Trimmers are widely used all over the world. They are available in a huge variety, which makes it difficult to choose the right one for you. However, one thing is common among them: they are either 2 cycles or 4 cycles.

If you can choose the right trimmer among 2 cycles and 4 cycles, you will be able to save power, time, and money. In this article, you can learn the difference between these two trimmers and which is the right one for you.

2 Cycle vs. 4 Cycle Trimmer: Factors to Consider


A two-cycle trimmer is equipped with an engine that produces power with every second stroke of its piston. It allows the trimmer to produce more power than a four-cycle trimmer. It produces almost twice the power than its competition.

A four-cycle trimmer is equipped with an engine that produces power with every fourth stroke. It produces half power than a two-cycle trimmer if both trimmers have similar specification engines.


The two-cycle engine trimmer produces more noise than its counterpart, and the reason is obvious. With only two cycles, it results in the combustion of air and gas, which is a small explosion resulting in louder noise.

However, when it comes to a four-cycle trimmer, it is quiet and comfortable for indoor usage. It doesn’t disturb the people around you. It has a dedicated third cycle for combustion, which significantly reduces the noise. Furthermore, it is completely sealed, and outside filters also help in the reduction of noise.


Four-cycle trimmers have many advantages over two-cycle trimmers. However, it’s not the case when it comes to its price. A two-cycle trimmer costs far less than a four-cycle trimmer.

If you don’t have a lot of money to spend on a trimmer, you would probably like to buy a two-cycle trimmer.

Running Cost

A four-cycle trimmer has an advantage when it comes to fuel economy. It requires half the power to give you maximum output as compared to a two-cycle trimmer.

If you want to save money in the long run, you should buy a four-cycle trimmer.


A two-cycle trimmer requires frequent input of oil to ensure its engine safety. However, a four-cycle engine doesn’t need this.

When it comes to long term maintenance, both engines require similar maintenance. You need to spend an equal amount of money, no matter if you have a two-cycle trimmer or a four-cycle trimmer.


While deciding on which trimmer is the right one for you, you need to consider its price, comfort, power, and your usage.

If loud noise concerns you, then you shouldn’t go for a two-cycle trimmer. There is no other option; you should buy a four-cycle trimmer.

A four-cycle trimmer comes with a more expensive price tag. They are heavier in weight as compared to two-cycle trimmers. However, you need far less fuel or electricity to run a four-cycle engine, which saves you a lot of money in the long run.

Lastly, two-cycle trimmers require routine oil maintenance, while four-cycle trimmers require it only when damaged. Apart from oil changes, both require equal maintenance costs.
