When purchasing a lawn mower, the engine is perhaps the most critical component to consider. It dictates the performance, efficiency, and longevity of the mower, directly influencing the upkeep of your lawn. This article aims to provide a detailed guide on lawn mower engines.

We will explore the key characteristics of lawn mower engines, such as horsepower, fuel efficiency, and ease of maintenance.

Beyond the mechanics, we’ll also give an overview of the leading lawn mower engine brands and models in 2023. We aim to provide you with a comprehensive understanding of the current market.

What You Need to Know About Lawn Mower engines

When considering lawn mower engines, there are several things to understand that will make it easier for you to pick the right one for your needs.

Firstly, the type of engine matters. Four-stroke engines are the standard for lawn mowers because they are more powerful and fuel efficient then two-stroke engines.

The power of the engine, usually expressed in horsepower (HP) or cubic centimeters (cc), dictates its capability to perform under different mowing conditions. Higher-powered engines can cut thicker grass and manage larger yards, but they tend to cost more and use more fuel.

Fuel efficiency is another important thing to consider when you’re about to buy a lawn mower engine. Engines that use fuel more efficiently can run for longer periods on a single tank of gas, potentially saving money over time.

Reliability and durability are equally crucial. Engines that require fewer repairs and last longer can save you both time and money in the long run.

Finally, the noise level and vibration of the engine can impact the comfort of your mowing experience. Engines designed for quiet operation and reduced vibration are generally more comfortable to use.

One reason for this because they have built up a reputation over a long period of time to be reliable and innovative products.

Despite Briggs & Stratton producing the most lawn mower engines of the four brands, they might not always cater to your specific needs. In fact sometimes and can be useful to compare Briggs & Stratton to Kohler, Honda and Kawasai as they are well known for their high quality. If you’re in the market for a tractor or a zero-turn mower, it might be more beneficial to choose a Kohler or Kawasaki lawn mower engine instead.

With features like an advanced cooling system for optimal temperature maintenance and a pressurized lubrication system for reduced wear and tear, these types of engines are build to last.

They also offer a quieter, smoother operation due to reduced noise and vibration levels, increasing the comfort during extended mowing sessions.


Understanding the intricacies of lawn mower engines is essential in choosing the right machine for your needs. Four-stroke engines dominate the market, offering a balance of power, efficiency, and durability.
