gas-powered lawn mower

The standard way to start a gas-powered mower is with a pull-cord. More expensive mowers, however, come with auto choke technology which ensure it starts on the first or second attempt each time. Alternatively, some gas-powered lawnmowers come with an electric starter that just requires you to push a button or turn a key to get them going.

And before we forget - we'd really recommend non-ethanol fuel for a lawnmower if you care about the longevity of your engine. The black charr that forms from ethanol burning is seriously bad news for a small engine.

How much do gas-powered lawn mowers cost?

The price runs from about $160 up to $400 for an affordable or mid-range gas-powered push lawnmower, but higher-end self-propelled models can edge towards the $900 mark and beyond. At the lower end of the market the models are understandably basic, with very few features, but at the top end you get all sorts of wonders, like blade stop technology which will cut out the blades, but leave the motor running, so if you need to move a lump of wood out of the way you can do it without having to stop and restart the mower.
