Finding the perfect lawn mower is no small task, and there are many factors to consider if you hope to create the yard of your dreams.
With all different models, sizes, prices and features, it can be daunting to make an informed decision. One of the first things you must consider is whether you want a 2 stroke or 4 stroke lawn mower. With their different designs, operating mechanisms and power sources, it’s important to weigh up their pros and cons before making your decision.
In this article, we’ll discuss the differences between 2 stroke and 4 stroke lawn mowers, and answer the question—which one is best for your lawn?

What is the Difference Between a Two-Stroke and Four-Stroke Engine?
The main difference between two-stroke and four-stroke engines is in the number of strokes that the piston takes complete the combustion cycle.
In two-stroke engines, the piston performs two-strokes: intake and compression to complete the combustion cycle (no exhaust). During the intake, vaporized gas and air is drawn into the combustion chamber, and during the compression, the vapor is compressed to a higher temperature, causing the air to ignite (burn).
In four-stroke engines, the piston performs four strokes: intake, compression, combustion, and exhaust for every complete cycle. In the intake phase, vaporized fuel and air are drawn into the combustion chamber, during combustion this mixture combusts, during the exhaust phase the vapors from the combustion are expelled from the combustion chamber, allowing intake phase to repeat (combustion), compressing the vapors to their ignition temperature.
Benefits of a Two-Stroke Lawn Mower
There are several benefits to using a two-stroke engine in your lawn mower. The first is that a two-stroke engine is lighter and less bulky than a four-stroke motor. This makes them easier to transport and maneuver. Secondly, two-stroke motors have a high power-to-weight ratio, meaning they require less fuel to reach the same power output compared to four-strokes.
In addition, two-stroke mowers are generally easier to start up, as they don’t require converters to reduce their emissions even further.
Benefits of Four-Stroke Mowers
Four-stroke lawn mowers provide several distinct advantages over two-strokes. The main benefit is that they are cleaner, more fuel efficient, and require less maintenance. Since four-strokes have separate oil systems, they don’t release oil or unburnt particles into the atmosphere. Instead, four-strokes run much smoother and generally have higher power-to-weight ratios than two-strokes.
Additionally, four-strokes are much quieter than two-strokes and won’t disturb your neighbors when you mow the lawn. Four-strokes also last longer than two-strokes and require less frequent maintenance, making them a better choice for homeowners who don’t want to spend frequent time and money maintaining their mower.
Which Type of Mower Is Right For You?
When deciding between two- quieter, more fuel efficient, and easier to maintain, a four-stroke may be your better option.
Keep in mind that two- and four-strokes both require an initial investment of time and money to set them up correctly. Both types require regular maintenance to ensure they are running at their best, so factor in the cost of oil, air filters, and other tune-up items into your purchasing decision.
Bottom Line
When it comes down to it, the choice between two-stroke and four-stroke lawn mowers is entirely up to you. Consider your needs and preferences, research each option carefully, and make an informed decision that’s best for you and your garden.
