When it comes to reliable lawn mower engines Honda, Briggs & Stratton, Toro and PowerSmart have all built good reputations. But as technology has advanced pretty much all lawn mowers now boast reliable engines, do your research and check warranty information and you can’t go wrong…

What You Need to Know About Lawn Mowers

If you have a lawn, then you know that a lawn mower is essential at home.

Sure, you could pay to have your lawn mowed. But it’s just a waste of money. Also, they might not be available the moment you want your lawn mowed. 

Now, think of this:

When you have your own lawn mower, you can cut your grass anytime you need and want.

It may be tiring but think of it as a form of exercise. It’s always great to sweat it out. Getting fresh air in the process is a big plus, too. 

Hear this:

You need to invest in a good lawn mower. That means that you need a piece of equipment with a really efficient engine. 

A lawn mower is not really a cheap machine, so you wouldn’t want it to break down every now and then. 

Is it worth it?

If you buy a functional lawn mower with a truly efficient engine, then it is worth it. 

A lawn mower makes you work faster and it’s so much easier on your body compared to the much-cheaper grass shears. 

It’s easier, too

A lawn mower was designed to make your work simple. 

It has wheels for easy movement. A lawn mower isn’t exactly light, so tires are necessary for mobility. They make for easy navigation so you could cut grass with ease.

In most cases

The tool is a rotary mower. This means that the engine will provide the mower with power so that it will spin a horizontal blade to cut grass. 

The mower cuts the grass as you go. 

There are dozens of lawn mower designs out there from various brands. But for the most part, the basic process is the same. 


The blades are encased within a deck so that the mowed blades will not be flying all over the area. 

There are so many different kinds of lawn mowers. The push mower is the most popular type and it can be powered by gas, electricity or batteries. 

There is also a riding mower, which kind of looks like an ATV (all-terrain vehicle). Oh, let’s not forget about the robotic mower. 

It follows

The bigger the mower, the more powerful the engine should be. 

But whether you have a small mower or a big one, what’s important is that you have a reliable engine so you can cut without problems and your equipment can last for many years. 

What Is the Most Reliable Lawn Mower Engine?

It’s unfair to just name one engine manufacturer here since there are a few reliable engines in the market. 

So, here is our list of the most reliable lawn mower engine (not in any order):


You know this brand as an automobile manufacturer. Honda also manufactures motorcycles and power equipment.

The track record says it loud and clear–Honda knows how to make a reliable engine.

That’s really an important note for people who want to use gas-powered mowers. In most cases, you need to pull the cord more than twice to get the mower started. 

That’s not usually the case with Honda mowers. 

What you need

Whatever kind of mower you are looking for, Honda is sure to have it. The brand has the push or self-propel mowers. 

It even has Miimo, the brand’s robotic lawn mower.


Honda engines, in general, are known to be durable. It’s also the reason why a Honda lawn mower is quite expensive. 

The engine is built to last, so one doesn’t have to pay for repairs or buy a new one in cases of irreparable damage.

To see is to believe

Just one look at the Honda lawn mower or engine and you know you have a long-lasting equipment in your hands (or lawn). 

There is also the fact that the brand aims to always meet environmental standards. That’s always a big plus. 

In relation to that

Honda lawn mowers are fuel-efficient. That’s one reason why it is, in a way, better for the environment compared to its gas-powered counterparts. 

Being fuel-efficient literally means it won’t waste your fuel and your money to buy fuel. 

Briggs & Stratton

Briggs & Stratton has its own line of lawn mowers while also supplying engines to other mowing brands. 

The engine manufacturer has over 20 engines in its lineup.

It also manufactures engines for whatever the other lawn mower brands need. Briggs & Stratton can create engines for the more affordable brands as well as the more expensive ones. 

The company is known as the “largest producer of gasoline engines for outdoor power equipment.”

More importantly, the engine is reliable. 

As the brand states:

“We will make work easier and improve lives by providing innovative products, diverse power solutions and a superior support network.”

It has been in the business for around 110 years. 


Toro has a testing mechanism that is so efficient to ensure that every engine that comes out of the factory will be reliable. 

There is a test under load plus a complete check of the power level to ascertain peak performance.


There are two types of Toro engine for the mower:

  • Single-cylinder engine

The overhead value design also burns cleaner fuel compared to side-valve engines. That’s good for the entire machine and much better for the environment. 


PowerSmart has a wide range of lawn mowers from cordless ones to push mowers and self-propelled lawn mowers. 

The brand’s engines are exclusively made by Amerisun Inc., which is based in Illinois.

The engine manufacturer states:

About those engines

Among the basic lawn mower engines used in PowerSmart equipment are the 127cc, 170cc and 200cc. 

Whatever choice you make, you are sure to have a really reliable engine that is easy to operate. 

What more

It’s really essential to have a highly-functioning engine because a lot of the PowerSmart lawn mowers have multiple functions. 

They don’t just mow the lawn, they also mulches. 

What this means

There is more power needed with a multi-functional system. Also, a solid blade coupled with power makes for a better mulching process. 

Another advantage of the PowerSmart is that it is lightweight. The engine is among the heavier parts of the entire lawn mower so it helps the entire packaging when the most important component is light.

Another important thing

It’s easy to start. That’s always a really great benefit.
